【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1, FIG. 2 and FIG. 3 show an embodiment of a bag body mounting device for a box body such as a corrugated box according to the present invention.

A bag body mounting device for a box body such as a corrugated board box according to the present invention comprises a holding device 201 for a packaging container a such as a corrugated board box, and a bag body inserting device 202 (see FIGS. 1 to 3). Does not appear). Further, in this embodiment, the bag body mounting device is provided with a transfer means 300 for the packaging container a 1.

The packaging container a such as a corrugated cardboard box held by the holding device 201 is a box body formed in a substantially rectangular parallelepiped shape, and its upper surface is opened and four sides forming the periphery of the opening are respectively provided. The sealing pieces c that seal the openings by folding are provided upright (FIG. 22).

The holding device 201 holds the packaging container a supplied from the other by the transfer means 300 in a fixed position. On the other hand, the bag body inserting device 202 is for inserting the bag b into the packaging container a held at a fixed position, and the bag b to be inserted is at the tip of each of the sealing pieces c ... Before being folded. When the periphery of the bag mouth is hooked, everything that is put into the box from the opening of the packaging container a is accommodated in the bag b through the bag mouth, and the contents are packaged in the packaging container a. It can be included in b (Fig. 24).

Further, the holding device 201 has at least two contact portions, a first contact portion 211 and a second contact portion 212, capable of holding the box body at least when the bag body is inserted. It has a contact part. The first contact portion 211 and the second contact portion 212 at least when the box body is sandwiched, the side edges of the respective sealing pieces c ... Adjacent to the box body contact or approach each other. It has a holding part 213, which maintains the state, that is, restricts the opening of each sealing piece in the direction opposite to the direction in which the opening of the packaging container a is sealed. Hereinafter, each configuration of the holding device 201 will be described in detail.

The first contact portion 211 is formed in a plate shape, and is arranged substantially horizontally along the transfer direction X of the packaging container a. The surface 211a of the first abutting portion 211 faces the side of the packaging container a and is provided with pressing portions 213 and 213 which will be described in detail later.

The back surface 211 b of the first contact portion 211 is fixed to the tip of the actuator 221. Reference numeral 231 in FIGS. 1 to 3 indicates a connecting portion between the tip of the actuator 221 and the first contact portion 211. Further, 231a ... Show a connecting hand of the connecting portion 231. The cylinder 241 of the actuator 221 is fixed to the cylinder fixing portion 251. Guide bars 261 and 261 are loosely fitted in the cylinder fixing portion 251, and the guide bars 261 and 261 can slide in the longitudinal direction of the cylinder fixing portion 251. The tips of the two guide bars 261 and 261 are fixed to the back surface 211b of the first contact portion 211 via the coupling portion 231, like the tips of the actuator 221. A contact member 271 is fixed to the rear ends of both guide bars 261 and 261. As the actuator 221 expands and contracts, the guide bars 261 and 261 which are loosely fitted in the cylinder fixing portion 251 also slide, thereby guiding the actuator 221 to slide. The hitting member 271 hits the direction in which the actuator 221 and the guide bars 261 and 261 extend, and restricts sliding more than that.

The cylinder fixing portion 251 is fixed to the structural member 400 of the apparatus main body according to the present invention via the height adjusting member 281. The height adjusting member 281 is capable of adjusting the height of the structural member 400 in the height direction, and by adopting an appropriate known procedure, the cylinder fixing portion 251 can be moved in the Z direction of FIG. It is possible to adjust the position. That is, this is to adjust the height of the first contact portion 211 supported by the actuator 221 by enabling the height adjustment of the cylinder fixing portion 251. If unnecessary, it is possible to carry out without providing such a height adjusting member 281.

The second contact portion 212 is formed in a plate shape like the first contact portion 211, and at a position facing the first contact portion 211, as shown in FIGS. 1 and 3. The packaging container a is arranged substantially horizontally along the transfer direction X and substantially parallel to the first contact portion 211. The surface 212a of the second contact portion 212 faces the side portion of the packaging container a, and like the first contact portion 211, the holding portions 213 and 213 described in detail later are provided.

