In addition, the two rotation means 12 supported by the individual back square bars 84 are mutually paired. This will be described later.

As shown in FIG. 4, 8, the advancing means 7 is equipped with the conveying means which screwed the ball nut 74 to the conveying screw 73 supported by the support body 72. As shown in FIG. The support body 72 is fixed to two hangers 93 spaced apart in the advancing direction. The ball nut 74 is attached with a drooping member 75 extending downwardly to the ball nut 74 and a drooping member to a coupling member 77 for joining two retreating members 76. (75) is connected. The advancing and receiving member 76 is guided in the advancing direction by guide means for engaging the type 78 fixed to the upper surface thereof with the slide rail 79. The transverse member 71 connects the slide rail 79 and the hanger 93.

Moreover, the pusher 10 which consists of steel plates is attached to each advancing / removing member 76 with the displacement means 14 interposed. A servo motor, not shown in the figure, is connected to the feed screw 73, and when the feed screw 73 is rotated by the servo motor, two retracting members 76 and two displacement means 14 and Together, the pusher 10 moves forward. When the feed screw 73 rotates in the opposite direction, the pusher 10 retreats. In addition, the advancing means 7 can freely increase or decrease the range in which the advancing means 7 advances or pushes the pusher 10 by controlling the servomotor described above.

As shown in Figs. 4 and 8, the displacement means 14 attaches the air cylinder 141 to the individual retracting members 76, and supports the bracket 142 by supporting the operation of the piston rod. It is turning around (143). As the bracket 142 rotates, the plurality of hooks 16 formed on the edge portion of the pusher 10 move up and down. In the state where the displacement means 14 lowers the hook 16 of the pusher 10, the hook 16 is slightly smaller than the contents 4 moved by the moving means 6, as shown in FIG. Lowers. The pusher 10 is fastened to the bracket 142 with a bolt or the like, and when the bolt or the like is loosened, the pusher 10 can move freely in the conveying direction. In addition, the reciprocating inserting apparatus 1 is provided with two retreating means 7, and each retreating means 7 retreats two displacement means 14 together with two retreating members 76, respectively. . For this reason, the reciprocating insertion apparatus 1 can advance or elevate four pushers 10 simultaneously.

The fixing member 121 is fastened to the rear square bar 84 with a bolt or the like, and when the bolt is loosened, the fixing member 121 can freely move in the conveying direction. The rotating member 123 can rotate around the vertical axis with the hinge 122 as a supporting point. The rear part 124 of the rotation member 123 is exerted with the return spring 125 which consists of a tension coil spring. This is for turning the two pivoting members 123 in the direction in which the tip 15 of each of the two guide horns 11 facing each other approaches.

Moreover, the air cylinder 126 is attached to the fixing member 121 with the attachment piece 127 interposed, and the stopper 128 is provided in the position which opposes the attachment piece 127. When air pressure is supplied to the air cylinder 126, the rotation member 123 is pushed by the piston rod 129 and rotates until it hits the stopper 128. As a result, as shown in FIG. 9B, the two guide horns 11 rotate in a direction away from each tip 15. When the air pressure is cut off from the air cylinder 126, the two guide horns 11 return to the attitude shown in the same drawing (a). The combination of the guide horns 11 for realizing such an operation is called a 'pair'.

The guide horn 11 forms a groove-shaped side piece 19 on a substantially triangular bottom piece 18 in which the tip 15 is sharpened and the rear edge 17 is inclined downward. The leaf spring 20 which extends toward the front-end | tip 15 of the bottom piece 18 is attached to the upper surface. It is preferable that the guide horn 11 arrange | positioned in the upstream of a conveyance direction among the pair of guide horns 11 makes the bottom piece 18 wider than the downstream one.

In addition, the reciprocating insertion apparatus 1 is provided with the suction pad 21 and the proximity means 22 which raises and lowers the suction pad 21, as shown to FIG. The proximity means 22 attaches the support member 221 to the lower surface of the movable support body 91, and supports the air cylinder 223 which directed the piston rod 222 downward with the support member 221. The front square bar 224 is connected to the piston rod 222, and the suction pad 21 is held above the conveying means 5 by the stay 225 to the front square bar 224. The stay 225 is fastened by a bolt etc. to the front square bar 224, and can loosen | move freely in a conveyance direction when a bolt etc. are loosened.

The solenoid valve which is not shown in figure is provided in the path | route where said negative pressure is led. By opening / closing this solenoid valve, a suction force can be generate | occur | produced timely or it can break | break. In addition, the reciprocating insertion device 1 is provided with eight suction pads 21, and can raise and lower the eight suction pads 21 simultaneously according to the operation | movement of two air cylinders 223. As shown in FIG.

