[0003] In order to ensure that the material is fed in the right direction, avoid quality problems such as identification position deviation and information loss caused by direction deviation, some existing automatic marking machines use feeding equipment with detection function to judge the direction of the material.

After the material is conveyed to the marking station by the belt conveyor one by one, the axial positioning is realized by the positioning block driven by the cylinder. After the marking head completes the identification processing, it is pushed to the code reading station for optical character recognition or two-dimensional code decoding by the translation cylinder one by one. Finally, the unloading is completed by the inclined slide or mechanical arm.

The material discharging push plate 2010 can move in the horizontal longitudinal direction. A moving plate 2011 is arranged directly below the material storing area 292 of the material receiving tray 29. The moving plate 2011 can move in the horizontal longitudinal direction. The material discharging push plate 2010 can push the material in the material storing area 292 to fall onto the moving plate 2011. A multi-cell material tray 2012 is installed on the moving plate 2011. The multi-cell material tray 2012 comprises a plurality of rectangular material cells 20121 arranged in the horizontal longitudinal direction. The length direction of each material cell 20121 is arranged in the horizontal transverse direction.

[0049] In this embodiment, the movement of the storage mold 22, the material discharging gripper 281, the material discharging push plate 2010 and the moving plate 2011 can all use common moving mechanisms, such as a slider rail mechanism or a screw nut mechanism.

[0050] Working process: The bulk material first enters the feeding machine 1012, is arranged in order after being arranged by the feeding machine 1012, is transported to the discharging end in the direction perpendicular to the conveying direction of the conveying belt one 11, and is then transferred to the conveying belt one 11 and is transported to the multi-station turntable 12 in the radial direction of the multi-station turntable 12.

[0051] During the conveying process of the conveying belt one 11, the upside-down removal device starts to work. The upside-down removal plate 1013 reciprocates along the direction perpendicular to the conveying direction of the conveying belt one 11. The light-transmitting groove 10131 on the plate surface cooperates with the reflective photoelectric sensor 1015 on both sides to determine whether the material is in an upside-down state by detecting the change of the light blocked by the material. If the upside-down material is detected, the upside-down removal plate 1013 will push it to the opposite removal box 1014, so that it falls into the box through the slot 10141, avoiding the upside-down material from entering the subsequent process.

[0052] The qualified material after screening continues to be conveyed by the conveying belt one 11, and finally enters the placement groove 131 of the material placement mold 13 on the upper end surface of the multi-station turntable 12. The placement groove 131 of the material placement mold 13 is arranged along the radial direction of the multi-station turntable 12 and passes through the center, which matches the conveying direction of the conveying belt one 11, and can ensure accurate positioning of the material. The motor one 17 drives the multi-station turntable 12 to rotate intermittently around the axis, and the material placement mold 13 is sequentially transferred to the next station, realizing continuous feeding.

[0053] When the material is transferred to the front-back detection device 14 with the multi-station turntable 12, the camera 141 of the front-back detection device 14 collects the image of the material, and the direction of the material is recognized by the pre-set front-back feature.

[0054] The motor two 15013 of the material transfer device 15 drives the swing rod 155 to rotate, and through the sliding of the sliding block in the inverted U-shaped sliding groove 154 and the sliding groove 156, drives the vertical sliding rod 158 to ascend and descend along the vertical sliding rail 15014, realizing the vertical action of the feeding grabbing part 151; at the same time, the transverse sliding plate 15010 slides along the transverse sliding rail 15011, driving the feeding grabbing part 151 to move along the radial direction of the multi-station turntable 12. The two spaced feeding grabbing parts 151 synchronously clamp and place the material, one by one, from the multi-station turntable 12 to the horizontal rotating table 161, and then to the conveying belt two 21. If the material is in reverse direction, the motor three 163 drives the horizontal rotating table 161 to rotate 90° to complete the correction; if the material is in forward direction, the motor three 163 does not act. In this way, the forward material after correction or direct transfer can be placed on the conveying belt two 21.

[0055] After the material is conveyed to the conveying belt two 21, the conveying belt two 21 conveys the single-column material along the horizontal transverse direction, and the end thereof is aligned with the storage mold 22. The storage mold 22 is provided with a plurality of storage grooves 221 arranged along the horizontal longitudinal direction, and the storage grooves 221 extend along the horizontal transverse direction and are provided with openings 222 at one end close to the conveying belt two 21. The storage mold 22 moves along the horizontal longitudinal direction, and the openings 222 of the storage grooves 221 are aligned with the end of the conveying belt two 21 in sequence, so that the materials enter different storage grooves 221 one by one, completing batch storage.

[0056] When all the storage slots 221 of the storage mold 22 are filled with materials, the feeding gripper 23 above it is activated. The feeding gripper 231 descends in the vertical direction and clamps all the materials in the storage slots 221. The feeding gripper 231 moves horizontally to the upper side of the four-station turntable 24, aligns with the clamping slot 251 of the clamping mold 25 below, and then descends in the vertical direction to synchronously put the materials into the clamping slot 251, completing the feeding.

[0057] The four-station turntable 24 rotates by 90° around the axis, so that the clamping mold 25 filled with materials moves to the position below the marking device 26. The laser generator 261 of the marking device 26 performs laser marking on the materials in the clamping mold 25, while the empty clamping mold 25 moves to the feeding position to wait for the next feeding.

[0058] The turntable rotates by 90° again, so that the materials after marking move to the position below the code reading device 27. The code reader 271 identifies the marks to determine whether the materials are qualified, i.e., to distinguish between good products and defective products.

[0059] The turntable continues to rotate by 90°, so that the materials after code reading move to the position below the discharging gripper 28.

[0060] The discharging gripper 281 of the discharging gripper 28 descends in the vertical direction, clamps the materials, and then moves in the horizontal direction according to the code reading result to move the materials to the corresponding area of the receiving tray 29.

[0061] After the good products enter the good product slot 2911, the good product push plate 2913 moves horizontally under the drive of the good product cylinder push rod 2916 to push the good products to the storage area 292 for temporary storage.

[0062] After the defective products enter the defective product slot 2912, the defective product push plate 2914 moves horizontally under the drive of the defective product cylinder push rod 2917 to push the defective products into the defective product slot 2912 for temporary storage. If the defective product slot 2912 is full, the contact sensor 2915 near the material distribution area 291 triggers an alarm to remind the staff to clean it in time.

[0063] When the good products in the storage area 292 accumulate to a certain amount, the discharging push plate 2010 above it moves horizontally to push the materials to the moving tray 2011 below. The moving tray 2011 moves horizontally to receive the materials with the multi-slot tray 2012 above it, so that the materials fall into the corresponding slots 20121 in an orderly manner, completing the final storage.

[0064] In this embodiment, the four-station turntable 24 continuously rotates, and the feeding, marking, code reading, and discharging processes are performed synchronously to form a continuous closed loop, greatly improving the processing efficiency and production stability of batch materials.