In this embodiment, unlike the first contact part 211, the second contact part 212 does not fix the back surface 212b directly to the tip of the actuator 222 but to the height adjusting member 282. It is fixed to the tip of the actuator 222 via the height adjusting member 282. That is, the height adjusting member 282 is responsible for the connection between the tip of the actuator 222 and the back surface 212b of the second contact portion 212, similarly to the coupling portion 231 of the first contact portion 211. This height adjusting member 282, like the height adjusting member 281 provided on the side of the first contact portion 211, enables position adjustment in the Z direction, and employs any suitable means known in the art. It should be carried out. If this height adjusting member 282 is also unnecessary, it can be carried out without providing it.

The cylinder 242 of the actuator 222 is fixed to the cylinder fixing portion 252. Guide bars 262 and 262 are loosely fitted in the cylinder fixing portion 252, and the guide bars 262 and 262 are slidable in the longitudinal direction of the cylinder fixing portion 251. A contact member 272 is fixed to the rear ends of both guide bars 262 and 262. As the actuator 221 expands and contracts, the guide bars 262 and 262 that are loosely fitted in the cylinder fixing portion 252 also slide, thereby guiding the actuator 222 to slide. The hitting member 272 hits the actuator 222 and the guide bars 262 and 262 in the extending direction, and further restricts sliding.

The above-mentioned first contact portion 211 and second contact portion 212 are both in contact with the side surface of the packaging container a sent from the transfer means 300 by the above sliding of the actuators 221, 222. It comes into contact. The spotted portion in FIG. 2 indicates a portion where such a sliding operation (in the Y direction) is performed. These series of operations will be described in detail later.

Next, with reference to FIGS. 4, 5, 6, 7, and 8, the pressing portions 213 ... Which the first contact portion 211 and the second contact portion 212 have will be described. Since the pressing portions 213 of the first abutting portion 211 and the second abutting portion 212 have the same configuration, a configuration other than the pressing portions 213 shown in FIGS. 4, 5 and 8 is used. The members are both the first contact portion 211 and the second contact portion 212 (in these figures, the member numbers of the first contact portion 211 and the second contact portion 212 are also shown). As shown in FIGS. 3 and 6, two pressing portions 213 are provided before and after the surface 211a of the first contact portion 211, and two before and after the surface 212a of the second contact portion 212, respectively. , The surface 211a of the first contact portion 211 and the surface 212a of the second contact portion 212. Then, as shown in FIGS. 4 and 6, each pressing portion 213 has a guide surface 213a. The guide surface 213a is a flat surface or a curved surface that inclines from the base portion of the pressing portion 213 to the tip thereof. The example illustrated in FIG. 4 is formed as a surface having an appropriate radius. It is also possible to adopt another curved surface or a flat surface to form the guide surface 213a. As shown in FIG. 6, the two pressing portions 213 and 213 provided on one of the contact portions are arranged so that their guide surfaces 213a face each other. The distance between the guide surfaces 213a, 213a of the pair of front and rear pressing portions 213, 213 provided on one contact portion has the same length as the front-back width of the packaging container a. As shown in FIG. 8, each of the guide surfaces 213a faces a corner f formed by the sealing pieces c and c of the packaging container a such as a corrugated cardboard box which are adjacent to each other. Then, the first contact portion 211 and the second contact portion 212 slide in the Y direction (FIG. 3) by the actuators 221 and 222, so that the guide surface 213a is on the guide surface 213a and the tip of the pressing portion 213. From the side to the base side of the pressing portion 213, a sealing piece c located at a position facing the traveling direction of the packaging container a (the traveling direction of the packaging container a in FIG. 8 is the leftward direction in the drawing). Guide and press the sealing piece c in the position facing the back (Fig. 6, Fig. 7). At the same time, the sealing piece c facing the first contact portion 211 side is on the surface 211a of the first contact portion 211, and the sealing piece c facing the second contact portion 212 side is on the surface 212a of the second contact portion 212. Is pressed by. At this time, the adjacent sealing pieces c bring side edges g and g (FIG. 6) close to the base end side 213b of the pressing portion 213 to form a corner f or hold it (FIG. 7). ). Of course, the positions where the side edges g, g (FIG. 6) are brought close to each other to form the corner f are not limited to those set on the base end edge 213b of the pressing portion 213, and the guide surface 213a of the pressing portion 213 is not limited to this. It is also possible to implement it by forming the corner f by bringing the side edges g and g (FIG. 6) closer to each other at another position above. In this case, the sealing pieces c, c facing the abutting portions 211, 212 are not the abutting portions 211, 212 but the guide pieces c, c located before and after the packaging container a in the traveling direction. The surface 213a brings them together to form the corner f. Further, in this case, when the stopped position of the packaging container a to be transferred (the transfer operation of the packaging container a will be described in detail later) is slightly deviated from the proper position to the front or back, Even when the front-rear dimension of the container a is larger than a predetermined size, the guide surfaces 213a of the pressing portions 213 are guided and corrected to proper positions without any trouble, or both contact portions 211 and 212 are properly adjusted. Sandwiched by. As shown in FIG. 8, the pressing portions 213 are arranged at positions where they come into contact with the vicinity of the base of the sealing pieces c. This is because when the sealing pieces c are arranged so as to press near the upper end, the pressing portions 213 do not get in the way when the opening peripheral edge of the bag b is hooked on the sealing pieces c. It is more effective if the upper and lower positions of the pressing portions 213 ... Can be adjusted. This can be implemented by adopting an appropriate structure in which the pressing portions 213 ... Can move up and down relative to the contact portion (not shown). Needless to say, the height adjusting members 281 and 282 of the contact portions 211 and 212 can adjust the vertical position of the first contact portion 211 and the second contact portion 212 without providing a separate adjusting means. It is possible.

