Abstract
Description
Technical Field
[0001] This utility model relates to the field of transmission equipment technology, and in particular to a two-stage buffer feeding device. Background Technology
[0002] In existing technologies, robots or linear modules are generally used to pick up and place workpieces. However, the use of robots or linear modules can lead to secondary contamination problems such as suction cup marks during the workpiece picking and placing process.
[0003] Some equipment uses four speed-regulating input mechanisms to transport upstream products side by side, and then uses the first and second conveying modules to merge them into two rows and transport them to the acceleration output mechanism for subsequent steps. Because the products are transported through four parallel speed-regulating input mechanisms, the upstream products are prone to differences such as different workpiece rhythms, which can cause workpieces to stack and lead to equipment blockage. Utility Model Content
[0004] To address the issue of workpiece stacking during transport caused by different upstream workpiece cycle times, this invention proposes a two-stage buffer feeding device.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model proposes a two-stage buffer feeding device.
[0007] Includes: at least two guide conveyor sections arranged in sequence, wherein:
[0008] Each of the guide conveyor sections includes at least two buffer conveyor devices arranged side by side. The output end of the buffer conveyor device of one guide conveyor section corresponds one-to-one with the input end of the buffer conveyor device of the other guide conveyor section. The buffer conveyor device is also provided with a control module, which is used to adjust the conveying speed of the buffer conveyor device and to make the workpieces on the two corresponding buffer conveyor devices spaced apart.
[0009] Furthermore, the buffer conveying device also includes a first track, a plurality of first rotating shafts disposed on the first track, first rollers disposed on both sides of the first rotating shafts, and a sensor disposed on the first track. The control module is connected to the sensor and the first drive mechanism.
[0010] Furthermore, it also includes two first conveying devices, which are disposed on both sides of the conductor conveying section and parallel to the guide conveying section, with the first conveying devices close to the output end of the buffer conveying device.
[0011] Furthermore, each of the first conveying devices includes a second track, a second rotating shaft disposed on the second track, and a second drive mechanism for driving the second rotating shaft, wherein a second roller is disposed on the outer side of the second rotating shaft away from the second track.
[0012] Furthermore, it also includes a second conveying device and an output section. Two second conveying devices are disposed between two first conveying devices. One end of each second conveying device faces the output end of the buffer conveying device, and the other end is close to the input end of the output section.
[0013] Furthermore, the second conveying device includes a third track, a third rotating shaft disposed on the third track, third rollers disposed on both sides of the third rotating shaft, and a third drive mechanism for driving the third rotating shaft.
[0014] Furthermore, the first roller, the second roller, and the third roller are on the same horizontal plane.
[0015] Furthermore, it also includes a guiding device disposed at the top of the first track, the second track, the third track and the top of the output section.
[0016] Furthermore, the guiding device includes multiple guide wheels, which are rotatably disposed on both sides of the first track, the second track, the third track, and the output section.
[0017] Furthermore, the output section is parallel to the first conveying device, and the output end of the output section is aligned with the downstream equipment.
[0018] The beneficial effects of this utility model are:
[0019] (1) The two-stage buffer feeding device proposed in this utility model has two sequentially arranged guide conveying sections. After the sensor of the upstream buffer conveying device is triggered, the drive mechanism of the buffer conveying device will start and stop according to whether the downstream buffer conveying device senses the workpiece, thereby widening the distance between the upstream and downstream workpieces. The two buffer conveying devices can better control the rhythm and distance of the workpieces and prevent the workpieces from stacking and blocking the equipment.
[0020] (2) The two-stage buffer feeding device proposed in this utility model uses the first conveying device to combine the four-channel buffer conveying device into the two-channel conveying device, which can complete the convergence of four tracks to two tracks and can directly connect to downstream equipment without setting up a material picking and unloading device.
[0021] (3) The two-stage buffer feeding device proposed in this utility model uses a rotatable guide wheel to guide the workpiece. When the workpiece moves in contact with the guide wheel, the guide wheel will rotate, thereby reducing the friction between the guide wheel and the workpiece. On the one hand, it will not cause scratches to the workpiece, and on the other hand, it is not easy to cause guide failure and equipment blockage. Attached Figure Description

[0029] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0030] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.
