It is set as follows. Note that the rotation position and the operation range of the operation arm 58 are set to appropriate values for the rotation amount of the servo motor according to the actual posture change state of the article W.

  A supply conveyor 40 of the horizontal bag making and filling machine is connected in series to the downstream side of the posture changing conveyor 24. The supply conveyor 40 turns the aligned article W, which has been turned to the horizontal posture by the posture changing conveyor 24 and conveyed, into a tubular film f (see FIG. 3) formed by the bag making means 60 arranged on the downstream side. It is configured to supply toward.

  As shown in FIG. 1, the supply conveyor 40 is arranged in parallel spaced apart from each other across the conveyance center of the conveyor, and is continuously run by a drive motor such as a servo motor to place and convey the articles W. The supply belts 42 and 42 are spaced apart from each other so that the side surfaces of the article W can be guided on both the left and right sides of the article conveyance path, and run at the same speed as the supply belts 42 and 42 by a drive motor such as a servo motor. A pair of side belts 44 and 44 are provided. The running speeds of the supply belts 42 and 42 are set lower than the conveying speed of the attitude changing conveyor 24 (the running speed of the lower feed belt 26), and are accepted from the attitude changing conveyor 24 in an aligned state of one or two rows. The article W can be conveyed toward the tubular film f while maintaining the alignment posture.

  The pair of side belts 44 and 44 are configured to be movable toward and away from the conveyance center of the conveyor, and the number of rows of articles W and the number of articles W can be adjusted by an interval adjusting means including an adjusting screw mechanism and its operation handle. The distance between the side belts 44, 44 can be adjusted according to the size of the belt.

  On the downstream side of the supply conveyor 40, the articles W placed in a row across the supply belts 42 in the separated portions of the rows of the supply belts 42, 42 are arranged in a cylinder. A pushing conveyor 46 is arranged to push toward the film f. The push conveyor 46 is driven by a drive motor such as a servo motor, and as shown in FIG. 3, the push member 50 is placed at predetermined intervals on a cord 48 such as a toothed endless belt that runs in the conveying direction.

Thus, the film transfer means is driven and controlled.

(Effects of Example)
Next, the operation of the article supply apparatus for a packaging machine according to the above-described embodiment will be described. In the following description, an example in which six articles W are gathered in two rows with three rows in one row, an example in which three items W are gathered in one row, and a few dozen An example will be described in which (for example, 10) collective articles are gathered and supplied without being lined up. Note that the present invention can be applied to the supply of the aligned articles W having a plurality of articles other than three and a different number of sets for each row. Further, it is assumed that the correcting means 56 is set so that the operating arm 58 is continuously changed to the first posture, the second posture, and the third posture in accordance with the case where the number of sets is three.

[When supplying aligned articles assembled in two rows to the supply conveyor]
As shown in FIG. 1, the articles W accumulated in both the accumulation conveyors 10 and 10 are sent to the alignment conveyors 12 in a vertical posture and sequentially conveyed to the downstream side, from the most downstream alignment conveyor 12 toward the upstream side. Then, articles W are placed one by one on each of the up to third alignment conveyors 12 and stored.

  Article delivery timing (cylindrical film f) to the merging conveyor 16 after the detection means detects that the articles W have been stored in the alignment conveyors 12 and 12 by a predetermined number of rows (three in each row) The third alignment conveyor 12 from the most downstream side to the upstream side is controlled to travel at the same time in accordance with the conveyance position of the article W synchronized with the feed position of the sheet, and the three articles W in each row are controlled. It is sent out toward the junction conveyor 16 at a time. In addition, since the alignment conveyor 12 is composed of an adsorption conveyor, the posture of the article W such as a roll pan and the slip of the article W can be prevented even during high-speed conveyance, and the merging conveyor 16 can be changed every predetermined number. The articles W can be sent out in a state where they are aligned at regular intervals.

