  As shown in FIGS. 3 and 4, the disk supply means 22 includes a first rotating disk 40 that is rotatably disposed so as to partially overlap the article placement surface 36 a of the supply conveyor 20. The rotating disk 40 is set to rotate in a direction substantially along the article conveying direction by the supply conveyor 20 at the overlapping portion at a speed corresponding to the traveling speed of the supply attach 24 by a driving means (not shown). At the peripheral edge of the first rotating disk 40, a plurality of holes 40a that are formed in a shape corresponding to the shape and size of the article 14 and open to the outer peripheral side are arranged at regular intervals (every predetermined interval) in the circumferential direction. Will be opened. In addition, a frustoconical second rotating disk 42 that is coaxial with the first rotating disk 40 and rotates in the opposite direction or in the same direction is disposed inside the position where the hole 40a is formed in the first rotating disk 40. The multiple articles 14 put into the disk supply means 22 are configured to be distributed and accommodated one by one in each hole 40a by the rotating action of both rotating disks 40 and 42. The disk supply means 22 is provided with a plurality of rotating brushes 44 that exclude the articles 14 that are not accommodated in the holes 40a and are placed on the peripheral edge from the peripheral edge.

  A support bed 46 that supports the bottom of the article 14 accommodated in the hole 40a is disposed on the lower surface of the disk supply means 22 corresponding to the hole 40a. The support bed 46 is set at a position slightly higher than the article placement surface 36a of the transfer bed 36, and a portion corresponding to the overlapping portion with the supply conveyor 20 is notched as shown in FIG. Yes. A thin plate-shaped transfer member 48 is disposed from the edge of the cutout portion of the support bed 46 facing the rear side in the rotation direction of the first rotating disk 40 to the article placement surface 36a of the supply conveyor 20. The article 14 is smoothly transferred from the support bed 46 to the transfer bed 36.

  An outer peripheral guide 50 is disposed along the outer periphery of the first rotating disk 40, and a predetermined length range corresponding to the delivery position of the supply conveyor 20 is provided on the peripheral surface of the outer peripheral guide 50 as shown in FIG. An opening 50a is formed over the entire area. Further, below the hole 40a in the first rotating disk 40 corresponding to the delivery position, the article 14 accommodated in the hole 40a is placed in the hole 40a on the front side in the disk rotation direction from the transfer member 48. A guide 52 for guiding the vehicle from the outside to the outside is provided. That is, the article 14 accommodated in the hole 40a is discharged from the hole 40a by the guide guide 52 along with the rotation of the first rotating disk 40, and is supplied from the supply conveyor 20 through the opening 50a of the outer peripheral guide 50. It is configured to be supplied between the attachments 24 and 24. The article 14 discharged by the guide guide 52 is supplied with zero drop between the supply attachments 24 and 24 of the supply conveyor 20 in a state of being placed on the article placement surface 36a of the supply conveyor 20, and the delivery position. It is comprised so that the attitude | position change of the article | item 14 may be prevented.

  An inner peripheral guide having an arc shape along the circular arc of the outer peripheral guide 50 on the inner peripheral side from the formation position of the hole 40a over a required range corresponding to the delivery position of the supply conveyor 20 in the first rotating disk 40. 54 is provided so that a large number of articles 14 put into the disk supply means 22 do not flow out from the opening 50a to the supply conveyor side.

  Above the travel path of the supply attachment 24 at the delivery position, a compressed air blowing means 56 connected to a compressed air supply source and capable of blowing compressed air downward is provided (see FIG. 4). In other words, the compressed air blown from the compressed air blowing means 56 is configured to press the article 14 against the article placement surfaces 36 a and 36 a serving as the feed placement surface of the supply attachment 24.

  The article push surface 24a facing the article 14 projecting upward from the article placement surfaces 36a, 36a of the transfer beds 36, 36 in the supply attach 24 has a concave portion having an arc shape that curves inward from the open side. 58 is formed. As shown in FIG. 6, the recess 58 is connected to a first arc portion 58a composed of an arc portion whose arc length is set to be smaller than a quarter circle at the upper end portion thereof and to be continuous below the first arc portion 58a. The second arc portion 58b is set to have a larger radius of curvature R2 than the first arc portion 58a, and the concave portion 58 is configured to have a substantially quarter arc shape as a whole. That is, the upper end portion of the first arc portion 58a is connected to the upper open base end portion formed on the flat surface 24b in the recess 58, and is curved inward from the open side toward the lower side, and the flat surface 24b. The upper end portion of the second arc portion 58b is connected to the lower end portion of the first arc portion 58a facing inward, and curves downward toward the open side, and the lower end portion is flat in the recess 58. The lower open base end formed on the surface 24b is connected.

