Referring to fig. 1, fig. 2 and fig. 3, an unreeling mechanism according to an embodiment of the invention includes a pushing member 10, a rotating shaft 20, an unreeling shaft 30, a stock shaft 40 and a driving assembly 50.
The rotary shaft 20 is rotatable about its own axis and is movably disposed along its own axis with respect to the push member 10. The unreeling shaft 30 is coaxially disposed on the rotating shaft 20 and rotates synchronously with the rotating shaft 20, so that the unreeling shaft 30 can rotate along with the rotating shaft 20 to realize unreeling. The stock shaft 40 is coaxially disposed on the rotary shaft 20 and rotatable about its own axis with respect to the rotary shaft 20, so that the stock shaft 40 does not rotate with the rotary shaft 20 when the rotary shaft 20 rotates. The driving assembly 50 is used for driving the rotating shaft 20 to rotate around the axis thereof and driving the stock shaft 40 to move along the axis thereof relative to the pushing member 10.
The ends of the stock shaft 40 and the unreeling shaft 30 facing each other may be butted with each other, so that the pushing member 10 can push the roll sleeved on the stock shaft 40 onto the unreeling shaft 30 in the process that the stock shaft 40 moves along the axial direction thereof relative to the pushing member 10.
The unreeling mechanism is characterized in that at least one standby roll is sleeved on the standby roll 40, and one roll is sleeved on the unreeling roll 30. The driving assembly 50 drives the rotating shaft 20 to rotate, so that the unreeling shaft 30 is driven to rotate to unreel. Since the stock shaft 40 is rotatable relative to the rotary shaft 20, the stock shaft 40 does not rotate with the rotary shaft 20, and the stock rolls on the stock shaft 40 are prevented from rotating.
When the unreeling of the material roll on the unreeling shaft 30 is completed and the reel replacement is needed, the driving assembly 50 stops driving the rotating shaft 20 to rotate, and at this time, the working material belt is cut off, the driving assembly 50 drives the material preparation shaft 40 to move along the axis of the pushing member 10 relative to the pushing member 10, so as to drive the rotating shaft 20 and the unreeling shaft 30 to move along the axial direction of the rotating shaft 20 relative to the pushing member 10 together, and the pushing member 10 pushes the material roll on the material preparation shaft 40 to the unreeling shaft 30. The driving assembly 50 drives the standby shaft 40 again along the own axis to move back to the initial position (at this time, the rotating shaft 20 and the unwinding shaft 30 are returned to the initial position together with the standby shaft 40) with respect to the pushing member 10, and then connects the beginning end of the standby roll on the unwinding shaft 30 with the cut working tape. The driving assembly 50 drives the rotating shaft 20 to rotate, so that the unreeling shaft 30 is driven to rotate to realize continuous unreeling.
In this way, the unreeling mechanism realizes reel replacement by arranging the unreeling shaft 30 and the material preparation shaft 40 which can be mutually butted on the rotating shaft 20 and pushing the standby material reel on the material preparation shaft 40 onto the unreeling shaft 30 by the pushing piece 10, so that two sets of unreeling mechanisms which are mutually standby are avoided, the device structure is simplified, and the occupied space is reduced.
It will be appreciated that at the time of changing the roll, the backup roll 10 will push the empty roll (i.e. the roll after unreeling) on the unreeling shaft 30 along the unreeling shaft 30 while pushing the backup roll on the backup shaft 40 onto the unreeling shaft 30, and will be replaced by the backup roll. After the reel change is completed, the driving assembly 50 drives the rotating shaft 20 to rotate so as to drive the unreeling shaft 30 to rotate, and the standby reels and the empty reels on the unreeling shaft 30 rotate together with the unreeling shaft 30. Because the empty rolls have a smaller mass (i.e., small moment of inertia), the effect on the rotation of the unwind spool 30 is smaller and the reserve rolls on the unwind spool 30 can be unwound normally.
It should be noted that, the driving assembly 50 drives the stock shaft 40 to move along the axis of the pushing member 10, so that on one hand, the stock roll on the stock shaft 40 can be pushed onto the unreeling shaft 30, thereby realizing roll replacement; on the other hand, the driving assembly 50 can be used to drive the material preparing shaft 40 to move along the axial direction thereof, so as to drive the unreeling shaft 30 to move along the axial direction thereof, and further realize deviation correction (i.e. further having a deviation correcting function) on the material belt unreeled and outputted by the unreeling shaft 30. That is, the two functions of reel changing and deviation correcting can be realized by driving the feed preparation shaft 40 along the axis by the driving component 50, so that the structure of the equipment is simplified, the space is saved, and the cost is reduced.