  In the process in which the articles W delivered from the alignment conveyors 12 to the merging conveyor 16 are placed on the conveyor belt 18 and conveyed, the side portions of the articles W are guided by the corresponding guide belts 20 so as to be closer to the conveyance center of the conveyor. Moved. In other words, the articles W in each row that are separated from each other on the left and right sides are brought closer to each other toward the transport center of the conveyor. Since the traveling speeds of the conveyor belt 18 and the guide belt 20 are set to be the same, the three articles W in each row are in a vertical orientation along the inclination of the guide belt 20, and the articles W, W before and after the front and rear are arranged. Are conveyed to the downstream side in an aligned state while maintaining the interval.

  The articles W in the respective rows that have been gathered by the merging conveyor 16 are delivered to the lower feed belt 26 in the attitude converting conveyor 24 in a vertical orientation and conveyed. Articles passing through the operating arm 58 with its side portions being brought into contact with each other by changing the tilting position of the operating arm 58 in the order of arrival of the second and third plurality of articles W in order from the first article W in each row. The path toward the downstream side of W is set to be sequentially changed in the width direction of the conveyor. Here, the operation of the operation arm 58 is set to perform different operations as follows depending on the relationship between the traveling speed of the lower feed belt 26 and the traveling speed of the turning belt 28.

(When the traveling speed of the turning belt is slower than the traveling speed of the lower feed belt)
As shown in FIG. 4 (a), the actuating arm 58 is moved from the first position (L1) closer to the conveyance center of the conveyor toward the outer side in accordance with the arrival of the articles W in each row. L3) is set so as to be continuously tilted, and the article W arriving in the first vertical orientation in each row has a side portion that contacts the operating arm 58 tilted to the first position (L1). Passed by being guided, the conveyance path from the upstream side changes toward the conveyance center of the conveyor and is conveyed toward the downstream side. Next, as the second article W arrives to the side of the operating arm 58, the operating arm 58 is continuously tilted so that the downstream end is directed outward from the conveyor transport center. L2), and the path of the second article W whose side is in contact with and guided by the operating arm 58 is changed to a position outside the first article W. As the third article W continues, the operating arm 58 tilts further from the second position (L2) to the third position (L3) toward the outside of the conveyor, and the side of the third article W is moved. Is brought into contact with and guided by the operating arm 58, so that the path is changed to a path further outward than the second article W and conveyed. The article W whose conveyance path is sequentially changed outward by the operating arm 58 reaches the skew portion 28a of the turning belt 28 disposed on the downstream side by the lower feed belt 26. The turning belt 28 is set so as to travel at a lower speed than the lower feed belt 26, and the article W rotated by the turning belt 28 is rotated outward so that the front thereof is brought close to the belt side. (Refer to the second article W in FIG. 4A). At this time, since the regulating member 36 is positioned in front of the leading article W in each row and moves at a lower speed than the traveling speed of the lower feed belt 26, the front side of the leading article W comes into contact with the regulating member 36 and the advancement thereof is performed. Be regulated. As a result, the articles W in each row are sequentially turned to the horizontal posture, and the skewed portion 28a to the straight portion 28b of the turning belt 28 in a state where the posture of the article W after the horizontal orientation is regulated by the regulating member 36. Then, the front and back of each article W are aligned and gathered in two rows of sideways postures in contact with each other and conveyed downstream. By changing the position at which the operating arm 58 contacts and guides the side portion of the article W by controlling the amount of operation of the correction means 56, the path is changed in order in the order of arrival of the article W toward the outside of the conveyor. Thus, the article W reaching the turning belt 28 is set so that the upstream article W is positioned on the outer side in the order of arrival.