The operation of the reciprocating insertion device 1 will be described below. The alphabetic characters preceded by the following sentences are indicative of the operation process. The drawings refer to FIGS. 1 through 4 in addition to indicating among the sentences. The servo motor, air cylinder, or solenoid valve described above operates based on a program recorded in a storage medium that can access a computer controlling these.

First, the some bag 3 is arrange | positioned at equal intervals on the endless belts 51 and 52 of the conveying means 5. For example, the bag 3 sequentially supplied from the bag making apparatus may be placed on the endless belts 51 and 52 of the conveying means 5 in that order. On the other hand, the contents 4 are sent toward the moving means 6 from the feeder provided on the side of the moving means 6. The content 4 which reached | attained the endless belt 62 of the movement means 6 by this maintains the attitude | position opposite to the opening part 2 of the bag 3 mounted on the conveyance means 5, It moves in the conveyance direction by (6).

Moreover, the reciprocating means 9 makes the movable support 91 stand by the limit which can move back. The displacement means 14 raises the pusher 10, and the retreat means 7 retracts the pusher 10. The entrance and exit means 8 retracts the guide horn 11 and the lifting means 13 raises the guide horn 11. This state is shown in Fig. 10A. The two rotating means 12 pivot the pair of guide horns 11 in the direction in which the respective tip 15 approaches.

A: When the four bags 3 and the four contents 4 reach the range defined by the dimension line x of FIG. 1, the reciprocating means 9 advances the movable support 91. Move it. As a result, four pushers 10 and eight guide horns 11 move forward at the conveyance speed. In the following steps, the operations of the four pushers 10 and the eight guide horns 11 simultaneously proceed, but the description thereof will be carried out by paying attention to one bag 3 and one content 4.

B: As shown in Fig. 10 (b), the displacement means 14 lowers the pusher 10. Then, the proximity means 22 lowers the suction pad 21 to a height close to the bag 3, and immediately lifts the suction pad 21. Thereby, since the vicinity of the opening part 2 of the bag 3 is pulled up by the suction pad 21, the bag 3 can spread the opening part 2 to an up-down direction. In this step, the bag 3 is adsorbed by the endless belts 51 and 52 of the conveying means 5.

C: The lifting means 13 lowers the guide horn 11. As the advancing means 7 advances the pusher 10 to the bag 3, the contents 4 are slid from the moving means 6 toward the bag 3. In this process, the timing at which the contents 4 reach the rear edge 17 of the guide horn 11 is calculated, and the access means 8 advances the guide horn 11. As shown in FIG. 11, after the tip 15 of the pair of guide horns 11 enters the opening 2 of the bag 3, the entry and exit means 8 stops. Reference numeral 63 in FIG. 3 denotes a groove portion for preventing the hook 16 of the pusher 10 from being caught by the endless belt 62 in this step.

D: As shown in Fig. 12, the two pivoting means 12 pivot the pair of guide horns 11 in a direction in which the respective tip ends 15 are far from each other. As shown in Fig. 10C, the advancing means 7 further advances the pusher 10. Figs. As a result, the contents 4 are in sliding contact with the bottom pieces 18 of the pair of guide horns 11 entering the openings 2, and guided to the respective side pieces 19 while the openings 2 are provided. Insert inside of. As shown in Fig. 13A, after the entire contents 4 are inserted into the bag 3, the advancing means 7 stops. In this step, the angle at which the pair of guide horns 11 rotate and the timing thereof are matters that can be arbitrarily adjusted.

In the process of D, since the space | interval of the front-end | tip 15 of a pair of guide horn 11 widens, and moderate tension | tensile_strength generate | occur | produces in the opening part 2, since the opening part 2 bends, By restricting the deformation, it is possible to avoid the content 4 from being caught in the opening 2 of the bag 3. In addition, even if the size of the bag 3 is close to the width of the content 4, the content (4) of the bag 3 is such that there is no margin left between the bag 3 and the content 4 inserted therein. ) Can be inserted smoothly. This may prevent breakage of the contents 4. In addition, the bottom piece 18 of the guide horn 11 prevents the contents 4 from rubbing against the inclined plate 61. The side piece 19 prevents the contents 4 from deviating from the opening 2, and the leaf spring 20 prevents the contents 4 passing through the inside of the side pieces 19 from rising from the bottom piece 18. Prevent.

E: As shown to FIG. 13 (b), the displacement means 14 raises the pusher 10. FIG. As shown in the figure (c), the suction force of the suction pad 21 is cut off, and the bag 3 is opened from the suction pad 21. Then, the retreat means 7 retracts the pusher 10, and the access means 8 retreats the guide horn 11. As a result, the pusher 10 and the guide horn 11 are separated from the bag 3. Reference numeral 4 'indicates the contents directed toward the range newly defined by the dimension line x in FIG.

