Description

[Detailed explanation of the invention] <Industrial field of application> This invention is mainly used in sewing factories for the so-called tensioning of double jackets, and for other purposes such as sewing a bag-like bag with string, etc. after sewing it inside out into a bag-like shape. This invention relates to a bag-like object reversing device used to turn it over to the front side.

<Prior art and its problems> When sewing an elongated bag-like object (one end of which is closed and the cross section is elongated and has a U-shape) turned inside out and then turned over to the front side, conventionally, a worker has to manually sew the object one by one. It was flipped completely by hand.

However, this work is much more time-consuming than expected, and although it may seem easy to an experienced person, in reality it requires a great deal of patience. In addition, in a sewing factory, sewing work cannot flow smoothly unless each process is performed at the same time interval, and since reversing a bag-like item takes time, it can disrupt this flow. There is.

<Means for solving the problem> In other words, it is possible to easily reverse the bag-like object, thereby reducing the burden on the worker, and also making it possible to perform the reversing work in the same amount of time as other tasks. It is necessary to do so.

Therefore, in order to solve the above-mentioned problems, the bag reversing device according to the present invention has a pusher rod which is placed opposite to the hollow bag set pipe with a slight interval therebetween, and which can be inserted into the hollow bag set pipe. is arranged to be movable up and down, and after setting the bag to cover the bag-like article setting pipe, the bag-like article can be turned over simply by moving the pushing rod up and down to insert the push rod into the bag-like article setting pipe. This is how it was done.

<Embodiment> Next, an embodiment of the bag-like object reversing device according to this invention will be described based on the drawings. Reference numerals 1 and 2 are hollow bag-like object setting pipes, It is arranged vertically. In the illustrated embodiment, two bag-like material setting pipes 1 and 2 are provided, but the number is not particularly critical, and it may be one or three or more. The lower surface of the slide table 3 is a sliding groove 6 of a fixed slide rail 5 arranged on the device table 4.
It is configured to fit and be slidable.

Reference numeral 7 denotes an air cylinder, which is arranged so that an extendable push-in rod 9 faces downward with respect to a column 8 which is arranged perpendicularly to the apparatus stand 4. The air cylinder 7 is placed at a position where the pushing rod 9 can be inserted into the bag-like object setting pipes 1 and 2, and where a slight gap is created between the upper ends of the bag-like object setting pipes 1 and 2 when the pushing rod 9 is contracted. It is arranged.
An air hose 10 is connected to the air cylinder 7, and is connected to an air pressure source (not shown) via a control valve 11. Reference numerals 12 and 13 indicate limit switches disposed at the ends of the slide rail 5, and when the slide base 3 moves and the ends come into contact with each other, the bag-like object setting pipes 1 and 2 are placed in a position facing the push rod 9. detects that it is located at
The control valve 11 is opened to operate the air cylinder 7.

Reference numerals 14 and 15 indicate air hoses that enter from the side surface of the slide table 3 and are connected to the lower end surfaces of the bag-like material setting pipes 1 and 2, respectively, and control valves 16 and 1.
7 to a pneumatic source (not shown). The control valve 16 is opened when the end of the slide base 3 comes into contact with the limit switch 13. Further, the control valve 17 is opened when the end of the slide base 3 comes into contact with the limit switch 12.

<Function> Then, the bag-like object 18 which has been sewn inside out and has not yet been turned inside out is placed over the bag-like object set pipe 1 while being turned inside out. Then, the slide table 3 is slid so that the bag-like material setting pipe 1 is in a position facing the push-in rod 9. Then, the end of the slide base 3 comes into contact with the limit switch 12, and
The control valve 11 is opened and the air cylinder 7
is activated, the pushing rod 9 moves downward and pushes the bottom of the bag-like article 18, and the other part of the bag-like article 18 is turned over (turned inside out) by the upper edge of the bag-like article set pipe 1 and the bag is folded. The shaped object 18 is pushed into the bag-like object set pipe 1. When the pushing rod 9 is fully extended, the bag 18 is completely inverted inside the bag set pipe 1. Here, if the air cylinder 7 is a double-acting type, the air cylinder 7 will automatically retract after being fully extended, which will simplify the work. On the other hand, at this point, the other bag-like article setting pipe 2 is covered with the bag-like article 18 which has been sewn and has not yet been turned over, and preparations are made to turn it over.

Next, the push-in rod 9 is raised and pulled out from the bag-like article set pipe 1. In this case, the control valve 16 is opened at the same time, air is blown from below the bag setting pipe 1, and the bag which is in an inverted state (turned face up) inside the bag setting pipe 1 is opened. The object 18 will be automatically taken out by air pressure. When the bag-like object 18 comes out, the control valve 16 is automatically closed. Then, the slide table 3 is slid in the opposite direction so that the bag-like object setting pipe 2 is in a position facing the push-in rod 9. Then, at this point, the end of the slide table 3 comes into contact with the limit switch 13, the control valve 11 is opened in the same manner as described above, the air cylinder 7 is operated, and the push rod 9 moves the bag-like article 18 into the bag-like article set pipe 1. descend while pushing it into the When the pushing rod 9 is fully extended, the bag 18 is inverted inside the bag set pipe 1. Also,
At the same time, the control valve 17 is opened, air is blown from below the bag-like object setting pipe 2, and the bag-like object 18, which is in an inverted state (turned face up) in the bag-like object setting pipe 2, is It will be automatically taken out by air pressure. Bag-like item 18
The control valve 17 is set to close automatically when the gas comes out. Thereafter, the bag-like article 18 that has already been sewn before being turned over is placed on the other bag-like article setting pipe 1, and preparations are made for turning it over.

Then, by sliding the slide table 3 again so that the bag-like object setting pipe 1 is in a position facing the push-in rod 9, the bag-like object 18 can be inverted and taken out by simply sliding the slide table 3 from side to side. The work can be done automatically.

<Effects of the invention> As described above, according to the bag reversing device according to the invention, the bag can be inserted into the hollow bag setting pipe by facing the hollow bag setting pipe with a slight gap between them. Since the push rod is arranged to be able to move up and down, the bag can be turned over simply by placing the bag over the bag set pipe and moving the push rod up and down, making the work easier. At the same time, it is possible to speed up the reversing work. Also,
If a detection device is installed in the bag-like article setting pipe to detect when a bag-like article is set, and the air cylinder is automatically operated when the bag-like article is detected, then all you have to do is slide the slide table left and right. Its practical effects are extremely large, such as being able to automatically perform the reversing process.
