In the bag holding apparatus for inserting the contents into the encapsulation while conveying the encapsulation and the contents to suction conveyors arranged in parallel with each other, in order to accurately synchronize the conveying speed of the encapsulation and the contents, the encapsulation apparatus travels along the rotation of the timing pulley. It is preferable to apply a timing belt as a belt of a suction conveyor.

FIG. 13 has shown the structure which supports the timing belt 105 which provided the tooth 103 in the edge part 101 of the both sides of the width direction with the support member 107 (refer patent document 2). In view of miniaturizing the suction conveyor, the timing belt 105 is required to be thin in thickness. In addition, the support surface 109 of the support member 107 receives the load of the article so that the timing belt 105 does not bend under the load of the article loaded on the timing belt 105.

However, the width of the groove 113 for guiding the negative pressure to the vent hole 111 of the timing belt 105 is limited by securing the support surface 109 to the support member 107. The arrangement and the width of the vent holes 111 are also limited. This is disadvantageous in that the vent hole 111 increases the suction force for sucking the article. In addition, since the branch path 115 for distributing the negative pressure to the plurality of grooves 113 is indispensable, there is a problem in miniaturization of the suction conveyor.

SUMMARY OF THE INVENTION An object of the present invention is to provide a timing belt, an airtight structure of a suction conveyor, and a bag holding device, which can satisfactorily suck an article and contribute to miniaturization of the suction conveyor.

The present invention is a timing belt in which a plurality of teeth arranged in the longitudinal direction are provided in a belt body through which vent holes penetrate between edge portions on both sides in the width direction, and the teeth are moved inward in the width direction from the edges of the belt body. It is characterized by the arrangement.

In addition, the present invention provides a timing belt having a plurality of teeth arranged in the longitudinal direction through a ventilation hole penetrating between the edge portions on both sides in the width direction of the belt body, and inward in the width direction from the edge portion, and the timing. The bottom surface member which supports the teeth of a belt slidably in the said longitudinal direction, and the air flow path which guides a negative pressure in the said ventilation hole, extends in the said longitudinal direction, and the edge part of both sides of the said strip | belt body is each sliding contact. It is characterized by including two sets of airtight liners.

Moreover, this invention is that the said bottom face material has the guide groove which receives the teeth of the said timing belt from a bottom face, the said air path is open to the bottom face of the said guide groove, and the two sets of airtight liners are provided in the inside of the said guide groove. The teeth are spaced apart from each other at intervals passing.

In addition, the present invention is a horizontal direction of the timing belt provided with a plurality of teeth arranged in the longitudinal direction through the ventilation hole penetrates between the edge portions on both sides of the width direction of the belt body in the width direction than the edge portion. It is pushed by the suction conveyor which drives and encapsulates the encapsulation body which is taken in by the said timing belt by the negative pressure guided to the said ventilation hole, the direction which advances to the encapsulation body sucked by the said suction conveyor, and the direction which retracts from the said encapsulation body. Reciprocating movement of the, characterized in that the pusher is provided with an insertion device for pushing the article into the encapsulation in the process of advancing to the encapsulation.

In addition, the present invention is a bottom surface member which supports the teeth of the timing belt slidably, and has an air passage for guiding negative pressure in the vent hole of the timing belt, extends in the longitudinal direction of the timing belt, and the belt body of the timing belt. It is characterized by including two sets of hermetic liners in which the edge portions of both sides are in sliding contact.

In addition, the present invention is a film supply means for folding the film in the width direction in the form of a two-way overlap in the width direction during the conveyance of the film prescribed in the width direction dimensions, and a heat cutter extending in the width direction of the film of the film An altar which press-bonds in the longitudinal direction and forms the encapsulated body having an opening portion by dividing the film in the middle of the longitudinal direction while welding the two overlapping films by the heat of the heat cutter. And a device.

In the airtight structure of the timing belt and the suction conveyor according to the present invention, since teeth are provided in the width direction inward from the edge of the belt body, the edge of the belt body can be functioned as follows. That is, when the timing belt runs in the longitudinal direction in accordance with the rotation of the timing pulley, the edge portions on both sides of the belt body are in sliding contact with each of the two sets of airtight liners. Therefore, the negative pressure guided from the air passage of the bottom face material supporting the teeth to the vent hole of the timing belt is suppressed from being discharged between the edge portions on both sides of the belt body and the bottom face material, and the suction force that the air hole sucks the article placed on the band body. You can increase it.

