Problems solved by technology

For the granular material package, Italy has developed an automatic feeding and cutting system for the polymer particle material package, which uses a manipulator to move the material package to a special cutter head bag breaker, then puts the material bag down, and the material bag falls to the cutter head This system is easy to break the woven bag and cause the problem that the woven bag debris pollutes the raw material
Similarly, some domestic automatic unpacking devices also have this problem, such as Chinese patent CN2013102767140 and patent CN201510116184, both use saw blades or blades to destructively unpack bags, which is prone to bag debris
[0004] Chinese patent CN2015108873053 has improved this problem. When the bag is broken, the bag debris will not fall into the material pool with the material, but it still has the incomplete whereabouts of the material in the material bag, and it is easy to fall into the folds and corners of the material bag. The problem of residual material
However, Chinese patent 2016110411377 uses a magnetic needle as an unloading tool, and the needle moves up and down to make the bag vibrate to help discharge the residual material. Chinese patent 2017100372455 helps discharge the material by vibrating and beating the bag from the outside. These devices or methods were found in the test. The jitter produced in the process is better for square brick-shaped material packages, but its strength and effect are not good enough for ordinary non-stereo-formed material packages. Due to many folds, it is still easy to leave residues in some corners, especially in the stacked places. Therefore a new device for unpacking and unloading is required
[0005] It can be seen that the automatic unpacking and unloading device in the prior art often produces packaging bag debris, which is easily mixed into the material, and the incomplete whereabouts of the material causes the problem of waste of residual material

Embodiment 2

[0096] Different from Example 1, in this example, if Figure 9 As shown, the hanging pin 14 is embedded into the first end effector 18 in a locking structure.

[0097] Hanging needle 14 adopts steel needle, and its needle head 141 is the needle point 1411 of conical sharpening, is provided with a pair of groove 1413 opposite to the top of needle body 142, groove shape can adopt spherical, columnar or cuboid shape.

[0098] The first end effector 18 is still provided with an inverted tapered accommodating chamber which is suitable for the needle head 141 and is slightly larger than the needle head. At the end of one side of the accommodating chamber, a pair of grooves 1413 for holding the needle are arranged. bit snap-in modules. The clamping module includes a clamping ball 181 and a spring 184 connected in sequence, the latter is fixed on the spring seat 183 and drives the clamping ball 181 to move left and right through the sliding tube 182 . Preferably, a frusto-conical po...

Embodiment 3

[0104] Different from Example 1, in this example, if Figure 5E As shown, on the first section of the wave track, that is, the sharp track, for the smooth track, in the segment with a smaller curvature, by adding a plurality of convex and concave segments with a smaller radius of curvature, the tow bag manipulator can move in the following During the forward process of the speed strategy, the centripetal force and centrifugal force required to generate steering acceleration in the small segment are increased, thereby increasing the multi-directional force of the residual material particles.

Abstract

The invention discloses a fluctuating bag shaking-type automatic discharging device. The fluctuating bag shaking-type automatic discharging device comprises a conveyor belt, a bag cutting table, a cutting mechanism and a bag shaking mechanism, wherein the conveyor belt is used for conveying a material bag and transferring the material bag from a horizontal state to a tilted state; the bag cutting table is connected to the tail end of the conveyor belt and is used for conveying the material bag to and stopping the material bag at the cutting position and providing gaps for hanging needles to penetrate through and hang the material bag; the cutting mechanism is mounted on the bag cutting table and unpacks the material bag when the material bag is carried to a preset position; the bag shaking mechanism is provided with a wave track and a bag dragging manipulator, and the bag dragging manipulator is used for bearing the hanging needles on which the material bag is hung, driving the hung material bag to move forwards on the wave track in a variable-speed zigzag fluctuating manner and shaking the material bag. According to the fluctuating bag shaking-type automatic discharging device, automatic unpacking and discharging are achieved; a wave speed change method is adopted for shaking the bag by referring to expert experience, residue-free blanking is achieved, and raw material waste is prevented; and the reusable hanging needles are adopted as traction tools, so that the tool consumption is reduced.

Description

technical field [0001] The invention relates to the field of automatic feeding in industrial production, in particular to a wave-shaking bag-type automatic unloading device. Background technique [0002] The main raw material for the production of plastics such as biaxially oriented film BOPP is polymer particle PP material, which is packed and transported in woven bags. At present, most of the feeding of granular materials in China is done manually, and there are many disadvantages in manual feeding. First of all, manual feeding seriously reduces the degree of automation of the process, and manual unpacking is labor-intensive and prone to fatigue, resulting in unstable feeding speed, and it is prone to the problem that the manual speed cannot keep up with the supporting continuous production equipment; secondly, the feeding and cutting of material packages is a It is a heavy and tedious manual labor, and it is difficult for humans to efficiently and smoothly feed materials...
