Description

Technical Field

[0001] The utility model relates to the technical field of package yarn dyeing and dehydration auxiliary equipment, in particular to a package yarn supporting mechanism and a material taking and placing device composed thereof. Background Art

[0002] Package yarn dyeing usually includes the following processes: trough drum - loading into the vat - dyeing - unloading from the vat - dehydration - packaging, etc. It is a labor-intensive industry. Most of the processes require multiple people to do manual work. The factory environment is hot and humid, the workers consume a lot of physical energy and the work intensity is high.

[0003] Among them, during the dehydration process, the bobbin yarn needs to be placed in the dehydrator, and then the bobbin yarn needs to be taken out of the dehydrator after the dehydration is completed. The existing dehydrator storage part is composed of several cylindrical storage barrels, and each cavity can vertically stack multiple bobbin yarns. Before dehydration, workers manually load the unloaded bobbin yarn into the cylindrical storage barrel of the dehydrator, and the dehydrator dehydrates the bobbin yarn. Because the gap between the cylindrical storage barrel and the outer circle of the bobbin yarn is relatively small, it is impossible to use tools to quickly take out the bobbin yarn after dehydration. Therefore, after the dehydration is completed, the workers can only take out the bobbin yarn in the cylindrical storage barrel one by one from top to bottom. The labor intensity of the workers is high, which also greatly affects the work efficiency. In addition, in order to facilitate workers to take out the yarn bobbins, the diameter of the current yarn bobbins dehydrator cannot be too large, generally around 1.7-2 meters, and the cylindrical storage barrel cannot be too deep, generally only about 4 yarn bobbins can be stacked, otherwise it will be more difficult for workers to take out the materials. It can be seen that the current way of taking yarn bobbins seriously affects the capacity of the dehydrator, resulting in low production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0048] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0049] Example 1

[0050] This embodiment discloses a bobbin yarn supporting mechanism, such as Figure 1 As shown, the bobbin yarn supporting mechanism includes a lifting rod assembly 100 and a supporting assembly 200 , and the supporting assembly 200 is connected to the lower end of the lifting rod assembly 100 .

[0051] like Figure 4 , 5 As shown, the support assembly 200 includes a support seat 210 and at least two support claws 220, and the support claws 220 are evenly distributed on the support seat 210 in the circumferential direction, and are used to support the bobbin yarn. In order to support the bobbin yarn more stably, the number of the support claws 220 in this embodiment is set to three.

[0052] Among them, the supporting claws 220 are movably arranged on the supporting seat 210, that is, the supporting claws 220 can swing up and down. When all the supporting claws 220 swing upward and are in a nearly horizontal state or can support the bobbin yarn, the supporting claws 220 are in an expanded state; when all the supporting claws 220 swing downward and are in a vertical state or can allow the bobbin yarn to fall from above the supporting claws 220, the supporting claws are in a retracted state.

[0053] In order to enable the supporting claw 220 to swing up and down, specifically, as Figure 5 As shown, the support base 210 is provided with a plurality of bayonet holes 211 in the circumferential direction, the side walls on both sides of the bayonet holes 211 are provided with pin holes, and the connecting end of the support claw 220 is provided with a plug hole. When installing, the connecting end of the support claw 220 is inserted into the bayonet hole 211, and then the pin is passed through the pin hole on the support base 210 and the plug hole on the support claw 220, so that the support claw 220 can be installed on the support base 210 through the pin, and the support claw 220 can swing up and down with the pin as the fulcrum.

[0054] In addition, an annular groove is provided on the outer periphery of the support seat 210, and the annular groove is connected to the upper end of the bayonet 211, and a spring 212 is installed in the annular groove. The spring 212 serves to limit and buffer the support claw 220. When the support claw 220 swings upward and approaches a horizontal state, the upper surface of the support claw 220 will abut against the spring 212 and cannot continue to swing upward, thereby limiting the support claw 220; at the same time, since the spring 212 has a certain deformation characteristic, when the support claw 220 abuts against the spring 212, the support claw 220 is buffered due to the deformation characteristic of the spring 212.

