Description

Technical field:

[0001] The utility model relates to the technical field of emulsion explosive conveying equipment, in particular to an emulsion explosive packaging box sub-box conveying system. Background technology:

[0002] Emulsion explosives are a kind of water-in-oil type latex explosives that are formed by uniformly dispersing droplets of aqueous solution of oxidant salts in an oil phase continuous medium containing porous substances such as dispersed bubbles or hollow glass microspheres with the help of emulsifiers. In order to meet the market demand for emulsion explosives of different specifications, when two different specifications of emulsion explosive rolls are produced and packaged in boxes of different sizes, a conveyor is required to transport the boxes to the loading area.

[0003] The current transportation method is: two different specifications of emulsion explosive packaging boxes are transported at intervals using the same belt conveyor. When they are transported to the terminal loading point, the staff will sort the two sizes of packaging boxes on the belt conveyor and load them separately. This transportation method not only requires staff to carry and load, but also requires a waste of energy for sorting, which is labor-intensive and has high labor costs, affecting the overall loading efficiency.

[0004] Another way of conveying is to introduce industrial robots. An industrial robot is installed at the end of the belt conveyor and the industrial robot is used for loading. Although this helps to improve loading efficiency, it can only solve the loading of one specification of products. The packaging boxes of another specification of products on the belt conveyor still need manual assistance for sorting and loading. If multiple industrial robots are introduced, the price will be expensive and the cost will be high. Utility model content:

[0024] like Figures 1 to 5 As shown, this embodiment provides an emulsion explosive packaging box conveying system, which includes an industrial robot 10, which also includes a box input roller conveyor 1, a first transition roller conveyor 2, two parallel box separation roller conveyors 4, a second transition roller conveyor 5 and a box output roller conveyor 7 connected in sequence end to end; the box input roller conveyor 1 continuously conveys the spaced packaging boxes toward the first transition roller conveyor 2, including two packaging boxes of different specifications and sizes, and each adjacent two packaging boxes are spaced a distance apart, and the packaging boxes on the box input roller conveyor 1 are fed into one side of the first transition roller conveyor 2.

[0025] A box separation mechanism 3 is installed on one end of the first transition roller conveyor 2 adjacent to the box input roller conveyor 1, and the box separation mechanism 3 includes a bracket 3.1, a limit plate 3.5 and a drive cylinder 3.7; a bracket 3.1 is connected to the frame of the first transition roller conveyor 2, and a crossbeam 3.2 is connected to the bracket 3.1 through a traction mechanism 3.9, and the crossbeam 3.2 moves up and down along the bracket 3.1; a connecting plate 3.3 is fixed to the bottom end of the crossbeam 3.2, and a travel switch 3.4 is fixed on the back of the connecting plate 3.3. A swinging limit plate 3.5 is hinged on the front of the connecting plate 3.3, and the back of the limit plate 3.5 is connected to the contact of the travel switch 3.4 through a connecting rod 3.6; a long hole 3.3.1 is opened on the connecting plate 3.3 along the length direction of the beam 3.2, and the connecting plate 3.3 is fixedly connected to the beam 3.2 by passing a screw 3.12 through the long hole 3.3.1; the left and right position of the connecting plate 3.3 can be adjusted along the long hole 3.3.1, and then the position of the limit plate 3.5 can be adjusted to meet actual production needs.

[0026] A driving cylinder 3.7 is fixed on the bracket 3.1 at the front of the limit plate 3.5. The driving cylinder 3.7 is arranged parallel to the crossbeam 3.2, and a box-dividing push plate 3.8 is fixed to the telescopic end of the driving cylinder 3.7; the travel switch 3.4 is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the electromagnetic control reversing valve on the oil circuit of the driving cylinder 3.7.