In addition, since the teeth of the timing belt according to the present invention also serve to reinforce the inner portion of the edge portion of the belt body, even if the width of the air passage is more than half the width of the tooth width, the timing belt is driven by the load of the article placed on the belt body. It does not curve easily in the width direction. Therefore, the airtight structure of the suction conveyor is advantageous for increasing the suction force by widening the vent holes and the air passages, respectively.

Further, according to the airtight structure of the timing belt and the suction conveyor according to the present invention, due to the action of the negative pressure guided from the air passage to the vent hole of the timing belt, the area inside the belt body and the guide groove is lower than the atmospheric pressure. . Based on the pressure difference between these regions and the atmosphere, since the edge portions on both sides of the belt body are compressed by two sets of airtight liners, the airtight structure of the timing belt and the suction conveyor can achieve the above effects remarkably.

According to the bag holding apparatus according to the present invention, by setting the speed at which the pusher reciprocates, the number of articles that can be inserted into the bag per predetermined time can be easily increased. In addition, the suction conveyor can suppress the negative pressure guided from the suction means to the vent hole of the belt from falling between the edges on both sides of the belt body and the bottom face material, so that the output of the suction means does not need to be unnecessarily increased. have. In addition, the bag holding apparatus can achieve the same effect as the airtight structure of the timing belt and the suction conveyor.

The timing belt, the airtight structure of the suction conveyor, and the bag holding apparatus which concern on embodiment of this invention are demonstrated based on drawing.

Example  One

As shown in FIG. 1, the vent belt 7 penetrates into the position which divides between the edge parts 5 of the both sides of the width direction of the belt 3 in the timing belt 1, The plurality of teeth 9 arranged at equal pitches in the longitudinal direction are provided on the lower surface of the belt body 3. All the teeth 9 are arrange | positioned inward of the width direction rather than the edge part 5 of the both sides of the strip | belt body 3. As shown in FIG. The edge portion 5 of the belt body 3 has its lower surface as a smooth sliding surface. As the band body 3, it is preferable to apply what passed the core wire which bears the tension | tensile_strength to the protropene rubber excellent in flexibility.

Example  2

As shown in FIG. 2, FIG. 3, the airtight structure 11 of the suction conveyor consists of the bottom face material 15 in which the timing belt 1 and the air path 13 which guides negative pressure to the ventilation hole 7 are formed, The lower surface of the edge part 5 of the both sides of the strip | belt body 3 is provided with two sets of airtight liners 17 which each make sliding contact. The bottom face material 15 receives in the bottom face of the guide groove 19 which extends the tooth 9 of the timing belt 1 in the longitudinal direction. The width of the guide groove 19 is set slightly wider than the overall width of the belt body 3, and the depth of the guide groove 19 is approximately equal to the height of the belt body 3 plus this length of the teeth 9. The same is set. The air passage 13 is an elongated hole or a groove-shaped portion that is open to the bottom surface of the guide groove 19, and is connected to the suction means through the duct 23. Here, the suction means may be one that sucks air like suction ports such as an air blower.

When the above suction means starts, the air escapes from the air vents 7 between the neighboring teeth 9 and flows into the air path 13. For example, when the timing belt 1 is wound around the timing pulley and the timing belt 1 is driven in accordance with the rotation of the timing pulley, the lower surfaces of the edges 5 on both sides of the belt body 3 are respectively 2. Sliding contact with the airtight liner 17 of the bath. Thereby, it can suppress that air | atmosphere escapes between the edge part 5 of the strip | belt body 3, and the inner side surface of the guide groove 19. As shown in FIG. In other words, since the negative pressure guided from the air passage 13 to the vent hole 7 can be suppressed from being discharged between the edge portions 5 on both sides of the belt body 3 and the bottom face material 15, the belt body 3 A suction force capable of satisfactorily sucking the article placed on the back face can be generated in the vent hole 7.

Moreover, when the atmosphere flows into the air passage 13 from the vent hole 7, the inner region of the belt body 3 and the bottom of the guide groove 19 has a lower air pressure than the atmospheric pressure. Based on the pressure difference between these regions and the atmosphere, the edge portions 5 on both sides of the belt body 3 are pressed into two sets of airtight liners 17 by the force in the direction of the arrow P, respectively. Thereby, the edge part 5 of the strip | belt 3 is close to the airtight liner 17, and further suppresses that a negative pressure falls out between the edge part 5 of both sides of the strip | bristle body 3, and the bottom face material 15. FIG. Since it can do this, the said suction force can be increased.