[0055] The support base 210 is provided with a through hole, and the bayonet 211 is connected to the through hole; the connecting end of the support claw 220 is provided with a protrusion 221, and the protrusion 221 extends into the through hole. Through the above structure, when the protrusion 221 is subjected to a downward extrusion force, the support claw 220 can swing upward with the pin as a fulcrum, thereby entering the expanded state; when the downward extrusion force on the protrusion 221 disappears, the support claw 220 swings downward under the action of its own gravity, thereby entering the retracted state.

[0056] like Figure 2As shown, the lifting rod assembly 100 includes an outer sleeve 110 and an inner pull rod 120 disposed inside the outer sleeve 110. There is a clearance fit between the outer sleeve 110 and the inner pull rod 120, so the inner pull rod 120 can move up and down inside the outer sleeve 110. The lower end of the outer sleeve 110 is connected to the support seat 210, and the connection between the two can be a fixed connection or a detachable connection. In this embodiment, the outer sleeve 110 and the support seat 210 are detachably connected by threads. When the outer sleeve 110 is connected to the support seat 210, the inner pull rod 120 is coaxial with the through hole on the support seat 210, that is, the lower end of the inner pull rod 120 can be inserted into the through hole on the support seat 210, so that the lower end of the inner pull rod 120 can squeeze the protrusions 221 of the multiple support claws 220 downward, so that the multiple support claws 220 are flipped upward at the same time and enter the expanded state, as shown in FIG. Figure 6 A limiting boss 121 is provided at the lower end of the inner rod 120. When the lower end of the inner rod 120 is inserted into the through hole on the support seat 210 and the support claw 220 is in the unfolded state, the limiting boss 121 on the inner rod 120 just abuts against the top of the support seat 210 so that the inner rod 120 cannot be further inserted downward into the through hole on the support seat 210. In this way, the inner rod 120 is limited and the upward flipping angle of the support claw 220 can be limited.

[0057] like Figure 2 , 3 As shown, the inner pull rod 120 is provided with a support boss 122, and a thrust spring 140 is provided above the support boss 122. The thrust spring 140 can be sleeved on the inner pull rod 120, and its lower end abuts against the support boss 122; in addition, the thrust spring 140 can also be directly provided on the support boss 122, that is, the thrust spring 140 does not need to be sleeved on the inner pull rod 120. A lifting head 130 is provided at the upper end of the outer sleeve 110, and the upper end of the thrust spring 140 abuts against the lifting head 130, and the thrust spring 140 can be limited from above by the lifting head 130. In specific implementation, the lifting head 130 can be detachably connected to the outer sleeve 110 through a thread, so that the inner pull rod 120 can be placed in the outer sleeve 110. A through hole is provided on the pulling head 130 , and the top of the inner pull rod 120 passes through the through hole on the pulling head 130 and extends upward out of the outer sleeve 110 .

[0058] In addition, the lifting head 130 is provided with a second clamped portion 131, and the top of the inner pull rod 120 is provided with a first clamped portion 123. In specific implementation, the second clamped portion 131 and the first clamped portion 123 can be set according to the situation of the external clamp to match the shape of the clamping portion of the clamp; for example, the second clamped portion 131 and the first clamped portion 123 can be set to be spherical, plate-shaped or clamping grooves.

