Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing, and specifically to a fabric reel grasping and lifting mechanism. Background Art

[0002] A fabric reel is a component widely used in the textile industry, usually a cylindrical structure made of metal or plastic, used to collect, store, and transport fabrics in a coiled form.

[0003] When mass-producing fabrics, a relatively large number of fabric reels are required to collect products. Therefore, some manufacturers use relevant mechanisms to execute work instructions on fabric reels, including grasping, lifting, transferring, etc., to reduce the labor intensity of workers.

[0004] After retrieval, Chinese Patent (Publication No.: CN107265192B) discloses a working method of an automatic fabric reel grasping and lifting mechanism. The patent includes a frame. The bottom surfaces of the left and right crossbeams of the frame are provided with conveying screws. The two ends of the conveying screws are respectively hinged on corresponding support blocks. The support blocks are fixed on the bottom surfaces of the crossbeams. A driving servo motor is fixed on the top surface of the crossbeam. A driving wheel is fixed on the output shaft of the driving servo motor. One end of the conveying screw extends out of the support block and is fixed with a transmission wheel. A belt is tensioned between the driving wheel and the transmission wheel. A moving block is screwed on the conveying screw. A limiting block is fixed on the upper part of the moving block. The top surface of the limiting block has a groove. The bottom of the crossbeam is inserted into the groove. A lifting cylinder is fixed on the bottom surface of the limiting block. The push rod of the lifting cylinder is vertically downward. A clamping fixing plate is fixed on the push rod of the lifting cylinder.

[0005] In the prior art, when grasping and lifting a fabric reel, it is necessary to maintain good firmness between the relevant mechanism and the fabric reel to avoid the problem of separation between the fabric reel and the mechanism during transfer. And when the mechanism assembles the fabric reel, it is necessary to avoid damaging the fabric reel and the products outside it. Therefore, the present invention proposes a fabric reel grasping and lifting mechanism. Summary of the Invention

[0006] The purpose of the present invention is to provide a fabric reel grasping and lifting mechanism.

[0007] The technical problem solved by the present invention is: how to improve the firmness of the mechanism during the assembly of the fabric reel;

[0008] When the mechanism assembles the fabric reel, how to avoid damaging it.

[0009] The present invention can be implemented through the following technical solutions: A fabric reel grasping and lifting mechanism includes a driving frame, a connection component is installed at the output end of the driving frame, a connection frame is installed at the output end of the connection component, at least one set of first stroke mechanisms is installed on the lower side of the connection frame, a second stroke mechanism is installed at the bottom end of the first stroke mechanism, and connecting plates are installed at both ends of the second stroke mechanism;

[0010] Horizontal driving mechanisms are installed on both sides of the two connecting plates, and bottom support components are installed between the sides of the two connecting plates and the corresponding horizontal driving mechanisms. After starting, the two bottom support components form a sunken area inside under the drive of the horizontal driving mechanisms;

[0011] When the two bottom support components support the fabric reel, the sunken areas of the two bottom support components are in contact with the fabric reel;

[0012] Steering mechanisms are installed on the sides of the two connecting plates, and clamping components are installed at the output ends of the two steering mechanisms;

[0013] The two clamping components are arranged in a staggered manner with their adjacent bottom support components, and the two clamping components rotate to the upper side of the fabric reel under the drive of the corresponding steering mechanisms, and cooperate with the two bottom support components to grasp the fabric reel.

[0014] A further technical improvement of the present invention lies in that: the connection component includes a connection sleeve for connecting with the driving frame, a lifting cylinder is installed at the bottom end of the connection sleeve, the output end of the lifting cylinder faces downward, and a steering motor is installed;

[0015] The two connecting plates move in the vertical direction based on the lifting cylinder and rotate in the horizontal direction through the steering motor to adjust the grasping angle.

