Ltd. The invention relates to handling, transport and warehousing operations and may be used in mining. A device for unpacking bags of bulk material is known, comprising a housing, a bag feeding mechanism and a cutting mechanism 1. However, this device is not suitable for unpacking a bag package. It is also known a device for unloading bags with bulk material, comprising a table for feeding a bag package, horizontal guides, a carriage mounted therein with grippers for moving the bag layer, a cutting mechanism, a vibrating channel, a device for removing empty bags and a hopper for bulk materials. However, this device is unreliable in operation, since it does not exclude the fall of bags from a height, which is impossible when unloading explosives (BB). The aim of the invention is to increase the reliability of operation. The goal is achieved in that the device for unpacking bags with bulk material, contains a table for supplying a bag package, horizontal guides, a carriage mounted in them with grippers for moving the bag layer, a cutting mechanism, a vibratory tray, a device for removing empty bags and a bunker bulk material, each gripper for moving the layer of bags consists of a hydraulic cylinder mounted on the carriage, a pin with a slot and placed in the last pivotally connected arms GOVERNMENTAL on the cylinder rod, means for removal of emptied bags is designed as a curved plate arranged between the grippers on the carriage, and rezhushy mechanism is a floating disc knives mounted to vibrating tray. FIG. 1 shows a device for unloading bags, a general view; in fig. 2 - rastarivaniya node; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - carriage with grippers before putting them inside the bags; in fig. 5 - the same, when moving a layer of bags; in fig. 6 is a section BB in FIG. five; in fig. 7 is a view of B in FIG. 6. The bag unloading device consists of a bag disassembling device, including a lifting table 1, on which bag 2 is placed, carriages 3 with grippers and accessories for lifting bags, floating knives 4 and a perforated vibrating channel 5 passing into the bag 6 discharge tray. The knives 4 are rigidly seated on a rotating crankshaft 7, due to which they acquire translational motion in the direction opposite to the movement of the bag layer. From below, under the knives 4 and the vibrating tray 5, the storage hopper 8 is mounted, and from above a sealed casing 9 for suction of air contaminated with dust from an explosive. The packages 2 are installed on the lifting table 1 by means of a suspended crane 10 and a fork 11. Each grip consists of paired flat pins 12, in which along the slots 13 in them are moved by means of hydraulic cylinders 14 pivotally connected levers 15. On the cases of hydraulic cylinders 14 fixed vibrator 16, included in the work at the time of entry of the grips in the layer of bags. Between each pair of paired flat pins 12, a device for removing bags is located, consisting of hydraulic cylinders 17, on the rod of which shaped figure plates 18 are fixed. On flat pins x 12, a restrictive casing 19 is fixed, with dimensions for the layer of bags in package 2. The device works as follows. Installing using a suspended crane 10 and fork 11 package 2 on the lifting table. 1, lift it up until the flat pins 12 are fully inserted into the bags of the upper layer. Following this, when the vibrator 16 is turned on, the hydraulic cylinders 14 disengage the levers 15 and lower the table 1 until the captured layer of bags separates from the rest of the bag 2. Next, the captured layer of bags, moving toward the vibrating tray 5, gradually finds on the blades 4, which in its upper position when moving in the opposite direction, cuts are made in the lower part of the bag layer, through which the explosives are released into the hopper 8. Above the vibrating channel 5, the arms 15 are folded again, and the released bags are shifted by means of pick-up devices vibrating tray to 5, where the final emptying them from explosives. At the end of the vibrating tray 5, there is a tray 6, through which the vacated bags are sent to the trailer or container to collect them. With the carriage 3 returning to its original position, lifting the table 1 begins the cycle of unloading the next layer of bags. The device operates in automatic mode with the help of limit switches, at the right moment giving the appropriate command to the mechanisms to stop or start a particular operation. This device for unloading allows bag unloading of bags with explosives formed according to any scheme, since the grippers that are part of the device detach the entire layer from the bag at once, and therefore the scheme in which the bags are laid in the layer does not matter. In addition, the disbanding of bags with any arrangement of bags in the layer makes it possible to use conventional standard flat pallets. This, in turn, makes it possible to ensure that the SO / o-ny level of mechanization of cargo handling and charging explosives, starting from the manufacturer, with a reduction in labor costs for the processing of explosives.