[0059] When in use, under the downward thrust of the thrust spring 140, the inner pull rod 120 is inserted downward into the perforation of the support seat 210, and the support claw 220 is in an expanded state, so that a plurality of bobbins are sleeved on the outer sleeve 110, and the bobbins are supported on the bobbins support mechanism. The second clamped portion 131 is clamped by an external clamp, and the entire bobbins support mechanism is lifted and placed into the storage barrel of the dehydrator, and the dehydrator dehydrates the bobbins. When the bobbins are dehydrated, the entire bobbins support mechanism is lifted out of the storage barrel of the dehydrator by a clamp and transferred to the unloading area. At this time, the clamp clamps the first clamped portion 123 and lifts the inner pull rod 120 upward. The support claw 220 is no longer subjected to the downward squeezing force of the inner pull rod 120 and enters a contracted state, and the bobbins fall from the bobbins support mechanism to complete the unloading. Compared with the traditional operation method of manually putting yarn cones into and taking them out of the storage drum of the dehydrator one by one, the yarn cone support mechanism of this embodiment can carry multiple yarn cones at a time, so that multiple yarn cones can be conveniently put into and taken out of the cylindrical storage drum of the dehydrator at one time, thereby improving the operation efficiency and reducing the labor intensity; at the same time, it is also conducive to increasing the height of the cylindrical storage drum of the dehydrator to increase the capacity of the dehydrator, thereby improving the efficiency of the dehydrator.

[0060] Example 2

[0061] This embodiment discloses a material taking and placing device, which includes the bobbin yarn supporting mechanism in the above-mentioned embodiment 1, and a pneumatic clamp matched with the bobbin yarn supporting mechanism.

[0062] like Figure 7 As shown, the pneumatic clamp includes: a mounting base 300 , a lifting plate 500 , a lifting cylinder 700 and a pneumatic clamping assembly 400 .

[0063] The lifting plate 500 is arranged on the mounting seat 300 in a liftable manner; specifically, a guide column 600 can be arranged on the mounting seat 300, and the lifting plate 500 can be installed on the mounting seat 300 through the guide column 600, and there is a clearance fit between the lifting plate 500 and the guide column 600, so that the lifting plate 500 can be lifted up and down along the guide column 600; when specifically set, a graphite copper sleeve can be arranged between the lifting plate 500 and the guide column 600 to reduce the damage caused by friction between the two. Of course, the lifting plate 500 can also be installed on the mounting plate in a liftable manner in other ways, such as the installation and matching method of the slide rail and the slider.

[0064] The lifting cylinder 700 is used to push the lifting plate 500 up and down. It can be installed on the mounting seat 300, and the telescopic end is connected to the lifting plate 500. By controlling the telescopic end to extend and retract, the lifting plate 500 can be driven to move up and down. In addition, the lifting cylinder 700 can also be installed on the lifting plate 500, and its telescopic end is connected to the bottom plate of the mounting seat 300. When the telescopic end is extended and retracted, the lifting plate 500 can also be driven to move up and down.

[0065] The pneumatic clamping assembly 400 is mounted on the mounting seat 300 and is used to clamp the lifting head and the inner pull rod 120 and to drive the inner pull rod 120 to move up and down so that the supporting claws 220 on the bobbin yarn supporting mechanism can be switched between an expanded state and a retracted state.

[0066] like Fig. 9 As shown, the pneumatic clamping assembly 400 includes a pneumatic finger and two auxiliary clamping fingers 430. Like the conventional pneumatic finger, the pneumatic finger of this embodiment is composed of a finger cylinder 410 and two clamping fingers 420 respectively arranged on the finger cylinder 410. The finger cylinder 410 can drive the two clamping fingers 420 to open and close, so that the two clamping fingers 420 can clamp the clamped object. The two auxiliary clamping fingers 430 are respectively arranged on the two clamping fingers 420, that is, one auxiliary clamping finger 430 is arranged on one of the clamping fingers 420, and the other auxiliary clamping finger 430 is arranged on the other clamping finger 420. The auxiliary clamping fingers 430 and the clamping fingers 420 are connected in a sliding fit, so that the two auxiliary clamping fingers 430 can move up and down respectively relative to the two clamping fingers 420. In addition, the two auxiliary clamping fingers 430 are respectively connected to the lifting plate 500. When the lifting plate 500 is raised or lowered, the two auxiliary clamping fingers 430 can be driven to move up and down respectively relative to the two clamping fingers 420. Specifically, an adjustment slot 510 is provided on the lifting plate 500, and the upper ends of the two auxiliary clamping fingers 430 pass upward through the adjustment slot 510 and then hang on the lifting plate 500. By providing the adjustment slot 510, the two auxiliary clamping fingers 430 can move along the adjustment slot 510, so that the two auxiliary clamping fingers 430 can open and close together with the two clamping fingers 420.

