Description

Technical Field

[0001] This application relates to the field of clamping technology, and in particular to coil loading and unloading equipment. Background Technology

[0002] When processing sheet materials such as fabrics and plastic films, they are usually rolled up so that they can be processed or transported in rolls. When transferring the rolled material for storage or use, it is usually necessary to clamp the roll.

[0003] Currently, most clamps hold the coiled material by placing the chuck around its outer perimeter. When the coiled material is soft, if the clamping force is too large, the material may be damaged, causing unnecessary losses and increasing production costs. If the clamping force is too small, the friction between the coiled material and the chuck will be too small, which may cause the coiled material to fall off, making subsequent transfer operations difficult. Utility Model Content

[0005] Mounting rack;

[0006] The pick-and-place mechanism includes:

[0007] An inner clamping member includes at least two inner clamping bodies and an inner clamping drive assembly, the inner clamping drive assembly being mounted on the mounting frame, at least two of the inner clamping bodies being mounted on the inner clamping drive assembly and being driven by the inner clamping drive assembly to at least partially approach or move away from each other, and at least two of the inner clamping bodies being driven to at least partially move away from each other when placed in the insert shaft hole of the roll spool to apply pressure to the inner wall of the insert shaft hole;

[0008] An outer clamping member includes at least two outer clamping bodies and an outer clamping drive assembly. The outer clamping drive assembly is mounted on the mounting frame. At least two of the outer clamping bodies are distributed around the outer periphery of all the inner clamping bodies. At least two of the outer clamping bodies are mounted on the outer clamping drive assembly and driven by the outer clamping drive assembly to at least partially approach or move away from each other. At least two of the outer clamping bodies are driven to at least partially approach each other when they are placed around the outer periphery of the roll to apply pressure to the outer wall of the roll.

[0009] According to one embodiment of this application, at least two of the outer clamping bodies are driven to approach or move away from each other, each forming an arc wall. When at least two of the outer clamping bodies are driven to approach each other at least partially around the outer periphery of the roll to clamp the roll, the arc wall abuts against the peripheral wall of the roll, and the curvature of the arc wall matches the curvature of the peripheral wall of the roll.

[0010] According to one embodiment of this application, at least two of the inner clamping bodies are driven to move closer or further apart from each other, and each of the portions forms an anti-slip structure. When at least two of the inner clamping bodies are driven to move at least partially apart from each other within the insertion shaft hole to clamp the roll material within the insertion shaft hole, the anti-slip structure abuts against the inner wall of the insertion shaft hole.

The inner clamp body is pivotally connected to the mounting member. The anti-slip structure is formed at one end of the inner clamp body away from its axis of rotation. The two ends of each connector are pivotally connected to an inner clamp body and an inner clamp drive member, respectively. The position of the connector connected to the inner clamp body is different from the position of the inner clamp body connected to the mounting member. The inner clamp drive member is configured to extend and retract to push and pull multiple inner clamp bodies to rotate through the multiple connectors, so that the ends of the multiple inner clamp bodies with the anti-slip structure are closer to or further away from each other.

[0013] According to one embodiment of this application, the inner clamp body is rotated so that one end of the inner clamp body with the anti-slip structure is turned into or out of the side through hole. When the end of the inner clamp body with the anti-slip structure is turned into the side through hole, the mounting member is inserted into the insertion shaft hole in such a way that the inner clamp body is placed in the side through hole.

[0014] According to one embodiment of this application, the mounting frame includes a frame body and at least two sets of guide members. Each guide member includes a guide body and a guide structure. The size of the guide body is adapted to the size of the guide structure. In each set of guide members, either the guide body or the guide structure is disposed on the frame body and the other is disposed on an outer clamping body. When at least two outer clamping bodies are close to or far from each other, each outer clamping body slides on the frame body through the cooperation of the guide body and the guide structure.

[0023] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0024] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] refer to Figures 1 to 5 A preferred embodiment of the roll material handling device according to this application will be described in detail below. The roll material handling device includes a mounting frame 10 and a handling mechanism 20. The handling mechanism 20 is mounted on the mounting frame 10 and is used to grip the roll material for subsequent transfer of the roll material.