In an embodiment of the invention, the unwind spool 30 has at least two mounting locations for the jacket-up roll disposed axially therealong. The stock shaft 40 has at least one stock position for sheathing the stock roll (i.e., the stock roll) arranged in the axial direction thereof. And, the number of mounting positions on the unreeling shaft 30 is at least one more than the number of stock positions on the stock shaft 40. Thus, before the unreeling mechanism starts the unreeling operation, a roll is sleeved on an installation position closest to the material preparation shaft 40 on the unreeling shaft 30, and a standby roll is sleeved on each material preparation position on the material preparation shaft 40. When unreeling of the reserve rolls on the unreeling shaft 30 is completed and the reel replacement is required, the pushing member 10 pushes all the reserve rolls on the reserve shaft 40 to the unreeling shaft 30, so that one reserve roll closest to the unreeling shaft 30 moves to one mounting position of the unreeling shaft 30 closest to the reserve shaft 40, and the empty rolls on the unreeling shaft 30 are pushed to the adjacent mounting position by the reserve rolls. This is cycled until all of the reserve rolls on the reserve shaft 40 are pushed onto the unwind shaft 30 and unwinding is completed. Since the number of mounting locations on the unwind shaft 30 is at least one more than the number of stock locations on the stock shaft 40, it is ensured that the unwind shaft 30 is able to accommodate all the stock rolls on the lower stock shaft 40.
Referring to fig. 1 and 4, in the embodiment of the present invention, an expanding assembly 32 is disposed on the unreeling shaft 30, and the expanding assembly 32 can be controlled to expand along the radial direction of the unreeling shaft 30 to expand the material roll on the unreeling shaft 30, i.e. fix the material roll relative to the unreeling shaft 30. In this manner, the inflation and deflation of the rolls on the unwind shaft 30 may be accomplished by the inflation assembly 32. When unreeling is required, the expansion assembly 32 expands the material roll on the unreeling shaft 30, so that the material roll synchronously rotates along with the unreeling shaft 30, and unreeling is achieved. When a roll change is required, the expansion assembly 32 unwinds the roll so that the backup roll can push the empty roll on the unwind shaft 30 away from the backup shaft 40 as the push member 10 pushes the backup roll to facilitate the backup roll to slide onto the unwind shaft 30.
In the embodiment, the outer circumferential surface of the unreeling shaft 30 is provided with a mounting groove 31. The expansion assembly 32 includes expansion blocks 321 and air bags 322 all disposed in the mounting groove 31. The bladder 322 is positioned between the expansion block 321 and the bottom wall of the mounting groove 31 and is in communication with an external air source so that the bladder 322 can be inflated or deflated by the external air source. When the air bag 322 is inflated to expand, the expanding block 321 can be pushed to penetrate out of the mounting groove 31 along the radial direction of the unreeling shaft 30, so as to prop against the inner wall of the material roll, and further expand the material roll. When the roll is not required to be inflated, the air bag 322 is deflated and contracted, so that the inflation block 321 is retracted into the mounting groove 31 in the radial direction of the unreeling shaft 30, and the roll is released, so that the roll can slide along the unreeling shaft 30.
In particular to the embodiment, the rotating shaft 20 has a central bore 21 extending along its axis. One end of the central bore 21 is connected to an external air source. The rotating shaft 20 is provided with a first air passage communicated with the central hole 21 along the radial direction thereof, the unreeling shaft 30 is provided with a second air passage communicated with the first air passage and the mounting groove 31 along the radial direction thereof, and the air tap of the air bag 322 is communicated with the second air passage.
Further, the mounting groove 31 extends longitudinally along the axial direction of the unreeling shaft 30, and the expanding block 321 also extends longitudinally along the axial direction of the unreeling shaft 30, so as to facilitate ensuring that each material roll on the unreeling shaft 30 is expanded or unreeled simultaneously. Preferably, the mounting groove 31 and the expansion block 321 are approximately the same length as the unwind shaft 30.
Further, a plurality of mounting grooves 31 are formed in the outer peripheral surface of the unreeling shaft 30, the plurality of mounting grooves 31 are arranged at intervals along the circumferential direction of the unreeling shaft 30, and each mounting groove 31 is provided with an expanding assembly 32. Therefore, the material rolls are expanded by utilizing the plurality of expansion assemblies 32, the stability of the material rolls is ensured, and the unreeling quality is improved.
In the embodiment, two side walls at the opening of the mounting groove 31 protrude into the mounting groove 31 to form a blocking portion 311. The expansion block 321 comprises a limiting part and an expansion part connected with the limiting part, the limiting part is positioned in the mounting groove 31, and in the process that the expansion block 321 moves along the radial direction of the unreeling shaft 30 under the pushing of the air bag 322, the expansion part can extend out of the mounting groove 31 to prop against the inner wall of the material roll, so that the material roll is expanded; and the limiting part can prop against the blocking part 311 to prevent the expansion block 321 from continuously extending out of the mounting groove 31 to be separated from the unreeling shaft 30.
