Description

Technical Field

[0001] The present invention belongs to the technical field of wire cutting equipment, and in particular relates to a winding device and a wire cutting equipment. Background Art

[0002] At present, the winding wheel of the slicer has two conical surfaces at both ends, one end cooperates with the conical surface of the take-up and pay-off spindle, and the other end cooperates with the conical surface of the pressure cover. The pressure cover is fixed to the take-up and pay-off spindle by equal height screws. The rectangular spring inside the pressure cover is compressed, and the winding wheel is pressed against the conical surface of the take-up and pay-off spindle by elastic force; the coaxiality of the winding wheel and the take-up and pay-off spindle is ensured by the cooperation between the pressure cover and the take-up and pay-off spindle and the conical surfaces at both ends of the winding wheel. The pressing force of the rectangular spring provides an emergency stop torque through the static friction force between the matching conical surfaces of the winding wheel and the take-up and pay-off spindle.

[0003] However, when installing the winding reel with the above structure, the winding reel needs to be inserted into the reel-winding and rewinding main shaft, then the pressure cover is put on, and finally the equal height screws are screwed in and tightened manually with a torque wrench, which is a rather cumbersome operation; and the clearance between the pressure cover and the axial hole of the reel-winding and rewinding main shaft is small, which requires a high level of installation proficiency of the operator, resulting in low installation efficiency.

[0004] Therefore, the technical problem to be solved by this application is: how to realize the automation of the assembly of the wire wheel and the wire-reeling and wire-reeling spindle. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a winding device and wire cutting equipment to solve the problem that the prior art wire reel and the wire taking-up and paying-out spindle cannot be assembled automatically. The technical effect of the present application scheme is to realize the automation of the assembly of the wire reel and the wire taking-up and paying-out spindle.

[0006] The objectives of the present invention can be achieved through the following technical solutions: a winding device, comprising a reel; a shaft, a pressure-regulating pipeline is provided on the shaft, and a pressure-regulating hole is provided on the pressure-regulating pipeline for fluid to enter and exit; and a quick-change device, the quick-change device is arranged between the shaft and the reel, so that the shaft and the reel are detachably connected; wherein the quick-change device is connected to the pressure-regulating pipeline and has a locked state and an unlocked state, and can be switched to the locked state by the fluid in the pressure-regulating pipeline, or switched to the unlocked state by the back suction of the fluid in the pressure-regulating pipeline.

[0007] It can be understood that the shaft is used to connect with the wire wheel to drive the wire wheel to rotate, and the cutting line can be reeled in and out by setting a pressure regulating pipeline on the shaft to adjust the pressure difference. The fluid can enter and exit from the pressure regulating hole of the pressure regulating pipeline. The two states of the quick-change device can be switched by pushing or sucking the fluid, so that the shaft and the wire wheel can be locked and connected or unlocked and disassembled conveniently and quickly.

[0008] In the above-mentioned winding device, the quick-change device includes: a connecting seat connected to one end of the shaft body. An active rod is provided between the connecting seat and the shaft body, and one end of the active rod is connected to the pressure-regulating pipeline; a connecting sleeve detachably connected to the inside of the wire wheel and sleeved on the connecting seat; a locking structure provided between the active rod and the connecting sleeve. The locking structure has the above-mentioned locked state and unlocked state. In the locked state, the active rod and the connecting sleeve are radially abutted and locked. In the unlocked state, the active rod can axially move relative to the connecting sleeve under the action of the fluid in the pressure-regulating pipeline.

[0009] It can be understood that the connecting seat is connected to the shaft body, which can limit the excessive axial movement of the active rod and prevent it from detaching; the connecting sleeve is connected to the inside of the wire wheel and can form a locking structure with the axially moving active rod; the principle of the locking structure is to utilize the pressure difference change in the pressure-regulating pipeline in the shaft body to adjust the axial position of the active rod so that the active rod and the connecting sleeve are radially abutted and locked or axially move away from each other.

