Description

Technical Field

[0001] The utility model relates to a device for stacking and conveying cigarette strips layer by layer. Background Art

[0002] The cigarette cartons are formed by arranging and packaging multiple boxes of cigarettes, and after being sorted, the cigarette cartons are transported by a conveying mechanism to a packaging mechanism for film packaging to form a finished product.

The stacking method is generally from bottom to top, that is, a stacking cavity is formed and the cigarette cartons are freely dropped inside for stacking, which is prone to scattering. At this time, there is a risk of damaging the cigarette packaging by flattening through compression in the cavity, which is not conducive to ensuring quality and the smooth progress of subsequent packaging work, and the efficiency is reduced, which needs to be improved urgently.

DETAILED DESCRIPTION

[0022] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0023] like Figures 1 to 6 As shown, the device for stacking and conveying cigarette strips upward layer by layer comprises a stacking frame 1, a transition conveyor belt 3 for connecting with the cigarette strip input conveyor belt 2 is arranged at the bottom of the stacking frame, two groups of lifting rollers 4 for circulated lifting of cigarette strips are symmetrically arranged on both sides of the transition conveyor belt, a plurality of supporting rods 5 are evenly distributed along the circumference of the outer circumference of the lifting rollers, and a pressing plate 6 for pressing on the cigarette strips is arranged above the lifting rollers, and the side ends of the pressing plates slide vertically through sliding columns 7 to be lifted as the cigarette strips 8 are stacked, a pushing frame 9 is slidably connected to the top of the stacking frame in the same direction as the cigarette strip conveying direction, a pushing cylinder 10 for horizontally pushing the pushing frame is fixedly arranged on the stacking frame, and a blocking cylinder 11 is provided on the stacking frame between the cigarette strip input conveyor belt and the transition conveyor belt, and a baffle 12 is fixedly connected to the lower end of the blocking cylinder.

[0024] In the embodiment of the utility model, the ends of the two lifting rollers are driven by a stepper motor to rotate step by step. As for the advancement distance of the blocking plate, it can be adjusted according to the induction of the sensor. It is a universal setting and will not be elaborated on here.

[0025] In the embodiment of the utility model, both pressure plates are strip-shaped and extend longitudinally, and a vertical adjustment plate 13 is fixed on the top of the pressure plate. A plurality of adjustment holes 14 are vertically spaced apart on the adjustment plate, and the adjustment plate is connected and fixed to a connecting plate 15 extending laterally outward. The outer end of the connecting plate is fixedly connected to a slider 16 that slides on a sliding column, and the sliding column is vertically fixedly connected to the stacking frame.

[0026] In the embodiment of the utility model, the stacking frame is provided with a partition 17 above the lifting roller, and a vertical groove 18 is vertically opened on the partition for vertical sliding of the connecting plate, and a clearance opening 33 is opened at the bottom of the partition for the support rod to rotate and make way. The clearance openings are arranged at intervals along the longitudinal length direction of the partition and correspond one-to-one to the support rod support sections.

[0027] In the embodiment of the utility model, the two partitions are hinged with buffer plates 19 on the cigarette output side. The buffer plates extend vertically and the outer sides of the top or bottom are connected to the hinged partitions via springs 20 to reset to a state perpendicular to the partitions. The springs extend obliquely toward the middle of the top or bottom of the partitions and are fixed to avoid hindering the lifting of the pressing plate and the connecting plate. When in use, when the cigarette cartons are stacked, they are pushed by the push rack and blocked by the two buffer plates to level the position to avoid skewed stacking and output. However, the resistance will be overcome by the thrust and unfolded, allowing the push rack to push the cigarette cartons to the next conveying process for packaging.

[0028] In the embodiment of the utility model, a plurality of support rods are evenly spaced along the longitudinal extension direction of the lifting roller, and the outer ends of the support rods are fixedly connected with support sections 21 for horizontally supporting cigarette strips, and the top of the support section and its connection with the support rod are both arc-shaped transitions.

[0029] In the embodiment of the utility model, the pushing frame includes a pushing seat 22 connected to the pushing cylinder, a vertically arranged lifting cylinder 23 is fixedly provided in the middle of the pushing seat, the lower end of the lifting cylinder piston rod passes through the pushing seat and is fixedly connected to a pushing handle 24, two vertically extending hollow guide columns 25 are symmetrically arranged on both sides of the lifting cylinder, and core columns 26 are slidably connected in the hollow guide columns. The lower ends of the core columns pass through the pushing seat and are fixedly connected to the pushing handle. After completing a pushing, the lifting cylinder moves the push handle up and retracts it, and then extends it again to move the push handle down into place after the pushing cylinder is longitudinally reset.

[0030] In the embodiment of the utility model, longitudinally extending guide rods 27 are fixedly provided on both lateral sides of the stacking frame, and the push seat is fixedly provided with a guide seat 28 sleeved on the guide rods to guide the sliding movement.

[0031] In the embodiment of the utility model, the transition conveyor belt is longitudinally extended with two groups, and a longitudinal sliding slide 29 is arranged between the two groups of transition conveyor belts. A vertical blocking plate 30 is fixedly connected to the upper end of the slide, and the lower end of the slide is slidably connected to a longitudinally extending slide rail 31 and driven to slide by a longitudinal cylinder 32.

[0032] The working principle of the embodiment of the utility model is as follows: first, the cigarettes are transported to the baffle plate through the cigarette input conveyor belt to be blocked, and then a few cigarettes are placed as the top layer according to the stacking and packaging needs, that is, the baffle plate moves up, and the baffle plate slides partially toward the output end with the slide seat to block the few cigarettes, and then the baffle plate moves down again to press or block the subsequent cigarettes, and then the two lifting rollers rotate one station, so that the supporting rod lifts the few cigarettes a distance away from the transition conveyor belt and the baffle plate, and then the baffle plate slides toward the output end with the slide seat to receive more cigarettes in the lower layer. That is, the baffle moves up to push the cigarette cartons to the position of the top blocking plate and then moves down, and then the second layer of cigarette cartons can be lifted up. At this time, the supporting rods that are top-connected to the first layer are displaced and detached from the cigarette cartons, so that the first layer of cigarette cartons fall on the second layer of cigarette cartons, and the next group of supporting rods support and lift the second layer of cigarette cartons. The horizontal height of the supporting section in each supporting state is consistent with the horizontal height of the receiving table at the output end to facilitate pushing out the material, and then multiple layers of cigarette cartons are stacked in this cycle. Finally, the pushing cylinder pushes the pushing rack to push the cigarette cartons out of the stacking chamber for subsequent packaging.

[0033] The present invention is not limited to the above-mentioned best implementation mode. Anyone can derive other various forms of cigarette cartons stacked upward layer by layer under the inspiration of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