F: The two rotating means 12 rotate the pair of guide horns 11 in the direction in which each tip 15 approaches. The elevating means 13 raises the guide horn 11, and the reciprocating means 9 moves the movable support 91 backward. Thereby, the pusher 10 and the guide horn 11 return to the state shown in FIG. 10 (a). Thereafter, the reciprocating insertion device 1 can repeatedly execute the steps A-F.

In the step F, since the movable support 91 moves backward after the guide horn 11 is raised, the guide horn 11 can be prevented from rubbing against the moving means 6 or the inclined plate 61. . In addition, although the process of said E must be started before the reciprocating means 9 changes the movable support body 91 to move forward, the retraction of the pusher 10 by the advancing means 7 is a reciprocating means 9 ) May be completed when the movable support 91 is moved backward.

As described above, the reciprocating insertion device 1 can continuously perform the step of inserting the contents 4 into the bag 3 while continuing the conveyance of the bag 3. In addition, when the operations of the retreat means 7 and the take-out means 8 are accelerated in the above steps C and D, and the time for inserting the contents 4 into the bag 3 is shortened, the reciprocating means ( 9) can shorten the cycle time for reciprocating the movable support 91. Moreover, according to the reciprocating inserting apparatus 1, since four contents can be inserted into four bags 3 simultaneously, the number of the contents 4 which can be inserted into the bag 3 by a predetermined time is doubled. (倍增) can be.

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. For example, one retracting means 7 may advance and retract four pushers 10 simultaneously, or one entry and exit means 8 may advance and retreat eight guide horns 11 simultaneously. The number of each of the pusher 10 and the guide horn 11 is a matter set in consideration of the conveying speed of the moving means 6, the moving speed of the advancing means 7 and the access means 8, and the like. The guide horn 11 may be a guide member for guiding the contents 4 to the inside of the opening 2 of the bag 3, and the present invention is not characterized by the shape of the guide horn 11.

In addition, the bag 3 and the contents 4 do not need to be rectangular. Although the contents 4 are shown as one sheet of paper, a booklet, a small article, a plurality of sheets stacked on top of each other, or a combination thereof may be inserted into the bag 3 as one contents 4. In this case, in order to prevent the problem that the content 4 inserted into the bag 3 in the process of D is liable to be caught by the upper edge of the opening 2 by increasing the thickness of the content 4, Guidance aids described may be added.

FIG. 14 shows an example in which the upper piece 302 of the hook-shaped stay 301 constituting the guide assistance means 30 is bolted to the front square bar 224. A side view of the guidance aid 30 is shown in FIG. The hook type stay 301 is located in the front square bar 224 so that the lower side 303 may approach the opening 2 of the bag 3 from above. The sliding contact piece 304 is fixed to the lower piece 303 of the hook type stay 301 with a bolt. The sliding contact piece 304 preferably has a moderate elasticity and smooth surface, such as a bag made of a synthetic resin film such as polyethylene terephthalate, a leaf spring, or leather.

The shape of the sliding contact piece 304 is not limited to the C-shape shown, and the sliding contact is made at the time when the vicinity of the opening 2 of the bag 3 is lifted up to the suction pad 21 in the step B. The tip of the piece 304 should just be extended to the position lower than the suction pad 21 in the vicinity of the opening part 2. And, as shown in Fig. 15 (b), in the process of the contents 4 enter the opening 2 as the advancing means 7 advances the pusher 10, the contents 4 are in sliding contact. In contact with the piece 304, the sliding contact piece 304 deforms in a form in which its tip is drawn into the opening 2. For this reason, since the sliding contact piece 304 is interrupted | blocked between the content 4 which passes through the opening part 2, and the upper edge of the opening part 2, the said problem can be prevented previously.

In addition, as shown in the figure, the hook-type stay 301 is attached to the front square bar 224 with a hinge therebetween so that the hook-type stay 301 standing upright can turn in the direction of arrow θ, and the return spring or the like. The hook-type stay 301 may be applied in the direction of arrow θ. And just before the advancing means 7 advances the pusher 10, you may return to the posture which stands up the hook-type stay 301 using an air cylinder, a solenoid, etc. which are not shown in figure. In this case, a C-shaped steel plate may be applied as the sliding contact piece 304. The effects described herein can be achieved regardless of the position of the hinge. The hinge may be provided below the hook-type stay 301 so that the lower piece 303 can pivot in the vertical direction in the drawing.