[0010] In the above-mentioned winding device, the locking structure includes: an elastic member disposed in the limiting hole on the connecting seat and sleeved on the groove on the active rod; a locking portion disposed on the connecting sleeve and located outside the elastic member; wherein, the elastic member can axially move along with the active rod and radially expand and extend out of the limiting hole to abut against the locking portion along the arc surface of the groove, or radially contract into the limiting hole to disengage from the locking portion along the arc surface of the groove.

[0011] It should be noted that the axial movement of the active rod is achieved by introducing fluid or sucking back fluid. When introducing fluid, the active rod is pushed by the fluid to move in the direction close to the connecting sleeve. Since the elastic member is limited by the limiting hole and cannot axially move synchronously with the active rod, it only radially contracts synchronously as the diameter of the groove at its sleeved position contracts. At this time, it is the unlocked state. When sucking back fluid, the active rod is pushed by the fluid to move in the direction away from the connecting sleeve, and the groove on the active rod moves synchronously, causing the elastic member to expand and bulge and abut against the protruding locking portion on the connecting sleeve, that is, the active rod and the connecting sleeve are locked and the assembly is completed. Similarly, when introducing fluid again, unlocking can be achieved.

[0012] In the above-mentioned winding device, it further includes: a fluid docking module disposed on one side of the shaft body opposite to it; a lifting mechanism disposed below the fluid docking module, which can drive the fluid docking module to lift to dock with or disengage from the pressure-regulating pipeline.

[0013] Understandably, the pressure-regulating pipeline on the shaft requires fluid to be introduced or removed. Manually docking the fluid source to the pressure-regulating pipeline is inefficient and cannot be automated. Therefore, a fluid docking module is provided to maintain a connection with the fluid source and dock with the pressure-regulating pipeline on the docking shaft as needed. The lifting mechanism automatically raises and lowers, delivering the fluid docking module to the shaft for docking, or automatically disengaging to retract the fluid docking module.

[0014] In the above-mentioned winding device, a quick docking structure is provided between the fluid docking module and the shaft body. The quick docking structure includes: an upper quick connector, which is arranged on the pressure regulating hole; and a lower quick connector, which is arranged on the docking hole of the fluid docking module. The upper quick connector can rotate with the shaft body in the axial direction of the lower quick connector, so that the cross-sectional projection of the upper quick connector and the cross-sectional projection of the lower quick connector substantially coincide with each other.

[0015] As you can understand, by providing an upper and lower quick connector, the pressure regulating hole and the docking hole can be quickly aligned and connected. When the shaft rotates, it can drive the upper quick connector to rotate synchronously. When the cross-sectional projection of the upper quick connector coincides with the cross-sectional projection of the lower quick connector, the alignment is complete and docking can be achieved by driving the lifting mechanism.

[0016] In the aforementioned winding device, the fluid docking module is further provided with a fluid docking tube for docking with a fluid source. It is understood that once docked with the fluid source, the fluid docking tube does not need to be disassembled, maintaining a continuous connection without interfering with the rotation of the upper shaft. For example, a valve may be provided within the fluid docking module to facilitate control over the on / off switching of fluid delivery.

[0017] The above-mentioned winding device further includes a driving device, wherein the driving device is disposed on one side of the shaft end, and the output end of the driving device is connected to the shaft end. For example, the output end of the driving device and the shaft end can be connected via a coupling, and when the output end of the driving device rotates, the shaft can be driven to rotate synchronously, and the rotation of the shaft can drive the connected reel to rotate synchronously to reel in and out the line.

[0018] The aforementioned winding device further includes a drive device, the drive device including a drive motor and an encoder, the encoder being capable of presetting the rotation angle of the drive motor to facilitate docking of the fluid docking module with the shaft. It is understood that the drive motor is controlled by the encoder, and when the reel and shaft need to be reassembled or disassembled, the encoder is required to control the drive motor to rotate to a set angle so that the docking hole on the fluid docking module and the pressure regulating hole on the shaft are directly opposite each other.

[0019] In the above-mentioned winding device, the lifting mechanism is a pneumatic cylinder, an electric cylinder or a hydraulic cylinder. Exemplarily, the lifting mechanism can be one of the pneumatic cylinder, the electric cylinder or the hydraulic cylinder to meet the required accuracy of docking.

