The ring member 103 is sleeved outside the turntable bearing 116, a groove for placing the roller/ball is formed in the inner wall of the ring member close to the turntable bearing 116, the roller/ball 201 for reducing the rotation resistance of the moving frame 111 is arranged in the groove, and the upper cover 114 is pressed on the roller/ball 201 to obtain the supporting force in the z direction; disc member 105 is secured over ring member 103 and may be secured to a fixed wall/bracket or to a movable assembly.
The distance between the first guide plate 101 and the second guide plate 112 in the embodiment of the invention can be adjusted by the adjusting screws 118 of the first guide plate 101 and the second guide plate 112, and the adjusted distance between the first guide plate 101 and the second guide plate 112 is equal to the distance of the y-direction dimension of the packing box. The code spraying machine is generally composed of a code spraying machine main body and a code spraying terminal, and the code scanning machine is generally composed of a computer main body and a code scanning terminal; the code spraying machine main body of the embodiment of the invention is arranged outside the equipment, and the code spraying port 110 is arranged on the connecting piece; the computer body is mounted outside the apparatus and the scanning head 102 is secured to the z-shaped connector by the z-shaped connector.
In the implementation, the packing box is placed on a production line, the production line moves from x positive direction to x negative direction, and the placement direction of the packing box deviates from the x direction by a small angle; the packing box is firstly contacted with one guide plate, and the rotating frame is driven to rotate around the rotating shaft through the guide plate; as the pack continues to move, the other guide plate also contacts the pack; as the contact area between the packing box and the two guide plates is increased, the guide plates are completely attached to the packing box; the rotating frame drives the code spraying machine and the code scanning machine to adjust positions through the connecting piece, and the rotating frame is always perpendicular to the position of the guide plate under the action of the rotating frame; in practical implementation, the positions of the code spraying machine and the code scanning machine in the y direction can be adjusted according to the code spraying position requirement.
Embodiment two: fig. 3 shows a bottom view of an embodiment of the present invention. In particular, in order to increase the smoothness of the contact between the guide plate and the package, a guide arc surface is provided on one end of the first guide plate 101 and the second guide plate 112 facing the x-direction; when the packing box contacts with the guide plate, the packing box contacts with the guide arc surface first and gradually transits to the plane through the guide arc surface.
Embodiment III: in the implementation, the packing box is firstly contacted with one guide plate and then contacted with the other guide plate; at this time, if the angle of the rotating frame is not rotated to the 4 proper positions, there may be a case where the length of the contact point connecting line between the packing box and the two guide plates is longer than the distance between the first guide plate and the second guide plate, and at this time, the rotation of the rotating frame may generate a large resistance, and may not be smoothly rotated. In order to avoid this, in the implementation, one of the guide plates may be designed to be elastically fixed, in the second embodiment, the first guide plate 101 and the rotating frame 111 are connected and fixed by using a screw 108, the second guide plate 112 and the rotating frame 111 are connected by using a bolt 108 which is not fully threaded, and the periphery of the second guide plate is sleeved with a spring 301; when encountering resistance, the second guide plate can be compressed, so that the distance between the first guide plate and the second guide plate is increased, and the rotating frame can rotate under the condition of small resistance; when the resistance disappears, the spring resets the second guide plate.
Embodiment four: in practice, the position of the pack in the y direction (position in the y direction of the conveyor belt) will generally vary, and in order to make the apparatus suitable for the production of the line, a guide pulley 106 and a guide rail 109 are provided above the mobile frame 117; the slide rail 109 is arranged along the y direction, and the pulley 106 is clamped in a groove of the guide slide rail 109 under the self weight of the equipment through the connecting piece 107; in order to increase the stability of the device when moving along the y direction, the embodiment of the invention is provided with two groups of guide pulleys and guide sliding rails.
Fifth embodiment: FIG. 4 illustrates a top view of a dynamically adjusted automatic code spraying and scanning machine in which the guide rail and disk members are hidden, in accordance with an embodiment of the present invention. In particular, if the rotation angle of the moving frame 111 is too large, the packing box may collide with the outer side surface of the guide plate directly, and the inner side surface of the guide plate cannot be used for adjusting the angle of the moving frame 111, so that the equipment is failed.
The fifth rotary reset device of the embodiment of the invention is a torsion spring 401, one end of the torsion spring 401 is fixed on the upper cover 114 of the rotating shaft, and the other end is fixed on the component 104 of the movable frame; when the rotating frame 111 rotates, the torsion spring 401 is twisted to deform and store energy; when the package passes through the device, the resistance disappears, and the torsion spring 401 returns to its original shape, driving the turret to reset.