As described above, the distance between the guide surfaces 213a, 213a of the pair of front and rear pressing portions 213, 213 provided on one contact portion has the same length as the front-back width of the packaging container a. However, in order to cope with the change in the size of the packaging container a to be handled, it is desirable to adopt the following position adjusting means of the pressing portion 213. More specifically, as shown in FIG. 4, a groove 214 extending in the longitudinal direction of the abutting portions is provided at the portion where the pressing portions 213 of the abutting portions 211 and 212 are provided. Then, in the groove 214, a long hole 214a is provided which makes the longitudinal direction equal to that of the groove 214. The elongated hole 214a penetrates from the front surface 211a (212a) side of the contact portion to the rear surface 211b (212b) side (FIGS. 4 and 5). The holding portion 213 is formed separately from the abutting portion, and the base bottom surface 213c is provided with a screw hole or a tap (not shown in order to avoid complication of the drawing), a bolt, a nut, or the like. The fastener 213d is screwed into the screw hole or tap from the back surface 211b (212b) side of the contact portion, and the pressing portion 213 is fixed to the groove 214. At this time, if the head portion of the fastener 213d (the portion of the contact portion projecting to the back surface 211b (212b) side) has a sufficient size, it will not fall into the elongated hole 214a. Also, in the case where it is not, as shown in FIG. 5, it is possible to deal with it by providing the head with a catching means 213e such as a collar or a washer. The pressing portion 213 configured as described above is fixed to the contact portion by arranging it at a desired position in the groove 214 and tightening the fastener 213d.

If only the minute adjustment is intended, the groove 214 has a relatively short longitudinal width, and four grooves are provided corresponding to the number of the holding portions 213, 213, 213, 213. You can leave it. That is, two may be provided on the front surface 211a of the first contact portion 211, and two on the front surface 212a of the second contact portion 212. In this case, if it is unnecessary, it is possible to provide only one groove 214 for one contact portion and fix the other holding portion 213. However, in this case, the fixed pressing portion 213 of the first contact portion 211 and the fixed pressing portion 213 of the second contact portion 212 need to be arranged at positions facing each other. If it is unnecessary, the pressing portion 213 may be completely fixed to the abutting portion without the position adjusting means as described above.