[0027] The pick-and-place mechanism 20 includes an inner clamping member 21, which comprises at least two inner clamping bodies 211 and an inner clamping drive assembly 212. The inner clamping drive assembly 212 is mounted on the mounting bracket 10. At least two of the inner clamping bodies 211 are mounted on the inner clamping drive assembly 212 and driven by the inner clamping drive assembly 212 to at least partially move closer to or further away from each other. When the at least two inner clamping bodies 211 are placed within the insert shaft hole of the roll, they are driven to at least partially move away from each other to apply pressure to the inner wall of the insert shaft hole, thereby clamping the roll from within.

[0028] The pick-and-place mechanism 20 further includes an outer clamping member 22, which comprises at least two outer clamping bodies 221 and an outer clamping drive assembly 222. The outer clamping drive assembly 222 is mounted on the mounting frame 10. At least two outer clamping bodies 221 are distributed around the outer periphery of all the inner clamping bodies 211. At least two outer clamping bodies 221 are mounted on the outer clamping drive assembly 222 and driven by the outer clamping drive assembly 222 to at least partially approach or move away from each other. When the at least two outer clamping bodies 221 are placed around the outer periphery of the roll, they are driven to at least partially approach each other to apply pressure to the outer wall of the roll, thereby clamping the roll from the outside.

[0029] In this way, the inner clamping member 21 and the outer clamping member 22 work together to clamp the coil material from both inside and outside, thereby increasing the contact surface of the coil material when it is clamped, thus improving the firmness and stability of the clamping. Moreover, when the material of the coil material is a soft material, the internal clamping is taken into account, which effectively avoids the situation of falling off due to insufficient clamping force or damaging the material due to excessive clamping force compared to the method of clamping only from the outside.

[0030] It is worth mentioning that the degree to which at least two inner clamping bodies 211 are at least partially far apart from each other and the degree to which at least two outer clamping bodies 221 are at least partially close to each other can be adjusted to meet the requirements of clamping rolls of different sizes, thus achieving high versatility.

[0031] Furthermore, the portions of at least two inner clamping bodies 211 that are driven to move closer or further apart each form an anti-slip structure 2111. When at least two inner clamping bodies 211 are driven to move at least partially apart within the insert shaft hole to clamp the roll material within the insert shaft hole, the anti-slip structure 2111 abuts against the inner wall of the insert shaft hole to increase the friction between the inner clamping body 211 and the inner wall of the insert shaft hole, effectively preventing the roll material from slipping and ensuring that the roll material is firmly clamped.

[0032] Preferably, the anti-slip structure 2111 is implemented as a plurality of spaced protrusions formed on the surface of the inner clamping body 211, and the length direction of each of the protrusions is different from the axial direction of the insertion shaft hole, so as to increase the resistance of the roll material moving relative to the inner clamping body 211 and separating from it, and improve the anti-slip performance during clamping.

[0033] In one embodiment, the anti-slip structure 2111 is implemented as a plurality of spaced protrusions formed on the surface of the inner clamping body 211.

[0034] Preferably, the portions of at least two of the outer clamping bodies 221 that are driven to approach or move away from each other each form an arcuate wall 2211. When the at least two outer clamping bodies 221 are driven to at least partially approach each other around the outer periphery of the roll to clamp the roll, the arcuate wall 2211 abuts against the peripheral wall of the roll. The curvature of the arcuate wall 2211 is adapted to the curvature of the peripheral wall of the roll to maximize the contact area of ​​the external clamping and ensure a firm clamping.

[0035] In one embodiment, the inner clamp drive assembly 212 is implemented to include at least two cylinders, each inner clamp body 211 is mounted on one of the cylinders, and at least two inner clamp bodies 211 are each driven by the corresponding cylinder to move as a whole to move closer to or further away from each other in order to perform a clamping operation within the insert shaft hole.

[0036] Preferably, the inner clamp drive assembly 212 includes a mounting member 2121, at least two connectors 2122, and an inner clamp drive member 2123. The inner clamp body 211 is pivotally connected to the mounting member 2121, and the anti-slip structure 2111 is formed at one end of the inner clamp body 211 away from its axis of rotation. Each connector 2122 is pivotally connected at both ends to one inner clamp body 211 and one inner clamp drive member 2123, respectively, and the position of the connector 2122 connected to the inner clamp body 211 is different from the position of the inner clamp body 211 connected to the mounting member 2121. The inner clamp drive member 2123 is configured to extend and retract to push and pull multiple inner clamp bodies 211 to rotate via the multiple connectors 2122, so that the ends of the multiple inner clamp bodies 211 with the anti-slip structure 2111 move closer or further apart to perform clamping operations within the insertion shaft hole.