Example six: FIG. 5 illustrates a front view of a dynamically adjusted automatic code spraying and scanning machine in accordance with an embodiment of the present invention. The guide plate structures of embodiments 1 to 5 mainly solve the problems that the axis direction of the packing box is not parallel to the x direction and the packing box has a position offset in the y direction, and in specific implementation, the heights of the top surfaces of different packing boxes in the z direction are different due to the processing errors of the packing boxes. Because the spraying wharf of the code spraying machine and the scanning wharf of the code scanning machine have the most suitable working distance (the distance from the top surface of the packaging box), in order to ensure that the spraying wharf and the scanning wharf can work at the most suitable working distance, the distance between the spraying wharf and the scanning wharf and the surface of the packaging box needs to be adjusted in real time.
In the embodiment of the invention, a fixing frame is arranged, a z-direction adjusting mechanism and a z-direction buffer mechanism are arranged above the fixing frame, and a horizontal guide plate is arranged below the fixing frame. The z-direction adjusting mechanism can adjust the z-position of the fixing frame to adapt to packaging boxes with different sizes, and comprises a screw and nut combination 501; the z-direction buffer device is used for providing a certain buffer force to avoid damage to the spraying wharf and the scanning wharf caused by excessive vibration, and comprises a screw nut combination 502 and a buffer spring 503; the middle part of the horizontal guide plate is hollowed, the spraying wharf 110 and the sweeping wharf 102 are arranged in the middle part of the horizontal guide plate 504, and the horizontal guide plate 504 is contacted with the upper surface of the packing box; because the positions of the spraying wharf 110, the sweeping wharf 102 and the horizontal guide plates 504 are relatively fixed, the horizontal guide plates 504 are attached to the upper surface of each packing box, so that the distance between the spraying wharf 110 and the sweeping wharf 102 and the upper surface of each packing box is relatively fixed during operation, and the most suitable working distance between the spraying wharf 110 and the sweeping wharf 102 during each operation can be ensured by setting the relative positions of the spraying wharf 110, the sweeping wharf 102 and the horizontal guide plates.
Embodiment seven: in order to reduce the impact force generated during the contact between the horizontal guide plate and the packing box, a guide arc surface is arranged in the x positive direction of the horizontal guide plate, and the upper surface of the packing box is firstly contacted with the guide arc surface and then gradually transits to the plane of the horizontal guide plate.
The control mode of the code spraying machine and the code scanning machine can realize position control through a mode of combining a contact sensor and a PLC. A first sensor 302, a second sensor 303, a third sensor 304 and a fourth sensor 305 are arranged in the x direction of the horizontal guide plate, wherein the first sensor 302 and the second sensor 303 are used for controlling the work of the code scanner; the first sensor 302, the second sensor 303, the third sensor 304 and the fourth sensor 305 are connected to the PLC; the first sensor 302 and the second sensor 303 are sequentially arranged in the x direction, when the first sensor 302 and the second sensor 303 are blocked and triggered by the packaging box, a PLC sends an instruction to the code spraying machine to trigger the code spraying machine to act once, and the position of the code spraying machine in the x direction of the packaging box can be controlled by controlling the distance between the first sensor 302 and the second sensor 303; similarly, by controlling the distance between the third sensor 304 and the fourth sensor 305, the PLC can send a signal to trigger the scanning head to perform a single action when the code is being scanned underneath the scanning head.
Because the embodiment of the invention mainly focuses on the design of the mechanical structure, the control modes of the code spraying machine and the code scanning machine are not described in more detail.
In the implementation, the packing box is conveyed from the positive direction to the negative direction through the conveyor belt, if the packing box has an angle deviation with the x direction, one guide plate can be firstly touched in the conveying process of the conveyor belt, and the rotating frame is driven to rotate through the guide plate; then the other end of the guide plate contacts the other side surface of the packing box, and finally the two guide plates are clung to the two sides of the packing box; meanwhile, when the first sensor and the second sensor are triggered simultaneously, the ink jet printer is activated to act once; when the third sensor and the fourth sensor are triggered simultaneously, the code scanning machine is activated once; when the package flows through the device, the turret resets.
The dynamic adjustment automatic code spraying and sweeping machine provided by the embodiment of the invention mainly realizes the function of positioning code spraying and sweeping by using a mechanical structure, and has the characteristics of lower cost, low realization difficulty, high working speed and the like compared with computer control, and has good practicability.
The dynamic adjustment automatic code spraying and scanning machine provided by the embodiment of the invention is described in detail, and specific examples are applied to illustrate the principle and the implementation of the invention, and the description of the above embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
