Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco packaging, in particular to a feeding equipment. BACKGROUND

[0002] In cigarette production, a cigarette making machine rolls tobacco and cigarette paper together into a cigarette, and cuts and processes it to obtain the final product, and configures a filter rod at one end of the cigarette for filtering and reducing harmful substances in the smoke. At present, the feeding of filter rods is mostly carried out manually. Before feeding, the filter rods are vertically placed in a packaging box, as shown in FIG. 1, the packaging box is flat and the top of the packaging box is open, and the filter rods abut against each other. One side of the packaging box is a foldable cover plate, and the cover plate can be folded to the open state of the side of the packaging box. The cover plate has foldable ears at both ends, and when the cover plate is folded to the closed state of the side of the packaging box, the ears are inserted into the side wall of the packaging box.

The photoelectric sensors detect the position of the packaging box during the conveying process, and when the position of the packaging box cannot be detected, an upper feeding signal is sent to the upper feeding manipulator 4, so that the upper feeding manipulator 4 feeds the feeding conveying mechanism 3.

[0078] Further, a positioning plate 32 is slidably arranged on one side of the feeding conveying mechanism 3 corresponding to each position where the packaging box needs to stop, and the positioning plate 32 slides along a horizontal direction perpendicular to the conveying direction of the packaging box. The position of the packaging box is detected by the photoelectric sensor, and then the corresponding positioning plate 32 is controlled to extend to block the packaging box, so as to realize accurate positioning of the packaging box.

[0081] Further, one of the first positioning member 511 or the second positioning member 512 can slide along a horizontal direction perpendicular to the conveying direction of the packaging box, so as to realize compact positioning of the packaging box when the conveying of the packaging box is stopped. Alternatively, the first positioning member 511 and the second positioning member 512 can be relatively movable. Specifically, in the embodiment, the first positioning member 511 is fixedly connected to the feeding conveying mechanism 3, and the second positioning member 512 is slidably connected to the feeding conveying mechanism 3.

[0082] With reference to Figure 3 , Figure 6 and Figure 7The uncovering base plate 52 is vertically arranged, the uncovering base plate 52 is arranged above the second positioning member 512, the surface of the uncovering base plate 52 is parallel to the conveying direction of the packaging box, the uncovering base plate 52 is slidingly connected to the rack 2, and the uncovering base plate 52 slides in the vertical direction. When the uncovering base plate 52 slides, the uncovering base plate 52 moves towards or away from the packaging box. Alternatively, the uncovering base plate 52 can be installed on the mechanical arm, and the uncovering base plate 52 is driven by the mechanical arm to move towards or away from the packaging box.

[0083] Further, the adsorption assembly 53 comprises an adsorption plate 531 and a first suction cup 532, the adsorption plate 531 is horizontally arranged, the adsorption plate 531 is slidingly arranged on the uncovering base plate 52, the adsorption plate 531 slides in the vertical direction, and a plurality of first suction cups 532 are fixedly arranged at the bottom of the adsorption plate 531.

[0087] When the packaging box is conveyed to the lower side of the adsorption plate 531, the conveying of the packaging box is stopped, and the packaging box is tightly pressed to the first positioning member 511 by the second positioning member 512, so that the second positioning member 512 covers the opening of the packaging box, the opening of the packaging box is sealed, and the filter rod is not easy to fall off. Then, the adsorption plate 531 drives the first suction cup 532 to descend, the first suction cup 532 adsorbs the cover plate of the packaging box, and then the adsorption plate 531 is controlled to move upwards, so that the cover plate of the packaging box is folded upwards, and a gap for the plug plate 542 to insert is formed between the cover plate and the packaging box.

[0088] The plug-in plate 542 is slid into the gap, and the cover substrate 52 drives the plug-in plate 542 to move upwards, so that the cover plate continues to flip away from the packaging box, and the cover plate is opened. During the upward movement of the plug-in plate 542, the pressing plate 543 below the plug-in plate 542 slides towards the packaging box, further flips the cover plate away from the packaging box, so that the cover plate of the packaging box is not easily flipped in the opposite direction, and the top of the packaging box is always in an open state.

[0089] It should be noted that the cover opening substrate 52 can also be horizontally arranged, and the cover opening substrate 52 can slide in the horizontal direction.

[0092] Referring to Figure 5 and Figure 8 , the stop rod 31 is fixedly arranged at the position close to the rejection mechanism 6 on the side of the feeding and conveying mechanism 3, and is arranged along the conveying direction of the feeding and conveying mechanism 3. When the packaging box is conveyed to below the rejection mechanism 6, the stop rod 31 can further open the cover plate that has been opened on the packaging box. At this time, the feeding and conveying mechanism 3 stops conveying the packaging box, and the detection camera 62 takes a picture of the filter rod for detection. If it is detected that the filter rod is horizontally arranged, the mechanical arm 61 drives the second suction plate 63 to suck the disordered filter rod and put it into the recycling box after suction, so as to reject the disordered filter rod.
