Description
Technical Field
The invention relates to the technical field of printing consumable production, in particular to an automatic positioning device for a tape spool torsion spring for producing a consumable tape box of a tape printer.
Background
Tape cassettes are consumables for tape printers.
The tape box is internally provided with a plurality of tape reels, torsion springs are sleeved on some of the tape reels for ensuring the tensioning degree and the stability of the tape feeding, and correspondingly, clamping positions for fixing two end extension arms of the torsion springs are arranged in the box body of the tape box. In the automated production process of carrying out the tape cassette, these set of tape reels that are equipped with the torsional spring need rotate to accurate angle to the tip extension arm of torsional spring gets into corresponding the position of clamping simultaneously when guaranteeing to put into the box body with the tape reels.
The existing automatic adjusting means for the end part extension arm of the torsion spring on the belt reel is to utilize a grabbing device to grab the belt reel and rotate for a circle, so that the end part extension arm of the torsion spring collides with a rotation stopping structure and is loosened to grab the belt reel after being limited by the rotation stopping structure to rotate. The problem that this mode exists is, though it can guarantee to prevent the tip extension arm of torsional spring to continue to change pendulum to drive the rotatory complete a week of tape spool, but under more circumstances, the tip extension arm of torsional spring has been stopped the structure of changeing when not rotating full a week in the tape spool, and it is elastomeric element to drive the torsional spring, can arouse the energy storage of torsional spring when continuing to be driven the rotation in the tape spool, the torsional spring can take place to kick-back when grabbing device loosens the tape spool, therefore the tip extension arm that makes the torsional spring takes place to turn round and arrives on inaccurate and unpredictable position, then influence subsequent assembly process.
Disclosure of Invention
The invention aims to provide an automatic positioning device for a tape spool torsion spring, which can realize automatic angle positioning of the tape spool with the torsion spring and ensure accurate positioning by using a simple structure and the light weight characteristic of the tape spool.
The automatic positioning device for the torsion spring of the belt reel comprises a rotation stopping structure, a positioning seat and a jacking rotating shaft; the positioning seat is provided with a tape reel placing position and a rotation adjusting position which are communicated from bottom to top, and the positioning seat is provided with a rotation stopping structure at the periphery of the rotation adjusting position; the jacking rotating shaft comprises a bearing shaft body and a central shaft body which are sequentially arranged from bottom to top, wherein a friction bearing surface is arranged on the bearing shaft body, and the periphery of the central shaft body and the periphery above the friction bearing surface form a peripheral position; the jacking rotating shaft can be lifted from a first height position to a second height position; when the jacking rotating shaft is positioned at the first height position, the jacking rotating shaft is positioned below the coil spool placing position; when the jacking rotating shaft is at the second height position, the bearing position is at the rotation adjusting position.
According to the scheme, when the automatic positioning device for the tape spool torsion spring is used for adjusting the position of the torsion spring, the tape spool mounted on the torsion spring is placed at a tape spool placing position, the lifting rotating shaft is started and the tape spool is jacked, the middle shaft body penetrates through a middle hole of the tape spool from bottom to top at the moment, and the bearing shaft body utilizes a friction bearing surface to lift the tape spool until the tape spool reaches a rotation adjusting position; by utilizing the light weight characteristic of the tape reel, the tape reel can be driven to rotate under the friction force of the friction bearing surface when the rotation of the tape reel is not hindered; when the tip extension arm of torsional spring was blockked by the structure of splining, the effort that the coil of strip spool received this moment exceeded frictional force, even the lift pivot still keeps rotating, the coil of strip spool also can't continue to rotate, therefore the tip extension arm of torsional spring keeps on accurate position this moment to accomplish position adjustment.
In a further embodiment, the central shaft can be retracted into the supporting shaft.
Therefore, when the position of the belt reel is adjusted, the belt reel needs to be grabbed from the central hole of the belt reel by the grabbing device and transferred; therefore, in order to avoid the central shaft body from influencing the grabbing of the grabbing device in the middle hole, the central shaft body can be retracted downwards into the bearing shaft body to avoid the grabbing device.
Still further, the automatic positioning device for the tape spool torsion spring further comprises an elastic piece; the elastic element is arranged between the bearing shaft body and the central shaft body, and the central shaft body is kept at a position extending out of the central shaft body under the acting force of the elastic element.