(When the traveling speed of the turning belt is faster than the traveling speed of the lower feed belt)
In this example, the operation of the operation arm 58 is set to an operation position opposite to that in the previous embodiment. That is, as shown in FIG. 4 (b), the operating arm 58 moves from the third position (L3) on the outer side of the conveyor toward the conveying center of the conveyor in accordance with the arrival of the articles W in each row. The first to third articles W, which are set so as to continuously tilt toward the position (L1) and arrive in each row in the vertical orientation, have a conveyance path to the downstream side of the conveyor. It is gradually changed toward the conveyance center and reaches the skew portion 28a of the turning belt 28. The turning belt 28 is set so as to run at a higher speed than the lower feed belt 26, and the article W rotated by the turning belt 28 is rotated in a direction in which the front thereof is separated from the belt of the turning belt 28. It turns inward (see the second article W in FIG. 4B). At this time, since the regulating member 36 is positioned in front of the leading article W in each row and moves at a lower speed than the traveling speed of the lower feed belt 26, the front side of the leading article W abuts on the regulating member 36 and its advance is regulated. Is done. Thereafter, similarly to the above, the articles W in each row are sequentially turned to the horizontal posture, aligned and gathered in a state where the horizontal posture is regulated by the regulating member 36, and conveyed downstream. By changing the position at which the operating arm 58 contacts and guides the side portion of the article W by controlling the operation amount of the correction means 56, the course is changed sequentially by changing the position of the article W toward the inside of the conveyor in the order of arrival of the article W. The article W reaching the turning belt 28 is set so that the upstream article W is positioned in the inner position in the order of arrival, and when the article W is turned against the turning belt 28, the succeeding article W is placed behind the preceding article W. The position where the front is in contact can be set to the inner position as the article W on the upstream side.

  In any case where the traveling speed of the turning belt 28 is set to be higher or lower than the traveling speed of the lower feed belt 26, the article W is conveyed from the start end to the end of the lower feed belt 26. In the above, it is more preferable to change the forward speed of the restricting member 36 so as to temporarily pulsate a plurality of times under the condition that the traveling speed of the restricting member 36 is set lower than that of the lower feed belt 26. Thereby, the contact resistance when the articles are in contact with each other and rotating can be relaxed, and the turning operation by the turning belt 28 can be performed more satisfactorily.

  Regarding the speed difference between the lower feed belt 26, the regulating member 36 and the turning belt 28, for example, when the running speed of the regulating member 36 is “1” as the reference speed, the running speed of the lower feed belt 26 with respect to the reference speed. Is “1.5 to 2 times”, and the traveling speed of the turning belt 28 is set to “1.5 to 2 times” when it is higher than the lower feed belt 26, and is set to “0.8 times” when it is low. Is done. The speed difference is not limited to the above, and is set as appropriate according to various conditions such as the size and shape of the article W.

  Then, the restriction member 36 is moved downwardly outside the conveyance path and the restriction is released, so that the two rows of aligned articles W are delivered toward the supply conveyor 40.

  The supply belts 42 and 42 in the supply conveyor 40 place and convey the aligned articles W for each row, and a pair of side belts 44 and 44 guide the left and right sides of each row and are arranged downstream. It is conveyed toward the bag making means 60. In addition, since the conveyance speed in the supply conveyor 40 is set to be lower than the conveyance speed in the attitude conversion conveyor 24, the front and rear abut on the attitude conversion conveyor 24 when the article is transferred from the attitude conversion conveyor 24 to the supply conveyor 40. The aligned articles W are prevented from being separated from each other.

  When the detection means 52 detects that the detection timing of the aligned article W is delayed in relation to the feeding position of the tubular film f during the conveyance of the supply conveyor 40, the conveyance delay of the article W is delayed. Corresponding to the above, the transfer speed of the tubular film f is reduced. As a result, the aligned articles W are fed from the supply conveyor 40 through the crossing conveyor 62 to an appropriate position in the tubular film f formed by the bag making means 60.

  That is, the article W fed to the attitude changing conveyor 24 is rotated by the skew portion 28a of the turning belt 28 to change the attitude from the vertical attitude to the horizontal attitude, and the front of the article W is transferred from the lower feeding belt 26 at that time. Since it is supported by the regulating member 36 that moves forward at a low speed, it can be conveyed while maintaining the aligned state in the posture converted to the horizontal direction, and the posture of the article W is disturbed during the conveyance and the alignment state changes. This can be suppressed, and the manual reworking of the transport posture can be reduced. Further, the apparatus can be downsized and the configuration can be simplified as compared with the conventional apparatus that combines the conveyors so as to be orthogonal to each other, so that the installation space can be saved and the manufacturing cost can be reduced.

  Since the correction means 56 is set so that the course toward the downstream side of the article W passing through the side parts abutted and guided in response to arrival of the plurality of articles W is sequentially changed in the width direction of the conveyor. When the article W is turned by the turning belt 28, the problem that the turning is prevented by contact between the articles and cannot be aligned in a sufficient lateral posture can be avoided.