[0016] A further technical improvement of the present invention lies in that: the bottom support component includes two side frame bars, the opposite ends of the two side frame bars are respectively rotatably connected to the corresponding connecting plate and the output end of the corresponding horizontal driving mechanism;

[0017] The opposite ends of the two side frame bars both tilt upward, and a receiving bar is rotatably connected between the upward-tilted ends of the two side frame bars;

[0018] The receiving bar is sunken downward;

[0019] One side frame bar connected to the horizontal driving mechanism moves towards the direction of the other side frame bar under the drive of the horizontal driving mechanism, and when moving, the upward-tilted ends of the two side frame bars continue to tilt upward, so as to further sink the sunken part of the receiving bar downward to form a sunken area.

[0020] A further technical improvement of the present invention lies in that: the clamping component includes a lifting frame connected to the corresponding steering mechanism, and a side bending frame is installed at the output end of the lifting frame, and the side bending frame is hook-shaped;

[0021] When the side bending frame rotates based on the steering mechanism, its position is adjusted by the lifting frame to avoid contact with the second stroke mechanism.

[0022] A further technical improvement of the present invention lies in that: a plurality of rollers are rotatably connected inside the clamping component, and the rotation direction of each roller is parallel to the connecting plate.

[0023] A further technical improvement of the present invention lies in that: two groups of limiting blocks are installed on the sides of the two groups of connecting plates below the bottom support component;

[0024] The two groups of limiting blocks are respectively arranged below the two side frame bars in the corresponding bottom support component. After the bottom support component is unfolded based on the corresponding horizontal driving mechanism, the two groups of limiting blocks respectively limit the angles of the two side frame bars, thereby facilitating the subsequent bending of the receiving strip.

[0025] A further technical improvement of the present invention lies in that: receiving grooves are opened on the sides of the two groups of connecting plates above the bottom support component, and limiting members are installed inside the two groups of receiving grooves through reset members;

[0026] The two groups of limiting members both extend into the moving paths of the corresponding bottom support components, and the two groups of limiting members respectively correspond to the receiving strips in the two groups of bottom support components;

[0027] When the receiving strip rises based on the side frame bars on both sides of it, it contacts the corresponding limiting member, and with the assistance of the limiting member, it sinks downward. And after the limiting member contacts the receiving strip, it is driven by the receiving strip and rotates into the receiving groove through the reset member. And after the receiving strip moves to its upper side, it is reset from the receiving groove based on the reset member;

[0028] When the receiving strip descends, it contacts the limiting member, and also rotates it downward through the reset member until it is received in the receiving groove. And after the receiving strip moves to the lower side of the limiting member, the reset member resets the limiting member.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] Compared with the prior art, when the present invention grabs the fabric roll, it first supports the fabric roll from the lower side by the bottom support component, and both the side frame bars and the receiving strips in the bottom support component are made of elastic materials, which can reduce the damage to the fabric roll when the bottom support component moves and arches;

[0031] After the two groups of bottom support components support the fabric reel from its lower side, the two groups of clamping components inside reinforce it from the upper side of the fabric reel. And since the bottom support components are made of elastic material, after the clamping components come into contact with the fabric reel, the bottom support components can also play a buffering role, thereby protecting the fabric reel.

[0040] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, will detail the specific implementation manners, structures, features and their effects according to the present invention.

[0041] Please refer to Figures 1-4As shown in the figure, a fabric reel grasping and lifting mechanism includes a driving frame 1. The driving frame 1 is erected based on the site, and the relevant structures are selected according to the erection method. A connecting component 2 is installed at the output end of the driving frame 1. A connecting frame 3 is installed at the output end of the connecting component 2. Two groups of first stroke mechanisms 4 are installed on the lower side of the connecting frame 3. A second stroke mechanism 5 is installed at the bottom end of the first stroke mechanism 4. Connecting plates 6 are installed at both ends of the second stroke mechanism 5;

[0042] The second stroke mechanism 5 adopts a horizontal cylinder. The two connecting plates 6 are respectively connected to the fixed end and the output end of the horizontal cylinder. After the second stroke mechanism 5 is started, the distance between the two connecting plates 6 is adjusted;

[0043] One group of first stroke mechanisms 4 is fixedly connected to the fixed end of the second stroke mechanism 5, and the other group of first stroke mechanisms 4 is slidably connected to the output end of the second stroke mechanism 5;