[0020] In the above-mentioned winding device, a guide surface is provided at one end of the reel for connecting to the shaft, and the guide surface can guide the end of the shaft to be inserted into the reel. It is understandable that by providing a guide surface on the reel near one end of the shaft, the insertion of the shaft can be facilitated. Exemplarily, the guide surface is configured as an inclined surface. When the shaft is inserted, the guide surface is flared. The deeper the shaft is inserted, the smaller the inner diameter of the reel is, until the reel and the shaft are locked.

[0021] Another object of the present invention is to provide a wire cutting device comprising the winding device as described above.

[0022] Compared with the prior art, the present invention has the following beneficial effects: by arranging a pressure-regulating pipeline on the shaft body to adjust the pressure difference, the two states of the quick-change device can be switched, and the shaft body and the reel can be locked or unlocked for disassembly conveniently and quickly; by arranging a fluid docking module, the connection with the fluid source can be maintained, and the pressure-regulating pipeline on the docking shaft body can be docked in time according to demand, and the lifting mechanism can automatically rise and fall to send the fluid docking module to the area where the shaft body is located for docking, or automatically detach to retract the fluid docking module; by setting an encoder to control the drive motor to rotate to a set angle, the docking hole on the fluid docking module and the pressure-regulating hole on the shaft body are directly opposite to each other, which is convenient for docking.

[0041] For the wire reel winding and unwinding device of the prior art, please refer to the Figure 1 of the accompanying drawings of the specification. Its connection structure mainly includes a main shaft 10, a gland 20 and a bolt 30. During assembly, it is necessary to manually align the gland 20 with the shaft hole of the main shaft 10. However, the clearance between the gland 20 and the shaft hole of the winding and unwinding main shaft 10 is only 0.01 - 0.03 mm, which is difficult for the operator to install.

[0042] For the winding device of the present application, please refer to the Figure 2-Figure 4, specifically including a wire reel 200, a shaft body 100, and a quick-change device 300. A pressure-regulating pipeline 110 is provided on the shaft body 100, and a pressure-regulating hole 111 is provided on the pressure-regulating pipeline 110 for fluid to enter and exit. The quick-change device 300 is arranged between the shaft body 100 and the wire reel 200, enabling a detachable connection between the shaft body 100 and the wire reel 200. Among them, the quick-change device 300 is connected to the pressure-regulating pipeline 110 and has a locked state and an unlocked state, and can be switched to the locked state by the fluid push of the pressure-regulating pipeline 110 or switched to the unlocked state by the fluid backflow of the pressure-regulating pipeline 110.

[0043] It can be understood that the shaft body 100 is used to connect to the wire reel 200 to drive the wire reel 200 to rotate, and the operation of taking in and paying out the cutting wire can be performed. By setting the pressure-regulating pipeline 110 on the shaft body 100 to adjust the pressure difference, the fluid can enter and exit through the pressure-regulating hole 111 of the pressure-regulating pipeline 110. The two states of the quick-change device 300 can be switched by the fluid push or backflow, facilitating the quick locking connection or unlocking and disassembly of the shaft body 100 and the wire reel 200.

[0044] See Figure 5-Figure 7 , the quick-change device 300 includes: a connection seat 310, a connection sleeve 320, and a locking structure. Among them, the connection seat 310 is connected to one end of the shaft body 100. An active rod 330 is provided between the connection seat 310 and the shaft body 100. One end of the active rod 330 is connected to the pressure-regulating pipeline 110. The connection sleeve 320 is detachably connected to the inside of the wire reel 200 and can be sleeved on the connection seat 310. The locking structure is arranged between the active rod 330 and the connection sleeve 320. The locking structure has the above-mentioned locked state and unlocked state. In the locked state, the active rod 330 and the connection sleeve 320 are radially abutted and locked. In the unlocked state, the active rod 330 can axially move relative to the connection sleeve 320 under the action of the fluid of the pressure-regulating pipeline 110.

