Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading equipment, in particular to a rotary double-lifting material taking mechanism. Background Art

[0002] The existing reclaiming structure of a product production line has two groups of reclaiming components on the left and right. Since the downstream process of the product requires that the material discharge of the reclaiming structure must meet the simultaneous discharge of two materials on the left and right sides, the two groups of reclaiming components in the existing reclaiming structure are designed to only be lifted and lowered at the same time (single lifting), and the two groups of reclaiming components correspond to two incoming material channels respectively, and cross-reclaiming of two incoming material channels cannot be achieved. Since the incoming material on the belt line is designed as a double channel, when there is only a single channel incoming material, the reclaiming component will not move, and the belt line will continue to flow until the incoming material from the other channel meets the requirement that there are materials in both channels, and then the two reclaiming components will move to pick up the material. This design will cause the incoming material from the first channel to continue to rub against the upper surface of the belt line during the waiting process, which will damage the incoming material surface. The longer the waiting time, the more serious the damage. The incoming material of some production lines is expanded from double channels to three channels. The two groups of reclaiming components in the existing reclaiming structure are only suitable for double channels and cannot meet the use of three channels. Utility Model Content

[0037] Please refer to Figures 1 to 6 A rotating double-lifting material-grabbing mechanism provided in an embodiment of the present application includes a frame 8 and two lifting drive members 1; a first material-grabbing assembly and a second material-grabbing assembly are respectively provided on both sides of the frame 8; the two lifting drive members 1 are respectively installed on the frame 8, one of the lifting drive members 1 is connected to the first material-grabbing assembly to drive the first material-grabbing assembly to move vertically, and the other lifting drive member 1 is connected to the second material-grabbing assembly to drive the second material-grabbing assembly to move vertically.

[0038] In the above technical solution, two lifting drive members are arranged on the frame, and the two lifting drive members are used to respectively drive the first material picking assembly and the second material picking assembly to move vertically up and down. In this way, the material picking assemblies on the left and right sides of the frame can be lifted and lowered separately to pick up materials, thereby realizing that when there is material coming into the flow channel, the material picking assembly picks up the material, and avoiding the problem that when there is only material coming into a single flow channel, the material picking assembly does not pick up the material, resulting in the surface of the incoming material being worn by the belt line.

[0039] According to some embodiments of the present application, the frame 8 includes an upper fixed plate 81 and a lower fixed plate 82, and four guide columns 83 are vertically connected between the upper fixed plate 81 and the lower fixed plate 82. The four guide columns 83 are divided into two groups with the axis of the frame 8, and a guide seat 84 is slidably sleeved on the guide column 83 of each group. The two guide seats 84 are correspondingly connected to the lifting components on the two lifting drive members 1 to drive the guide seat 84 to slide along the guide column 83.

[0040] Specifically, the upper and lower ends of the guide column 83 are fixedly connected with the upper fixed plate 81 and the lower fixed plate 82, respectively, the two guide seats 84 are slidably connected with the two groups of guide columns 83, and the first material picking assembly and the second material picking assembly are connected with the two guide seats 84. The fixed components (the upper and lower ends) on the lifting drive 1 are fixedly connected with the upper fixed plate 81 and the lower fixed plate 82, respectively, and the lifting components (sliding vertically) on the lifting drive 1 are fixedly connected with the guide seats 84. The lifting components on the two lifting drives move up and down, driving the two guide seats to slide along the guide columns, thereby driving the first material picking assembly and the second material picking assembly on the left and right sides of the frame to move vertically, respectively, to achieve separate lifting and picking.

[0041] According to some embodiments of the present application, the rotating dual-lifting material-grabbing mechanism further includes a rotating drive member 2, the rotating component on the rotating drive member 2 is connected to the top of the frame 8, and the rotating drive member 2 is used to drive the frame 8 to rotate, so as to drive the first material-grabbing component and the second material-grabbing component to interchange positions relative to the rotation center. By using a rotating drive member to drive the frame to rotate, the positions of the material-grabbing components on the left and right sides of the frame are interchanged, so that the material-grabbing components on the left and right sides can grab materials from a single flow channel, that is, cross-grabbing can be achieved. That is, the material-grabbing components on the left and right sides of the frame are independently lifted and lowered by two lifting drives, and the rotational transposition function is realized by the cooperation of the rotating drive member, so that the material-grabbing components on both sides can grab materials from the same flow channel.

[0042] According to some embodiments of the present application, the frame 8 is further provided with two translational driving members 3, and the translational driving members 3 are connected to the second material taking assembly to synchronously drive the second material taking assembly to perform translational movement inward or outward relative to the rotation center. By using the translational driving member to drive the material taking assembly on the right side of the frame to perform translational movement, the material taking assembly on the right side of the frame can be extended, so that the material taking range of the right material taking assembly covers two flow channels, which can meet the material taking of three-flow channel incoming materials, so that the entire material taking mechanism can be used for a three-flow channel incoming material belt line.