It can be seen from the above that, in order to avoid the end part extension arm of the torsion spring, the periphery of the rotation adjustment position is generally set to be an avoidance space except for the rotation stopping structure, if the central shaft body is driven and retracted by the active driving device before the grabbing device enters the central hole of the belt winding shaft, the belt winding shaft is in a non-positioning state at the moment, and the subsequent work is influenced by the possible position deviation. Therefore, the central shaft body is set to be of an elastic telescopic structure, the central shaft body can be forced to retract downwards by the grabbing device inserted into the middle hole, the arrangement ensures that the tape reel is positioned before the grabbing device grabs, the stable proceeding of subsequent work is ensured, and in addition, the investment of equipment cost is reduced due to the fact that a driving device does not need to be arranged.
Further, the positioning seat comprises a guide surface, and the guide surface is arranged on the periphery of the placement position of the tape reel.
It can be seen from above that, the in-process that the tape spool was sent into the tape spool and is put the position can be guided by guiding surface, therefore can guarantee that the tape spool finally reaches the target location, guarantees that the center pin physical stamina is accurate and inserts the mesopore of tape spool.
The entering direction of the coil reel placing position is the horizontal direction or is inclined to the horizontal direction; the guide surface includes a straight surface portion and a curved surface portion which are sequentially arranged in the entering direction.
Therefore, as the jacking rotating shaft and the grabbing device work vertically, the strip coil shaft is fed into the strip coil shaft placing position along the horizontal direction or slightly inclined to the horizontal direction, so that the production rhythm is prevented from being influenced by station overlapping; in addition, because the tape reel has a circular outer contour, the straight line part guides the tape reel from the inlet, and the curved line part is matched with the circular outer edge of the tape reel for guiding so as to more easily guide the tape reel to a position aligned with the center of the jacking rotating shaft.
In another still further scheme, the entering direction of the tape reel placing position is a horizontal direction or an inclined direction to the horizontal direction; the positioning seat comprises two guide surfaces which are arranged in a step shape from bottom to top or from top to bottom.
Therefore, as the jacking rotating shaft and the grabbing device work vertically, the strip reel is fed into the strip reel placing position along the horizontal direction or slightly inclined to the horizontal direction, so that the phenomenon that the production rhythm is influenced by station overlapping can be avoided; in addition, because the two axial ends of the tape spool are respectively provided with two retaining rings with different outer diameters, by utilizing the structural characteristics of the tape spool, the two guide surfaces arranged in a step shape are respectively matched with the two retaining rings in a guide way, so that the parallelism between the axis of the tape spool and the axis of the central shaft body can be ensured.
Still another scheme is further, at the periphery of rotation adjustment position, the position of positioning seat outside the structure that splines forms the periphery and dodges the space.
From top to bottom, because the tip extension arm of torsional spring stretches out to the periphery of taking the spool, can change to and rotate the structure complex position with ending for guaranteeing the tip extension arm, better, except that ending the structure, other positions should give and dodge the space.
The positioning seat comprises a bottom wall, and the bottom wall is positioned below the tape reel placing position; the bottom wall forms an avoidance opening, and the jacking rotating shaft can penetrate through the avoidance opening.
It is from top to bottom visible, the diapire is arranged in the support and is located the tape spool and place the position, dodges the mouth and is used for supplying the jacking pivot to pass and enter the tape spool and place the position.
The entering direction of the coil reel placing position is the horizontal direction or is inclined to the horizontal direction; the bottom wall includes a ramp surface disposed at an entrance to the tape spool placement location.
As can be seen, the ramp surface is used to engage the transport path with the spool placement location so that the spool can more easily enter the spool placement location.
The rotation stopping structure is detachably arranged on the positioning seat, and/or the rotation stopping structure is arranged on the positioning seat in a position-adjustable manner.
It is thus clear that this setting is convenient for adjust in real time or change in time the position that blocks of splining the structure according to actual conditions down.

The upper surface 209 of the positioning base 2 is provided with four screw holes 29 arranged in a rectangular array, and the screws pass through the long counter bores 310 and then are locked with the screw holes 29, so that the rotation-stop member 3 can be detachably and adjustably mounted on the positioning base 2 and is located on the periphery of the rotation adjusting position 220.
Referring to fig. 7, the lifting spindle 4 includes a supporting spindle body 41 and a central spindle body 42 with a smaller outer diameter, at least the upper portion of the supporting spindle body 41 is cylindrical and has a telescopic channel 410 inside, the central spindle body 42 is installed in the telescopic channel 410 in a vertically telescopic manner, and a spring is placed in the telescopic channel 410 and abuts against the supporting spindle body 41 and the central spindle body 42, the central spindle body 42 is forced to move upwards to extend beyond an upper end surface 411 of the supporting spindle body 41 under the restoring force of the spring and is kept in this state, and at this time, an annular supporting position 420 for supporting the tape spool is formed above the upper end surface 411 and on the periphery of the central spindle body 42; pressing down on the central axle 42 causes the central axle 42 to move downward and retract into the telescoping channel 410 and compress the spring.
