Description

Wrapping bag supplies bag to get a bag and props a bag equipment

Technical Field

The utility model relates to a supply the bag to get the bag and prop a bag equipment, in particular to wrapping bag supplies the bag to get the bag and props a bag equipment belongs to the equipment for packing field.

Background

Along with the continuous development of the innovation and development of China, the living standard of people is improved day by day, people also get unprecedented cognition on the physical health problem, in addition, because the education level of China is improved, the cultural degree of China is improved, the people engaged in mental labor are increased continuously, in recent years, along with the sufficient development of industrial modernization, the cost of human resources is increased gradually, particularly, the problems of large personnel mobility, unstable personnel and difficult recruitment exist in certain working posts with large dust and heavy physical strength, and only the personnel can be kept with high salary. In market competition, the long-term operation of production can be ensured at low cost, the profitability is the basic guarantee of long-term existence and continuous development of factories, and the improvement of the automation degree of production equipment is particularly important for reducing the increasing human resource cost.

In the packing trade, many products use bag form packing, traditional product bagging-off process mainly utilizes artifical handheld wrapping bag, cover to unloading funnel department, treat that the material seals after filling up, repeated work makes workman intensity of labour big like this, produce fatigue easily, easily cause the bagging-off position depth of cover to differ, the material is filled not in place, the low scheduling problem of production efficiency, and in the great post of some dusts, can bring certain influence to staff's health, in view of these many aspects of reason, automatically, provide the wrapping bag, automatic bagging-off has become the consensus in the industry.

The braided bag is one kind with low costs, convenient to use's wrapping bag, can not only be used for in the great granule material, also can be used to cement, in various powders such as flour, because its application range is extensive, the transport of wrapping bag, supply apparatus is also diversified, the general confession bagging apparatus of getting the bagging apparatus is a belt conveyer, the wrapping bag is directly put on belt conveyer, two piles of wrapping bags are placed to primary level, after one pile of wrapping bag was got, the conveyer belt rotates, fold the second and send into, after the second is folded and has been got, put into new wrapping bag by the manual work again, this kind of confession bag mode has following several shortcomings:

1) because the number of each stack of packaging bags is limited, the packaging bags can be taken out quickly, and an operator needs to put the packaging bags into the packaging bags again immediately, so that the operator cannot leave the packaging bags for a long time;

2) to increase the bag supply, the conveyor belt is extended, which increases the area occupied by the apparatus.

The prior bag taking method comprises the steps that the bags are transversely sucked and conveyed along the long edge direction of the packaging bags by the bag taking device, bag suction nozzles suck the bags from the upper layers of the stacked packaging bags along the edges of a packaging bag field, the packaging bags are lifted to a certain height above an operation platform after being sucked, then the packaging bags are transversely moved to the middle position on the platform, then the suction nozzles are closed, the packaging bags naturally fall onto the platform by the aid of the self weights of the packaging bags, and finally the bag openings are opened by the suction nozzles; the mode of carrying, sucking and propping the mouth of the packaging bag has the following defects:

A. the bag-taking suction pipe is longer, and the suction nozzle has more openings, so that the suction nozzle is required to provide higher negative pressure to ensure enough suction force, and the defect of higher energy consumption exists;

B. because the bag taking suction pipe is longer, the suction nozzle has more openings, and the bags are sucked along the edge of the packaging bag, if the packaging bags are stacked untidy or the packaging bags have folded corners, the suction nozzle can be connected with the lower layer of packaging bags, so that the fault of the suction error of the packaging bags occurs;

C. after the suction nozzle sucks the packaging bag, the suction nozzle moves upwards firstly and then moves horizontally to the operating platform, the running distance is long, and the bag falling fault is easy to occur if the packaging bag is not sucked;

D. when the bag is taken, if the absorbed packaging bag is adhered to the packaging bag below, the packaging bag below can be displaced when the packaging bag above is taken, so that the absorption fault can occur when the bag is taken next time;

E. when the mouth of the packaging bag is provided with a break angle, the bag opening suction nozzle is easy to break down when the mouth of the packaging bag is opened; moreover, even if the bag mouth is bent, an operator can hardly find the bending phenomenon in the stacking process;

F. after the packaging bag moves onto the platform, because the packaging bag naturally falls onto the operating platform, the bag opening of the packaging bag is not parallel to the edge of the platform easily, and the bag opening suction nozzle is designed to be parallel to the edge of the platform, so that when the bag opening of the packaging bag is sucked and opened by the suction nozzle, faults easily occur;

in summary, the existing packaging bags have uneven quality and insufficient flatness, cannot meet the requirements of the existing conveying and supplying device, the existing bag taking and opening device, have high requirements on the packaging bags, and otherwise have faults in the aspects of bag suction and bag opening.

How to overcome the defects, how to shorten the length of the conveying belt, save the occupied space of equipment, ensure that the packaging bags are accurately supplied to the bag taking positions of the bag taking equipment in quantity and positioning, and reduce the frequency of continuously placing the packaging bags on the conveying belt is a new requirement of the packaging field for the packaging equipment and is also a major subject existing in the packaging industry at present.
