袋装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is directed to a bag-filling and packaging machine from a bag loading station where a large number of packaging bags are stacked. The present invention relates to a bag feeding device that supports and supplies bags.

響を受けにくいことがわかつている。(Prior Art) When bagging a large quantity of items to be packaged in fixed quantities in fixed cycles, the operation of feeding the bags to the bagging machine in fixed cycles requires particular accuracy. In other words, even if a bag supply error occurs, the supply operation of the packaged items continues regardless of the error, and in such a case, confusion occurs in the packaging operation. Conventionally, vacuum suction cups have been widely used to catch thin bags accurately, but bag loading errors are most likely to occur due to the effects of static electricity and vacuum suction between each bag at the bag loading station. This is to ensure that one bag is instantaneously separated from other bags by cutting. In other words, if you use a suction cup to try to separate the outermost bag of stacked bags from the other bags in the surface direction, negative pressure will be created between the bags if the bag has a relatively large area, and a large vacuum suction force will be applied. On the other hand, the effects of static electricity also overlap, making it easy for a catch error to occur. Therefore, for example,
As shown in Publication No. 52170, if you first bend only the ends of the bags apart, allow air to enter between the bags, and then move the entire bag, the vacuum suction force will increase. It is also known that it is less susceptible to the effects of static electricity.

袋を確実に開口させる保償機能を備えていない。(Problem to be Solved by the Invention) However, when the bag is taken out from the loading station and fed to the bagging machine, the items to be packaged will spill out of the bag unless it is opened reliably even there. Although the above-mentioned known devices solve the problem of reliably removing the bags one by one from the loading station, they do not provide a guarantee function to ensure that the bags are opened in the bagging machine.

用が開始される。 On the other hand, FIG. 3 shows the chambers 13 and 1 on the piston rod side.
5 is in a state where the suction force of the vacuum pump 18 is acting on the piston rods 7 and 9, so that the piston rods 7 and 9 are pulled out against the tensile forces of the springs 19 and 20, respectively. In this case, the second air cylinder 12 is displaced by the stroke of the piston rod 7 of the first air cylinder, and the piston rod 9 strokes in conjunction with this displacement, so when comparing the movement of only the suction cup, the second suction cup 2 is It moves faster and in a larger amount than the first suction cup 1. When the two piston rods 7 and 9 have fully extended their forward motion, the tip surfaces of the two suction cups 1 and 2 become flush with each other as shown in FIG. 2, and attract the uppermost bag. Therefore, when the switching valve 17 in FIG. 3 is switched to the right symbol, a vacuum is applied to the chambers 14 and 16 on the side opposite to the rod. As explained earlier, the second air cylinder 1
Since the stroke action of the piston rod 9 is synergistic with the overall displacement movement of the piston rod 2, the second suction cup 2 precedes the first suction cup 1 even when the piston moves back as shown in FIG. Therefore, the end of the uppermost bag A is lifted first and a gap is formed between it and the lower bag to allow air to flow in. As a result, the vacuum suction force between the upper and lower bags is removed, and the uppermost bag A is smoothly lifted up by the first suction cup 1. Note that, due to the advance action of the second suction cup 2, the opening of the bag A is automatically separated from this suction cup 2. Thereafter, the two cylinders rotate as shown by the imaginary lines in FIG. 2, and through this state, the end of bag A is inserted between the two suction bars 31 and 33 of the bag filling machine as shown in FIG. A plate piece 38 is fixed in advance to the top surface of the first suction cup 1, and the tip of the plate protrudes slightly from the suction cup so that the waist of the bag A is bent.
It can be inserted between 1 and 33 without being hooked. Next, the switching valve 17 in FIG. 3 is switched, and the two piston rods 7, 9 are pushed out again. In this case, the shoulder 8a of the connector 8 pushes the movable suction bar 33 as shown in FIG. 31 and 33 respectively. Next, when the switching valve 17 in FIG. 3 is switched to the right symbol, the two suction cups 1 and 2 are separated from the bagging machine as shown in FIG. Also in this case, since the second suction cup 2 is in the lead, a gap is formed at the mouth of the bag A through which air flows. And two air cylinders 1
1 and 12 return to the state shown in FIG. 2 and wait for the next operation. On the other hand, when the space between the two suction bars 31 and 33 is opened by the rod 32 as shown in FIG. 1, the bag A attracted by these suction bars is opened and the article to be packaged is supplied from above. There are two bags filled with items to be packaged.Suction bar 3
1 and 33, and when a new suction bar is moved there, the bag feeding action is started again.

が達成されるのである。 Although the bag filling machine of the embodiment has a structure in which the bag A is supported by two suction bars 31 and 33, it is also applicable to a type of bag filling machine in which both sides of the bag are supported by clamping claws. . The point is that the intended purpose is achieved by placing the second suction cup 2 ahead of the first suction cup 1 both when the piston rod moves forward and backward.

る。(Effects) As described above, the bag feeding device of the present invention fixes the first suction cup 1 to the tip of the piston rod of the first air cylinder 11, and fixes the second air cylinder 12 to the piston rod via the connector 8. A second suction cup 2 is attached to the tip of the piston rod of the second air cylinder.
furthermore, each piston of both cylinders 11 and 12 is connected to a bag loading station 21.
Since the fluid circuit is configured so that the and bagging machine 22 perform reciprocating motion, the stroke of the second suction cup 2 itself is different from the movement of the second air cylinder 12 that is synchronized with the stroke movement of the first suction cup 1. As a result, the second suction cup 2 is attached to the first suction cup at the bag loading station 21 and the bag filling machine 22, respectively.
This precedes suction cup 1, and with this precedence function, the edges of the bag sucked by each suction cup in both positions are automatically bent to form an air inflow gap, so one supply The bag device also has the effect of accurately feeding bags so that bag catching errors and bag opening errors do not occur.
