Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loading and unloading equipment, in particular to an air blowing clamp loading component. Background Art
[0002] The feeding tube loading and unloading machine is provided with a feeding assembly for delivering the chips in the tube into the feeding track. The feeding assembly includes an air blowing gripper, which is used to deliver the chips carried by the tube into the track on the feeding side of the sorting machine. On the one hand, the air blowing gripper needs to ensure position compatibility with the tube delivered by the feeding push tube slot, and on the other hand, the chips in the tube need to be delivered into the feeding track by blowing air, ensuring that the chips can smoothly enter the track in the tube. The above process has high requirements on the sealing of the cavity between the air blowing gripper and the tube and the air flow rate. If a good sealed cavity cannot be formed or the air flow rate is insufficient, problems such as the chip getting stuck in the tube or the feeding track being short of material will occur. At the same time, in the calibration and positioning of the tube, it is necessary to ensure that the tube is always level, and no collision can occur when the feeding push tube slot pushes the tube to this position.
[0003] The existing air blowing gripper does not have a calibration and positioning function. It increases the air cavity to accommodate the position of the material tube, resulting in a large air cavity space, poor sealing, and large air loss. Secondly, the existing air blowing gripper has only one air hole, and the air cavity of the upper air blowing gripper is relatively wide. The air volume is insufficient for heavy and large chips, which can easily lead to problems such as difficulty in loading and easy jamming of chips in the material tube, affecting production efficiency.
[0004] Therefore, there is an urgent need to provide an air blowing gripper loading assembly that can solve at least one of the above technical problems. Utility Model Content
[0005] The utility model aims to provide a blowing gripper loading component, which has a certain calibration and positioning function for the uncertainty of the position of the material pipe at the loading position. The air cavity formed between the blowing upper gripper and the blowing lower gripper does not need to be designed to be too large, which is conducive to sealing and reduces air loss.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] The utility model provides an air blowing gripper loading component, comprising an air blowing upper gripper and an air blowing lower gripper;
[0008] The blowing upper gripper comprises an upper gripper body and a calibration part connected to the upper gripper body, the upper gripper body is recessed with a blowing groove, the calibration part is recessed with a guide groove arranged along the length direction of the material pipe opposite to the blowing groove, the slot width of the guide groove is greater than the slot width of the blowing groove, the slot height of the guide groove is lower than the slot height of the blowing groove, the slot of the guide groove is formed with a primary guide cavity toward the bottom of the slot, the slot of the blowing groove is formed with a secondary guide cavity toward the bottom of the slot, and the primary guide cavity is used to guide the material pipe into the secondary guide cavity along the height direction of the material pipe;

When in use, the blowing upper gripper gradually approaches the material pipe on the blowing lower gripper, and since the notch of the guide groove is lower than the notch of the blowing groove, and the notch width of the guide groove is greater than the notch width of the blowing groove, the material pipe will enter the guide groove first, and if the material pipe deviates in its own width direction, the primary guide cavity will guide the material pipe, and preliminarily calibrate the position of the material pipe in the width direction, and as the distance between the blowing upper gripper and the material pipe gradually decreases, under the guidance of the primary guide cavity, the material pipe enters the secondary guide cavity, and is calibrated in place under the guidance of the secondary guide cavity, and at this time, the upper gripper body and the blowing lower gripper clamp the material pipe together.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0034] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0035] This embodiment provides a blowing clamp loading component, such as Figure 1 and Figure 2 As shown, it includes an air-blowing upper gripper and an air-blowing lower gripper 5; the air-blowing upper gripper includes an upper gripper body 1 and a calibration portion 2 connected to the upper gripper body 1, the upper gripper body 1 is recessed with a blowing groove 11, the calibration portion 2 is recessed with a guide groove 21 arranged along the length direction of the material pipe 3 and opposite to the blowing groove 11, the groove width of the guide groove 21 is greater than the groove width of the blowing groove 11, the groove height of the guide groove 21 is lower than the groove height of the blowing groove 11, the groove of the guide groove 21 is retracted into a primary guide cavity 211 toward the groove bottom, the groove of the blowing groove 11 is retracted into a secondary guide cavity 111 toward the groove bottom, the primary guide cavity 211 is used to guide the material pipe 3 into the secondary guide cavity 111 along the height direction of the material pipe 3; the air-blowing lower gripper 5 is arranged opposite to the upper gripper body 1 along the height direction of the material pipe 3.
