Description

Anti-vibration adjusting device of deviation correcting sensor

Technical Field

The invention relates to a coiled material deviation rectifying system, in particular to an anti-vibration adjusting device of a deviation rectifying sensor, which is used for the stable work of a narrow deviation rectifying device sensor.

Background

De-registration is the technical operation of a manufacturer to keep the side of a web neat and consistent during the process of spraying, printing, die cutting, laminating, slitting or other web winding, since misalignment of the web edges can cause errors in subsequent steps.

The deviation-correcting sensor sends out infrared light, ultrasonic waves, laser or visible light to monitor the operation of the coiled material on the equipment and send signals to the controller. After the controller finds that the coiled material has position drift, the controller controls the deviation rectifying frame to swing through the driver according to an instruction preset by a controller so as to correct the position of the coiled material. The automatic coiled material deviation rectifying system can monitor the edge position of a coiled material by using a photoelectric sensor, send a measured position error signal into the controller, and control the driving motor to correct the coiled material at a deviation position to a correct position after the control unit judges and processes the position error signal.

Fig. 1 is a schematic structural diagram of an embodiment of a sensor adjustment device. As shown in fig. 1, the sensor adjustment device includes a square steel 101, a rough adjustment slider 103, a guide plate 105, and a fine adjustment knob 107.

Two ends of the square steel 101 are respectively connected with a fine adjustment knob 107 and a guide plate 105, and the fine adjustment knob 107 and the guide plate 105 are respectively fixed on equipment to be monitored through an installation support plate 109. The fine adjustment knob 107 is screwed to one end (adjustment end) of the square bar 101, and can rotate in different directions to drive the square bar 101 to move left and right in the transverse direction. The other end (guide end) of the square bar 101 is movably attached to a guide plate 105. In this embodiment, the guide plate 105 is provided with a groove matching the guide end of the square steel 101, and the guide end of the square steel 101 can be inserted into the groove with a certain clearance from the inner wall of the groove, so that the guide end can move a correspondingly small amount in the groove during fine adjustment, but is limited and guided by the groove. In some embodiments, a limit stop pin 115 may be further disposed at the connection between the guide plate 105 and the guide end of the square steel 101 to further limit the movement of the guide end, so as to prevent accidental falling.

The rough adjusting slide block 103 is sleeved on the square steel 101 and can slide left and right on the square steel 101 along the transverse direction. The sensor 111 is fixed to the rough adjustment slider 103 and can move in accordance with the movement of the rough adjustment slider 103. A locking screw 113 is arranged on the rough adjusting slide block 103 and is used for fixing the rough adjusting slide block 103 on the square steel 101. In this embodiment, two locking screws 113 are provided, which are fixed in the up-down and front-rear directions, respectively, to make the fixing more firm.

During adjustment, the rough adjustment slider 103 is first moved left and right on the square steel 101 in the lateral direction to roughly adjust the position of the sensor 111, and the rough adjustment slider 103 is fixed at the position by the locking screw 113. The position of the square bar 101 is then adjusted by rotating the fine adjustment knob 107, thereby finely adjusting the position of the sensor 111.

Due to the clearance between the guide end of the square steel 101 and the guide plate 105 and the influence of assembly tolerance, the square steel 101 may vibrate (for example, in the up-down or front-back direction) during the operation of the device to be monitored, thereby affecting the measurement accuracy and accuracy of the sensor. In some embodiments, a fastening mechanism such as a screw may be provided at the guide plate 105 to lock the square steel 101 after fine adjustment so as not to generate vibration.

Fig. 2 is a schematic structural diagram of an embodiment of the anti-vibration adjustment apparatus of the present application. As shown in fig. 2, the anti-vibration adjustment device includes a cross bar 201, a rough adjustment slider 203, a fine adjustment knob 207, and a fine adjustment slider 221.

The cross bar 201 is a straight bar made of a hard material, such as a rigid straight bar of square steel. In the present application, the axis of the crossbar 201 is the transverse direction or the left-right direction, and in some implementations, the crossbar 201 is mounted on the device to be monitored in such a way that the axis direction coincides with the running direction of the web on the device to be monitored.

The rough adjustment slider 203 is movably mounted on the crossbar 201 and can move laterally along the crossbar 201. A sensor 211 is fixed to the rough adjusting slider 203 to monitor a specific position on the device to be monitored. In this embodiment, the sensor 211 is a deskew sensor. The rough adjusting slide block 203 is provided with a locking screw 213, and the locking screw 213 can fix the rough adjusting slide block 203 and the cross rod 201 when being screwed.