[0044] Horizontal driving mechanisms 7 are installed on both sides of the two connecting plates 6, and bottom support components 8 are installed between the sides of the two connecting plates 6 and the corresponding horizontal driving mechanisms 7. After starting, the two bottom support components 8 drive by the horizontal driving mechanisms 7 form a sunken area inside;

[0045] When the two bottom support components 8 support the fabric reel, the sunken areas of the two bottom support components 8 are in contact with the fabric reel;

[0046] Steering mechanisms 9 are installed on the sides of the two connecting plates 6, and clamping components 10 are installed at the output ends of the two steering mechanisms 9;

[0047] In this embodiment, the horizontal driving mechanism 7 adopts a cylinder assembly, and the steering mechanism 9 adopts a motor assembly;

[0048] The two clamping components 10 and the adjacent bottom support components 8 are arranged in a staggered manner, and the two clamping components 10 are driven by the corresponding steering mechanisms 9 to rotate to the upper side of the fabric reel, and cooperate with the two bottom support components 8 to grasp the fabric reel.

[0049] Please refer to Figure 2 As shown in the figure, the connecting component 2 includes a connecting sleeve 21. The connecting sleeve 21 is used to connect with the driving frame 1. A lifting cylinder 22 is installed at the bottom end of the connecting sleeve 21. The output end of the lifting cylinder 22 faces downward and is equipped with a steering motor 23;

[0050] The two connecting plates 6 move in the vertical direction based on the lifting cylinder 22 and rotate in the horizontal direction through the steering motor 23 to adjust the grasping angle.

[0051] Please refer to Figures 3-4As shown in the figure, the bottom support assembly 8 includes two groups of side frame bars 81. The opposite ends of the two groups of side frame bars 81 are respectively rotatably connected to the corresponding connecting plates 6 and the output ends of the corresponding horizontal driving mechanisms 7;

[0052] The opposite ends of the two groups of side frame bars 81 are both upturned, and a receiving bar 82 is rotatably connected between the upturned ends of the two groups of side frame bars 81;

[0053] The receiving bar 82 is recessed downward;

[0054] One group of side frame bars 81 connected to the horizontal driving mechanism 7 moves in the direction of the other group of side frame bars 81 under the drive of the horizontal driving mechanism 7. And when moving, the upturned ends of the two groups of side frame bars 81 continue to upturn, so as to further recess the recessed part of the receiving bar 82 downward to form a recessed area.

[0055] Both the side frame bars 81 and the receiving bar 82 are made of rubber material, and the elastic strength of the side frame bars 81 is greater than that of the receiving bar 82.

[0056] The clamping assembly 10 includes a lifting frame 101 connected to the corresponding steering mechanism 9. The output end of the lifting frame 101 is equipped with a bending side frame 102, and the bending side frame 102 is hook-shaped;

[0057] When the bending side frame 102 rotates based on the steering mechanism 9, its position is adjusted through the lifting frame 101 to avoid contacting the second stroke mechanism 5.

[0058] A plurality of rollers are rotatably connected inside the clamping assembly 10, and the rotation directions of the rollers are all parallel to the connecting plate 6.

[0059] When the present invention is in use:

[0060] The connecting assembly 2 moves based on the driving frame 1, and through the lifting cylinder 22 and the steering motor 23 inside it, the two bottom support assemblies 8 are moved to the lower side of the fabric reel to be grabbed. Subsequently, the two horizontal driving mechanisms 7 are started, and one group of side frame bars 81 in the bottom support assembly 8 connected to them is moved, so as to cooperate with the side frame bars 81 in the other bottom support assembly 8 to recess the receiving bar 82 downward when lifting;

[0061] Subsequently, the lifting cylinder 22 lifts the two bottom support assemblies 8 upward, and the fabric reel is lifted by using the bottom support assemblies 8. Then the two steering mechanisms 9 are started, and the steering mechanisms 9 drive the clamping assembly 10 to rotate to the upper side of the fabric reel. When rotating, the lifting frame 101 in the clamping assembly 10 is started to change the position of the bending side frame 102, and then the fabric reel is fixed from the upper side through the bending side frame 102 to form the grasping of the fabric reel;

[0062] Finally, the driving frame 1 and the connecting assembly 2 are started to move the fabric reel.