[0036] by Figure 2 The use process of the above-mentioned blowing clamp feeding assembly is specifically described by taking an example. The feeding pushing pipe assembly pushes the material pipe 3 to the feeding position, and pushes the material pipe 3 to the track entrance through the pushing pipe cylinder; the blowing lower clamp 5 first pushes up to support the material pipe 3, and then the blowing upper clamp presses downward. During the downward pressing process, the primary guide cavity 211 first provides guidance to calibrate and position the material pipe 3 with a large left-right position deviation. As the blowing upper clamp is gradually pressed downward, the lower material pipe 3 gradually enters the secondary guide cavity 111 under the guidance of the primary guide cavity 211, and the secondary guide cavity 111 continues to correct the position of the material pipe 3 until the material pipe 3 completely enters the blowing groove 11 to prevent the upper clamp body 1 from pressing on the material pipe 3, and then relies on the gas released from the blowing groove 11 to provide power to deliver the chip into the feeding track.
[0037] The blowing upper clamp provided in the above embodiment is provided with a primary guide cavity 211 and a secondary guide cavity 111. The material pipe 3 is gradually calibrated into place through the two guides. By successively guiding the material pipe 3, the guiding effect on the material pipe 3 is ensured while reducing the width of the blowing slot 11 and reducing the gas loss, thereby solving the compatibility problem of the position of the material pipe 3.
[0038] In addition, since the guide groove 21 is independently provided on the calibration part 2, the calibration part 2 is used as follows. Figure 3As shown, there is no need to abut against the lower air-blowing gripper 5, so the notch of the guide groove 21 can be set lower, giving priority to guiding the material tube 3. Compared with the guide groove 21 and the air-blowing groove 11 being combined into a groove body and set on the upper gripper body 1, there is no need to open a deeper guide cavity on the upper gripper body 1, which will not cause the cavity size formed between the upper gripper body 1 and the air-blowing lower gripper 5 to be larger, which is conducive to sealing and reduces gas loss. At the same time, in order to avoid interference between the calibration part 2 and the air-blowing lower gripper 5, an avoidance groove is set between the calibration part 2 and the side of the upper gripper body 1 facing the air-blowing lower gripper 5.
[0039] It should be noted that the shapes of the primary guide cavity 211 and the secondary guide cavity 111 can be of various shapes, that is, any shape that allows the material tube 3 to smoothly enter the secondary guide cavity 111 and be calibrated into place under the guidance of the primary guide cavity 211 is acceptable.
[0040] In at least one embodiment, in order to facilitate processing and ensure smooth movement of the material tube 3 during the calibration process, as Figure 1 As shown, the primary guide cavity 211 and the secondary guide cavity 111 are both trumpet-shaped. Specifically, the openings of the primary guide cavity 211 and the secondary guide cavity 111 gradually increase in a direction approaching the notch.
[0041] In addition, if Figure 1 As shown, the guide groove 21 and the blowing groove 11 are relatively arranged in the center along the length direction of the material tube 3, that is, along the length direction of the material tube 3, the first center line 213 on the cross section of the guide groove 21 coincides with the second center line 113 on the cross section of the blowing groove 11.
[0042] In some embodiments, the primary guide cavity 211 includes two first guide slopes 2111 disposed opposite to each other along the width direction of the material tube 3. Figure 4 As shown, the included angles between the two first guiding inclined surfaces 2111 and the notch of the guide groove 21 are the same, and no matter the material tube deviates to the left or to the right, the first guiding inclined surfaces 2111 can correct the position of the material tube 3.
[0043] In some embodiments, the secondary guide cavity 111 includes two second guide slopes 1111 arranged opposite to each other along the width direction of the material tube 3. Figure 4 As shown, the included angles between the two second guide slopes 1111 and the notch of the blowing slot 11 are the same, and no matter the material pipe deviates to the left or to the right, the second guide slopes 1111 can correct the position of the material pipe 3.
[0044] The first guiding inclined surface 2111 and the second guiding inclined surface 1111 may be parallel or non-parallel.