[0067] In addition, the two clamping fingers 420 are provided with second clamping parts 421 for clamping the second clamped part 131 on the pulling head 130. When the two clamping fingers 420 are close to each other for clamping, the second clamping parts 421 on the two clamping fingers 420 jointly clamp the second clamped part 131. The two auxiliary clamping fingers 430 are provided with first clamping parts 431 for clamping the first clamped part 123. When the two auxiliary clamping fingers 430 are close to each other for clamping, the first clamping parts 431 on the two auxiliary clamping fingers 430 jointly clamp the first clamped part 123 on the inner pull rod 120.

[0068] The shapes of the first clamping portion 431 and the second clamping portion 421 can be set according to the shapes of the first clamped portion 123 and the second clamped portion 131. For example, when the first clamped portion 123 and the second clamped portion 131 are spherical, the first clamping portion 431 and the second clamping portion 421 are spherical concave cavities that match the spherical surface; when the first clamped portion 123 and the second clamped portion 131 are plate-shaped, the first clamping portion 431 and the second clamping portion 421 are concave cavities that match the plate-shaped; when the first clamped portion 123 and the second clamped portion 131 are grooves, the first clamping portion 431 and the second clamping portion 421 are protrusions that match the grooves. Of course, the shapes of the first clamped portion 123 and the second clamped portion 131 can be different. In this case, the first clamping portion 431 and the second clamping portion 421 are shapes that match the first clamped portion 123 and the second clamped portion 131, respectively.

[0069] As an optional implementation, Fig. 9 As shown, a mounting plate 450 is provided at the lower end of the pneumatic finger, and a guide bowl 440 is provided at the lower end of the mounting plate 450. The guide bowl 440 is in the shape of an inverted funnel as a whole, and has an opening at its upper end. The mounting plate 450 also has an opening. The interior of the guide bowl 440 is connected to the clamping cavity formed between the two clamping fingers 420 through the opening. In this way, the guide bowl 440 can guide the upper end of the lifting rod assembly 100 to the clamping cavity between the two clamping fingers 420.

[0070] When in use, the entire pneumatic clamp is installed on an external robotic arm and moved by the robotic arm. After placing a number of bobbins on the bobbin yarn support mechanism, the robotic arm moves the pneumatic clamp to the top of the bobbin yarn support mechanism, aligns the guide bowl 440 with the bobbin yarn support mechanism, and then lowers the pneumatic clamp. Under the guidance of the guide bowl 400, the lifting head 130 of the bobbin yarn support mechanism enters between the two clamping fingers 420, and the upper end of the inner pull rod 120 enters between the two auxiliary clamping fingers 430. The finger cylinder 410 drives the two clamping fingers 420 to approach each other. At this time, the two clamping fingers 420 clamp the lifting head 130, and the two auxiliary clamping fingers 430 clamp the upper end of the inner pull rod 120. Fig.10 As shown, the robot arm moves the package yarn support mechanism and puts the package yarn support mechanism into the storage barrel of the dehydrator. Finally, the two clamping fingers 420 and the two auxiliary clamping fingers 430 release the package yarn support mechanism to complete the material discharge. After the dehydration is completed, the above steps are repeated, and the pneumatic clamp clamps the package yarn support mechanism again and moves it to the unloading area. The lifting cylinder 700 moves to make the lifting plate 500 rise, so as to drive the two auxiliary clamping fingers 430 to move upward, thereby pulling the inner pull rod 120 upward, and the support claw 220 enters the contracted state, and the package yarn falls from the package yarn support mechanism to complete the material collection.

[0071] In specific use, the material taking and releasing device can also be used only for the material taking process, that is, before dehydration, the bobbin yarn supporting mechanism is manually placed into the material storage barrel of the dehydrator, and then multiple bobbins of yarn are manually loaded onto the bobbin yarn supporting mechanism in the material storage barrel. After dehydration is completed, the material can be taken according to the above-mentioned material taking steps.