In addition, the air path 13 of the bottom face material 15 may set the arrangement | positioning and shape in the inside of the two sets of airtight liners 17 freely. In addition, the teeth 9 also serve to reinforce the inner portion of the edge portion 5 of the belt body 3, so that the width of the air passage 13 is 1/2 to 3/4 of the tooth width of the teeth 9. Even if it is set to the width | variety to reach, the timing belt 1 does not bend easily in the width direction by the load of the article mounted on the strip | belt body 3. For this reason, the airtight structure 11 of the suction conveyor is advantageous in increasing the said suction force by making the diameter of the ventilation hole 7 and the width | variety of the air path 13 wide, respectively.

The timing belt of the entry type is compared with the timing belt 1 described above. FIG. 4 shows an example in which the timing belt 25 is inserted into the guide groove 19 where the teeth width of the teeth 9 is approximately equal to the overall width of the belt body 3. When the suction means connected to the air path 13 is activated, air flows into the air path 13 from the vent hole 7, but at the same time, the edge portions 5 and the guide grooves 19 on both sides of the belt body 3 are operated. Since the air escapes through the gap with the inner surface of the substrate, the suction force of the vent hole 7 decreases by that amount. Further, as the output of the suction means is increased so that the suction force of the vent hole 7 becomes the desired strength, the amount of the atmosphere passing through the gap between the edge portion 5 and the inner surface of the guide groove 19 also increases, It is unavoidable that the efficiency of the suction means is lowered.

Example  3

As shown in FIG. 5, the airtight structure 26 of the suction conveyor includes a timing belt 1, two bottom airtight members made of flat aluminum, and two sets of airtight liners provided on an upper surface of the bottom material 15. (17) and two sets of sliding materials 27 provided in these airtight liners 17, respectively.

The same name is used for the element already described in Example 2 below, and the description is abbreviate | omitted. The sliding member 27 supports the article in a slidable manner when the article having a size larger than the entire width of the belt body 3 is placed on the timing belt 1. The material of the airtight liner 17 and the sliding material 27 is stainless steel. The overall width of the strip 3 is 50 mm, and the diameter of the vent hole 7 is 8 mm. The pitch of the plurality of vent holes 7 is 35 mm. The thickness of the airtight liner 17 is approximately equal to this thickness of the teeth 9, and the height from the bottom face material 15 to the top surface of the sliding material 27 is 2.2 mm. This is approximately equal to the overall thickness of the timing belt 1.

Example  4

As shown in FIG. 6, the airtight structure 29 of the suction conveyor forms two sets of convex parts 31 in the flat bottom face material 15, and guide grooves 19 between these convex parts 31. ), And the concave member 33 made of ultra high molecular polyethylene is disposed on the bottom surface of the guide groove 19. The concave member 33 includes a bottom plate portion 37 which receives the teeth 9 of the timing belt 1 so as to be in close contact with the bottom surface of the guide groove 19 so as to be slidable, and two sets of airtight liners 17. ) Is integrated. Since the bottom plate part 37 of the concave member 33 has a small coefficient of friction with respect to the teeth 9, the timing belt 1 is compared with directly supporting the teeth 9 with the bottom material 15. The resistance at the time of running can be reduced. Reference numeral 35 designates a ventilation path formed at a position that coincides with the air path 13 of the bottom plate portion 37.

The overall width of the belt body 3 means the belt width [w] of the timing belt 1, and when the tooth width of the teeth 9 is [s], the width [σ] of one edge portion 5 is [sigma] = (ws) / 2, and preferably set in the range of 5 mm ≤ Alternatively, if the thickness of the strip 3 is [t], [σ] may be set in a range of 3t ≦ σ ≦ 15t.

In addition, this invention can be implemented also in the form which added various improvement, correction, or modification on the basis of the knowledge of a person skilled in the art in the range which does not deviate from the meaning. Although the position through which the ventilation hole 7 penetrates the band body 3 coincides between the adjacent teeth 9 (valley), the ventilation hole 7 may penetrate the tooth 9 is shown. The bottom face material 15 and the airtight liner 17 may be integrated. The strip 3 may be an endless shape. In addition, the shape, arrangement | positioning, number, or dimension of the ventilation hole 7 are matters which can be changed suitably.

