JP 2004-314980 A (page 5-9, FIG. 1-7) Japanese Examined Patent Publication No. 7-77881 (page 3-5, FIG. 1-5)

  In both the cartoner described in Patent Document 1 and the cartoner described in Patent Document 2, after an article is sucked and lifted, it is horizontally moved and inserted into a carton that is horizontally separated from the sucking position. However, in designing a car toner, a layout in which an adsorbed article is directly lowered and inserted into a carton may be required. In such a case, the device examples disclosed in Patent Documents 1 and 2 cannot be referred to.

  The present invention has been made in view of the above points, and in a car toner that requires a layout in which an article is extruded above a carton, the article is lowered and inserted into the carton, the article is reasonably inserted into the carton with a correct posture. The purpose is to be able to. It is another object of the present invention to prevent as much as possible a situation in which an end of an article is caught in the carton and causes a defective insertion when inserting an article row in which a plurality of articles are arranged in parallel.

The cartoner according to the present invention has the following configuration. That is, a shutter that is disposed above a carton having an open top surface and that can slide in a horizontal direction, and a shutter drive that moves the shutter between an advanced position that covers the carton and a retracted position that exposes the carton. Apparatus, vacuum suction type transfer chuck disposed above the carton and shutter, an elevating device for raising and lowering the transfer chuck, and an extrusion device for extruding articles onto the shutter when the shutter is in the advanced position And a command for lowering the transfer chuck toward the article on the shutter and a command for attracting the article to the transfer chuck that has reached the article. issues a shutter save command, thereafter further lifting device, it issues a transfer chuck drop command for inserting the articles into the carton DOO In the after issuing a command to adsorb the article to transfer the chuck, issues an instruction to increase the transfer chuck is then the shutter drive controller issues a shutter save command to.

  According to this configuration, the article is once pushed onto the shutter, and the article is attracted to the transfer chuck while the article is properly held by the shutter, so that the suction is surely performed and the article falls due to poor suction. There is nothing. Also, since the transfer chuck chucks the article after the shutter is slid, the article is tilted from the side where the shutter is no longer supported, and the article does not fall into the carton in that state, resulting in poor storage. Can be inserted.

Further , since the shutter is slid while the article is lifted from the shutter, there is a situation in which the scratch mark of the shutter remains on the surface of the article, the article falls due to friction with the shutter, or the sliding of the shutter is inhibited. Does not occur. As a result, the relationship between the article and the shutter can be broken without difficulty.

According to the present invention, in the cartoner configured as described above, the actuator of the lifting device is configured as follows. That is, the actuator of the lifting device comprises a first air cylinder having a large stroke and a second air cylinder having a small stroke connected in series, and the second air cylinder is reduced at the stage of adsorbing the article to the transfer chuck and lifting it. In the step of inserting an article into the carton, the overlapped reduction of the first air cylinder and the second air cylinder is used.

  According to this configuration, only the second air cylinder with a small stroke is operated in a situation where only a small amount of elevation is required, and the reduction of the first air cylinder and the reduction of the second air cylinder are superimposed on each other in a situation where a large amount of elevation is required. Therefore, it is possible to provide an inexpensive apparatus that is simple in configuration and control.

According to the present invention, in the cartoner configured as described above, the article is obtained by enclosing the contents in an envelope-shaped package, and the extrusion device arranges a plurality of articles standing side by side in the package in parallel. The product is extruded onto the shutter as an article row, and an angular bending device for bending the package end of the article row to the inside of the article row is disposed on the shutter.

  According to this configuration, since the package end of the article at the end of the article row is bent inside the article row by the angle bending device, the insertion of the article is not hindered by the package end being caught by the corner of the carton. .

  According to the present invention, a shutter that slides in a horizontal direction is placed above a carton, an article is pushed out onto the shutter, the shutter is retracted while the article is adsorbed to the transfer chuck, and then the transfer chuck is lowered. The article is inserted into the carton, and the article is adsorbed to the transfer chuck while the article is properly held by the shutter, so that the adsorption is reliably performed and the article falls due to poor adsorption. Absent. Also, since the transfer chuck chucks the article after the shutter is slid, the article is tilted from the side where the shutter is no longer supported, and the article does not fall into the carton in that state, resulting in poor storage. Can be inserted.

