Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a material throwing device of a car loader, which comprises a rack 1, wherein two material throwing assemblies are arranged on the rack 1 and are distributed at intervals in parallel, the two material throwing assemblies are designed to be suitable for two mechanical arm stacking devices, each material throwing assembly is provided with a feeding conveyer belt 2 and a material throwing conveyer belt 3, and the output end of the feeding conveyer belt 2 is aligned and butted with the input end of the material throwing conveyer belt 3; during operation, materials enter from the input end of the feeding conveying belt 2 and are conveyed to the material throwing conveying belt 3 through conveying of the feeding conveying belt 2, in the working process, the feeding conveying belt 2 intermittently conveys the materials to adapt to the stacking and packing interval of the mechanical arm 4, the material throwing conveying belt 3 constantly moves at a constant speed to ensure sufficient material throwing power and conveying efficiency, and the conveying speed of the material throwing conveying belt 3 is higher than that of the feeding conveying belt 2, so that the material throwing conveying belt 3 can provide relatively constant throwing force, the problem that the material throwing requirement can be met only by accelerating to a certain degree due to intermittent conveying is solved, and the working efficiency is improved. Every the output of throwing material conveyer belt 3 is equipped with a mechanical arm 4, is equipped with the receiving port that is used for receiving throwing material conveyer belt 3 and throws the material on mechanical arm 4, is equipped with the feeding actuating mechanism that is used for driving feeding conveyer belt 2 motion and is used for driving throwing material actuating mechanism that throws material conveyer belt 3 motion on frame 1, is equipped with the control assembly of control feeding conveyer belt 2 action on frame 1, mainly is used for coordinating feeding conveyer belt 2 and mechanical arm 4 and matches each other, specifically, after mechanical arm 4 has received a material, mechanical arm 4 need move to the sign indicating number package position and carry out the sign indicating number package operation this moment, feeding conveyer belt 2 needs the temporary stop motion this moment, when mechanical arm 4 returns to the material receiving position corresponding with throwing material conveyer belt 3 again, feeding conveyer belt 2 moves.

The control mode of the control component in the invention has the following two embodiments: the first is that the control assembly is provided with a signal receiver which is arranged at the output end position of the throwing conveyor belt 3 of the rack 1, the mechanical arm 4 is provided with a signal generator, the signal generator corresponds to the signal receiver in the material receiving state, and in this case, when the mechanical arm 4 returns to the material receiving position corresponding to the throwing conveyor belt 3, the feeding conveyor belt 2 can carry out feeding operation, and the situation that the mechanical arm 4 cannot receive the material when the material is thrown out due to the fact that the throwing conveyor belt 3 moves at a constant speed all the time is avoided; in this embodiment, the signal receiver is an infrared receiver, and the signal generator is an infrared transmitter. The second is that the control component is a timing controller for controlling the feeding driving mechanism, in this embodiment, the time taken by the mechanical arm 4 to return to the receiving position after moving from the receiving position to the stacking position to release the material needs to be set as a constant time, and in the specific design, the speed of stacking also depends on the time of one working cycle of the mechanical arm 4, and the feeding conveyor belt 2 is correspondingly controlled to be adapted to the speed; it should be noted that in this embodiment, the movement of the feeding conveyor belt 2 is started earlier than the movement of the mechanical arm 4 to the receiving position, so as to compensate for the error caused by the conveying time.

In one embodiment of the invention, the conveying directions of the feeding conveying belt 2 and the throwing conveying belt 3 are parallel to each other and are positioned on the same straight line, and the conveying surfaces of the feeding conveying belt 2 and the throwing conveying belt 3 are coplanar, so that the conveying of materials is more convenient; in addition, during design, the output end of the throwing conveying belt 3 can be arranged in an upward inclined mode along the conveying direction, the design is an inclined angle of 0-15 degrees, the angle of the materials when the materials are thrown on the throwing conveying belt 3 can be changed through the design mode, different falling points of the materials are controlled, and the rear mechanical arm 4 can be conveniently adapted to the position.

According to the invention, the two material throwing components are driven by the same material throwing driving mechanism, so that the conveying speeds of the two material throwing conveying belts 3 can be synchronously adjusted, and the adjustment is convenient; or, every the throwing material subassembly is equipped with an individual throwing material actuating mechanism respectively, and this mode of setting can be adjusted alone to the conveying speed of every throwing material conveyer belt 3, can match different throwing material speeds according to actual conditions like this, carries out the comparison, and then selects better throwing material speed.

In order to ensure enough throwing force, the throwing conveying belt 3 moves at a constant speed in the working process, and the conveying speed of the throwing conveying belt 3 is 2-5 m/s; the speed comprehensively needs to comprehensively consider the weight of the materials and the conveying power of the conveying belt for experimental selection. For example, the throwing and conveying of the common cement bag can be selected to be 3 m/s.

In order to better adapt to the bag stacking operation of vehicles with different widths, as shown in the attached drawing, a distance adjusting assembly is arranged between the two material throwing assemblies, the distance adjusting assembly comprises guide shafts 5, adjusting screws 6 and a rotating handle, the two guide shafts 5 are fixed on the frame 1 in parallel, the adjusting screws 6 are fixed between the two guide shafts 5, each material throwing assembly is arranged into a whole through a base plate, the base plates are connected to the guide shafts 5 in a sliding mode, each base plate is connected with the adjusting screw 6 through a nut, the thread turning directions of the nuts connected with the adjusting screws 6 on the two base plates are opposite, and the rotating handle is arranged at one end of the adjusting screw 6; when needs adjust, drive adjusting screw 6 through turning handle and rotate, adjusting screw 6 accessible drives two in step with the cooperation of nut and throws material subassembly and move in opposite directions or back-to-back mutually, and then realizes the regulation of interval.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