Although not shown in the drawings, the pressing portion 213 in the above-described embodiment receives the supply of appropriate dynamic force from the other, and the first contact portion 211 and the second contact portion 212 (see FIG. 3). (Shown) In synchronism with sliding in the Y direction, it automatically slides on both contact surface 211a, 212a (sliding in the direction orthogonal to the Y direction), and the packaging container a It is also possible to embody the present invention by pressing the respective sealing pieces c ... In this case, the guide surface 213a of the pressing portion 213 does not need to be the inclined surface as described above.

Next, the operation of each of the above parts will be collectively described. 9, 10 and 11 sequentially show the above-described series of operations. First, as shown in FIG. 9, the transfer container 300 such as a belt conveyor transfers the packaging container a to a position where the holding device 201 is present more than others. At a certain position of the holding device 201, the transfer means 300 has a contact member 301 in order to reliably stop the packaging container a being sent. More specifically, when the belt conveyor is adopted as the transfer means 300, at a certain position of the holding device 201, the transfer section of the belt conveyor is constituted by the left transfer section 311 and the right transfer section 312, and the transfer section is separated into right and left. It is in a state. That is, the left transfer unit 311 and the right transfer unit 312 are arranged in parallel in the left and right at appropriate intervals, and the left transfer unit 311 and the right transfer unit 312 form one transfer unit and work together. Then, the packaging container a is transferred. In this way, the contact member 301 is arranged in the gap between the left transfer portion 311 and the right transfer portion 312 formed. The hitting member 301 can be moved up and down by an appropriate means (not shown), and normally stays downward and does not project upward from the surface of the transfer section formed by the left transfer section 311 and the right transfer section 312. is there. Then, when the packaging container a is sent to a desired position, that is, a position where the first contact portion 211 and the second contact portion 212 of the holding device 201 are located, the packaging container a moves upward and is moved to the left transfer portion 311 and the right transfer portion 311. It projects from the surface of the transfer section formed by the section 312 and comes into contact with the front of the sent packaging container a to prevent the packaging container a from advancing. At this time, by the operation of the first contact portion 211 and the second contact portion 212 of the holding device 201 described above, the packaging container a is provided between the first contact portion 211 and the second contact portion 212. The holding pieces 213, 213, 213 of the first contact portion 211 and the second contact portion 212 are held so that the sealing pieces c, c, c, c of the packaging container a do not spread. , 213.

In this way, as shown in FIG. 10, the bag inserting device 202 inserts the bag b into the packaging container a held at the predetermined position from above. Then, the periphery of the opening of the inserted bag b is hooked on the sealing pieces c, c, c, c of the packaging container a. As the bag body inserting device 202, any conventionally known device may be adopted as long as the bag b can be inserted into the packaging container a by such an operation, and an appropriate device thereof can be adopted. Will be exemplified later.

After the bag b is attached, as shown in FIG. 11, the hitting member 301 descends and returns to the position where it does not project from the surface of the transfer section formed by the left transfer section 311 and the right transfer section 312. After that, the left transfer unit 311 and the right transfer unit 312, which have stopped during the mounting of the bag b, restart the transfer and transfer the packaging container a to the front. By such a series of operations, the bag b is properly and automatically attached to a large number of packaging containers a.

The bag insertion device 202 described above will be described by exemplifying a suitable one. However, the bag body inserting device 202 is not limited to the one described here, and it is also possible to adopt and implement one having another configuration.