  An embodiment of the present invention will be described with reference to FIGS. 1-20. FIG. 1-6 is a plan view of the main part of an article transfer device placed as a pre-process element of cartoner, and shows different operation states, and FIG. 7-10 is an operation explanatory diagram of an extrusion plate of the article transfer device. FIG. 11-17 is an explanatory view of the operation of the push-out bar of the article transfer device and the transfer chuck of the cartoner, and shows different operation states, and FIG. 18 is an article transfer device. FIG. 19 is an explanatory diagram of the supply of articles to the bucket conveyor of the article transfer apparatus, and FIG. 20 is a control block diagram.

  The article transfer device 1 is combined with the cartoner 100 as a pre-process element. The article transfer apparatus 1 includes the following components. That is, the bucket conveyor 10 that conveys the article 2, the intermediate holding unit 20 that receives the article 2 from the bucket conveyor 10, the first extrusion device 30 that pushes the article 2 from the bucket conveyor 10 to the intermediate holding unit 20, and the article that the intermediate holding unit 20 has received. 2 is a second extrusion device 40 that pushes 2 to the cartoner 100 with the extrusion bar 41.

  The bucket conveyor 10 is provided with a plurality of buckets 11 continuously in the traveling direction of the endless chain 12. A plurality of partition plates 13 are arranged on the endless chain 12 so as to intersect at right angles to the extending direction of the chain (see FIG. 19). The partition plate 13 is attached to the endless chain 12 at a predetermined pitch, and the space between the front and rear partition plates 13 constitutes the bucket 11.

  The buckets 11 are not continuous on the endless chain 12, but are composed of the same number of buckets 11 as one unit of goods packed in a carton, which will be described later, and the groups are arranged at predetermined intervals. Yes. The number of articles per unit is 8 in this embodiment, but this is merely an example, and any number may be used as long as it is plural. The articles 2 are individually held for each of the buckets 11 in a state where the articles 2 are erected with one side face down.

  Each partition plate 13 is erected so as to be normal to the travel line of the endless chain 12. Therefore, the width of the bucket 11 is the same width in the straight section of the endless chain 12 on both the base side and the front end side. However, when the pulley 11 reaches the pulley 14 at the end of the conveyor, the travel line of the endless chain 12 draws a circular arc. It opens from the root side (see FIG. 19). Since it is easier to put the article 2 when the tip of the bucket 11 is open, the article 2 is thrown in aiming at this point.

  When putting the article 2 into the bucket 11, a belt conveyor 15 shown in FIG. 19 is used. Although the article conveyance surface of the belt conveyor 15 is initially horizontal, the angle of a roller (not shown) that supports the belt conveyor 15 is gradually changed so that the belt conveyor 15 is gradually twisted and comes closest to the bucket 11. At the time, it is inclined at the same angle as that of the partition plate 13. For this reason, the article 2 smoothly transfers to the bucket 11. A guide plate 16 is attached to the belt conveyor 15 to prevent the articles 2 from slipping down from the article conveying surface where the inclination gradually becomes steep.

  An intermediate holding unit 20 made of block-like metal is disposed on the side of the bucket conveyor 10 and fixed to a non-illustrated immovable member. The intermediate holding part 20 is formed with a plurality of horizontal groove-shaped article receiving parts 21 at the end adjacent to the bucket conveyor 10. The number thereof is the same as that of the group of buckets 11, that is, eight, and that many are arranged in parallel to each other at the same pitch as the buckets 11. The height of the bottom surface of the article receiving unit 21 is the same level as or slightly lower than the bottom surface of the bucket 11.