[0045] It can be understood that the connection seat 310 is connected to the shaft body 100, which can limit the excessive axial movement of the active rod 330 and prevent it from detaching; the connection sleeve 320 is connected to the inside of the wire reel 200 and can form a locking structure with the axially moving active rod 330. The principle of the locking structure is to utilize the pressure difference change of the pressure-regulating pipeline 110 in the shaft body 100 to adjust the axial position of the active rod 330 so that the active rod 330 and the connection sleeve 320 are radially abutted and locked or axially move away.

[0046] The locking structure includes: an elastic member 311 and a locking portion 321. The elastic member 311 is disposed in a limiting hole 312 on a connecting seat 310 and sleeved on a groove 331 on a movable rod 330. The locking portion 321 is disposed on a connecting sleeve 320 and located outside the elastic member 311. Among them, the elastic member 311 can axially move along with the movable rod 330, radially expand along the arc surface of the groove 331 and extend out of the limiting hole 312 to abut against the locking portion 321, or radially contract along the arc surface of the groove 331 into the limiting hole 312 to disengage from the locking portion 321.

[0047] It should be noted that the axial movement of the movable rod 330 is achieved by introducing or sucking back fluid. When introducing fluid, the movable rod 330 is pushed by the fluid to move in the direction close to the connecting sleeve 320. Since the elastic member 311 is limited by the limiting hole 312 and cannot axially move synchronously with the movable rod 330, it only radially contracts synchronously with the contraction of the diameter of the groove 331 at its sleeved position. At this time, it is in the unlocked state. When sucking back fluid, the movable rod 330 is pushed by the fluid to move in the direction away from the connecting sleeve 320, and the groove 331 on the movable rod 330 moves synchronously, causing the elastic member 311 to expand outward and abut against the protruding locking portion 321 on the connecting sleeve 320, that is, the movable rod 330 and the connecting sleeve 320 are locked, and the assembly is completed. Similarly, when introducing fluid again, unlocking can be achieved.

[0048] See Figure 11 , a fluid docking module 400, the fluid docking module 400 is disposed on one side of the shaft body 100 opposite to it; a lifting mechanism 500, the lifting mechanism 500 is disposed below the fluid docking module 400 and can drive the fluid docking module 400 to lift to dock with or disengage from the pressure regulating pipeline 110.

[0049] It can be understood that the pressure regulating pipeline 110 on the shaft body 100 needs to introduce or discharge fluid. If the fluid source is manually docked to the pressure regulating pipeline 110, the efficiency is low and automation cannot be achieved. Therefore, by setting the fluid docking module 400, it can maintain connection with the fluid source and dock with the pressure regulating pipeline 110 on the docking shaft body 100 in a timely manner according to requirements. The lifting mechanism 500 can automatically lift and lower, send the fluid docking module 400 to the area where the shaft body 100 is located for docking, or automatically disengage to retract the fluid docking module 400.

[0050] A quick docking structure 600 is provided between the fluid docking module 400 and the shaft body 100. Please refer to the Figures 8-11, the quick docking structure 600 includes: an upper quick connector 610 and a lower quick connector 620. The upper quick connector 610 is disposed on the pressure regulating hole 111, and the lower quick connector 620 is disposed on the docking hole 410 of the fluid docking module 400. Among them, the upper quick connector 610 can rotate with the shaft body 100 to the axial direction of the lower quick connector 620, so that the cross-sectional projection of the upper quick connector 610 substantially coincides with the cross-sectional projection of the lower quick connector 620.

[0051] It can be understood that by providing the upper quick connector 610 and the lower quick connector 620, the pressure regulating hole 111 and the docking hole 410 can be quickly aligned and connected. When the shaft body 100 rotates, it can drive the upper quick connector 610 to rotate synchronously. When the cross-sectional projection of the upper quick connector 610 coincides with the cross-sectional projection of the lower quick connector 620, the alignment is completed, and the docking can be driven by the lifting mechanism 500.

[0052] The fluid docking module 400 is also provided with a fluid docking pipe 420 for docking with a fluid source. It can be understood that after the fluid docking pipe 420 is docked with the fluid source, it can be kept continuously connected without disassembly and will not interfere with the rotation of the upper shaft body 100 above. Exemplarily, a valve can also be provided in the fluid docking module 400 to facilitate controlling the opening or closing of fluid delivery.

