Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for opening nine bags containing powdered barium, cement, feed, fertilizer, etc.

[Conventional technology]

Conventionally, powdered barium, cement, feed 1,2! Several methods have been proposed for opening a paper or nylon bag containing powder or granular material such as food. For example, Japanese Patent Application Laid-open No. 59-134157 K discloses a method in which the bag is placed in a horizontal position and the entire center section thereof is cut with a saw.
No. 84931 discloses a method of cutting with a disc rotating cutter, and No. 59-221231 discloses a method and device for cutting with a cutter fixed to the tip of a cylinder rod.
In both cases, the opening is directed downward, allowing the contents to fall and be removed by gravity.

[The problem that the invention attempts to solve]

However, when cutting with a saw, there is a problem in that the contents are mixed with chips from the bag that are generated during cutting. Also saw 1
Since a disc rotary cutter cuts by vertical and rotational motion, there is a risk that the content may be altered by the frictional heat generated during cutting.

If the cutter fixed to the tip of the cylinder rod is used to press the cylinder rod, the above problem does not occur, but the power needed to press the cylinder rod is equivalent to that of a small press, making the device larger. In addition, both devices have a device that directs the opening of the bag downward, and when the opening of the bag is directed downward,
Since the holding device for holding the bag and the empty bag are divided into two parts, there is a problem that the take-out device for depositing them is large-scale.

Therefore, in order to solve the disadvantages of the conventional methods, the present invention provides a method for opening a stuffed bag, in which the empty bag is opened with a cutter that moves directly on the side of the bag so that the empty bag does not separate into two and chips are not generated. and its equipment. Another object of the incision method of the present invention is to minimize the deterioration of the contents due to heat generated when opening the bag.

[Means for solving problems]

The structure of the present invention for achieving the above object will be explained with reference to FIGS. 1 to 4 corresponding to the embodiments. In FIG. It is attached to the plate (4) passed to the chain (6), and the sprocket is rotated by an electric motor (5). Further, a roller (6) is installed between the two chenos (3) to prevent the bag from easily falling through the contents outlet (12).

The bag (P) inserted from the bag insertion port (13) is moved by the roller (
6) can be received within the device. To secure the bag, use a needle (
7) is inserted into the υ bag by the cylinder (8).
5) Kyo Shikatatsuta (1) cuts open the entire lengthwise side of the bag. The bag is fixed in the device by a needle (force), so only the contents fall downwards due to gravity.If the contents do not come out completely from the bag with the above operation, use the needle to completely remove the contents. (7) may be made hollow, and the air may be released through a hole made around the tip and needle (force) to inflate the bag and removed.Furthermore, the contents may be shaken out using a vibration device (not shown). .The roller (6) is the content outlet (12)
When it reaches the bottom, turn off the motor and remove the stopper needle (7) from the bag.

An empty bag ejection plate (10) fixed to the tip of a rod of an empty bag removal cylinder (9) is moved toward an empty bag discharge port (11) by the operation of the cylinder, and the empty bags are discharged from the apparatus.

〔Effect of the invention〕

According to the present invention, since the longitudinal side surface of the bag is cut with a cutter that moves linearly, the bag is not divided into two, making it easy to dispose of the empty bag, and no chips are generated. Furthermore, since there is almost no heat generated during incision, deterioration of the contents can be minimized.

Since the structure is simple and the operation is simple, the entire device can be made small and lightweight.

[Brief explanation of the drawing]

Fig. 1 is a sectional view taken along the line A-A of the bag opening device according to the present invention, Fig. 2 is a front view of Fig. 1, Fig. 5 is a side view, Fig. 4 is a plan view of a portion of the cutter, and ω) is a C) is a front view, C) is a side view, and FIGS. 5 and 6 are conventional techniques.

Claims (2)

[Claims] (1) A method for opening a stuffed bag, which is characterized by turning the longitudinal side of the bag containing the contents downward, cutting the entire side with a cutter, and letting the contents fall by gravity. (2) a plurality of needles and their driving device for fixing the bag containing the contents; and an incision device for cutting the entire side of the bag;
A bag opening device for stuffed bags, comprising an empty bag ejecting device for ejecting empty bags to the outside of the device.