FIG. 12 and FIG. 13 are perspective views showing an outline of the bag body inserting device 202 of the above embodiment, that is, a means for hanging an inner bag on a packaging container. The bag body inserting device 202 is inserted into an opened bag and inserts the bag into a container, and four locking members 2 arranged above the insert body. And a moving means (shown in FIG. 14) for inserting the insert into a packaging container a such as a cardboard box. The packaging container a is placed on the transfer surface 3 of the transfer means 300 such as a belt conveyor arranged below the insert 1, is sequentially transferred, and temporarily stops below the insert 1. The insert 1 is lowered by the moving means, and a bag made of synthetic resin is placed inside the packaging container a.

FIG. 14 is a side view showing moving means for moving the above-mentioned insert 1 up and down. This moving means moves the insert 1 up and down by two air cylinders, a first air cylinder 4 and a second air cylinder 5. First, the first air cylinder 4 is moved up and down by the expansion and contraction of the piston vertically arranged on the main body of the apparatus (not shown), and the guide shaft 6 is used to properly move it up and down. Be guided. An arm 7 extends forward from the first air cylinder 4, and a support plate 8 hangs from the tip of the arm 7. A second air cylinder 5 is vertically arranged along the support plate 8. The bottom of the insert 1 is attached to the second air cylinder 5. Therefore, the insert 1 moves up and down as the second air cylinder 5 expands and contracts, and the second air cylinder 5 and the insert 1 both move up and down as the first air cylinder 4 expands and contracts. Although not shown, an appropriate guide shaft may be provided in order to raise and lower the insert 1 accurately by expanding and contracting the second air cylinder 5. Two air cylinders are used for raising and lowering the insert 1 in order to move the insert 1 up and down over a length greater than the length of the piston rod of each air cylinder. The insert 1 may be moved up and down only by the dam, or the insert 1 may be moved up and down by another drive source such as an electric motor.

Next, the configuration of the insert 1 will be described in more detail with reference to FIGS. 15 and 16. FIG. 15 is a front view of the insert, the right half of which is drawn partially in section. FIG. 16 is a plan view of the insert. In this insert 1, four pillars 11 are arranged at four corners, a bottom portion 12 is arranged at the lower ends of the four pillars 11, a top portion 13 is arranged at the upper end thereof, and an intermediate portion 14 is arranged between them. It is ranked. The upper and lower ends of the columns 11 are fixed to the bottom 12 and the top 13, respectively, and the intermediate part 14 is slidable in the vertical direction with respect to these columns 11.

The locking members 2 are attached to the four corners of the intermediate portion 14. Note that FIG. 15 shows only one of the right ends. The locking member 2 is composed of a vertically long rod-shaped body, and a roller 15 is attached to the lower end thereof. An upper end of the locking member 2 is rotatably attached to the intermediate portion 14 via a rotary shaft 16, and an air cylinder for expansion is attached to the upper end of the locking member 2 via a rotary shaft 17. Eighteen piston rod tips are attached. The enlargement air cylinder 18 itself is mounted on the intermediate portion 14 so that the angle can be adjusted. Therefore, when the piston rod of the expanding air cylinder 18 contracts, the locking member 2 rotates about the rotating shaft 16 as a fulcrum, and the lower end thereof expands outward.

As described above, the intermediate portion 14 is slidably attached to the column 11, and is moved up and down by the sliding air cylinder 21. The sliding air cylinder 21 is arranged below the intermediate portion 14, and the expansion and contraction of the piston rod moves the intermediate portion 14 and the locking member 2 attached thereto up and down.

The left and right ends of the bottom end of the sliding air cylinder 21 are supported by guide shafts 22, 22 arranged between the bottom 12 and the top 13, and female screw holes 23 are formed. ing. A screw shaft 24 is screwed into the female screw hole 23, the lower end of the screw shaft 24 is rotatably supported by the bottom portion 13, and the upper end thereof is rotatably supported by the top portion 15. Moreover, the hand-turning member 25 is attached to the end of the hand-operated member 25 so as to project upward. Therefore, by rotating the hand-turning member 25, the screw shaft 24 rotates, and the rotation causes the sliding air cylinder 21 to move up and down. It should be noted that, instead of manually turning, it can be rotated by other means such as an electric motor, and the sliding air cylinder 21 may be moved up and down by a cylinder or the like. In this way, by vertically moving the sliding air cylinder 21, the vertical positions of the intermediate portion 14 and the locking member 2 attached to the piston rod can also be adjusted.

