Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bagging inspection method for testing the bagging strength of bagged products.

Structure of conventional example and its problems In grain bagging equipment, thick polyethylene is used as the packaging body, and when bagging is completed, the upper end opening (3) that used to be the grain input port [see Figure 4] is heat sealed. Figure 3 shows the packing scale /I/ (t) as a bagging device and this packing scale /I/ (t).
I/ (1) shows the compactors (3) and (4) that send the bagged products (2) to the subsequent stage. (5) has rolled up the package to be fed to the para-king scale (1)! It is a limb. Packing Skate-A/ (1) pulls out the cylindrical packaging body from the wrapping body (5) by the required length and inserts the grain into the bag with the lower end opening (B) (see Figure 4) heat-sealed. Grain loading is started, and when the amount of grain input reaches a predetermined weight, the loading of grain is stopped, and the upper opening is heat-sealed as described above, and the packed product (2) is transferred to the conveying device (3) ( 4), all I had to do was send it to the next stage.

However, in the past, the upper end opening (a) and the lower end opening (
In some cases, the heat seal in B) may be incomplete; for example, the top opening (4) or bottom opening (B) of such products may be torn during loading and unloading at a store. The grain is spilled. Therefore, conventionally, it has been visually inspected to see if C μ is sufficient.
Currently, it is not possible to reliably exclude products with defective packaging.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a bagging inspection method that can eliminate incompletely packed products in advance.

Structure of the Invention The bagging inspection method of the present invention is characterized by measuring the weight of a bagged product before and after passing through a packing strength test section, and comparing both weight values for the same product to determine the quality of the packing. shall be.

DESCRIPTION OF EMBODIMENTS The bagging inspection method of the present invention will be described below with reference to FIGS. 1 and 2 showing specific embodiments. In addition, Figures 3 and 4
Components that are the same as those in the figures are given the same reference numerals and their explanations will be omitted.

FIG. 1 shows a first embodiment of the present invention, showing a packing scale-iv (t) as a bagging device and a conveying device in its succeeding stage.

Is the conveyance device directed from the upper side (fc) to the lower side (2)?
``JFtK conveyor (3), conveyor (6), conveyor (7), and conveyor (4) are arranged to constitute the conveyance route. Conveyors (6) and (7) each have separate weighing machines <8
) (9) and is supported via a conveyor (
7) is also arranged at a lower position than the conveyor (6), and a step (C) is formed between the conveyors (6) and (7).

Because of this planting, the bagged products (2) are transferred from the conveyor (3) to the conveyor (6), and while being conveyed by the conveyor (6), the weighing machine (8) measures the weight M. , has been measured. The product (2) that has passed through the conveyor (6) falls down the step (C) and reaches the top of the conveyor (7), and while being transported by the conveyor (7), the weight value M2 is measured by the weighing machine (9). Ru. The product (2) that has passed through the conveyor (7) is further transferred to the lower side (D) by the conveyor (4).
) will be sent to.

If the packing is perfect, both the top opening (4) and the bottom opening (Bl) will not be torn even if the product (2) is dropped on a step (c), but if the heat seal is insufficient, When the bag is dropped from the step (c), it ruptures and the grain inside spills out.In other words, the weight values M and M in the processing bag @QO
2, if M, = M2, it is determined that the heat seam μ is completely good, and if M, > M2, it is determined that it is a defective product with insufficient heat seam μ, and a pass/fail judgment signal (6) is generated. . Therefore, shipping of defective products can be prevented by simply checking this quality determination signal Qη.

FIG. 2 shows a second embodiment. In Figure 1, the packing strength test section is a step between conveyors (6) and (7).
c), but in Fig. 2, the packing strength test section consists of a vibrating conveyor Q4 consisting of a conveyor (2) and a vibrating machine that applies vibration to this conveyor (2).
The product (2) is conveyed on a conveyor while being vibrated, and the weighing values M and tM2 before and after passing through the conveyor are compared by the processing device OQ to similarly judge the quality.

In addition, in FIG. 1 and FIG. 2, the processing device aO is the bagging target weight M in the packing scale -/v(1). Compare M with weighed value M. If ±m<M (where m is a tolerance), it is assumed that there is an abnormality in the loading of the packing scale A/ (1), and a defective pass/fail determination signal Qη is generated.

In the embodiment shown in Fig. 2, the vibrating conveyor α was composed of a belt-rotating conveyor and a vibrator (2), which vibrates the trough with the vibrator (2) and Even if the product (2) is conveyed while jumping, the fire resistance of the package can be checked.

As described in the detailed description of the invention, the bagging inspection method of the present invention measures the weight of the bagged product before and after passing through the packing strength test section,
Since both weight values for the same product are compared to determine whether the packaging is good or bad, it is possible to know whether the product's packaging is good or bad, and it is possible to prevent products from being shipped that may have packaging defects, and to reduce the number of bags in the market. This can prevent accidents such as tearing. Furthermore, since it is sufficient to simply compare the weight values, the inspection device can be provided at a low cost.
