Abstract

The utility model relates to an automatic checking weight weigher, which is characterized in that both ends of a weighing platform of a weighing module are fixed with connecting plates; a belt pallet is fixed on one side plate; a driving wheel and a driven wheel which are sheathed with conveyer belts are installed at both ends of the side plate; the side plate which is fixed with a belt adjusting device is fixed on the connecting plate; a motor and a weighing sensor are fixed on the weighing platform. The product can automatically weigh and detect to each on-line product, and can automatically eliminate overweight or underweight products.

Description

Automatic check weiger

The utility model relates to a kind of discrete load or single load of diffusing shape article to quantitative package and carries out that weight is veritified, the automatic balance of classification, particularly a kind of Automatic check weiger.It can not only be widely used in the weight test and the quality control of automatic packaging production line, and the overweight or short weight product on the automatic packaging production line can also be rejected automatically.

The mode inspected by random samples is taked in domestic control to product weight at present mostly, can not guarantee that each product that dispatches from the factory all obtains check, can not guarantee that each product that dispatches from the factory all is certified products.Domestic is being blank aspect such Automatic check weiger of manufacturing, so annual country all will spend a large amount of foreign exchanges to buy this series products.

The purpose of this utility model is a kind of Automatic check weiger of development, it be collection micro computer, automatically control, photoelectric control, machine-building etc. multidisciplinary with one and have that precision height, speed are fast, reliable operation, simple, the cheap characteristics of installation and maintenance.It can be rejected the product of overweight or short weight automatically to each in the line products detection of weighing automatically, thereby has ensured the qualification rate of product.

The utility model is achieved in that Automatic check weiger comprises electric appliance box 1, transition module 2, photoelectric testing sensor 3, Weighing module 4, the solid-state relay SS R1 of LOAD CELLS 10 and 5 controls of micro computer central controller, SS R2 and overweight sorting topworks 8, short weight sorting topworks 9, it is characterized in that: Weighing module 4 is by LOAD CELLS 10, weighing platform 11, web joint 12, side plate 13, belt tray 14, belt conveyor 15, motor 16, driving wheel 17, belt adjusting gear 18 and follower 19 are formed, LOAD CELLS 10 by screw retention on weighing platform 11, be fixed with web joint 12 at the two ends of weighing platform 11, belt tray 14 is fixed on the side plate 13, driving wheel 17, follower 19 is contained in the two ends of side plate 13, belt conveyor 15 is sleeved on driving wheel 17 and the follower 19, side plate 13 by screw retention on web joint 12, belt adjusting gear 18 is fixed on the side plate 13, and motor 16 is fixed on the weighing platform 11.

The wheel surface of driving wheel 17 and follower 19 is shaped as swelling-waist shape, and it can realize that belt corrects the purpose of sideslip automatically.

LOAD CELLS 10 is to adopt resistance strain weighing transducer

Good effect of the present utility model is:

1. this product adopts unique weighing structure and advanced microcomputerized control display technique, and each in the line products detection of weighing automatically, is rejected overweight or short weight product automatically, has ensured the qualification rate of product.

2. the LOAD CELLS of this product is to adopt resistance strain weighing transducer, and the reaction velocity of weighing is fast, the data stabilization time is short, has improved accuracy and work efficiency that the user measures operation.

This product have automatically, manually zero setting, sum and qualification rate statistics, store, quiet dynamic weighing, outage is protection automatically, rejects unacceptable product automatically, functions such as weight feedback.

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 1,2,3,4,5, shown in, the formation of Weighing module 4 is: LOAD CELLS 10 by screw retention on weighing platform 11, be fixed with web joint 12 at the two ends of weighing platform 11, belt tray 14 is fixed on the side plate 13, driving wheel 17, follower 19 are contained in the two ends of side plate 13, and belt conveyor 15 is sleeved on driving wheel 17 and the follower 19, side plate 13 by screw retention on web joint 12, belt adjusting gear 18 is fixed on the side plate 13, and motor 16 is fixed on the weighing platform 11.As Fig. 1,6, shown in 7, object to be detected 20 by transition module 2 through Photoelectric Detection, send signal by photoelectric testing sensor 3 to micro computer central controller 5, register in the micro computer central controller 5 and timer begin numeration and timing, when object to be detected 20 arrives the certain position of Weighing module 4, data acquisition module BOB(beginning of block) in the A/D analog-to-digital conversion module 7710 is gathered the weighing-up wave of LOAD CELLS 10 outputs, through delivering in the micro computer central controller 5 after 7710 conversion of A/D analog-to-digital conversion module, its model is 89c52, micro computer central controller 5 is handled according to certain calculation, forms product weight data and enumeration data.To count then and the result of weight delivers to the DISPLAY display module and shows, counting and weight data also can mail to host computer by the TXD standard serial port in the micro computer central controller 5 and manage, these data of weighing compare with the reference value that is set in the micro computer central controller 5 in advance simultaneously, judge this and weigh data whether in the error range of regulation, data are not in the error range of regulation if this is weighed, then further judge to be overweight or short weight, if it is overweight, then send sort instruction to solid-state relay SSR1, solid-state relay SSR1 connects, and overweight sorting topworks 8 accurately rejects object to be detected 20 when object to be detected 20 runs to certain position by belt conveyor 21 automatically.If short weight then sends sort instruction to solid-state relay SSR2, SSR2 connects, and short weight sorting topworks 9 accurately rejects object to be detected 20 when object to be detected 20 runs to certain position by belt conveyor 21 automatically.When weight was accurate, micro computer central controller 5 did not send instruction to solid-state relay SSR1, SS R2, and object to be detected 20 passes through on belt conveyor 21.The operator can finish various setting operations by load module KEY.Solid-state relay SSR1, SSR2 are connected with short weight sorting topworks 9 with overweight sorting topworks 8 by cable 22.