Next, as shown in FIG. 16, the four columns of the insert 1 can be moved forward and sideward. As described above, the bottom portion 12 is arranged at the lower ends of the four pillars 11, the top portion 13 is arranged at the upper end thereof, and the intermediate portion 14 is arranged between them, respectively. Each of the portion 13 and the intermediate portion 14 slidably supports the column 11 in the front and side directions, and the position of the column 11 can be adjusted by this sliding.

This concrete configuration will be described in more detail with reference to FIG. 16. The top portion 13 shown in FIG. 16 includes a center plate 31, a left frame portion 32, a right frame portion 33, and a front frame portion 34. And the front frame portion 34 is composed of a left front frame portion 35 and a right front frame portion 36. The central plate 31 has a left insertion portion 37 and a right insertion portion 38 extending on both left and right sides. The left and right insertion portions 37, 38 are respectively inserted in the left frame portion 32 and the right frame portion 33 so as to be slidable in the left and right directions. From the left end of the left front frame part 35 of the front frame part 34 and the right end of the right front frame part 36, rear insertion parts 39 and 40 are respectively extended rearward. The rear insertion portions 39 and 40 are respectively inserted in the left frame portion 32 and the right frame portion 33 so as to be slidable in the front-rear direction. A front insertion portion 41 extends from the left end of the right front frame portion 36. The front insertion portion 41 is slidably inserted in the left front frame portion 35 in the left-right direction.

Therefore, when the left frame part 32 and the left front frame part 35 are pulled to the left, the left insertion part 37 and the front insertion part 41 slide, and the left frame part 32 and the left front frame part 35 are separated from each other. , Can extend to the left. Similarly, the trunk frame portion 33 and the right front frame portion 36 can extend rightward. Further, when the front frame portion 34 is pulled forward, the rear insertion portions 39 and 40 slide, and the front frame portion 34 can extend forward. This extended state is shown by a two-dot chain line in FIG. Since the support columns 11 are fixed to the corners of the frame portions 32, 33, and 34, the position of the support columns can be changed as the frame portions expand and contract.

Although not shown, the bottom portion 12 has the same structure as that of the top portion 11, and the middle portion 14 is different only in that the column 11 slidably penetrates. Other configurations are similar to those of the top portion 11. Therefore, the column 11 can move laterally as the bottom part 12, the top part 13, and the intermediate part 14 expand and contract while maintaining the vertical state. Thereby, the lateral position of the locking member 2 attached to the intermediate portion 14 can also be adjusted. Although not shown, the position after the movement can be fixed by the structure of the long hole, the bolt and the nut, and the position may be automatically moved by the piston and the gear.

Next, the operating state of this device will be described. This device is used to hang a bag b made of synthetic resin or the like inside a packaging container a. As a step before reaching this device, the bags are continuous as shown in FIG. The sheet is sent in a sheet state, supported by a pair of front and rear vacuum frames 101, 101, and cut by a cutter 102 for each bag. To explain step by step, the bag b sent in the sheet state is passed between the open vacuum frames 101 and 101 as shown in FIG. 13 (in FIG. 13, the insert 1 is lowered). Although it is drawn in the state, the insert has not actually descended yet). After that, as shown in FIG. 12, the vacuum frames 101, 101 are closed, and the bag is adsorbed to the respective vacuum ports 103. Then, as shown in FIG. 17, each bag is cut by the cutter 102. Thereafter, the vacuum frames 101, 101 are opened back and forth again as shown in FIG. 13, so that the mouth of the bag is opened in a rectangular shape. At this time, the packaging container a is placed on the transfer surface 3 of the transfer means 300 such as a belt conveyor and stopped below the bag b by the holding means 201. From this state, the operation of the device of the present application starts (in FIG. 13, the insert 1 is depicted as being lowered, but in reality, the insert is not yet lowered). Although the number of the vacuum ports 103 of the vacuum frames 101, 101 is arbitrary, two vacuum ports 103 are provided for each vacuum frame 101, that is, four vacuum ports 103 in total. The shape is also free, but it is preferable to make it vertically long for more reliable support of the bag.