In the embodiment of the present invention, the unreeling shaft 30 is movable in the own axial direction with respect to the rotation shaft 20. The unreeling mechanism further comprises a moving driving member 34, wherein the moving driving member 34 is connected to the rotating shaft 20 and the unreeling shaft 30, and is used for driving the unreeling shaft 30 to move along the axial direction of the unreeling shaft relative to the rotating shaft 20, so that the end parts of the unreeling shaft 30 and the material preparing shaft 40, which face each other, are butted or separated. In this way, when unreeling is required, the moving driving member 34 drives the unreeling shaft 30 to move away from the stock shaft 40 in the axial direction thereof, so that the ends of the unreeling shaft 30 and the stock shaft 40 facing each other are separated, thereby avoiding the influence of the stock shaft 40 on the rotation of the unreeling shaft 30 when unreeling. When a reel change is required, the moving driving member 34 drives the unreeling shaft 30 to axially move along the unreeling shaft 30 to approach the stock shaft 40, so that the ends of the unreeling shaft 30 and the stock shaft 40 facing each other are butted, and the stock reel on the stock shaft 40 is pushed against the unreeling shaft 30.
In particular, in the embodiment, the unreeling shaft 30 includes a reel changing position and an unreeling position during moving along its own axis relative to the rotating shaft 20. When the unwind shaft 30 is in the reel change position, the ends of the unwind shaft 30 and the stock shaft 40 facing each other are butted so as to push the stock reel on the stock shaft 40 against the unwind shaft 30. When the unreeling shaft 30 is located at the unreeling position, the ends of the unreeling shaft 30 and the stock shaft 40 facing each other are separated from each other, so that the stock shaft 40 is prevented from affecting the rotation of the unreeling shaft 30 at the unreeling time.
In particular, in the embodiment, the moving driver 34 is mounted to one end of the rotating shaft 20. The unreeling shaft 30 is a hollow shaft, and a push plate 33 is fixedly connected inside the unreeling shaft. The unreeling shaft 30 is sleeved at one end of the rotating shaft 20, on which the movable driving member 34 is mounted, so that the movable driving member 34 is positioned in the unreeling shaft 30, and the driving end of the movable driving member 34 is conveniently connected with the push plate 33. Thus, the driving end of the moving driving member 34 drives the push plate 33 to move along the axial direction of the unreeling shaft 30, so that the unreeling shaft 30 moves synchronously with the push plate 33.
Alternatively, the unreeling shaft 30 and the rotating shaft 20 can be connected through a key, so that the unreeling shaft 30 and the rotating shaft 20 can synchronously rotate, and the unreeling shaft 30 can move along the axial direction of the unreeling shaft relative to the rotating shaft 20. For example, a key groove extending longitudinally in the axial direction of the rotary shaft 20 is provided between the unreeling shaft 30 and the rotary shaft 20, and a key is slidably provided in the key groove in the longitudinal extending direction of the key groove.
Alternatively, the movement driver 34 may be an air cylinder. Further, the unreeling mechanism further comprises an air pipe disposed in the center hole 21 of the rotary shaft 20, one end of which is connected to an external air source, and the other end of which is connected to the moving driving member 34, i.e., the external air source is connected to the moving driving member 34 through the air pipe. More specifically, the movement driver 34 is a single-acting cylinder.
Referring to fig. 1, 2 and 3, in the embodiment of the present invention, the stock shaft 40 is movably connected to the pushing member 10 along the axial direction thereof. The driving assembly 50 includes a movable seat 51, a first driving structure 53 and a second driving structure 55. The moving seat 51 is movably connected to the pushing member 10 along the axial direction of the stock shaft 40 and is fixedly connected to the stock shaft 40, and the moving seat 51 is located at a side of the pushing member 10 away from the unwinding shaft 30. The first driving structure 53 is connected to the moving seat 51 and the pushing member 10, and is used for driving the moving seat 51 to move along the axial direction of the stock shaft 40 relative to the pushing member 10, so as to drive the stock shaft 40, the rotating shaft 20 and the unwinding shaft 30 to move synchronously along the axial direction of the stock shaft 40, so as to facilitate reel change. The second driving structure 55 is disposed on the moving seat 51 and is in transmission connection with the rotating shaft 20, so as to drive the rotating shaft 20 to rotate around its own axis, and further drive the unreeling shaft 30 to rotate around its own axis, so as to realize unreeling.