  The eight article receiving portions 21 merge near the end opposite to the bucket conveyor 10 to form one discharge path 22. The width of the discharge path 22 is narrower than the interval between the eight article receiving portions 21 located at both ends, and the eight articles 2 come into contact with each other when they reach the discharge path 22. One of the inner side walls of the article receiving portions 21 at both ends constitutes a tapered guide 23 that guides the article 2 to the discharge path 22.

  The bucket conveyor 10 stops for a predetermined time when the eight buckets 11 that individually hold the articles 2 are aligned with the eight article receiving portions 21. During this stop period, the first extrusion device 30 pushes the article 2 from the bucket 11 to the intermediate holding unit 20.

  The structure of the 1st extrusion apparatus 30 is demonstrated referring FIG.1 and FIG.7. The first extrusion device 30 includes a comb-like extrusion plate 31. The extrusion plate 31 is formed with a total of eight hanging parts 31 a that enter the bucket 11 and the article receiving unit 21, and push out the eight articles 2 together. A horizontal beam 32 is attached to the extrusion plate 31 so as to form a T shape when viewed from above.

  The beam 32 is horizontally supported by a parallel link mechanism 33. The two links 34 constituting the parallel link mechanism 33 have an upper end connected to the beam 32 and a lower end connected to the slider 35. The slider 35 moves up and down along a guide 36 fixed vertically. When the slider 35 moves up and down, the link 34 connected to the slider 35, the beam 32 supported by the link 34, and the pushing plate 31 also move up and down. The vertical movement is caused by a crank disk 38 connected to one link 34 by a pin 37.

  The first extrusion device 30 waits for the arrival of the bucket 11 while keeping the extrusion plate 31 at the height of FIG. 7, that is, the height at which the tip of the hanging portion 31 a is slightly above the bottom of the bucket 11. When the bucket 11 arrives and stops, the crank drive motor 39 shown in FIG. 20 rotates the crank disk 38 clockwise in FIG. Then, as shown in FIG. 8, the slider 35 is lowered while the link 34 is rotated counterclockwise to send the beam 32 to the left.

  In the process in which the pin 37 moves from the position shown in FIG. 7, that is, the position closest to the right, to the position shown in FIG. 8, ie, the position closest to the bottom, the slider 35 is displaced downward. On the other hand, the upper end of the link 34 is displaced upward as the link 34 rises from the inclined state as shown in FIG. 7 as shown in FIG. The downward displacement of the slider 35 and the upward displacement of the upper end of the link 34 cancel each other, and the upper end of the beam 32 moves approximately horizontally. Therefore, the extrusion plate 31 draws an approximately horizontal locus as shown in FIG.

  After the state of FIG. 8, the slider 35 starts to rise. A little later than that, the upper end of the link 34 turns downward. Ascending and descending cancel each other, and the beam 32 continues approximate horizontal movement. The extruded plate 31 also continues to draw an approximately horizontal trajectory.

  In the state of FIG. 9 in which the pin 37 is at the leftmost position, the horizontal movement of the beam 32 reaches its limit. At this point, the article 2 has completely moved from the bucket 11 to the article receiving unit 21. When the crank disk 38 continues to rotate clockwise, the slider 35 is displaced upward, and the upper end of the link 34 is also displaced upward as the link 34 shifts from the angle of FIG. 9 to the angle of FIG. Two types of upward displacement overlap, and the beam 32 is greatly lifted upward. Accordingly, the push-out plate 31 passes above the hanging portion 31a without being hooked on the bucket 11 and returns to the position shown in FIG. Since there is no problem even if the bucket conveyor 10 is moved in the state of FIG. 10, the pull-back of the push-out plate 31 and the forward movement of the bucket conveyor 10 can be advanced simultaneously to shorten the tact time.

  The first pushing device 30 gives a kind of gate motion to the pushing plate 31 only by the rotation of the crank disk 38, but this structure is only one example. For example, a similar locus can be drawn on the extrusion plate 31 by combining a horizontal linear motion mechanism and a vertical linear motion mechanism.