[0045] In at least one embodiment, Figure 4 As shown, the first guiding bevel 2111 is parallel to the second guiding bevel 1111. After the first guiding bevel 2111 corrects the position of the material tube 3, the upper gripper body 1 moves down a certain distance, the material tube 3 will contact the second guiding bevel 1111, and the second guiding bevel 1111 begins to further correct the position of the material tube 3.
[0046] In the above embodiment, if Figure 4 As shown, it can be understood that, in the height space where the first guide bevel 2111 and the second guide bevel 1111 coexist, the distance between the first guide bevels 2111 at any height is smaller than the distance between the two second guide bevels 1111 at the same height, so that the material tube 3 can smoothly enter the secondary guide cavity 111 under the guidance of the first guide bevel 2111 and contact the second guide bevel 1111.
[0047] In some embodiments, Figure 4 As shown, the top of the first guide slope 2111 is the first end, the top of the second guide slope 1111 is the second end, the distance between the first ends of the two first guide slopes 2111 is greater than the distance between the second ends of the two second guide slopes 1111. Since the first guide slope 2111 is parallel to the second guide slope 1111, the height of the first end will be lower than the height of the second end.
[0048] In some embodiments, Figure 1 As shown, the guide groove 21 also includes a first material tube accommodating cavity 212 extending from the end of the primary guide cavity 211 away from the groove opening to the groove bottom. The material tube 3 will enter the first material tube accommodating cavity 212 under the guidance of the primary guide cavity 211.
[0049] Specifically, the width of the first material tube accommodating cavity 212 at any depth is the same, so that it can be adapted to the shape of the side wall of the material tube 3 and better accommodate the material tube 3.
[0050] In some embodiments, the blowing slot 11 further includes a second material tube accommodating chamber 112 extending from the end of the secondary guide chamber 111 away from the slot opening to the bottom of the slot, and the material tube 3 enters the second material tube accommodating chamber 112 under the guidance of the secondary guide chamber 111 .
[0051] Specifically, the width of the second material tube accommodating cavity 112 at any depth is the same, so that it can be adapted to the shape of the side wall of the material tube 3 to better accommodate the material tube 3.
[0052] In some embodiments, Figure 1 As shown, an upper sealing layer 4 is provided in the second material tube accommodating cavity 112 .
[0053] The upper sealing layer 4 can compensate for the gap between the upper gripper body 1 and the material tube, thereby ensuring the sealing between the extrusion surfaces of the two.
[0054] Specifically, the upper sealing layer 4 can be made of a rubber-plastic sponge board.
[0055] In some embodiments, Figure 5 As shown, the upper gripper body 1 is provided with a first air inlet hole 12 and a second air inlet hole 13 , and both the first air inlet hole 12 and the second air inlet hole 13 are communicated with the blowing groove 11 .
[0056] In the above embodiment, exhausting air into the blowing slot 11 through the double air inlet holes can increase the air pressure in the blowing slot 11 and avoid the phenomenon of insufficient blowing volume.
[0057] In some embodiments, Figure 3 As shown, the upper gripper body 1 and the calibration part 2 can be integrally formed, or can be formed as Figure 6 As shown, the upper grip body 1 and the calibration part 2 are independently provided and are detachably connected. Specifically, the calibration part 2 can be connected to the upper grip body 1 by means of connecting members such as screws.
[0058] In some embodiments, Figure 3 As shown, a lower sealing layer 6 is provided on the surface of the lower blowing gripper 5 facing the upper gripper body 1 , and the lower sealing layer 6 can ensure the sealing of the extrusion surface between the lower blowing gripper 5 and the upper gripper body 1 .
[0059] Specifically, the lower sealing layer 6 can be made of a rubber-plastic sponge board.
[0060] When in use, since the rubber-plastic sponge board has a certain compressibility, the lower clamp 5 can be lifted up by blowing, and after the upper clamp is pressed down by blowing, a certain interference is formed between the upper clamp and the lower sealing layer 6, thereby ensuring the sealing of the contact. At the same time, the material tube 3 and the upper sealing layer 4 can also form a relatively good sealing through compression, thereby forming a sealed air cavity with a certain pressure, so that the gas is discharged along the material tube 3 through the tail end of the material tube 3 to drive the components into the track cavity.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