Further, the arc shape of the first arc portion 58a has a maximum turning radius R from the contact point P when the article 14 pushed by the supply attach 24 rolls forward on the article placement surface 36a from the conveying posture, In other words, in the oval article 14 of the embodiment, the pushing surface of the article 14 is smaller than the turning radius from the article placing surface 36a at the tip of the rear arc located in the major axis direction of the ellipse, and the pushed surface of the article 14 is in the recess 58. For example, as in the embodiment shown in FIG. 6, in the article 14 having an arc shape, the radius of curvature R1 is set to be larger than the arc r of the surface to be pushed. and the upper end portion of the first arc portion 58a of the recess 58, the article 14 is set so as to face from the rotation locus of the maximum rotation radius R from the grounding point P at the time of pre-rolling downwards. Thereby, when the article 14 rolls forward, the pushed surface of the article 14 can come into contact with the first arc portion 58a. Furthermore, the protrusion amount L from the article placement surface 36a in the supply attach 24 is set from half the article height to substantially the same height. At this time, the lower end portion of the second circular arc portion 58b is positioned below the article placement surface 36a of the supply conveyor 20, and the lower end portion is configured not to contact the article 14. Here, when a plurality of types of articles 14 having different heights are packaged by the horizontal bag making and filling machine 12, the size difference from large to small is limited for granular articles such as candy and caramel. Therefore, in the supply conveyor 20, the protrusion amount L of the supply attachment 24 from the article placement surface 36a can be set by setting it corresponding to the article 14 having the maximum height dimension.

(Effects of Example)
Next, the operation of the article supply device of the horizontal bag making and filling machine according to the embodiment will be described. When a large number of articles 14 are supplied to the disk supply means 22, the articles 14 are rotated by the first and second rotating disks 40, 42 that rotate relative to each other, so that each hole portion of the first rotating disk 40 is rotated. 40a is distributed and accommodated one by one. The article 14 accommodated in the hole 40a moves with its bottom supported by the support bed 46, and then on the article placement surface 36a of the supply conveyor 20 via the thin plate-like transfer member 48. Delivered smoothly.

  When the hole 40a in which the article 14 is accommodated arrives at the position where the guide guide 52 is disposed, the article 14 accommodated in the hole 40a is directed outward from the hole 40a by the guide guide 52. Extruded and supplied between the supply attachments 24, 24 of the supply conveyor 20 through the opening 50 a of the outer peripheral guide 50. Since the bottom of the article 14 discharged from the hole 40a is supported by the article placement surface 36a of the supply conveyor 20, the delivery of the article 14 from the disk supply means 22 to the supply attach 24 is in a state of no drop. At this time, the article 14 does not bounce due to the delivery drop, and the posture change is suppressed. Further, the article 14 is pressed against the article placement surfaces 36a, 36a by the compressed air blown from the compressed air blowing means 56 at the delivery position of the article 14 from the disk supply means 22 to the supply attachment 24. It is possible to correct the posture of the article 14 whose posture has been changed before it is transferred by the supply attachment 24, and it is possible to prevent the posture change caused by the dance of the article due to the collision with the article 14 during the transfer of the supply attachment 24. .

  Then, the article 14 transferred to the supply conveyor 20 is pushed by the supply attach 24 toward the downstream bag-making device 18 on the article placement surfaces 36a and 36a. At this time, since the article guides 26 and 26 extend to the article passage opening of the bag making device 18 on both sides in the width direction of the article 14, the article 14 is moved from three sides by the supply attach 24 and the article guides 26 and 26. Even when the article 14 held and pushed by the supply attach 24 changes its posture, it is prevented from moving out of the article conveyance path. Further, by setting the protrusion amount L of the protruding portion of the supply attach 24 from half of the article height to substantially the same height, the article 14 jumps over the supply attach 24 and moves rearward when the article is fed. Is prevented. Further, even when the bag making height of the tubular film obtained by the bag making machine 18 is set to the minimum size according to the article height, the upper end of the supply attach 24 hits the upper wall of the tubular film to make the bag. There will be no defects.