[0037] Preferably, the inner clamping drive 2123 is implemented as a cylinder.

[0038] Furthermore, the mounting member 2121 has a mounting hole 212101, and the mounting member 2121 forms at least two side through holes 212102 that penetrate the peripheral wall of the mounting hole 212101 to communicate the mounting hole 212101 with the outside. The inner clamp body 211 is at least partially placed in the side through holes 212102, and one end of the inner clamp drive member 2123 connected to the connecting member 2122 is placed in the mounting hole 212101. In this way, the inner clamp drive member 2123 extends and retracts within the mounting hole 212101, which increases the overall aesthetics without affecting the rotation of the inner clamp body 211.

[0039] Preferably, the inner clamping body 211 rotates so that one end of the inner clamping body 2111 with the anti-slip structure 2111 rotates into or out of the side through hole 212102. When the end of the inner clamping body 211 with the anti-slip structure 2111 rotates into the side through hole 212102, the mounting member 2121 is inserted into the insertion shaft hole in such a way that the inner clamping body 211 is retracted into the side through hole 212102. In this way, inserting the mounting member 2121 into the insertion shaft hole allows all the inner clamping bodies 211 to be installed into the insertion shaft hole, achieving quick insertion. Furthermore, the insertion shaft hole only needs to be slightly larger than the size of the mounting member 2121, reducing the size requirements of the insertion shaft hole and increasing the convenience of operation.

[0040] Preferably, the inner clamping body 211 has six parts, and the number of side through holes 212102 and the number of connecting members 2122 are the same as the number of inner clamping bodies 211. The six side through holes 212102 are divided into two groups, and the two groups of side through holes 212102 are spaced apart along the length of the mounting member 2121, so that the two groups of inner clamping bodies 211 can apply force to the inner wall of the insertion shaft hole at different positions in the axial direction of the mounting hole 212101, so that the coiled material is firmly clamped. In addition, the three side through holes 212102 in one group are equally spaced on the outer periphery of a radial section of the mounting hole 212101, so that the three inner clamping bodies 211 in one group can apply force to the coiled material in multiple directions within the insertion shaft hole, further improving the firmness of the coiled material clamping.

[0041] Preferably, at least two of the outer clamp bodies 221 are each driven by the outer clamp drive assembly 222 to move as a whole to move closer to or further away from each other in order to perform clamping operations on the outer periphery of the roll.

[0042] Preferably, the external clamp drive assembly 222 is implemented to include at least two cylinders, each of the external clamp bodies 221 being mounted on one of the cylinders to be driven to move by the corresponding cylinder.

[0043] Furthermore, the mounting bracket 10 includes a main body 11 and at least two sets of guide members 12. Each guide member 12 includes a guide body 121 and a guide structure 122, the dimensions of which are adapted to the dimensions of the guide structure 122. In each set of guide members 12, either the guide body 121 or the guide structure 122 is disposed on the main body 11, while the other is disposed on an outer clamping body 221. When at least two outer clamping bodies 221 move closer or further apart, each outer clamping body 221 slides on the main body 11 through the cooperation of the guide body 121 and the guide structure 122, thereby increasing the stability of the movement of the outer clamping body 221.

[0044] Preferably, each group of guide members 12 is provided with two, and the guide bodies 121 or guide structures 122 of the two guide members 12 in each outer clamp body 221 are spaced apart, so that the two guide members 12 in a group cooperate to guide the outer clamp body 221 to ensure stable movement.

[0045] Preferably, the guide body 121 is mounted on the outer clamping body 221, and the guide structure 122 is formed on the frame body 11. The guide body 121, which is disposed on the outer clamping body 221, slides on the guide structure 122 to guide the outer clamping body 221.

[0046] Preferably, the guide body 121 is implemented as a plug, and the guide structure 122 is implemented as a socket.

[0047] Furthermore, the frame body 11 is supported and is mounted on a crane and can be moved by external force so as to transfer the clamped coil by pulling the mounting frame 10.

[0048] Furthermore, the mounting frame 10 includes a rotating seat 13, which is rotatably mounted on the frame body 11. The pick-and-place mechanism 20 is mounted on the rotating seat 13 and rotates together with the rotating seat 13 to adjust the posture, thereby adjusting the posture of the clamped coil.

[0049] refer to Figures 1 to 5 The roll material handling device further includes a posture adjustment mechanism 30, which is installed on the frame body 11. The rotating seat 13 is connected to the posture adjustment mechanism 30 and is driven by the posture adjustment mechanism 30 to rotate, so as to automatically adjust the posture of the clamped roll material.