  Specifically, when the traveling speed of the turning belt 28 is set to be lower than that of the lower feed belt 26, the operating arm 58 in the correcting unit 56 sequentially advances the path of the subsequent article W with respect to the preceding article W. Since the position is changed from the position closer to the conveyance center of the conveyor toward the outer side of the conveyor, the arrival position to the turning belt 28 sequentially changes in the outward direction, and accordingly, the article W on the upstream side moves toward the inclined portion 28a of the turning belt 28. By setting the arrival position on the upstream side, it is possible to apply a turning force to the article W for a long time, and it is possible to prevent poor turning to a lateral posture when rotating in contact with the preceding article W. At the same time, when the article W is turned, it acts so that the rear side of the article W is rotated toward the front side. To below. In this case, the direction in which the article W is turned by the turning belt 28 is a direction in which the front of the article W is brought close to the conveyor side, so that the processing capacity of, for example, a horizontal bag making and filling machine is about 100 bags / min. Even when the article is supplied, when the article W is subjected to a turning action, the front and back of the article W are reversed by the bullets blown from the turning belt 28, or the alignment cannot be performed sufficiently. It is recommended for high-speed transfer processing because it can be prevented.

  When the traveling speed of the turning belt 28 is set to be higher than that of the lower feed belt 26, the operation arm 58 in the correcting means 56 sequentially advances the path of the succeeding article W with respect to the preceding article W. The position where the front of the succeeding article W comes in contact with the rear of the preceding article W that is in contact with the skewed portion 28a of the turning belt 28 by changing from the direction toward the transport center is closer to the upstream article W. Since the change is made closer to the conveyance center, when an article made of a soft material such as a roll pan rotates in contact with the preceding article W, when the article is in contact with the preceding article W and receives the rotational force of the turning belt 28, the articles Can prevent the subsequent article W from being turned to the horizontal posture and prevented from turning to the horizontal posture. As described above, the correction means 56 is effective when applied to posture change of an article that is soft, such as a roll pan, and the like, and the shape of each article is uneven and the outer surface is formed in an arc.

  Further, since the supply conveyor 40 is configured to place and convey the articles W on the supply belts 42, 42, even if the conveyance direction length of the aligned articles W changes, a large number of supplies There is no need to change the arrangement pitch of the attachments on the conveyor having attachments at predetermined intervals, and the change in the number of articles per row can be flexibly handled. Moreover, even if a conveyance delay occurs in the aligned articles W, the detection means 52 detects the arrival of the articles W and decelerates the transfer speed of the tubular film f, thereby delaying the supply attachment by one pitch. It does not occur, and the production efficiency in the horizontal bag making and filling machine can be improved.

  Further, the guide belts 20 and 20 of the merging conveyor 16, the turning belts 28 and 28 of the attitude changing conveyor 24, and the side belts 44 and 44 of the supply conveyor 40 are configured to be capable of adjusting the distance, so that they can be used in multi-product production. Product switching work can be handled easily and in a short time, and production efficiency can be improved.

[When supplying aligned articles in one row to the supply conveyor]
As shown in FIG. 2, the distance between the pair of turning belts 28 and 28 in the posture changing conveyor 24 is the same as the distance between the straight portions 28b and 28b in the longitudinal direction of the article W (when it is in the horizontal posture). Adjust so that it corresponds to the length in the horizontal direction. In addition, the inclination angle of each guide belt 20 in the merging conveyor 16 is adjusted, and the conveying center of the conveyor reaches a position where the article W fed from the merging conveyor 16 can come into contact with either the left or right turning belt 28 whose distance is adjusted. Set to be able to move toward. Further, the distance between the pair of side belts 44, 44 in the supply conveyor 40 is adjusted in accordance with the distance between the straight portions 28b, 28b in the pair of turning belts 28, 28.