Hereinafter, the operating state of the bag inserting device 202 will be described with reference to FIGS. 18 to 21. 18 to 21, the vacuum frame 101, the first air cylinder 4 and the second air cylinder 5 are omitted in the following text. The insert 1 is inserted into the bag b opened by the vacuum frames 101, 101 (FIG. 18). In this state, each locking member 2 is raised and is along the support 1 without being enlarged. The first air cylinder 4 extends and the insert 1 starts to descend. Then, in a state where the lower half of the insert 1 is inserted into the bag b, the sliding air cylinder 21 is contracted and the intermediate portion 14 and the expanding air cylinder 18 and the locking member 2 provided therein are provided. Goes down. Then, the enlarging air cylinder 18 contracts, the respective locking members 2 expand outward, and the mouth of the bag b is locked from the inside (FIG. 19). The second air cylinder 5 is extended, the insert 1 is lowered as it is, and the bag b is held by the holding means 201 (omitted to avoid complicating the drawing in FIG. 18). It is inserted in a. At this time, since the lower end of the locking member 2 is expanded outward, the locking member 2 follows the outside of the side wall of the packaging container as the insert 1 descends. As a result, the mouth of the bag b is folded back using the upper end of the side wall of the packaging container as a fulcrum, and the inner bag hanging on the packaging container is completed (FIG. 20). The insert 1 rises (FIG. 21) and returns to the state of.

In the above process, after the locking member 2 is lowered by the action of the sliding air cylinder 21, each locking member 2 is expanded outward by the action of the expanding air cylinder 18. However, in the step, each locking member 2 is expanded outward by the action of the air cylinder 18 for expansion so as to lock the bag, and in the step, the bag b is inserted into the packaging container a and then slid. It is also possible to lower the locking member 2 by the action of the moving air cylinder 21 so that the mouth of the folded bag b is folded deeper to the outside of the packaging container a.

Further, in the present invention, since the size and the position of the insert 1 and the locking member 2 can be adjusted, the inside of the bag and the packaging container can be satisfactorily adjusted even if the size and depth of the bag and the packaging container are changed. Bagging can be done. Regarding the size of the mouth of the bag, as described above, the frame portions of the bottom portion 12, the top portion 13 and the intermediate portion 14 are extended leftward or rightward and the columns 11 are moved leftward or rightward. . As a result, the position of each locking member 2 provided in the intermediate portion 14 also changes, and it is possible to handle a bag having a wider mouth. The enlargement position of each locking member 2 is adjusted and changed by adjusting the stroke of the air cylinder 18 for enlargement or adjusting the length of the piston rod. Therefore, it is possible to carry out only by such adjusting means. However, for major changes, it is advantageous to change the position of the column 11, etc., and by changing the position of the column 11, etc., the size of the entire insert 1 can be adjusted, so it is more reliable. Various insertion work becomes possible.

Regarding the depth of the bag, as described above, by rotating the screw shaft 24 and moving the sliding air cylinder 21 up and down, the upper and lower portions of the intermediate portion 14 and the locking member 2 attached to the piston rod are moved up and down. The position can also be adjusted. Therefore, the length between the locking member 2 and the bottom portion 12 of the insert 1 can be adjusted, and a bag having different depths can be accommodated.

Incidentally, instead of or in combination with such adjusting means, by providing a connecting member (not shown) on the bottom portion 12 of the insert body 1, a space between the locking member 2 and the lower end of the insert body 1 is provided. The length of may be adjusted.