[0027] The front of the limit plate 3.5 faces the direction in which the packaging boxes are delivered. The packaging boxes of small specifications will pass directly under the limit plate 3.5, while the packaging boxes of larger specifications will touch the limit plate 3.5. The limit plate 3.5 triggers the travel switch 3.4 through the connecting rod 3.6. The travel switch 3.4 feeds back the signal to the controller. The controller controls the electromagnetic control reversing valve on the oil circuit of the drive cylinder 3.7 to move, thereby controlling the drive cylinder 3.7 to move.

When the drive cylinder 3.7 moves and retracts, it drives the box separation push plate 3.8 to move, and the larger packaging boxes are pushed into the box separation push plate 3.8. The box is pushed to the other side of the first transition roller conveyor 2. An induction switch is provided on the frame at the other side of the first transition roller conveyor 2. When the pushed box is sensed, the feedback controller controls the driving cylinder 3.7 to reset. In this way, the two boxes of different specifications can be effectively sorted and conveyed separately on the first transition roller conveyor 2. The two boxes of different specifications after sorting are sent to the corresponding box separation roller conveyor 4, which is beneficial to reduce the labor intensity of sorting of the staff. Moreover, under the condition of equal output, compared with using one conveyor for transportation, separate transportation is beneficial to shorten the transportation distance and improve efficiency.

The guide sleeve 3.11 is fixedly connected to the box push plate 3.8. Under the matching guidance of the guide sleeve 3.11 and the guide rod 3.10, the driving cylinder 3.7 drives the box push plate 3.8 to move more smoothly.

Two boxes of different specifications are sent to the box closing mechanism 6 through the two box separation roller conveyors 4. The two box separation roller conveyors 4 have the same running speed. Therefore, the boxes of two specifications are also sent to the box closing mechanism 6 at intervals. An industrial robot 10 is installed at the end of the box output roller conveyor 7. A first induction switch 8 is installed on the side of the second transition roller conveyor 5 between one of the box separation roller conveyors 4 and the box closing mechanism 6.

Large-sized packaging boxes are stacked together at the designated position. In this way, packaging boxes of two specifications can be stacked separately. A corresponding induction switch is installed at the end unloading position of the box output roller conveyor 7. When the packaging box is transported to this position along the box output roller conveyor 7, the signal is fed back to the controller, and the box output roller conveyor 7 is controlled by the controller to stop, so that the industrial robot 10 can grab the packaging box for palletizing; through the cooperation of the box closing mechanism 6 and the box output roller conveyor 7, the packaging boxes of two specifications can be transported to the same grabbing position of the industrial robot 10.

[0031] The box closing mechanism 6 includes a gantry 6.1 installed between the two sides of the second transition roller conveyor 5. A blocking rod 6.2 opposite to one of the box separation roller conveyors 4 is fixed on the frame of the second transition roller conveyor 5 to block the packaging boxes of larger specifications, so that the box closing mechanism 6 can push them; sliding rods 6.3 parallel to each other are fixed on the gantry 6.1 above the blocking rod 6.2, and sliding sleeves 6.4 are slidingly provided on the sliding rods 6.3. A box closing plate 6.5 is fixed between the two sliding sleeves 6.4. During the movement of the box closing plate 6.5, the sliding sleeve 6.4 moves along the sliding rod 6.3, which plays an effective guiding role and ensures the stable operation of the box closing plate 6.5; a telescopic Cylinder 6.6, the telescopic end of the telescopic cylinder 6.6 is fixedly connected to the box closing plate 6.5; the initial state of the telescopic cylinder 6.6 is in the extended state. When a larger-sized packaging box triggers the first induction switch 8, the signal is fed back to the controller. At the same time, the packaging box is blocked and limited by the blocking rod 6.2. The telescopic cylinder 6.6 is controlled to contract by the controller. The telescopic cylinder 6.6 drives the box closing plate 6.5 to push the packaging box to the other side of the second transition roller conveyor 5, so as to facilitate the subsequent delivery to the box output roller conveyor 7; an induction switch is also installed on the frame on the other side of the second transition roller conveyor 5. When the packaging box being pushed over is sensed, the signal is fed back to the controller, and the telescopic cylinder 6.6 is controlled by the controller to reset.