  The article 2 received in the article receiving unit 21 is pushed out to the tip of the discharge path 22 by the pushing bar 41 that is horizontally supported parallel to the bucket conveyor 10. The structure of the 2nd extrusion apparatus 40 which moves the extrusion bar 41 is demonstrated referring FIG.1, FIG.11, FIG.18.

  The second extrusion device 40 includes a first crank 42 that rotates in a vertical plane that intersects the bucket conveyor 10 at a right angle. The first crank 42 is supported by the output shaft of the speed reducer 44 combined with the motor 43. The first crank 42 supports the second crank 45 at its tip. The second crank 45 rotates in a vertical plane parallel to the rotation plane of the first crank 42. A slider 46 is attached to the tip of the second crank 45 so as to be slidable in the axial direction of the second crank 45. The slider 46 is moved by an actuator 47 (see FIG. 20) such as an air cylinder or a linear motor, and changes its position relative to the second crank 45. The push bar 41 protrudes from the mounting plate 48 supported by the slider 46. The push bar 41 is arranged so as to extend over all of the eight component receiving portions 21.

  A sun pulley 50 is disposed at the center of rotation of the first crank 42. The sun pulley 50 is fixed to the immovable member so as not to rotate. On the other hand, a planetary pulley 51 is arranged at the rotation center of the second crank 45. The planetary pulley 51 is fixed to the second crank 45 so as not to rotate, and rotates together.

  The sun pulley 50 and the planetary pulley 51 are connected by a belt 52 wound around both. The sun pulley 50 and the planetary pulley 51 are timing pulleys, and the belt 52 is also a timing belt. The number of teeth of the sun pulley 50 is set to twice the number of teeth of the planetary pulley 51.

  Outside the outlet of the discharge path 22, a cartoner 100 for inserting the article 2 into the carton 101 having an open top surface is arranged. The main components of the cartoner 100 are a shutter 110 and a vacuum suction type transfer chuck 120.

  The shutter 110 is composed of a horizontal plate placed under the intermediate holding unit 20, and slides in a horizontal direction between an advanced position protruding from the intermediate holding unit 20 and a retracted position drawn under the intermediate holding unit 20. Is possible. The shutter 110 covers the upper surface of the carton 101 at the advanced position and exposes the carton 101 upward at the retracted position. The shutter 110 is moved by a shutter driving device 111 using an air cylinder or a linear motor as an actuator.

  An angular bending device 112 for the article 2 is provided for the shutter 110 at the advanced position. The article 2 is obtained by enclosing the contents in an envelope-shaped package, and is placed with the side of the package facing down and the bonded portions at both ends facing sideways. If eight such articles 2 are arranged side by side, the package ends of the articles 2 located at both ends of the article 2 may be caught by the corners of the carton 101, leading to an insertion error. It is the role of the corner bending device 112 to avoid this.

  The corner bending device 112 has a planar U-shaped frame 113 fixed above the position where the shutter 110 is advanced. The frame 113 is arranged with the opening portion directed toward the discharge path 22, and slopes 114 are formed at the corners on both sides at the back so as to form chamfered portions. A rotating plate 115 is disposed on both sides of the entrance of the frame 113. The rotating plate 115 is rotated in the vertical plane by the angle bending actuator 116 shown in FIG. 20 from the angle in the article acceptance state shown in FIG. 1 to the angle in the article angle bending state shown in FIG. The package end of the positioned article 2 is folded inside the article row.

  The transfer chuck 120 adsorbs eight articles 2 taken into the angle bending device 112 at a time, and one article with a plurality of (two in the embodiment) suction holes arranged at intervals. 2 is adsorbed. The transfer chuck 120 is connected to a vacuum source 122 through a valve 121 and is moved up and down by an elevating device 130.

  The lifting device 130 includes a bracket 131 that supports the transfer chuck 120 and an actuator 132 that lifts and lowers the bracket 131. The actuator 132 is configured by connecting in series a first air cylinder 133 whose axis is vertical and a second air cylinder 134 whose axis is also vertical. The rod of the first air cylinder 133 is connected to the fixed portion, and the rod of the second air cylinder 134 is connected to the bracket 131. When the strokes of the air cylinders are compared, the first air cylinder 133 has a large stroke, and the second air cylinder 134 has a small stroke.