The fine adjustment slider 221 is connected to the crossbar 201 and is inserted into a slide groove 301 (see fig. 3) fixedly provided on the device to be monitored, so that the crossbar 201 can move laterally along the slide groove 301. The fine adjustment knob 207 is fixed on the device to be monitored, and is connected to one end (adjustment end) of the crossbar 201, and is used for driving the crossbar 201 to move transversely. In this embodiment, fine adjustment knob 207 is fixed to the device to be monitored by mounting plate 209 and is threadedly connected to the adjustment end of crossbar 201, and can drive crossbar 201 to move laterally relative to the device to be monitored by rotation. By rotating fine adjustment knob 207 and driving crossbar 201 to move laterally by way of a threaded connection, crossbar 201 can be adjusted more precisely for small amounts of displacement and also for ease of adjustment during operation of the device.

Fig. 3A and 3B are schematic structural views of different angles of an embodiment of the chute provided on the device to be monitored in the present application. As shown in fig. 3A and 3B, the chute 301 is fixedly provided laterally on a device to be monitored 302 (only a schematic partial structure of the device to be monitored is shown in the drawing).

The sliding chute 301 includes upper and lower guiding walls 303, the guiding walls 303 extend outward from one side of the device 302 to be monitored, and a groove or a concave structure is formed between the two guiding walls 303 for the fine tuning sliding block 221 to be embedded therein. In some embodiments, the front ends of the two guiding walls 303 are respectively inclined toward each other to form a V-shaped structure, so as to better limit and guide the fine tuning slider 221 embedded therein. Accordingly, the surface of the vernier slider 221 contacting the inner side of the guide wall 303 is also provided with a corresponding inclined slope, forming a V-like shape, to maintain good contact with the inner side of the guide wall 303. The two guide walls 303 have a gap between their front ends, and an opening or gap is formed in the bottom of the V-shape so that the fine adjustment slider 221 can be connected to the cross bar 201 through the opening or gap.

In some embodiments, the chute 301 may be integrally formed with the device to be monitored 302, extending from a side of the device to be monitored 302, and may be formed by, for example, extruding an aluminum alloy profile. In other embodiments, the chute 301 may be a separate structure, and may be fixed to the device to be monitored 302 by riveting, snapping, hinging, screwing, or the like.

Fig. 4A and 4B are schematic structural diagrams of different angles of an embodiment of the vibration control device installed on a device to be monitored. As shown in fig. 4A and 4B, the fine adjustment knob 207 is fixed to the device to be monitored 302 by a mounting bracket 209. The cross bar 201 is connected to the device 302 to be monitored by a fine adjustment slider 221 embedded in the sliding groove 301, and can move laterally relative to the device 302 to be monitored by the movement of the fine adjustment slider 221 in the sliding groove 301. A locking screw 213 is mounted on the side of the rough adjusting slider 203 remote from the slide channel 301 for ease of operation. In some embodiments, the cross bar 201 may be a prism such as a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, or various regular or irregular prisms, or a cylinder.

In this embodiment, the cross-bar 201 has a transverse rib. The locking screw 213, when tightened, fastens to a rib of the rail 201 remote from the slot 301, so that the rough adjustment block 203 can be securely fastened to the rail 201 by means of a locking screw.

Fig. 5 is an exploded view of an embodiment of the anti-vibration adjustment apparatus of the present application. Fig. 6 is a sectional view of a mounting structure in a radial direction of a cross bar of an embodiment of the vibration damper according to the present application. As shown in fig. 5 and 6, the cross bar 201 is provided with a hole 530, and a connection screw 535 passes through the hole 530 to fixedly connect the fine adjustment slider 221 to the cross bar 201. The connection screw 535 is screwed to the fine adjustment slider 221, and in some embodiments, a screw glue is injected between the connection screw 535 and the screw thread of the fine adjustment slider 221 to prevent the connection screw 535 and the fine adjustment slider 221 from being loosened by vibration during the operation of the device. In this embodiment, the attachment screw 535 is a countersunk screw, the head of which can be caught on the outside of the crossbar 201 (i.e., the side away from the chute 301).