[0072] The pneumatic clamp of this embodiment can be installed on an external robot arm to realize automated production operations, further improve production efficiency and reduce labor costs.

[0073] Example 3

[0074] This embodiment is basically the same as the embodiment 2, except that the material taking and placing device in this embodiment includes a plurality of the bobbin yarn supporting mechanisms in the embodiment 1, and the pneumatic clamp is provided with pneumatic clamping assemblies 400 whose number matches the bobbin yarn supporting mechanisms. For example, the number of bobbin yarn supporting mechanisms can be set to two, three, four or more, and the pneumatic clamping assemblies 400 on the pneumatic clamp are set to match the number of bobbin yarn supporting mechanisms.

[0075] In addition, when the number of the pneumatic clamping assemblies 400 is set to be multiple, the distribution position of the pneumatic clamping assemblies 400 on the mounting seat 300 matches the distribution of the storage barrels 1100 on the dehydrator 1000. For example, when the storage barrels 1100 on the dehydrator 1000 are distributed in a single-layer annular shape, multiple pneumatic clamping assemblies 400 are also distributed in a circular arc shape on the mounting seat 300 to match the single-layer annular distribution of the storage barrels 1100. In this way, a plurality of bobbin yarn support mechanisms loaded with barrel-ratio yarns can be placed in the plurality of storage barrels 1100 of the dehydrator 1000 respectively by using one pneumatic clamp, or the bobbin yarn support mechanisms loaded with barrel-ratio yarns in the plurality of storage barrels 1100 can be taken out. For another example, the storage barrels 1100 of some dehydrators 1000 are distributed in a double-layer annular shape, and are distributed in a triangle between two adjacent storage barrels 1100 located in the outer ring and a storage barrel 1100 of a certain inner ring, such as Fig.12 As shown, at this time, the pneumatic clamping assembly 400 on the pneumatic clamp can be set to three, and the distribution method is also a corresponding triangular distribution, such as Fig.11 As shown, three pneumatic clamping assemblies 400 can cooperate with two outer storage barrels and one inner storage barrel distributed in a triangle.

[0076] In addition, if Figure 8As shown, a movable slot hole 310 can be set on the mounting seat 300. During installation, the pneumatic clamping assembly 400 can be installed on the mounting seat 300 after a screw is passed through the movable slot hole 310. The setting of the movable slot hole 310 can adjust the installation position of the pneumatic clamping assembly 400, so that the installation positions of multiple pneumatic clamping assemblies 400 can better match the distribution positions of the storage barrels 1100 of the dehydrator 1000.

[0077] The pneumatic clamp of this embodiment can be provided with multiple pneumatic clamping components to cooperate with the storage barrels distributed on the dehydrator, so that multiple bobbin yarn support mechanisms with bobbin yarns can be placed in or out of multiple storage barrels of the dehydrator at one time, which greatly improves the taking and placing efficiency.

[0078] Example 4

[0079] This embodiment provides another material taking and placing device, which includes the bobbin yarn supporting mechanism in the above-mentioned embodiment 1, and a manual clamp matched with the bobbin yarn supporting mechanism.

[0080] like Fig.13 As shown, the manual clamp includes a manual clamping structure 800 and a lifting clamping structure 900 which is movable up and down and is disposed on the manual clamping structure 800 .

[0081] Among them, Fig.14 As shown, the manual clamping structure 800 includes two manual clamping members 810 swingably connected together via a connecting plate 820, and an annular spring 830 sleeved on the two manual clamping members 810 for clamping the two manual clamping members 810 together.

[0082] Specifically, Fig.15 As shown, the manual clamping member 810 includes a clamping handle 811 and a clamping flap 812 connected to the lower end of the clamping handle 811. A rotating shaft is respectively provided at both ends of the connecting plate 820, and the clamping handles 811 of the two manual clamping members 810 are respectively installed on the two rotating shafts near the middle position, so that the two manual clamping members 810 can swing with the two rotating shafts as fulcrums respectively. The outer walls of the clamping flaps 812 of the two manual clamping members 810 are both provided with an annular mounting groove 814, and the annular spring 830 is stuck in the annular mounting groove 814 of the two clamping flaps 812. The two clamping flaps 812 are clamped together by the pulling force of the annular spring 830, as shown in FIG. Fig.13 shown.