[0050] Preferably, the posture adjustment mechanism 30 is implemented as a cylinder, the cylinder body is pivotally connected to the frame body 11, the cylinder rod is pivotally connected to one end of the rotating seat 13, and the pick-and-place mechanism 20 is installed at one end of the rotating seat 13 away from the cylinder rod. The cylinder extends and retracts to push and pull the rotating seat 13 to rotate.

[0051] Preferably, two outer clamping bodies 221 are provided and arranged opposite to each other. The two outer clamping bodies 221 are driven to move towards or away from each other. The direction of movement of the outer clamping bodies 221 is parallel to the axis of rotation of the rotating seat 13, so that during the rotation of the rotating seat 13 driven by the attitude adjustment mechanism 30, the outer clamping bodies 221 are always kept outside the movement trajectory of the roll held by the pick-and-place mechanism 20, so that when the rotating seat 13 rotates 90 degrees to adjust the roll from a vertical to a horizontal position, the outer clamping bodies 221 will not interfere with the area for horizontally placing the roll.

[0052] Preferably, the frame body 11 is vertically arranged, the rotating seat 13 is rotatably mounted on the lower end of the frame body 11, and the guide body 121 or the guide structure 122 is disposed on the frame body 11. When the coil is clamped in a manner that keeps it vertical in its axial direction, the coil is located below the mounting frame 10; when the coil is clamped in a manner that keeps it horizontal in its axial direction, the coil is located on one side of the mounting frame 10.

[0053] Furthermore, the frame body 11 includes a frame portion 111 and at least one gripping portion 112. The frame portion 111 is mounted on the trolley, the rotating seat 13 is rotatably mounted on the frame portion 111, and the gripping portion 112 is mounted on the frame portion 111. The gripping portion 112 is held and applies force to the frame portion 111 mounted on the trolley to pull it forward. The gripping portion 112 and the coiled material that is clamped and axially kept horizontal are located on both sides of the frame portion 111 to facilitate loading and unloading operations.

[0054] Preferably, there are two gripping parts 112, and the two gripping parts 112 are spaced apart so that the staff can hold them with both hands to perform picking and placing operations.

[0055] Furthermore, the mounting frame 10 also includes a mounting accessory 14, which includes a plurality of mounting holes 141 formed at the high end of the frame body 111. The frame body 111 is hooked to the trolley through the mounting holes 141. The plurality of mounting holes 141 are arranged at intervals and their arrangement direction is parallel to the axial direction of the coil material that is clamped and kept horizontal.

[0056] In this way, when picking up and placing rolls of material of different sizes, the center of gravity of the roll picking and placing device can be adjusted by adjusting the position of the trolley connected to the frame 111. Compared with a fixed connection position, this effectively avoids the situation where the center of gravity shifts excessively and makes it difficult to adjust the roll to a horizontal position after it has been clamped and kept vertical. In other words, because the center of gravity of the roll picking and placing device is adjusted, the roll is automatically adjusted to a horizontal position according to a predetermined rotation angle after being clamped, without the need to apply force to the frame 111 to adjust the whole, making operation less labor-intensive and easier to control the overall movement.

[0057] Preferably, the assembly 14 further includes an assembly body 142, which is detachably snapped into an assembly hole 141 and is used for connection with the overhead crane. By assembling the assembly body 142 into the assembly hole 141 at different positions, the position of the overhead crane connected to the frame portion 111 can be changed.

[0058] Furthermore, when the inner clamping drive 2123 is implemented as a cylinder, and the outer clamping drive assembly 222 is implemented including at least two cylinders, and the attitude adjustment mechanism 30 is implemented as a cylinder, each cylinder is connected to an electromagnetic reversing valve via a pipeline. The electromagnetic reversing valve switches the fluid flow direction to control the extension and retraction of the cylinder. The roll material handling equipment also includes a control assembly 40, and the electromagnetic reversing valve is controllably connected to the control assembly 40 to automatically perform handling and placement operations.

[0059] Preferably, the control component 40 includes a plurality of push-button switches mounted on the grip 112, and each push-button switch is electrically connected to a solenoid directional valve. Thus, when the operator holds the grip 112, pressing the push-button switch controls the corresponding solenoid directional valve, thereby controlling the extension or retraction of the corresponding cylinder, ultimately achieving clamping and placement operations and posture adjustment operations.