[0031] In existing technologies, products are transported upstream side-by-side using four speed-regulating input mechanisms, and then transported to an acceleration output mechanism for subsequent steps using a first and second conveying module. Because the products are transported via four parallel speed-regulating input mechanisms, differences in the workpiece cycle time can easily occur, leading to workpiece stacking and equipment blockage. Furthermore, if the fixed guide device is softer than the workpiece, pits can form on the guide device after prolonged operation, preventing subsequent workpieces from being properly guided and causing blockages; conversely, if the guide device is harder than the workpiece, it can cause scratches on the workpiece. Therefore, this invention is proposed.
[0032] Please refer to Figure 1-6 This utility model proposes a two-stage buffer feeding device comprising at least two sequentially arranged guide conveyor sections 1, wherein:
[0033] Each guide conveyor section 1 includes at least two buffer conveyor devices 11 arranged side by side. The output end of the buffer conveyor device 11 of one guide conveyor section 1 corresponds one-to-one with the input end of the buffer conveyor device 11 of the other guide conveyor section 1. The buffer conveyor device is also equipped with a control module, which is used to adjust the conveying speed of the buffer conveyor device and make the workpieces on the two corresponding buffer conveyor devices spaced apart.
[0034] Specifically, refer to Figure 1 The buffer conveyor 11 has input and output workpieces on both sides, namely the output end and the input end. When there are many workpieces, the control module controls the conveying speed of the two corresponding buffer conveyors 11. The buffer conveyor 11 temporarily buffers the workpieces, thereby increasing the distance between the workpieces and preventing the workpieces from stacking and blocking.
[0035] In one embodiment, two or more guide conveyor sections 1 can be set according to the actual situation to make the workpieces 5 spaced apart and control the cycle time of the workpieces 5.
[0036] Furthermore, the buffer conveying device 11 also includes a first track 111, a plurality of first rotating shafts 112 disposed on the first track 111, first rollers 113 disposed on both sides of the first rotating shafts 112, and a sensor 114 disposed on the first track 111. The control module is connected to the sensor 114 and the first drive mechanism.
[0037] Specifically, refer to Figure 1 , 26. The first drive mechanism includes a first drive shaft located at the bottom of the first track 111 and in the same conveying direction as the first track 111, and a motor that drives the first drive shaft to rotate. Magnetic wheels are provided on the first drive shaft and the first rotating shaft 112. The rotation of the first drive shaft drives the rotation of the first rotating shaft 112 through the magnetic wheels. The first rotating shaft 112 drives the first roller 113 to rotate to complete the conveying of the workpiece 5. Eight buffer conveying devices 11 are arranged in a 4*2 configuration to form two guide conveying sections 1. The workpiece 5 is conveyed sequentially through the left and right guide conveying sections 1. When the sensor 114 of one buffer conveying device 11 is triggered by the workpiece 5, the first drive mechanism of the buffer conveying device 11 will automatically start and stop according to whether there is a workpiece 5 on the track and whether there is a workpiece 5 on the downstream buffer conveying device 11. This will keep the workpieces 5 on the two buffer conveying devices 11 apart, preventing the workpieces 5 from colliding on the guide conveying section 1. At the same time, since the interval between the upstream conveyed workpieces 5 is inconsistent, the two buffer conveying devices 11 can temporarily buffer the workpieces, which can reduce the impact on the cycle time and prevent the workpieces 5 from stacking and blocking the equipment.
[0038] In one embodiment, two or more guide conveyor sections 1 can be set according to the actual situation to make the workpieces 5 spaced apart and control the cycle time of the workpieces 5.
[0039] Furthermore, it also includes two first conveying devices 2, which are arranged on both sides of the wire conveying section and parallel to the guide conveying section 1, with the first conveying devices 2 close to the output end of the buffer conveying device 11.
[0040] Specifically, the two first conveying devices 2 convey the workpiece 5 in a straight line. The workpiece 5 is conveyed by the first conveying device 2 to the second conveying device 3 for merging, and then the workpiece 5 is conveyed to the downstream equipment through the output section 6.
[0041] Furthermore, each first conveying device 2 includes a second track 21, a second rotating shaft 23 disposed on the second track 21, and a second driving mechanism for driving the second rotating shaft 23. A second roller 22 is disposed on the side of the second rotating shaft 23 away from the second track 21.