Example  5

The bag holding apparatus provided with the timing belt 1 is demonstrated. FIG. 7 shows an article at a position facing the film supply means 201, the umbilical device 203, the suction conveyor 207 for conveying the encapsulation 205, and the opening 209 of the encapsulation 205. The outline of the bag holding apparatus 200 provided with the article supply means 213 which supplies the 211, and the insertion apparatus 215 is shown. FIG. 8 shows the shape of the opening 209 of the encapsulation body 205 immediately before the article 211 is inserted by the operation described later by the insertion apparatus 215.

As shown in FIG. 7, the film supply means 201 makes the film 217 wound by roll shape into the shape which folded and overlapped in the middle of the width direction in the direction of arrow T, and is sent out. The umbilical cord device 203 forms the rectangular encapsulation body 205 by heating the two overlapping films 217 with the heat cutter 219, and melting these films with the heat of the heat cutter 219. It is. The said melted part 221 becomes a side edge part of the sealing body 205 by which the film 217 folded in two was fused together.

The suction conveyor 207 conveys the sealing body 205 accommodated in the timing belt 1 by running the several timing belt 1 supported by the bottom face material 15 mentioned above in the direction of the arrow T. will be. A negative pressure is introduced into the vent hole 7 of the timing belt 1 from the suction means so that the sealing member 205 is attracted to the belt body 3 of the timing belt 1. In addition, as described in the second embodiment, the edge portion 5 of the belt body 3 comes into close contact with the airtight liner 17, so that the edges 5 of both sides of the belt body 3 and the bottom face material 15 are separated. Since a negative pressure can be suppressed from the inside, there exists an advantage that it does not need to unnecessarily increase the output of the suction means for guiding negative pressure to the ventilation hole 7.

Next, the structure of the insertion apparatus 215 is demonstrated. Since a well-known technique can be applied to the drive source or guide means described below, each detailed description is omitted. For example, as a driving source, an air cylinder, a hydraulic cylinder, a servomotor, a rotor with a reduction gear, or an electric cylinder for stretching the working rod in accordance with the operation of the rotor may be used. As the guide means, a sliding treatment formed by slidably coupling the slider to the guide rail may be applied.

As shown in Figs. 9 and 10, the insertion apparatus 215 is capable of lifting up and down by the linear operation means 229 for reciprocating the slider 227 in the horizontal direction and the guide means 231 to the slider 227. A door-shaped driven holder 241 to which the standing portion 233 is connected, a support 243 for supporting the article 211 at the same height as the encapsulation 205, and a straight rail extending in the horizontal direction 245 and the cam rail 247 arrange | positioned above the straight rail 245 are provided.

The linear operation means 229 connects the ball nut 251 screwed to the feed screw 249 to the slider 227, and rotates the feed screw 249 to the drive source, thereby moving the slider 227 to the feed screw ( 249). Both ends of the feed screw 249 are rotatably supported by the case of the insertion device 215. The pusher 235 is provided on the frame 237 with an approximately L-shaped insertion protrusion 253 and a transfer protrusion 255 spaced apart from each other in the direction in which the pusher 235 reciprocates. Arrows F and R indicate the direction in which the pusher 235 moves forward or backward with respect to the sealing body 205 together with the slider 227.

The standing part 233 of the driven holder 241 attaches the driven roller 257 which can roll and contact the straight rail 245 or the cam rail 247 inside. In addition, the driven holder 241 fixes the frame 237 of the pusher 235 to the standing portion 239. The support body 243 is a pair of guide rails 259 made of mountain-shaped lightweight steel. The guide rail 259 supports the article 211 by its flange 261. The flange 263 of the guide rail 259 restricts the article 211 from deviating from the inside of the pair of guide rails 259. A smooth bottom plate may be provided between the pair of guide rails 259.

The article supply means 213 is shown in FIG. 10 as the endless belt 267 is wound around the rotary ring 265, but the article 211 is moved from the direction of arrow F to the inside of the pair of guide rails 259. If it can introduce | transduce, it is not limited to the form of the same drawing. In addition, a plurality of rollers 269 are disposed inside the pair of guide rails 259. This is so that the article 211 mounted on the endless belt 267 running to a drive source can slide with the inertia force immediately after detaching from the endless belt 267. Reference numerals 271 and 273 denote the introduction portion and the delivery portion of the guide rail 259, respectively.