[0063] Example 2

[0064] Please refer to Figures 5-6 As shown in the figure, a fabric reel grasping and lifting mechanism includes a driving frame 1. A connecting component 2 is installed at the output end of the driving frame 1. A connecting frame 3 is installed at the output end of the connecting component 2. A set of first stroke mechanisms 4 are installed on the lower side of the connecting frame 3. A second stroke mechanism 5 is installed at the bottom end of the first stroke mechanism 4. Connecting plates 6 are installed at both ends of the second stroke mechanism 5;

[0065] Horizontal driving mechanisms 7 are installed on both sides of the two groups of connecting plates 6, and bottom support components 8 are installed between the sides of the two groups of connecting plates 6 and the corresponding horizontal driving mechanisms 7. After starting, the two bottom support components 8 drive by the horizontal driving mechanisms 7 form a sunken area inside;

[0066] Steering mechanisms 9 are installed on the sides of the two groups of connecting plates 6. Clamping components 10 are installed at the output ends of the two groups of steering mechanisms 9;

[0067] The two clamping components 10 and the adjacent bottom support components 8 are arranged in a staggered manner, and the two clamping components 10 rotate to the upper side of the fabric reel under the drive of the corresponding steering mechanisms 9, and cooperate with the two bottom support components 8 to grasp the fabric reel.

[0068] The bottom support component 8 includes two side frame bars 81. The opposite ends of the two side frame bars 81 are respectively rotatably connected to the corresponding connecting plate 6 and the output end of the corresponding horizontal driving mechanism 7;

[0069] The opposite ends of the two side frame bars 81 both tilt upward, and a receiving bar 82 is rotatably connected between the upward-tilted ends of the two side frame bars 81;

[0070] Two groups of limiting blocks 11 are installed on the sides of the two groups of connecting plates 6 below the bottom support component 8;

[0071] The two groups of limiting blocks 11 are respectively arranged below the two side frame bars 81 in the corresponding bottom support component 8. After the bottom support component 8 expands based on the corresponding horizontal driving mechanism 7, the two groups of limiting blocks 11 respectively limit the angles of the two side frame bars 81, so as to facilitate the subsequent bending of the receiving bar 82.

[0072] Receiving grooves 12 are opened on the sides of the two groups of connecting plates 6 above the bottom support component 8. Restricting components 14 are installed in the two receiving grooves 12 through resetting components 13;

[0073] The two restricting components 14 both extend into the moving paths of the corresponding bottom support components 8, and the two restricting components 14 respectively correspond to the receiving bars 82 in the two bottom support components 8;

[0074] When the receiving bar 82 rises and depresses based on the side frame bars 81 on both of its sides, it contacts the corresponding limiting member 14, and with the assistance of the limiting member 14, it depresses downward. After the limiting member 14 contacts the receiving bar 82, it is driven by the receiving bar 82 and rotates into the receiving groove 12 through the reset member 13. And after the receiving bar 82 moves to its upper side, it resets from the receiving groove 12 based on the reset member 13;

[0075] In this embodiment, the reset member 13 includes a first elastic unit and a second elastic unit. The first elastic unit is arranged on the upper side of the limiting member 14 to limit the upward rotation tendency of the limiting member 14;

[0076] The second elastic unit is arranged on the lower side of the limiting member 14 to limit the downward rotation tendency of the limiting member 14;

[0077] And the elastic strength of the first elastic unit is greater than that of the second elastic unit. When the limiting member 14 is not subject to external force, the second elastic unit keeps the limiting member 14 inside the moving path of the corresponding bottom support assembly 8;

[0078] When the receiving bar 82 descends, it contacts the limiting member 14 and also rotates it downward through the reset member 13 until it is received in the receiving groove 12. And after the receiving bar 82 moves to the lower side of the limiting member 14, the reset member 13 resets the limiting member 14.
