Description

Fiber bag removing belt for straight-moving bale plucker, bale opener and method

Technical Field

The invention relates to a fiber bag removing belt and bag opening machine and method for a straight-moving bale plucker, and belongs to the technical field of textile equipment.

Background

A straight-line reciprocating automatic bale plucker (hereinafter referred to as "straight-line bale plucker") is a first processing device in a spinning process, and is used for grabbing fiber blocks from a fiber bale and conveying the fiber blocks to a front machine station for further processing. Before processing, the fiber bag is wrapped with a packaging bag, and is bound by a plurality of packing belts which are vertical to the length direction of the fiber bag. Before grabbing the package, the processes such as conveying and removing the belt of the fiber package are completed manually, the labor intensity is high, the time is long, and under the background of the rise of the current labor cost and the shortage of labor in textile factories, the processes such as conveying and removing the belt of the fiber package need to be realized by adopting an automatic mechanical device urgently.

The Chinese patent application, which is filed on 2019, 12 and 11, and has the application number of 201911264359.9, and the name of automatic bale arranging machine and automatic bale arranging method for a straight-line bale plucker, discloses an automatic bale arranging machine and method for a straight-line reciprocating type automatic bale plucker. The discharging machine hooks the packing belts by using the belt hooks of the belt hooking device before cutting the packing belts, and releases the state of the hooked belts through the reverse rotation of the belt hooks after finishing cutting the belts so that each packing belt falls under the action of gravity for collection. However, the packing belt bundles the fiber bags tightly and is trapped in the fiber bags, the packing belt hook is not easy to be taken by the belt hook, and the packing belt is not stably controlled by the belt hook after the cutting of the belt is finished, so that the packing belt is easy to be scattered in the process of dropping the packing belt, and the centralized collection of the packing belt is not facilitated. In addition, the strapping machine adopts the strapping tool to cut the strapping belt, the common strapping belt is difficult to break and easy to cut, the force applied to the strapping belt in a single-blade cutting mode is mostly the pulling force, the cutting effect is not ideal, and the requirements on the strength of the tool and the tool support are high. Furthermore, the waste strapping bands removed from the fibre bales fall directly into a collection bin for collection, which causes the following problems: firstly, the volume of the waste belt collecting box is limited, the packing belt is loose when falling, and the collecting box needs to be frequently replaced, so that the efficiency is low and the waste is serious; secondly, when the collecting box is manually replaced, the collecting box is heavier and slower in replacement speed due to the fact that the machine is still in operation, so that danger is easily caused to operators, and the efficiency is relatively lower if the machine is stopped and replaced; third, if the full collection box is not replaced in time, the strapping band will overflow from the box and prevent the entire bale conveyor and the debagging device from operating, or even be dangerous. In addition, the discharging machine only cuts the bottom of the packaging bag during the bag opening work, the removal work of the packaging bag is difficult to realize in practical operation, and the packaging bag can only be removed in a mode of lifting the packaging bag upwards by the device, so that a large longitudinal working space is required. In addition, the transportation platform for the fiber bales of the discharging machine is provided with a movement path by a fixed track, the track occupies a large area, and is difficult to install and high in cost.

Therefore, the technical field needs to solve the problem of how to improve the working efficiency, stability, reliability and operation safety of the automatic equipment when the automatic equipment is adopted.

(6) As shown in fig. 22, the hook strip cassette carrier 205 drives the hook strip device 2 in the direction of the solid arrow shown to the farthest distance from the bale of fibers 10'; the hook belt mechanism carrying mechanism 203 drives the hook belt mechanism 202 to move to the highest position of the stroke according to the direction of the solid arrow; the tape-cutting box carrying mechanism 305 drives the tape-cutting device 3 to move to the position farthest away from the fiber package 10' in the direction of the solid arrow; the tape-cutting mechanism carrier 303 drives the tape-cutting mechanism 302 to move to the highest position of the stroke in the direction of the solid arrow, and the tape hooking device 2 and the tape-cutting device 3 complete the reset action.

(7) As shown in fig. 23a and 23b, the bale support plate 105 of the bale conveyor 1 cooperates with the conveyor belt 5031 and the rollers 5032 of the bag slitting device 5 to convey the bale 11' with the removed bale tie 10a to the bag slitting station 114 in the direction of the solid arrow shown.

(8) As shown in fig. 24, the bottom cutting mechanism 501 cuts the outer portion of the fiber package from which the wrapping tape has been removed along the bottom diagonal line, and then lifts the fiber package 11' up to a certain height.

(9) As shown in fig. 25a and 25b, the air cylinder 603 drives the bag clamping device 6 to move to the bag clamping station 115, and then the first pneumatic clamping jaw 606 and the second pneumatic clamping jaw 606 'are closed to clamp two corners of the packaging bag 10b of the fiber bag 11'; the bag suction rodless cylinder 702 drives the bag suction device 7 to move to the bag suction station 116, and then the pneumatic suction cups 704 suck the side faces of the packaging bags 10b of the fiber bags 11'.

(10) As shown in fig. 26, the first linear module 5021 drives the first knife 5022 to cut one side line of the left side of the packing bag 10b in the vertical direction of the arrow, the second linear module 5021 'drives the second knife 5022' to cut the other side line of the left side of the packing bag 10b in the vertical direction, and the rodless cylinder 5023 drives the third knife 5022 ″ to cut the upper side line of the left side of the packing bag 10b in the arrow direction.

(11) As shown in fig. 27a and 27b, the air cylinder 603 drives the bag clamping device 6 and the waste packaging bag 11b 'to move to the first waste bag collecting station 117, and the waste packaging bag 11 b' is discarded to the first waste bag collecting device 8; the first waste-bag collecting device 8 then conveys the waste packing bag 11 b' into the waste-bag collecting box 806; meanwhile, the bag suction rodless cylinder 702 drives the bag suction device 7 and the waste packaging bag 11b 'to move to the second waste bag collecting station 118, the waste packaging bag 11 b' is discarded to the second waste bag collecting device 8 ', and the second waste bag collecting device 8' conveys the waste packaging bag 11b 'to the waste bag collecting box 806'; then the first cutter 5022, the second cutter 5022 ', the third cutter 5022' and the top package frame 5012 complete the reset action; the bale 11 'with the strapping band removed is converted into a bale 12' with both strapping band and packaging bag removed.

(12) As shown in fig. 28, the conveyor 5031 and the rollers 5032 of the bag slitting device 5 convey the fiber pack 12' in the direction of the illustrated arrow to the station 119 to be carried.