A sliding sleeve 531 is further disposed between the fine adjustment slider 221 and the cross bar 201. A hole is also formed in the sliding sleeve 531, and the connecting screw 535 passes through the cross bar 201 and the sliding sleeve 531 to connect with the fine adjustment slider 221, and can fix the fine adjustment slider 221 and the cross bar 201 when screwing, so that the fine adjustment slider 221 is tightly attached to the inner side of the sliding groove 301 (i.e. the inner side of the guide wall 303), and the sliding sleeve 531 is tightly attached to the outer side of the sliding groove 301 (i.e. the outer side of the guide wall 303), i.e. the guide wall 303 of the sliding groove 301 is sandwiched, thereby fixing the cross bar 201 on the sliding groove 301, and enabling the cross bar 201 to move only along the sliding groove. During the lateral movement of the crossbar 201 along the slide groove 301, the slide sleeve 531 and the fine adjustment slider 221 slide with the guide wall 303 interposed therebetween. In some embodiments, the fine adjustment slider 221 and the sliding sleeve 531 are made of lubricated engineering Plastic (POM) to make the sliding smoother. In some embodiments, the V-shaped fine adjustment sliding block 221 made of engineering plastic is matched with the V-shaped sliding groove 301 made of aluminum alloy, so that the guiding performance is good during sliding, and the sliding groove is not easy to wear.

Between the sliding sleeve 531 and the cross bar 201, an elastic member 533 is further provided. In this embodiment, the side of the crossbar 201 adjacent to the sliding groove 301 has a recess, and the sliding sleeve 531 and the elastic member 533 are disposed in the recess. When the connection screw 535 locks the cross bar 201 and the fine adjustment slider 221, the elastic member 533 is compressed by the compression, and the generated elastic force can be used as a pre-tightening force to push the sliding sleeve 531 against the outer side of the sliding groove 301, so that when the cross bar 201 moves along the sliding groove 301, the sliding sleeve 531 and the outer side of the sliding groove 301 always keep close contact, and the cross bar 201 can be more firmly fixed on the sliding groove 301, and only can move transversely along the sliding groove 301, and cannot move in other directions. The pretightening force provided by the elastic member 533 can be automatically adjusted along with the change of the gap between the cross rod 201 and the sliding sleeve 531, so that the sliding sleeve 531 can be always jacked at the outer side of the sliding groove 301 in the sliding process, and the influence of assembly errors, machining errors and the like can be effectively compensated. The sliding groove 301 is matched with the fine adjustment sliding block 221, so that guiding and pre-tightening required during fine adjustment can be realized. The elastic member 533 is engaged with the sliding sleeve 531 to ensure stable sliding and pre-tightening.

In this embodiment, the elastic member 533 is a disc spring, and is composed of two sets of disc-shaped washers arranged face to face. In other embodiments, the elastic member 533 may also be a spring, an elastic pad, or other devices or components that can provide elastic force.

In this embodiment, the anti-vibration adjusting device includes two fine adjustment sliders 221 arranged in the transverse direction, so that the cross bar 201 and the sliding groove 301 can be fixed more firmly and have better sliding guidance. The V-shaped vernier slider 221 may also be self-centering during pretensioning. In other embodiments, a fewer or greater number of trim sliders 221 may be provided, such as one, three, or four trim sliders 221.

When adjusting, firstly, the sensor 211 is moved on the cross bar 201 by the rough adjusting slide block 203, and the position of the rough adjusting slide block 203 is roughly adjusted and fixed, thereby roughly adjusting the position of the sensor 211 fixed on the rough adjusting slide block 203. When moved to the approximate position, the coarse adjustment slide 203 is secured to the crossbar 201 by the locking screw 213. The position of crossbar 201, and thus sensor 211, is then fine tuned by moving crossbar 201 in the transverse direction by rotation of fine tuning knob 207.

Because the sensor 211 and the rough adjusting sliding block 201 are fixed on the cross bar 201, the cross bar 201 is fixed on the sliding groove 301 which is fixed with the device to be monitored 302, the sensor 211 is relatively fixed on the device to be monitored 302 and can only move transversely relative to the device to be monitored 302 through the transverse movement of the cross bar 201, and the sensor 211 is effectively prevented from shaking or deviating undesirably relative to the device to be monitored 302 in the operation process of the device to be monitored 302. Because the cross rod 201 is fixed through the sliding groove 301, an additional fixing or locking device is not needed, so that the adjustment is convenient to perform in the operation process of the device to be monitored 302, and the device to be monitored does not need to be stopped firstly for fixing.