In particular embodiments, the first drive structure 53 includes a lead screw 532, a lead screw nut 533, and a reload drive 531. The screw 532 is rotatably connected to the pushing member 10 around its own axis and is parallel to the stock shaft 40. The screw nut 533 is screwed to the screw 532 and is fixedly connected to the movable seat 51. The material changing driving member 531 is connected to the pushing member 10 and is in driving connection with the screw 532, so as to drive the screw 532 to rotate around its own axis. Thus, when a roll is required to be replaced, the feed screw 532 is driven by the feed-changing driving member 531 to rotate around the axis thereof, so that the moving seat 51 moves along with the feed screw nut 533 along the axial direction of the feed-preparing shaft 40, and further drives the feed-preparing shaft 40, the rotating shaft 20 and the unreeling shaft 30 to move along the axial direction of the feed-preparing shaft 40 together, so that the backup roll on the feed-preparing shaft 40 is pushed onto the unreeling shaft 30 by the pushing member 10, and the roll replacement is realized. Alternatively, the reload driving member 531 may be a motor.
Further, the movable seat 51 may be connected to the pushing member 10 through the guide rod 511. That is, one end of the guide rod 511 is fixedly connected to the pushing member 10, and the moving seat 51 is slidably connected to the guide rod 511. Alternatively, the reload driving member 531 may be mounted on the side of the guide bar 511 facing away from the pushing member 10.
In the embodiment, the second driving structure 55 includes a rotary driving member 551 disposed on the moving seat 51, where the rotary driving member 551 is in transmission connection with the rotary shaft 20, so as to drive the rotary shaft 20 to rotate around its own axis, and thus drive the unreeling shaft 30 to rotate around its own axis to implement unreeling.
Further, in one embodiment, the rotary drive 551 may be drivingly connected to the rotary shaft 20 using a gear arrangement. That is, the driving gear 552 is mounted on the output shaft of the rotation driving member 551, the driven gear 553 is mounted on the rotation shaft 20, and the driving gear 552 and the driven gear 553 are engaged with each other, so that the rotation driving member 551 drives the driving gear 552 to rotate, so that the driven pulley 553 is driven, and the rotation shaft 20 is driven to rotate. Of course, the rotary driving member 551 is not limited to the gear transmission structure and the rotary shaft 20, and may be other transmission structures, such as a belt transmission structure, etc., which are not limited herein.
In the embodiment, the material preparing shaft 40 is a hollow shaft and is sleeved outside the rotating shaft 20. One end of the rotating shaft 20 penetrates out of the material preparing shaft 40 and is in transmission connection with the rotating driving piece 551. The other end of the rotating shaft 20 penetrates the stock shaft 40 and is used for mounting the unreeling shaft 30. Alternatively, the stock shaft 40 may be sleeved outside the rotating shaft 20 through a bearing, so that the stock shaft 40 can rotate relative to the rotating shaft 20, i.e. when the rotating shaft 20 rotates, the stock shaft 40 does not rotate along with the rotating shaft 20.
In particular to one embodiment, the pusher 10 may be a mounting plate. The stock shaft 40 may be mounted to the mounting plate by a sliding sleeve, so that the stock shaft 40 may be movably connected to the mounting plate along its own axis. That is, the first driving structure 53 is used to drive the standby shaft 40, the rotating shaft 20 and the unreeling shaft 30 to move along the axial direction, so as to realize the relative movement between the mounting plate and the standby shaft 40, and then the mounting plate is used to push the standby roll on the standby shaft 40 to move to the unreeling shaft 30 for realizing roll replacement, so that no additional component for pushing the standby roll is needed, the structure of the device is further simplified, and the occupied space is reduced.
Of course, in other embodiments, the stock shaft 40 may be fixedly connected to the mounting plate, and an abutment member is additionally provided, and the first driving structure 53 is drivingly connected to the abutment member, so as to drive the abutment member to move along the axial direction of the stock shaft 40, so as to push the stock roll on the stock shaft 40 onto the unwinding shaft 30. That is, in the present embodiment, the rotation shaft 20, the stock shaft 40 and the mounting plate do not move in the axial direction during pushing, but the first driving structure 53 drives the pushing member to move, so as to realize the relative movement of the pushing member and the stock shaft 40.
Based on the unreeling mechanism, the invention also provides an automatic reel changing device, which comprises the unreeling mechanism in any embodiment.
In an embodiment, the automatic reel changing device further comprises a cutting mechanism and a tape receiving mechanism, the cutting mechanism is used for cutting off the material tape which is fed and unreeled and output by the unreeled reel 30, and the tape receiving mechanism is used for bonding the cut material tape with the head end of the standby material reel which is changed to the unreeled reel 30. It should be noted that the cutting mechanism and the tape splicing mechanism may be implemented by using relatively mature existing technologies, and thus will not be described in detail herein.
