Description
Technical field
the invention belongs to fully-automatic packaging machinery technical field, be specifically related to a kind of oscillating-type and embrace a bag conveying mechanical arm structure, be matched in Openmouthed bag fully-automatic packaging piling flow production line.
Background technology
as is known in the industry, the radical function of Openmouthed bag fully-automatic packaging piling flow production line is automatically to pack and automatic stacking, automatically packing is radical function, automatically packaging function is mainly realized by following equipment: automatic metering scale, automated bag storehouse, automatic bag feeding machinery hand, automatic clamp bag mechanism, automatically clap turn-up mechanism, automatically fortune bag dolly, seal automatic introducing mechanism and automatic sealing, the course of action of these equipment is followed successively by: automatic metering scale is weighed to material dosing, automated bag storehouse provides an empty Openmouthed bag, upper bag manipulator extracts an empty bag and sky bag is overlapped to automatic clamp bag mechanism, automatic clamp bag mechanism is lived sackholder, batch scale is discharged into the material weighing up in empty bag, automatically clap turn-up mechanism and clap bag, automatically fortune bag dolly is embraced bag to embrace bag, automatic clamp bag mechanism opens by pine, fortune bag dolly is delivered to sealing automatic introducing mechanism place from automatic clamp bag mechanism by contracted affreightment and is sealed by automatic sealing.
in said process, fortune bag dolly (fortune packing is put) takes off the full bag of filling material that to be transported to automatic sealing introducing mechanism be an important step from automatic clamp bag mechanism, because the speed of this link not only affects the speed of whole automatic packaging process, and in fortune packet procedures, the quality of the shape of bag also can affect the effect of sealing.The vibration producing in this outward transport packet procedures and the wearing and tearing of consumable accessory also can affect the reliability of automatic packing.
fortune packing in prior art is put and is mainly contained two kinds: the one, and the little vehicle of horizontal motion fortune bag.Fortune bag dolly moves on horizontal guide rail, is made to wrap in to clap on wrapper sheet and conveyer to drag to the automatic introducing mechanism direction level of sealing by fortune bag dolly under the state of embracing full bag.One of shortcoming of existence, fortune bag moving of car speed is slow, and because in the motion process of bag, cliding friction motion is done at bat wrapper sheet and conveyor belt surface in the bag end, and therefore, resistance is large, and the required propulsive effort that moves is also just large, and kinematic velocity is slow; Two, the upper bag speed of bag manipulator in impact, because bag manipulator could be set to next empty bag on automatic clamp bag mechanism on after must the position below fortune bag dolly goes out contracted affreightment bag-clamping mechanism; Three, range of use is restricted because as bag in institute the material ratio that fills softer, in the process that drags bag, wrap shape mutability, thus impact seal effect, therefore range of use is restricted; Four, power consumption is large.The 2nd, horizontal motion fortune bag dolly adds bag-clamping mechanism lifting type.It adds a set of bag-clamping mechanism that can vertical lift by the fortune bag dolly of a horizontal motion again and forms.Move horizontally and transported bag by fortune bag dolly; Bag-clamping mechanism by lifting mode is made vertical displacement movement, abdicates in time bag space, so that upper bag manipulator shifts to an earlier date overhead bag, to improve upper bag speed.The concrete grammar of fortune bag is: the fortune bag dolly moving on horizontal guide rail is embraced full bag, drags to package introducing mechanism direction wrapping on bat wrapper sheet below and conveyer.In fortune bag dolly horizontal motion, liftable bag-clamping mechanism vertical uplift, bag is not also transported out the position below bag-clamping mechanism by level like this, and because bag-clamping mechanism has risen to a high position, upper bag manipulator can be to the next empty bag of bag-clamping mechanism cover.Therefore the fortune bag method of this device and the fortune bag method of the first device are compared, and major advantage is to have improved the speed of upper bag manipulator overhead bag, namely goes up bag manipulator and can shift to an earlier date overhead bag.But the kinematic velocity that transports the fortune bag dolly of bag does not improve, fortune bag delivering trolley and upper a kind of to transport the fortune bag dolly that packing puts middle use be identical.Because bag-clamping mechanism is heavier, bag-clamping mechanism is again the passage of material stream passed, and its lifting has also brought some other problem.This fortune is packed one of major defect of putting, and fortune bag moving of car speed is slow, because in the motion process of bag, is clapping wrapper sheet and carrying on zone face and do cliding friction motion at the bag end, and therefore, resistance is large, and the required propulsive effort that moves is also just large, and kinematic velocity is slow; Two, structure heaviness and cost are high because increased the lifting of bag-clamping mechanism, therefore cost is put and is significantly improved than the first fortune packing; Three, owing to having increased the lifting of bag-clamping mechanism, therefore consumable accessory is more; Four, range of use is restricted, for example, when institute's material ratio that fill in bag when softer, wraps shape mutability in the process that drags bag, thereby affects the effect of sealing.
self-evident, if there is more reasonably fortune packing to put the existing device that replaces aforementioned two types of replacement, being not limited to so shortcoming recited above can eliminate.The applicant has carried out patent and non-patent literature retrieval, but there are no any referential technology enlightenment, for this reason, the applicant has done positive and useful design, and technical scheme described below produces under this background.
Summary of the invention
task of the present invention be to provide a kind of help avoid be filled with wrapping in of material in motion process, there is the cliding friction between load-transfer device and use reduce the resistance of motion of bag and reduce propulsive effort that fortune packing puts reducing power consumption, be conducive to improve the transfer velocity to bag and use and improve filling efficiency, be of value to and prevent that bag from deforming and use and ensure sealing effect, have and be convenient to simplified structure and use the oscillating-type that embodies economy and embrace a bag conveying mechanical arm structure.