[0053] The driving device 700, please refer to the Figure 3 of the accompanying drawings of the specification. The driving device 700 is disposed on one side of the end of the shaft body 100, and the output end of the driving device 700 is connected to the end of the shaft body 100. Exemplarily, the output end of the driving device 700 and the end of the shaft body 100 can be connected by a coupling. When the output end of the driving device 700 rotates, it can drive the shaft body 100 to rotate synchronously, and the rotation of the shaft body 100 can drive the wire wheel 200 connected thereto to rotate synchronously for taking in and paying out the wire.

[0054] This embodiment further includes a driving device 700, which specifically includes a driving motor and an encoder. The encoder can preset the rotation angle of the driving motor to facilitate the docking of the fluid docking module 400 with the shaft body 100. It can be understood that the driving motor is controlled by the encoder. When the wire wheel 200 and the shaft body 100 need to be reassembled or disassembled, the encoder needs to control the driving motor to rotate a set angle so that the docking hole 410 on the fluid docking module 400 and the pressure regulating hole 111 on the shaft body 100 are directly opposite.

[0055] The lifting mechanism 500 is a cylinder, an electric cylinder or a hydraulic cylinder. Exemplarily, the lifting mechanism 500 can adopt one of a cylinder, an electric cylinder or a hydraulic cylinder to meet the required accuracy for docking.

[0056] One end of the wire reel 200 for connecting to the shaft body 100 is provided with a guiding surface 201, and the guiding surface 201 can guide the insertion of the end of the shaft body 100 into the wire reel 200. It can be understood that by providing the guiding surface 201 near one end of the wire reel 200 close to the shaft body 100, the insertion of the shaft body 100 can be facilitated. Exemplarily, the guiding surface 201 is configured as an inclined surface. When the shaft body 100 is inserted, the guiding surface 201 is in a flared shape. The deeper the shaft body 100 is inserted, the smaller the inner diameter of the wire reel 200 until the wire reel 200 is locked with the shaft body 100.

[0057] Working principle: Please refer to Figure 3 and Figure 4 in the attached drawings of the specification. Before installation, the encoder of the driving device 700 controls the driving mechanism to rotate the shaft body 100 to a suitable angle so that the pressure regulating hole 111 on the shaft body 100 is directly opposite the docking hole 410 on the fluid docking module 400 below. The lifting mechanism 500 drives the fluid docking module 400 to move upward, and the lower quick connector 620 is docked with the upper quick connector 610. At the same time, the wire reel 200 can be automatically clamped by an external manipulator. Through the guiding surface 201 on the side wall of the wire reel 200, the wire reel 200 is partially sleeved on the installation groove 120 of the shaft body 100. Hydraulic fluid is introduced, and the fluid enters the end of the shaft body 100 to push the movable rod 330 to move towards the connecting sleeve 320. The elastic member 311 on the connecting seat 310 contracts until the assembly position is reached. The pressure regulating pipeline 110 is controlled to reduce pressure, so that the hydraulic fluid flows back, and the elastic member 311 on the connecting seat 310 extends to abut against the locking portion 321 on the connecting sleeve 320 to achieve locking, that is, the wire reel 200 and the shaft body 100 are completely assembled, realizing the complete automation of the assembly process.

[0058] Beneficial effects: In the present invention, by providing the pressure regulating pipeline 110 on the shaft body 100 to adjust the pressure difference, two states of the quick-change device 300 can be switched, facilitating the quick locking connection or unlocking and disassembly of the shaft body 100 and the wire reel 200; by providing the fluid docking module 400, the connection with the fluid source can be maintained and docked with the pressure regulating pipeline 110 on the docking shaft body 100 as needed. The lifting mechanism 500 can automatically lift and lower to send the fluid docking module 400 to the area where the shaft body 100 is located for docking or automatically disengage to retract the fluid docking module 400; by providing an encoder to control the driving motor to rotate a set angle, the docking hole 410 on the fluid docking module 400 and the pressure regulating hole 111 on the shaft body 100 are directly opposite, facilitating docking.

[0059] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