  Here, in the case where the article 14 has an arcuate shape such as an ellipse, such as a candy, the article placed on the article placement surfaces 36a, 36a of the supply conveyor 20 When the feed 14 is pushed at high speed by the supply attach 24, the article 14 is transported so that the rear side (supply attach side) is lifted by the frictional resistance between the bottom and the article placement surfaces 36a and 36a. Try to move forward.

  However, in the embodiment, since the arc shape of the first arc portion 58a and the formation position of the first arc portion 58a in the supply attach 24 are set as described above, the article 14 is placed on the article placement surface 36a, when the article is pushed by the supply attach 24. Even when rolling so that the rear side is lifted by the frictional resistance with 36a, as shown in FIG. 6, the article 14 is placed on the article placement surface by the first arc part 58a formed so as to cover the rear upper part of the article 14. It acts to be pressed against 36a, 36a, and excessive forward rotation of the article 14 is prevented. That is, even when high-speed packaging is performed at a packaging speed of, for example, about 650 bags / min or more to about 1500 bags / min, conveyance failure due to a change in the posture of the article 14 during conveyance on the supply conveyor 20 can be prevented. The article 14 can be satisfactorily supplied to the tubular film 16a formed into a tubular shape by the bag making device 18 to prevent the occurrence of defective packaging. Further, the lower end portion of the second arc portion 58b constituting the concave portion 58 in the supply attach 24 is set to be positioned below the article placement surface 36a of the supply conveyor 20, and therefore the supply attach 24 At the start of pushing by or during conveyance of the supply conveyor 20, it is possible to prevent the rotation of the article 14 from being kicked at the portion formed below the lower end portion.

  In addition, since the concave portion 58 in the supply attach 24 of the embodiment is almost arc-shaped and does not have a stepped portion, the outer peripheral portion of the article 14 is not caught by the corner portion and blown off. . Further, the curvature radius R2 of the lower second arc portion 58b is set larger than the curvature radius R1 of the upper first arc portion 58a in the concave portion 58, so that the article 14 supplied from the disk supply means 22 can be obtained. When the front part in the conveying direction is inclined upward, the pushed surface of the article 14 moves upward along the second arc part 58b having a large curvature radius when pushed by the supply attachment 24. Since the forward rotation is started, the initial speed at the time of rotation can be reduced, and the rotation inertia when the article 14 is rotated can be made smaller than that when the same arc is used. Thereby, rotation of the article | item 14 can be suppressed more reliably by the 1st circular arc part 58a.

  In other words, even if the shape of the article 14 is easy to roll when being fed by the supply attach 24, the bag making machine 18 is used when delivering the article from the disk supply means 22 to the supply conveyor 20 when packaging at high speed or by the supply conveyor 20. When the article is conveyed toward the vehicle, it is possible to prevent a situation in which the article 14 rotates excessively or jumps out of the article conveyance path due to the pivoted moment. Accordingly, the posture of the article 14 during transportation is not disturbed, and the generation of defective packaging due to poor transportation can be remarkably reduced.

  Here, when the article 14 is a small-sized product such as a candy, the range of large to small sizes is limited even if the individual shape sizes are different. The shape of the first arc portion 58a in the supply attach 24 is set to a shape having a radius of curvature that can be adapted to each shape of the article 14, and the protrusion amount L of the supply attach 24 from the article placement surface 36a in the supply conveyor 20 is set. Can be accommodated by adjusting to a value that can be adapted to any article 14 within the range described above. In other words, it is possible to transport a plurality of types of articles 14 satisfactorily without changing the posture without changing the supply attachment 24 according to the shape size of the article 14.

[Example of change]
The present application is not limited to the configuration of the above-described embodiment, and other configurations can be appropriately employed.
1. The compressed air blowing means 56 may be any one that is employed according to the properties of the article 14 such that the attitude of the article 14 is likely to change when the article 14 is delivered from the disk supply means 22 to the supply conveyor 20. .
2. The disk supply means 22 discharges the article 14 from the outside of the hole 40a with no drop, but a method of discharging below the hole 40a as in the conventional example may be adopted.
3. In the embodiment, the case where the second arc portion 58b having a large curvature radius is connected to the recess 58 of the supply attach 24 below the first arc portion 58a has been described. However, the downward direction is directed downward to the first arc portion 58a. Thus, it is possible to adopt a configuration in which straight portions extending in a slanted shape toward the front or the front are continuously connected.