  The article transfer apparatus 1 and the cartoner 100 include a control system as shown in FIG. The control unit 200 that forms the center of control includes, as controlled elements on the article transfer device 1 side, a conveyor motor 17 that drives the bucket conveyor 10, a conveyor motor 18 that drives the belt conveyor 15, and a crank of the first extrusion device 30. The drive motor 39 and the motor 43 of the second extrusion device 40 and the actuator 47 are connected. Further, as controlled elements on the side of the car toner 100, a shutter driving device 111, a corner bending actuator 116, a valve 121, a first air cylinder 133 and a second air cylinder 134 of the elevating device 130, and a conveyor that supports the carton 101 (not shown). ) Conveyor motor 102 is connected. In addition, the operation unit 201 for inputting a driving command, various sensors for confirming the presence and state of the article 2 and the carton 101, and other components that require control by the control unit 200 are connected.

  Next, operations of the second extrusion device 40 and the cartoner 100 will be described. When the first pushing device 30 pushes the article 2 from the bucket conveyor 10 into the article receiving unit 21 of the intermediate holding unit 20, the second pushing device 40 keeps the pushing bar 41 at the position shown in FIG. Seen from above, it looks like Figure 2. This is the first position of the push bar 41. The push bar 41 in the first position serves to prevent the article 2 from overrunning forward.

  The control device 200 issues an article pushing command to the second pushing device 40 as the pushing plate 31 is retracted by the operation of FIG. Then, the motor 43 is driven, and the first crank 42 fixed to the output shaft of the reduction gear 44 rotates clockwise as seen in FIG. On the other hand, a counterclockwise rotation occurs in the second crank 45 that is supported at the tip of the first crank 42 and is connected to the stationary pulley 50 by the belt 52 with the planetary pulley 51 fixed to itself. At this time, the control device 200 gives a motion corresponding to the rotation angle of the second crank 45 to the actuator 47 so that the push bar 41 does not push back the article 2, and the slider 46 is connected to the connecting portion of the first crank 42 and the second crank 45. Slide toward. As a result, the extrusion bar 41 draws a trajectory that is lifted diagonally from the first position (symbolized by the circled number “1” in the figure) and moves in the horizontal direction, and moves above without touching the article 2. To do.

  When the push bar 41 crosses the article 2, the control unit 200 drives the actuator 47 again and slides the slider 46 to the tip side of the second crank 45. Then, the extrusion bar 41 turns around behind the article 2 as shown in FIG. This is the second position of the push bar 41 (in the figure, this is symbolized by a circled number “2”). Seen from above, it looks like Figure 3.

  After the push bar 41 reaches the second position, the control unit 200 reverses the rotation direction of the motor 43. Then, as seen in FIG. 14, the first crank 42 rotates counterclockwise and the second crank 45 rotates clockwise, and the pushing bar 41 pushes the article 2 from behind and moves to the left in the figure. Let The control unit 200 drives the actuator 47 so that a certain distance or more is maintained between the push bar 41 and the intermediate holding unit 20 so that the push bar 41 does not contact the intermediate holding unit 20.

  The eight article receiving units 21 of the intermediate holding unit 20 are individually separated at the beginning, but merge together in the middle to become one. At the same time, since the tape enters the region of the tapered guide 23, the eight articles 2 are pushed toward the left by the push-out bar 41 and approach each other, and become dense around the discharge path 22. The pushing bar 41 pushes the article 2 in a dense state into the upper surface of the shutter 110, which is a delivery position to the transfer chuck 120, and into the corner bending device 112 as shown in FIG. The position at the time of completion of pushing is defined as a third position of the push bar 41 (in the figure, this is symbolized by a circled number “3”). When viewed from above, it looks like FIG. At this time, needless to say, the shutter 110 is in the advanced position, and the transfer chuck 120 is held upward at this stage as shown in FIG.