  In the case of supplying one row of aligned articles W, after a predetermined timing when three articles W corresponding to the number of sets in one row are sent out from one row of aligned conveyors 12, three from the aligned conveyor 12 of the other row. Article W is sent out. In other words, the articles W for each number of sets in one row are alternately sent out to the merging conveyor 16 so as to be spaced apart from each other by the alignment conveyors 12 and 12 in each row. The articles W sent from the alignment conveyor 12 on either the left or right side are brought closer to the conveyance center of the conveyor by the guide belt 20 on the same side of the merging conveyor 16 and then sent to the attitude conversion conveyor 24.

  Regarding the displacement of the path of the article W transferred to the lower feed belt 26 of the posture changing conveyor 24, the posture changing, the movement to the conveyance center of the conveyor, and the aligned set, as described above, any one of the merging conveyor 16 The article W fed along the guide belt 20 is moved outwardly of the conveyor by the correction means 56 arranged on the same side depending on the relation between the traveling speed of the turning belt 28 and the traveling speed of the lower feeding belt 26. Sequentially moved or sequentially moved toward the transport center, gathered while changing the posture by the turning belt 28 and the restricting member 36, moved toward the transport center of the conveyor, and aligned in a row for every three. The aligned articles W are sent out toward the supply conveyor 40.

  One row of aligned articles W placed so as to straddle the two rows of supply belts 42, 42 of the supply conveyor 40 is conveyed by a pair of side belts 44, 44 being guided on the left and right sides. The pushing conveyor 46 is operated at the timing when the aligned articles W arrive at a predetermined position, and the pushing member 50 that moves at a speed higher than the conveying speed of the supply conveyor 40 protrudes above the conveying surfaces of the supply belts 42 and 42 to align the aligned articles W. The aligned articles W are pushed to the crossover conveyor 62 and the aligned articles W are fed into the tubular film f formed by the bag making means 60 by the crossover conveyor 62. Thereby, the front and back of the three articles | goods W can contact each other, and can be supplied in the cylindrical film f in the aligned state which became 1 row. Thus, when a roll bread is packaged in two rows and one row in a horizontal bag making and filling machine, generally, in two row packaging, a bag after packaging is used as a packaging form in which a binding tool is attached to a bag mouth after pillow packaging. While the length is set to a dimension with a margin for the contents, in one-row packaging, it is common to have a pillow packaging form that does not use a binding tool. Even when the aligned articles W are formed in a single-row packaging with two rows, a gap is formed between the articles in the course of conveyance, or the assembly length is increased due to disorder of the posture of each article W, Since the gap between the aligned articles W gathered by the push conveyor 46 can be eliminated and the posture can be corrected, the sheets can be fed toward the cylindrical film f. Tight pillow wrap It is possible to obtain the goods.

  Further, when the aligned articles W gathered in one row are supplied to the supply conveyor 40, the same operational effects as in the case of feeding the aligned articles W gathered in two rows described above are obtained. In addition, since the alignment conveyors 12 and 12 are set so as to alternately send out every number of articles in one row, the number of articles is not reduced by only one of the alignment conveyors 12, and the conveying efficiency of both the alignment conveyors 12 and 12 is improved. Can be increased.

  In the article supply apparatus according to the embodiment, the setting of the article conveying operation from the alignment conveyors 12 and 12 to the downstream side is changed, the angle of the guide belts 20 and 20 of the merging conveyor 16 is adjusted, and the turning belts 28 and 20 of the attitude changing conveyor 24 are changed. 28 and the side conveyors 44 and 44 of the supply conveyor 40 can be simply adjusted in a short time to switch between the one-row supply and the two-row supply of the aligned articles W assembled every plurality.

[About collecting and supplying 10 items so that there are no gaps]
In this example, only different operations for the attitude changing conveyor 24 that are basically different from those in the case of supplying the aligned articles W assembled in two rows by the supply conveyor 40 will be described. In this case, the operating arm 58 only needs to be retracted out of the article conveyance path of the lower feed belt 26 to be in a non-operating state. Further, the left and right mutual distances between the downstream position and the upstream position of the turning belt 28 are set wider than the case where the posture changing conveyor 24 is aligned and set in two rows.

