Abstract

PROBLEM TO BE SOLVED: To pack a flexible product like a pickled radish in the center of a pacing bag by keeping it straight without bending. SOLUTION: A receiving plate 21 mounted to a machine body 20 counters a pair of movable clips 23 supported by a hydraulic cylinder 22 and a pair of pushing parts 24, while being isolated by a moving path of a packing bag 12 supported by a pair of clamps 11. The movable clips 23 are respectively supported by both sleeves 27 located on a base plate 26 which is mounted to a piston rod 25. Tension of springs 28 adds forces to move the clips 23 forward. When the piston rod 25 pushes the base plate 26, the movable clips 23 push the edges of the packing bag 12 to the receiving plate 21, and resilience of the springs fixes both edges of the packing bag 12. The pair of the pushing parts 24 are constituted of rollers which can freely rotate on their vertical axes, and squeeze the packing bag on both sides of a rod-type package 16. Because the rollers 24 rotate to avoid friction with the packing bag, the rollers squeeze the package 16 to the center of the packing bag, and finally openings of the packing bag are sealed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of intermittently transporting a large number of sets of two clampers, one set at a time, along an endless track. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for shaping the posture of a rod-shaped packaged object in a wrapping bag and finishing it as a package in a bag-filling and packaging machine for putting a rod-shaped packaged object into a supporting wrapper.

[0002]

When a bar-shaped object having a low waist such as, for example, Sawaan is put into and stored in a wrapping bag suspended from a clamper of the wrapping machine, the wrapped object weighs within its own weight. It is bent in the shape of a letter and hermetically sealed, making it less productive. Although it is possible to prevent the deformation of the packaged object with a thin wrapper, it is common sense that the use of such a thin wrapper has a disadvantage that the product is poor and has a low commercial value. Conventionally, as shown in FIG. 8, a gap 4 is formed between the wide wrapping bag 1 and the gap 4 so as to allow the article 3 to pass through by temporarily squeezing the both sides of the bag 1 as shown in FIG. Disclosed is an apparatus for charging a package 3 by gravity, evacuating and sealing the inside of the wrapper, and then removing the temporary clamping pressure 2. Although the package 3 can be wrapped in the center of the wrapper 1 by such means, if the gap is narrow, misfeeding of the package is likely to occur and the packaging efficiency will not increase. There is a problem that the inclination rate of the package increases.

[0003]

In order to solve the above-mentioned problems, the present invention intermittently transfers a plurality of sets of two clampers, one set at a time, along an endless track, and stops each set at an intermediate stop section. A bag-filling and packaging machine for charging a bar-shaped item to be packaged in a packaging bag supported by a clamper in a hanging manner, wherein in the stop section behind the halfway loading section, both side edges of the packaging bag are respectively subjected to spring pressure. A pair of movable clips for holding and holding, and a double-sided pressing body which pushes the packaged object from both sides of the bar-shaped packaged product toward the center of the file wrapper, and means for deaeration of the inside of the file wrapper at the rear thereof. It consists of.

A pair of movable clips in the rear section of the section into which the package is loaded into the wrapper hold both sides of the wrapper with spring pressure to fix the wrapper. On the other hand, the double-sided pressing body pushes the packaged object toward the center of the wrapper from both sides of the bar-shaped packaged object by the pressing force. When the pressing body is formed by a roller supported on the vertical axis, the free rotation of the roller increases the effect of pushing the packaged object, and in this case, when the packaged object is vibrated, the movement of the packaged object is more. Be effective. The means for evacuating the inside of the wrapper at the back flattens the wrapper to prevent the movement of the article to be packaged within the wrapper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 4, an embodiment of a bag-filling and packaging machine supplies one of wrappers 12 stacked on a clamper 11 which is a set of two provided on the periphery of a rotor 10 as shown by an arrow 13. Then, due to the intermittent rotation of the rotor 10 in the clockwise direction, the clamper 11 suspends the wrapper 12 and intermittently moves one pitch at a time, and puts the bar-shaped packaged object into the wrapper opened at the one stop section 14. Receive filling. The following stop section 15 is provided with the following shaping means.

That is, a receiving plate 21 fixed to a machine base 20 and a pair of movable clips supported by a fluid cylinder 22 with a transfer path of a wrapper 12 supported by the clamper 11 at a stop section shown in FIGS. 23 and a pair of pressing bodies 24 face each other. The two movable clips 23 are respectively supported by sleeves 27 on both sides of the substrate 26 fixed to the piston rod 25, and the tension of the spring 28 urges the two movable clips 23 to push them forward. Therefore, when the piston rod 25 pushes out the substrate 26, the movable clip 23 pushes the side edge of the wrapper 12 against the receiving plate 21 and the spring 28
The reaction force locks both sides of the wrapper 12 (see FIG. 3). On the other hand, the pair of pressing members 24 on both sides are formed by rollers rotatably supported on the substrate 26 via the longitudinal axis.
Numeral 4 narrows the wrapper 12 on both sides of the bar-shaped package 16. As a result of the rollers 24 rotating to avoid friction with the wrapper, the article 16 to be packaged is pushed into the center of the wrapper.

In FIG. 1, a screw rod 50 provided on the substrate 26 is provided.
With the rotation, the distance between the rollers 24 on both sides can be adjusted according to the thickness of the article 16 to be packaged.

In FIG. 1, a cylinder 25 and a fluid pump 3
A vibration device is formed such that the electromagnetic switching valve 31 installed on the line connecting the zeros is switched in small steps by the oscillating radio waves of the switching power supply 32. By the operation of such a device, the roller 24 applies vibration to the packaged object 16 and urges the auxiliary movement of the packaged object. In addition, the vibration device 35 which pushes up the packaged object 16 from below as shown in FIG. 3 is more effective.

In the rear section 15 in FIG. 4, after the articles to be packaged are pushed into the center of the wrapper, the two clampers 1
1 is separated as shown by the arrow. This is in a state as shown in FIG. 5, and the separation of the two clampers 11 causes the vicinity of the bag mouth of the wrapper 12 to be tense, so that the upright posture of the packaged object 16 is maintained. In this case, by holding the posture of the packaged object 16 more effective by reducing the amount of air inside the envelope 12 by blowing the pressurized air 36. This is one mode of "degassing" described in the claims.

In FIG. 4, the wrapper moves further to the final section 37, where it is squeezed with sponge rubber from both sides to eliminate the internal air and to evacuate, while at the same time heat sealing the lip of the wrapper 12. When degassing and sealing are not performed in the section 37, the wrapper 11 is transferred to the vacuum chamber while holding the bag opening from the section 37, and degassing and sealing with different Pascal values are performed in the vacuum chamber. Note that these also correspond to “degassing” in different modes.

FIG. 6 shows an embodiment in which a central receiving plate 21 is used.
FIG. 7 shows an embodiment in which opposing pressing means have the same structure.