[0043] According to some embodiments of the present application, two groups of translation guide assemblies are further provided on the frame 8, each group of the translation guide assemblies includes a translation guide rod 4 and a guide sleeve 5, the translation guide rod 4 is connected to the second material-retrieving assembly, and the translation guide rod 4 is slidably sleeved in the guide sleeve 5. Specifically, the guide sleeve 5 is fixedly installed on the guide seat 84 along the horizontal direction, the translation guide rod 4 is slidably sleeved in the guide sleeve 5, and the end of the translation guide rod 4 away from the axis of the frame 8 is fixedly connected to the second material-retrieving assembly. By providing the translation guide assembly, it can play a guiding role when the translation drive member drives the material-retrieving assembly to perform translational motion.

[0044] According to some embodiments of the present application, the rotary double lifting material taking mechanism further includes a transverse moving module 6, which is arranged above the belt line in the transverse direction, and the fixed component on the rotary driving member 2 is connected to the transverse moving component on the transverse moving module 6 through the mounting seat 7. By connecting the rotary driving member with the transverse moving module, the transverse moving module is used to drive the frame to move along the width direction of the belt line, and the two material taking components on the frame move synchronously, so that when the incoming material of the production line is three-channel, the two material taking components can be located above any two adjacent channels.

[0045] According to some embodiments of the present application, the first material picking assembly and the second material picking assembly both include a suction cup bracket 91 and a plurality of vacuum suction cups 92 disposed below the suction cup bracket 91, wherein the suction cup bracket 91 is used to be connected to the two lifting drive members 1, and the vacuum suction cups 92 are used to suck materials. Specifically, the suction cup bracket 91 in the first material picking assembly is directly connected to the guide seat 84, and the suction cup bracket 91 in the second material picking assembly is indirectly connected to the guide seat 84 via the translation guide assembly and the translation drive member 3. A plurality of waist-shaped holes are provided at the lower portion of the suction cup bracket 91, and the vacuum suction cup 92 is mounted on the suction cup bracket 91 via the waist-shaped holes. By providing the waist-shaped holes, the installation position of the vacuum suction cup on the suction cup bracket can be adjusted, so that even if the plurality of vacuum suction cups below the suction cup bracket are not in the same straight line, it is possible to facilitate a better suction operation of the incoming product.

[0046] According to some embodiments of the present application, the two lifting drive members 1 are both rodless cylinders, and the upper and lower ends of the rodless cylinders are fixedly connected to the upper fixed plate 81 and the lower fixed plate 82 respectively, and the lifting parts of the rodless cylinders are fixedly connected to the guide seat 84. The rotating drive member 2 is a rotating cylinder, which can rotate up to 270°, so that the material picking position is flexible. The rotating part of the rotating cylinder is fixedly connected to the upper fixed plate 81 on the top of the frame 8, and the fixed part of the rotating cylinder (cylinder body part) is connected to the transverse moving part on the transverse moving module 6 through the mounting seat 7. The translation drive member 3 is a pen-shaped cylinder, which is mounted on the guide seat 84, and the moving part of the pen-shaped cylinder (cylinder rod) is fixedly connected to the suction cup bracket 91. By adopting the rodless cylinder, the rotating cylinder and the pen-shaped cylinder, the entire material picking mechanism is simple in design, compact in structure, easy to install, and has a moderate overall weight, and can be driven by an ordinary transverse moving module.

[0047] Due to the requirements of the subsequent process, the material discharging mechanism must meet the requirements of discharging two materials on the left and right sides at the same time. Therefore, the rotating double-lifting material discharging mechanism has the following working conditions:

[0048] 1) Three channels have normal material input: The two material-picking components are initially above channel 1 and channel 2, and the material-picking components give priority to the materials from channel 1 and channel 2. When the pen-shaped cylinder extends, it can drive the right material-picking component to the top of channel 3, and can take the materials from channel 1 and channel 3. When there is no material in channel 3, the materials from channel 1 and channel 2 are taken. When there is no material in channel 1, the materials from channel 2 and channel 3 are taken. At this time, the left material-picking component is moved above channel 2 and the right material-picking component is moved above channel 3 by the lateral movement module.

[0049] 2) Only one channel has normal material input: At this time, both the left and right side material taking components are taking materials on this normal material input channel. If channel 1 has normal material input, and channel 2 and channel 3 are abnormal, the left and right side material taking components are in the initial state position. First, the left side material taking component is lifted and lowered alone to take the material from channel 1 and hold it, and then the rotary cylinder rotates 180° to make the right side material taking component above channel 1 and complete the material taking from channel 1. The material taking method is the same when channel 2 is normal, channel 1 and channel 3 are abnormal, or channel 3 is normal, and channel 1 and channel 2 are abnormal.

[0050] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