  When the eight articles 2 are arranged in a horizontal row and pushed into the corner bending device 112, the front package ends of the articles 2 located at both ends hit the inclined surface 114 and are bent inside the article row. After that, when the rotating plate 115 rotates as shown in FIG. 5, the rear package end of the article 2 whose front package end is bent by the inclined surface 114 is bent inside the article row by the rotating plate 115.

  After the article 2 is taken into the corner bending device 112, the control unit 200 drives the motor 43 and the actuator 47 to return the push bar 41 from the third position to the first position as shown in FIG. The extrusion bar 41 draws a locus as shown in FIG. 15 until it starts from the first position and returns to the first position. Similar to the pushing plate 31 of the first pushing device 30, this movement of the pushing bar 41 can also be realized by a mechanism other than the illustrated mechanism, for example, a combination of a horizontal linear motion mechanism and a vertical linear motion mechanism.

  Further, the control unit 200 issues a lowering command to the lifting device 130 and lowers the transfer chuck 120 toward the article 2 on the shutter 110. When the transfer chuck 120 reaches the article 2 and contacts the upper surface of the article 2, the control unit 200 issues a command for causing the transfer chuck 120 to attract the article 2 and opens the valve 121. Then, the transfer chuck 120 adsorbs the article 2 with a vacuum pressure. Then, the control unit 200 issues a rising command to the lifting device 130. The transfer chuck 120 rises and lifts the article 2 as shown in FIG. Up and down of the transfer chuck 120 so far is performed by reducing and extending the second cylinder 134 having a small stroke. Since the article 2 is attracted to the transfer chuck 120 in a state where the article 2 is properly held by the shutter 110, the adsorption is surely executed, and the article 2 does not fall due to poor adsorption.

  When the article 2 is lifted, the control unit 2 issues a shutter retract command to the shutter driving device 111. Then, the shutter driving device 111 retracts the shutter 110 as shown in FIG. This opens a way to insert the article 2 into the carton 101.

  Since the transfer chuck 120 slides the shutter 110 after the article 2 is adsorbed, the article is not tilted from the side where the shutter 110 is unsupported, and does not fall into the carton in that state, resulting in poor storage. Thereby, the article 2 can be inserted into the carton 101 in a correct posture.

  Further, since the shutter 110 is slid while the article 2 is lifted from the shutter 110, the scratch mark of the shutter 110 remains on the surface of the article 2, the article 2 falls due to friction with the shutter 110, or the sliding of the shutter 110 is obstructed. Thus, the relationship between the article 2 and the shutter 110 can be cut off without difficulty.

  Subsequently, the control unit 200 issues a lowering command to the lifting device 130. The lowering command this time reduces not only the second air cylinder 134 but also the first air cylinder 133. As a result, a large lowering stroke in which the strokes of both air cylinders are superimposed on the transfer chuck 120 occurs, and the article 2 is inserted all at once to the bottom of the carton 101 as shown in FIG. As described above, since the package ends of the articles 2 at both ends of the row are bent inside the row of articles, the package ends are not caught by the corners of the carton 101 and the insertion of the articles 2 is not hindered. In addition, since the article 2 is securely adsorbed to the transfer chuck 120, the article 2 can be inserted into the carton 101 in a correct posture.

  After putting the article 2 into the carton 101, the control unit 200 closes the valve 121 and separates the transfer chuck 120 from the article 2. Then, a lifting command is issued to the lifting device 130, and the transfer chuck 120 is lifted to the height shown in FIG. Then, a shutter advance command is issued to the shutter driving device 111, and the shutter 110 is returned to the advanced position. The angle bending actuator 116 is also commanded to return the rotating plate 115 from the angle shown in FIG. 5 to the angle shown in FIG. Further, the carton containing the articles 2 is moved to the downstream side of the conveyor, and a new empty carton 101 is placed under the shutter 110. This prepares for the next article carton packing.

  Although the embodiments of the present invention have been described above, various modifications can be made without departing from the spirit of the invention.

    The present invention can be widely used as an article transfer device when a plurality of articles are boxed in a carton or a case.