Wherein, the upper end face 411 is a friction bearing face of the invention, the upper end face 411 is an annular plane, and the upper end face 411 is used for bearing a tape reel; when the spool is in the holding position 420, the lifting spindle 4 rotates and the spool is not stopped, the maximum static friction force sufficient to keep the lifting spindle 4 and the spool rotating synchronously can be generated by the cooperation of the upper end surface 411 under the self-weight of the spool. Generally, the upper end surface 411 does not need to be subjected to a special surface roughness treatment for increasing the degree of friction. In addition, the central shaft body 42 is provided with a profile in which the outer diameter is gradually reduced from the bottom up to facilitate insertion into the central hole of the tape reel.
Referring to fig. 4, 5 and 8, the elevating rotation shaft 4 is at the lower limit position in the initial state. When the tape reel 9 is fed from the inlet 201 into the tape reel placing position 210 to the target position with the first guide surface 241 and the second guide surface 242 in guiding engagement with the first stopper ring 901 and the second stopper ring 902, respectively, the axial center of the tape reel 9 is aligned with the axial center of the elevating rotary shaft 4, and the torsion spring 91 is located in the escape opening 202 and the end extension arm of the torsion spring 91 is forced down by the bottom wall 23 to the deep portion 219.
Referring to fig. 9, the lifting spindle 4 is then raised to the upper limit position, in the process, the central shaft 42 penetrates into the central hole 90 of the tape reel 9 from bottom to top and the upper end surface 411 of the supporting shaft 41 abuts against the lower end surface of the tape reel 9, and at this time, the tape reel 9 is located in the supporting position 420 and is lifted by the lifting spindle 4. When the lifting spindle 4 is in the upper limit position, the tape reel 9 located in the holding position 420 is located in the rotation adjustment position 220. Of course, the lifting rotating shaft 4 can keep rotating for lifting movement, and the starting and stopping control of the motor 52 is not needed to be considered in the setting, and the working effect is not influenced.
Referring to fig. 10 again, the lifting spindle 4 rotates, and the tape reel 9 keeps the lifting spindle 4 rotating synchronously under the maximum static friction force generated by the engagement of the upper end surface 411 under its own weight; referring to fig. 11 again, until the end extension arm 919 of the torsion spring 91 is blocked by the rotation stop slope 320 of the rotation stop member 3, the spool 9 stops rotating while the lifting spindle 4 keeps rotating, and the end extension arm 919 keeps abutting against the rotation stop slope 320.
Since the tape reel 9 formed of plastic has a small weight, when the lifting spindle 4 rotates and the lightweight tape reel is stopped by the rotation stopping member 3, the reaction torque provided by the rotation stopping member 3 is much greater than the maximum static friction force, thereby preventing the lifting spindle 4 from rotating and maintaining the end portion extension arm 919 at a target position without elastically bending the end portion extension arm 919. On the contrary, if the part to be positioned has a large weight, the maximum static friction force generated between the part to be positioned and the bearing shaft body is large, and because the torsion spring is an elastic component, when the end part extension arm of the torsion spring is blocked by the rotation stopping component, the bending deformation of the end part extension arm can be caused, so that the part to be positioned can not be forced to stop rotating, and the torsion spring can be damaged; or may cause the torsion spring to rebound out of the target position. Therefore, the automatic positioning device for the tape spool torsion spring of the invention utilizes the light weight characteristic of the tape spool 9 to ensure that the torsion spring is accurately limited at a target position on the premise of not damaging the torsion spring.
Referring to fig. 12, the grasping unit 6 is then inserted into the central hole 90 of the tape reel 9 from top to bottom to force the central shaft 42 to move downward and retract into the supporting shaft 41, and the grasping portion of the grasping unit 6 is expanded outward to engage with the inner wall surface of the tape reel 9 to grasp the tape reel 9 and perform a transferring operation.
Second embodiment of automatic positioning device for torsion spring with reel
Referring to fig. 13, in the present embodiment, the central shaft body 42' is of a non-retractable structure. Because the height of the central shaft body 42' is smaller than the height of the central hole 90 of the tape reel 9, with this arrangement, only the avoiding position needs to be arranged on the grabbing device 6', and the grabbing device 6' can also penetrate into the central hole 90 of the tape reel 9 from top to bottom for grabbing.
In other embodiments, the central shaft is telescopically disposed on the supporting shaft, and the central shaft is driven by a corresponding driving device to extend and retract.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