[0042] Specifically, refer to Figure 1-3The first conveying device 2 is similar to the buffer conveying device 11. The second drive mechanism drives the second drive shaft under the second track 21 to rotate, and drives the second rotating shaft 23 to rotate through the magnetic gear on the second drive shaft, so that the second roller 22 rotates to transport the workpieces 5 from the output ends of the two outer first tracks 111 to the second conveying device 3. The second roller 22 is provided on the side of the second rotating shaft 23 away from the second track 21 and close to the second conveying device 3. Each first conveying device 2 is controlled to start and stop by a second drive mechanism, so that the two devices do not affect each other and the workpieces 5 are transported more smoothly.
[0043] Further, please refer to Figure 1 It also includes a second conveying device 3 and an output section 6. The two second conveying devices 3 are arranged between the two first conveying devices 2. One end of the two second conveying devices 3 faces the output end of the buffer conveying device 11, and the other end is close to the input end of the output section 6.
[0044] For details, please refer to Figure 1 and 4 The second conveying device 3 is used to convey the workpiece 5 to the output section 6. The two second conveying devices 3 are arranged in a V-shape. One end of the two second conveying devices 3 is aligned with the output end of the two inner buffer conveying devices 11, and the other end is aligned with the input end of the output section 6. The buffer conveying devices 11, together with the first conveying device 2, gather the workpiece 5 onto the second conveying device 3, completing the convergence of four track conveyings into two track conveyings. The convergence onto the output section 6 can directly connect to the downstream equipment without the need to set up a material handling device to convert the four rows of tracks into two rows of track conveyings.
[0045] Further, please refer to Figure 4 The second conveying device 3 includes a third track 31, a third rotating shaft 33 disposed on the third track 31, third rollers 32 disposed on both sides of the third rotating shaft 33, and a third drive mechanism for driving the third rotating shaft 33.
[0046] Specifically, the second conveying device 3 works on the same principle as the buffer conveying device 11. The third drive mechanism drives the third drive shaft under the third track 31 to rotate, and drives the third rotating shaft 33 to rotate through the magnetic gear on the third drive shaft, so that the third roller 32 rotates to convey the workpiece 5 conveyed by the two first tracks 111 on the inner side.
[0047] Furthermore, the first roller 113, the second roller 22, and the third roller 32 are on the same horizontal plane.
[0048] Specifically, the first roller 113, the second roller 22, and the third roller 32 are set at the same height, which allows the workpiece 5 to slide smoothly onto each roller and be transported to the downstream equipment under the action of the rollers.
[0049] Furthermore, it also includes a guide device 4, which is disposed on the top of the first track 111, the second track 21, the third track 31 and the output section 6.
[0050] For details, please refer to Figure 6 The guide wheel 41 is used to guide the workpiece 5 so that the workpiece 5 can be transported smoothly. The guide device 4 on the first track 111 prevents the workpiece 5 from deviating from the track. The guide device 4 on the second track 21 guides the workpiece 5 so that the workpiece 5 gathers on the third track 31. The guide device 4 on the third track 31 further guides the workpiece 5 so that it is parallel to the transport direction of the track.
[0051] Furthermore, the guiding device 4 includes a plurality of guide wheels 41, which are rotatably disposed on both sides of the first track 111, the second track 21, the third track 31 and the output section 6.
[0052] For details, please refer to Figure 5-6 Compared to using a spring sheet for guidance, which can cause friction between the spring sheet and the workpiece 5 and scratch the workpiece 5, when a guide wheel 41 is used, the workpiece 5 moves in contact with the guide wheel 41 and drives the guide wheel 41 to rotate, reducing the scraping friction of the guide wheel 41 when guiding the workpiece 5, and making it less likely to cause guidance failure and equipment blockage.
[0053] Furthermore, the output section 6 is parallel to the first conveying device, and the output end of the output section 6 is aligned with the downstream equipment.
[0054] Specifically, the output section 6 has the same structure as the second conveying device. The workpiece is gathered on the second conveying device through the first conveying device, and then guided to the output section 6 by the second conveying device in conjunction with the guide wheel. The output section 6 is then aligned with the downstream equipment.
[0055] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
