Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the protection scope of the present invention.
In actual production, packing materials are mostly provided in a roll shape, and are input into a packaging machine through unreeling, and the materials are packaged through various packaging processes. Under most circumstances, need control banded package material's horizontal and fore-and-aft position, realize the accurate shaping of package material in the follow-up packaging process, for example the fifty percent discount back edge flushes or the position accuracy, complete and the uniformity of extranal packing printed pattern to guarantee packaging quality, reduce the rejection rate. It is necessary to accurately control the lateral position at which the wrapping material is input.
The invention relates to an automatic deviation correcting device for a strip packing material, which comprises: two sets of deviation rectifying modules arranged oppositely and at least one sensor 6 connected to the PLC system.
As shown in fig. 1 and 2, 3 is a belt-shaped packing material, 1,1a and 2,2a are two sets of rollers disposed up and down on both sides of the packing material, and 6 is a correlation type photoelectric sensor. The two groups of rollers 1,1a and 2,2a have no driving power and can freely rotate around the axes thereof. Two gyro wheels of downside arrange along package material tangential direction, thereby two gyro wheels of upside can reciprocate under the cylinder effect and realize pressing from both sides tight or throw off to banded package material with two gyro wheels of downside. When the upper roller moves downwards and the lower roller clamps the strip packing material, the two rollers rotate freely under the action of friction force during the conveying of the packing material. Since the axes of the two pairs of rollers are at a small offset angle α to the direction of travel of the wrapping material, the direction of travel of the wrapping material is affected by the rollers and a lateral offset is produced, the magnitude and speed of the offset being dependent on the offset angle α, the desired error range and the speed of travel of the strip wrapping material. In operation, the sensor 6 detects the edge position of the packing material, judges the size of the transverse actual offset of the packing material, outputs an analog quantity signal, is processed by a PLC system, controls the rollers on the two sides of the upper surface to be clamped or separated with the rollers on the lower side, and when the upper and lower rollers are clamped, the belt-shaped packing material in transmission passes through two pairs of rollers 1,1a and 2,2a, and generates transverse displacement towards the side so as to correct the transverse position of the packing material. Until the sensor 6 detects a deviation of 0 or the opposite deviation value, the side roller is disengaged and the other side roller is clamped. The transverse position of the wrapping is thus always controlled within a small tolerance.
As shown in FIG. 4, the connecting plate 18 is a mounting and supporting part of the deviation correcting device, two ends of the two guide rods 11 are fixedly mounted on the connecting plate, the sliding blocks 19 are mounted on the two guide rods 11 in a penetrating manner, and in order to achieve the best using effect, the front side and the rear side of the deviation correcting device can be respectively provided with a roller 37 for the strip packing material to pass through.
One end of the screw rod 20 is fixedly connected with the knob I15, as shown in figures 3, 5 and 6, the middle part of the screw rod passes through a hole of the guide block 30 fixed on the connecting plate 18, the positioning ring 36 is fixed on the screw rod 20 by a screw, so that the screw rod 20 can only rotate and cannot axially move, and a wave-shaped gasket 27 is arranged between the positioning ring 36 and the guide block 30 in order to reduce the gap; the nut 12 is fixed on the sliding block 19 by a screw 28, the screw rod 20 penetrates through the nut 12 through threaded connection, and the screw rod 20 is driven to rotate by rotating the knob I15, so that the nut 12 is driven to drive the sliding block 19 to move along the axial direction of the two guide rods 11. The knob i 15 can thus adjust the lateral position of the slide 19 relative to the transport direction of the wrapping material. Further, the sensor 6 is fixed to the slider 19 via a bent plate 29, and the nut 12 is fixed to an end surface of the slider 19 with a screw 28.
As shown in fig. 6 and 7, the upper roller mechanism includes rollers 1, 2, roller brackets 7, 8, and a cylinder 9, the roller 1 is mounted on the roller bracket 7 through a bearing 10 and a screw 13, and the roller 1 can freely rotate around its axis.

One end of the tension spring 21 is fixed on the mounting frame 16 through a hanging spring nail 22, and the other end is fixed on the roller bracket 7 through a hanging spring nail. Therefore, the single-acting cylinder 9 drives the roller bracket 7 to drive the roller 1 to move downwards along the guide post 14 when the PLC control solenoid valve is connected with an air source to act, and drives the roller 1 and the roller bracket 7 to move upwards together for resetting through the tension spring 21 when the air source is cut off. The roller 2 is mounted on the roller support 8 through a bearing 35 and a screw, and the roller 2 can freely rotate around the axis of the roller. The roller support 8 is fixed to the mounting frame 16 by screws 32.
The bottom of the mounting frame 16 is provided with a positioning pin 23, and the mounting frame 16 is fixed on the slide block 19 through a screw 24 and the positioning pin 23. The mounting bracket 16 has a large clearance for the holes in which the screws 24 are mounted. By loosening the screws 24, the entire mounting bracket part can be turned a slight angle around the positioning pin 23. The bottom position of the side surface of the mounting frame 16 is provided with a positioning block by a screw 25, and a groove on the positioning block 34 is matched with the positioning pin 4 arranged on the sliding block 19. When mounting frame 16 is mounted on slide 19, first of all pins 23, 4 are engaged and finally screws 24 are locked. The inclination angle of the mounting frame 16 and the rollers 1 and 1a relative to the sliding block, namely the angle alpha in fig. 2, can be changed by changing the position of the groove on the positioning block 34 under different working conditions.
As shown in figure 8, the bottom of the sliding block is in threaded connection with a locking bolt 31, the end part of the locking bolt penetrates through the sliding block and then abuts against the guide rod 11, the end parts of the locking bolt 31 are respectively provided with a knob II 33, the sliding block is finely adjusted through a knob I15, two rows of packing materials in conveying are changed to the required central positions, and finally the two rows of packing materials are locked through the knob II 33, so that the reliability in working is kept.