[0083] In addition, the two clamping petals 812 are both semicircular, and when the two clamping petals 812 are clamped together, an inverted funnel-shaped structure is formed, and the upper end of the inverted funnel-shaped structure is open. The inner sides of the two clamping petals 812 are respectively provided with third clamping portions 813, and when the two clamping petals 812 are clamped together, the third clamping portions 813 on the two clamping petals 812 can clamp the second clamped portion 131 on the lifting head 130. Similarly, as described in Example 2, the shape of the third clamping portion 813 also matches the shape of the second clamped portion 131, which will not be described here.

[0084] like Fig.16 As shown, the lifting and clamping structure 900 includes a lifting handle 910 disposed on any of the manual clamping members 810 and movable up and down through a limiting column 920, and a reset spring 930 sleeved on the limiting column 920 for providing a downward thrust to the lifting handle 910. Specifically, the lower end of the limiting column 920 passes through the bottom plate of the lifting handle 910 and is connected to the manual clamping member 810, and there is a clearance fit between the limiting column 920 and the lifting handle 910, so that the lifting handle 910 can move up and down relative to the limiting column 920. The upper end of the limiting column 920 is a limiting head, the diameter of the limiting head is larger than the diameter of the column, and the reset spring 930 is located between the limiting head and the bottom plate of the lifting handle 910. When the lifting handle 910 is lifted up, the reset spring 930 is compressed. When the lifting force on the lifting handle 910 disappears, the lifting handle 910 moves downward and resets under the action of the reset spring 930.

[0085] In addition, vertically distributed waist-shaped holes 911 can be set on the lifting handle 910, and a pin shaft 820 is set on the connecting plate 820. The pin shaft 820 is inserted into the waist-shaped hole 911. When the lifting handle 910 moves up and down, the pin shaft 820 moves along the waist-shaped hole 911. The cooperation between the pin shaft 820 and the waist-shaped hole 911 can make the lifting handle 910 move up and down more smoothly, preventing the lifting handle 910 from swinging.

[0086] A fourth clamping portion 912 for clamping the first clamped portion 123 is disposed at the bottom of the lifting handle 910 . Similarly, the shape of the fourth clamping portion 912 matches that of the first clamped portion 123 .

[0087] Through the above structure, when the bobbin yarn support mechanism needs to be clamped, the two clamping handles 811 are squeezed by hand to make the two clamping handles 811 swing and approach each other, and the two clamping petals 812 are away from each other (i.e. open), and the two clamping petals 812 are put on the upper end of the bobbin yarn support mechanism. Since the two clamping petals 812 together form an inverted funnel-shaped structure, the upper end of the bobbin yarn support mechanism can smoothly pass through the upper end opening of the funnel-shaped structure. Then, the two clamping handles 811 are released, and under the action of the annular spring 830, the two clamping petals 812 are closed again, and at this time, the third clamping part 813 clamps the second clamped part 131 on the lifting head 130, and the fourth clamping part 912 clamps the first clamped part 123 on the inner pull rod 120, so that the entire bobbin yarn support mechanism can be lifted. When the bobbin yarn on the bobbin yarn supporting mechanism needs to be unloaded, the lifting handle 910 is pulled upward by fingers, the inner pull rod 120 is pulled upward, the supporting claw 220 on the bobbin yarn supporting mechanism enters a retracted state, and the bobbin yarn falls from the bobbin yarn supporting mechanism, completing the unloading.

[0088] In this embodiment, the support claw 220 can be controlled to expand or contract by a manual clamp, so that the bobbin yarn on the bobbin yarn supporting mechanism can be unloaded quickly and conveniently, further improving the working efficiency.

[0089] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