The supporting plate 275 shown in FIG. 10 supports the straight rail 245 and the pin 277 disposed above the straight rail 245 and is fixed to the case of the insertion apparatus 215. As shown in FIG. 9, the cam rail 247 extends the inclined portion 281 extending one end 279 in the direction of the arrow F, and the other end 283 extending in the direction of the arrow R. As shown in FIG. It has the horizontal part 285, and the one end 279 is supported by the pin 277 so that rotation is possible in the posture accommodated by the straight rail 245. As shown in FIG. The inclined portion 281 may be a shape that rises and inclines in the direction of the arrow R. Reference numeral 287 in FIG. 9 denotes an insertion through hole for inserting the pin 277 into the cam rail 247.

The operation of the insertion device 215 will be described below. The umbilical apparatus 203 shown in FIG. 7 shape | molds several sealing body 205 one by one, and this sealing body 205 is conveyed by the sealing body conveying means 207. FIG. And when the opening part 209 of one sealing body 205 reaches the front surface of the insertion protrusion 253 of the pusher 235, the sealing body conveying means 207 will stop conveyance of the sealing body 205. FIG. In this state, the linear operation means 229 of the insertion device 215 reciprocates the slider 227, thereby executing the first to fourth steps of the operation described below.

In the first process, in the process of advancing the slider 227, the driven roller 257 moves along the straight rail 245 in the direction of the arrow F from the position shown by the imaginary line 257 'in FIG. 11A shows that the article 211 supplied from the article supply means 213 hits the feed projection 255 of the pusher 235 and stops while the present step is being executed.

In addition, the driven roller 257 moves in the direction of arrow F, and contacts the inclined part 281 of the cam rail 247 from the lower side. Since the inclined portion 281 is pushed up by the driven roller 257, the cam rail 247 pivots the pin 277 in the direction of raising the one end 279 to the point. After the follower roller 257 passes through the clearance between the one end 279 of the inclined part 281 and the straight rail 245 which open | releases by this, the cam rail 247 carries out one end 279 by self-weight. It turns in the downward direction, and one end 279 is received by the straight rail 245 again. When the slider 227 reaches the advance limit, the feed projection 255 of the pusher 235 reaches the position indicated by the solid line in Fig. 11B. At the same time, the insertion protrusion 253 of the pusher 235 reaches the position shown by the solid line in Fig. 12A.

As described above, in the process in which the driven roller 257 moves along the straight rail 245, the height of the driven holder 241 is positioned by the straight rail 245. For this reason, the height of each of the insertion protrusion 253 of the pusher 235 and the transfer protrusion 255 is matched with the article 211 supported by the support body 243. As the slider 227 advances, the article 211 is pushed into the encapsulation 205 by the insertion protrusion 253, leading to the entirety of the article 211 being inserted into the encapsulation 5. Here, "matching" means that the leading ends of the insertion protrusion 253 and the transfer protrusion 255 are slightly below the article 211.

In the second step, the driven roller 257 moves along the straight rail 245 in the direction of the arrow R while the slider 227 retreats, so that one end of the inclined portion 281 of the cam rail 247 ( 279). On the other hand, the insertion protrusion 253 of the pusher 235 is separated from the article 211 inserted into the sealing body 205 in the first step, and retreats from the sealing body 205.

In the third process, the slider 227 retreats further, and the driven roller 257 rides on the inclined portion 281. At this point, the load of the driven roller 257 is applied downward to the cam rail 247, so that the cam rail 247 maintains the posture that the one end 279 is received by the straight rail 245. The driven roller 257 moving in the direction of the arrow R ascends along the inclined portion 281 of the cam rail 247 and then moves along the horizontal portion 285. Thereby, since the driven holder 241 raises together with the driven roller 257, since it moves horizontally, the conveyance protrusion 255 of the pusher 235 is shown by the virtual line 255 'in FIG.11 (b). As it passes above the article 211.

In a 4th process, the driven roller 257 separates from the other end 283 of the horizontal part 285 of the cam rail 247, and returns to the position shown by the virtual line 257 'in FIG. At this point, the transfer projection 255 of the pusher 235 retreats more than the article 211 and reaches the position indicated by the virtual line 255 "in Fig. 11B. In addition, the driven roller 257 ) Moves away from the other end 283 of the horizontal portion 285 to the height accepted by the straight rail 245, so that the pusher 235 also falls along with the driven holder 241.