  Article W which is in a vertically oriented posture and is delivered to and transported in two rows of five in each row to lower feed belt 26 in posture changing conveyor 24 travels with a speed difference from lower feed belt 26. A turning force is applied that sequentially contacts the belt 28 and changes its posture from vertical to horizontal as described above. At this time, the regulating member 36 is positioned in front of the leading article W in each row and moves at a lower speed than the traveling speed of the lower feed belt 26, and the moving speed is further decelerated temporarily to switch to slow driving. As a result, the article W that has been turned first and the article W that is subsequently transferred to the lower feed belt 26 are temporarily blocked by the regulating member 36. At this time, the article W conveyed by the lower feed belt 26 is pressed against the regulating member 36 and the posture between the articles is disturbed. Further, the articles W of the turning belt 28 disposed on both sides of the lower feed belt 26 are disturbed. The articles W that are in contact with the skewed portion 28 a receive the turning force of the skewed portion 28 a, and the articles W that are conveyed while being aligned in two rows have a gap between the articles while being conveyed by the lower feed belt 26. It is gathered by being pushed to the extent possible. Thereafter, the travel speed of the regulating member 36 is returned to the original speed and moved, so that the transport posture is disturbed and the article W is transported downstream as a set without gaps.

  In this example as well, as described above, setting is made so as to pulsate the forward movement of the regulating member 36 until the articles W are gathered without gaps and during the subsequent conveyance of the articles by the lower feed belt 26. It is preferable to do. In this example, it is preferable to set this pulsation larger than in the other examples.

[Another Example]
In the case of speeding up the packaging process in the horizontal bag making and filling machine, due to the intermittent operation of the regulating means 38, the articles W supplied from the merging conveyor 16 are not sufficiently aligned and arranged by only one regulating means 38. There is a case. FIG. 5 shows another embodiment of the posture changing conveyor 24 that can cope with this, and a plurality of (two in the other embodiment) the lower feed belt 26 and the regulating means 38 (regulating member 36) are continuously connected. It is arranged. In this case, as in the embodiment described above, the turning belt 28 is provided above the upstream first lower feed belt 26a and the posture of the article W is changed by the restricting means 38, whereas the downstream second lower portion is lowered. Above the feed belt 26b, a pair of left and right side belt conveyors having no posture changing function is set to run at the same speed as the second lower feed belt 26b.

  In this way, when a plurality of lower feed belts 26 and a plurality of regulating means 38 are provided in succession, the article W delivered from the merging conveyor 16 to the first lower feed belt 26a on the upstream side turns as in the above embodiment. As described above, the belt 28, the first lower feed belt 26a, and the restriction member 36 convert the vertical posture into the horizontal posture, and the first restriction member 36a that contacts the front side of the leading article W moves forward. Then, the front and rear articles W are conveyed downstream in a gathered state (FIGS. 5A and 5B). Then, the upstream first regulating member 36a moves downward outside the conveyance path and the regulation is released, so that the aligned articles W are delivered to the downstream second lower feed belt 26b (FIG. 5 (c)). ), (d)). The aligned articles W conveyed by the second lower feed belt 26b are conveyed to the downstream side while maintaining the alignment posture with the side portions being guided by the side belt conveyor that travels at the same speed as the second lower feed belt 26b. Further, the second regulating member 36b that contacts the front side of the leading article W moves forward at a lower speed than the second lower feed belt 26b and the side belt conveyor, and then moves downward outside the conveying path to release the regulation. W is delivered toward the supply conveyor 40 (FIG. 5E). That is, the first restricting member 36a, the turning belt 28, and the first lower feed belt 26a perform an aligned set in which the articles W are turned horizontally by a predetermined number, and the second restricting member 36b supplies the supply conveyor 40 of the horizontal bag making and filling machine. The aligned articles W can be sent out at predetermined intervals corresponding to the high-speed processing. Note that the intermittent operation control of the regulating means 38 is the same as in the above-described embodiment. Further, the number of sets of the lower feeding belt 26 and the regulating means 38 that are continuously arranged is not limited to two, and the number may be selected according to the packaging processing capability in the horizontal bag making and filling machine. In another embodiment, it is preferable that the correcting means 56 is disposed upstream of the turning belt 28.