Subsequently, the conveying means 207 resumes conveyance of the encapsulation body 205 so that the opening 209 of the encapsulation body 205 following the encapsulation body 205 into which the article 211 has already been inserted is pusher 235. When the front end of the insertion projection 253 of the is reached, the sealing body conveying means 207 stops the conveyance of the sealing body 205. The insertion apparatus 215 performs a 2nd 1st process. In the meantime, a new article 211 is supplied from the article supply means 13 to the position shown in Fig. 11A.

On the other hand, the conveyance projection 255 of the pusher 235 which advances from the position shown by the virtual line 255 "in FIG.11 (b) hangs the article 211 supplied between the 1st 1st processes, This article 211 is advanced.The 2nd 2nd process-the 4th process are performed, and the conveyance protrusion 255 of the pusher 235 is upward of the article 211 supplied between 2nd 1st processes. The insertion protrusion 253 of the pusher 235 simultaneously passes upward of the article 211 supplied between the first first steps, as shown by the virtual line 253 ′ in FIG. 12A. It passes through and reaches the position shown by the virtual line 253 ".

Thereafter, the first to fourth steps are further repeated, so that the article 211 supplied between the first first steps is inserted into the insertion protrusion 253 of the pusher 235 as shown in FIG. 12 (b). It is pushed out from between a pair of guide rails 259, and is inserted in the opening part 209 of the sealing body 205 shown in FIG. In addition, since the conveying means 207 repeats the conveyance and stopping of the encapsulation 205 every time the article 211 is inserted into one encapsulation 205, the insertion device 215 supplies the article supply means 213. ), The plurality of articles 211 supplied in turn can be inserted into the plurality of sealing bodies 205 conveyed by the suction conveyor 207, respectively.

The insertion device 215 is preferably provided with a pair of movable guides 301 between the pair of guide rails 259 and the openings 209. The pair of movable guides 301 make each protruding end 303 into a wedge shape, and also makes the cross section into the groove shape of mutually inward direction. The insertion device 215 further includes guide means for guiding the pair of movable guides 301 so as to be movable in the directions of arrows F and R, and driving means for advancing and moving the pair of movable guides 301 in this direction. It is preferable to have.

The pair of movable guides 301 are advanced to advance each of the protruding ends 303 into the openings 209 just before the N-type is pushed out from between the pair of guide rails 259. As a result, the opening 209 is opened larger than the size of the article 211, so that a defect such as the article 211 inserted into the encapsulation 205 from being caught by the opening 209 can be prevented in advance.

In addition, the suction pad 307 is provided at the lower end of the pipe 305 suspended and supported above the timing belt 1, and the suction pad 307 is guided through the pipe 305 from the suction means by the suction pressure. Immediately before the pair of movable guides 301 moves forward, the location of the sealing member 205 may be sucked so that the opening portion 209 opens above the timing belt 1. In addition, when the pair of movable guides 301 retreat from the encapsulation body 205, the protruding ends 303 enter the openings 209 by inclining in the direction in which the protruding ends 303 approach each other. In this case, the movable guide 301 may be operated so as to open the interval of each projecting end 303. Thereby, tension is produced | generated in the opening part 209 of the sealing body 205, and the looseness of the opening part 209 can be prevented.

In addition, this invention can be implemented also in the form which added various improvement, correction, or modification on the basis of the knowledge of a person skilled in the art in the range which does not deviate from the meaning. The film supply means 201 and the umbilical apparatus 203 shown in FIG. 7 may be abbreviate | omitted, and the article 211 may be inserted into the ready-made sealing body. In this case, you may supply a ready-made sealing body on the timing belt 1 of the suction conveyor 207 directly. In addition, the feed screw 249 and the ball nut 251 may be abbreviate | omitted, and the drive source which joined the slider 227 to the piston rod as the linear operation means 229 may be applied.

The speed at which the suction conveyor 207 conveys the encapsulation body 205 is doubled, so that two or more inserting devices 215 arranged in the direction of the arrow F simultaneously deliver the article to the two or more encapsulation bodies 205. You may insert (211). Further, the suction conveyor 207 has already provided a closing device for sealing the opening 209 of the encapsulation 205 after the insertion device 215 inserts the article 211 into the encapsulation 205. You may provide in the middle of the process of conveying the sealing body 205 in which the article 211 was inserted.
