The present invention relates to a packaging machine.

Known machines for loading a plurality of objects through one or both ends of a sleeved carton have dimensions and structures that require considerable spacing between and after the loading operation. This interval, of course, imposes a significant limit on the amount of cartons that can be loaded over a period of time. Often these types of machines operate at extremely high speeds to compensate for the drawbacks of loading and then spacing the cartons widely apart. Of course, high speed operation results in a high degree of wear and substantially increases downtime, increasing repair and maintenance costs.

The sleeved blank with the open end is folded and placed in the hopper, from which the cartons are sequentially released, and the electric blank has glue laps which are often difficult to assemble, because the reasons for the difficult This is because the glue performs unnecessary joining with the panel of the carton disposed in front in contact with it. This type of carton also tends to bend downwards to prevent effective escape.

According to the present invention, the sleeve-type carton with the open end is continuously fed from the hopper and controlled by an improved feeder means, where unnecessary bonding due to the glue used in the glue wrap in surface contact with the panel is cut off. In addition, the carton is steered during the breakaway operation to partially assemble when stripped from the feeder mechanism. Immediately after the stripping operation, the carton is moved along the loading path by a pusher means that can vibrate synchronously, and the electric pusher opens the end of the assembled carton to move between the pair of moving flight bars. In the advancing direction, the width of the flight bar is approximately equal to the gap between the trailing panel of one carton and the leading panel of the next carton, so that unnecessary gaps of moving cartons are continuously removed.

The invention will now be described in more detail in connection with the accompanying drawings.

As shown in Figs. 1 and 2, the frame of the machine is indicated by F, and two rows of articles as indicated by A1 and A2 enter the inlet end of the machine on the feed conveyor 1 and then the moving conveyor ( 2) is placed on. The movement speed of the article A1 is controlled by the known method, starwheel 2, while the movement of the article A2 is controlled and improved by the forming wheel 3. A plurality of spacer wedges 7 on the endless element 4 which is rotatably supported on the rotating elements 5 and 6, one of which is an actuating element and the other of which is an idler element. ), Which moves into the space between any of the articles A1 and divides the articles into grooves at regular intervals. Similarly, a plurality of spacer wedges 11 are installed on the endless element 8 supported on the rotating elements 9 and 10 (one of which is an actuating element), which allows the articles A2 to be spaced at regular intervals. Divided into having groupings. After arranging the sores into six grooves, for example three articles A1 and three articles A2, they are passed downwardly between the guides 12 at regular intervals to exit 12A of the guide 12. It dripped through the one open end of the granulated carton arrange | positioned at. The carton is under the control of a plurality of flight bars 13 during and before the dripping operation on the sleeve and during the end closing operation, and the electric bar moves synchronously with the other elements of the machine in a known manner. The end of the flight bar 13 is fixed to a chain with a constant spacing which is installed on the sprocket in a known manner.

In order to close the end of the carton after dropping, a rotating element 14 having a lock engaging with the radially elongated probe 15 causes a locking action on the closing panel at one end of the carton. .

Other aspects of the machine are the same as described above, the parts of which will be briefly described in the following. For example, the articles A3 and A4 are brought to the feed end of the machine on the feed conveyor 16 and then transferred to the conveyor 17, while the forming wheels 18 and 19 move the goods on the conveyor 17. Determine the speed. The article A3 is spaced into the groove by the endless element 20, which is supported on a rotating element such as the sprockets 21 and 22, after which the spacer wedges 23 bark the groove. Is placed. Similarly, the endless element 21 is movably supported by the rotating elements 24 and 5, and a series of spacer wedges 26 are provided for grouping the article A4 as described above. The guides 27 are arranged with their discharge ends 27A adjacent to the moving passages of the sleeves having the open ends, the electric sleeves being under the control of the flight bars 13 at regular intervals, and the electric bars Moves from left to right to drop the article of the sleeved carton in which the articles A3 and A4 have the same open end and the end facing each other with the end where A1 is loaded. After the grooves are formed in the closed state, they are closed by a rotating closing element 28 having a lock engagement probe 29 radially disposed with the closing panel at the end of the carton loading the articles A2 and A3. Of course, all of the parts are operated synchronously so that the carton is in the finished state when it leaves the rotating elements 14 and 28.

The carton C having the folded opening end is placed in the hopper 30 above the conveyance passages of the articles A1 and A4 on the one side and the articles A3 on the other side. The carton feeding means, generally indicated by the number 31, is speculatively installed in the pivot 32, and the foremost carton (C) in the hopper 30 by suitable means not shown in Figs. Engage and operate in a vibrating fashion to dislodge it. The folded blank is released from the hopper and at least partly opened during the detachment operation by the downward movement of the feeder means 31, wherein the electric feeder means has a cam surface of the cam 33 on which a portion of the carton is fixed. 33A) to impart rotational movement to the carton panel, and the electric carton panel is folded and connected to the wall of the carton to be engaged by the feeder means 31. The detached caraton is shown as C1.

By installing on a set of endless elements 13A arranged on both sides of the machine, the cartons marked C1 are moved into the space between the set of flight bars 13 with a set of regular intervals that are moved from left to right during the dripping and closing operation. For this purpose, the vibration pusher 34, which is installed speculatively at 35 and moves from left to right with respect to the pivot 35 by appropriate means, is engaged with the rear side of the carton C1. When the vibratory movement of the pusher 34 continues to the right, all of the cartons are engaged with the flight bar 13 disposed at the left end of the operation zone or the upper zone of the endless element 13A. As shown in Figs. 1 and 2, the continuous movement of the operating zone of the element 13A to the right and the continuous incremental movement clockwise around the pivot 35 of the pusher element 34 result in a carton C1. It has a position between two flight bars 13 indicated by C2 in FIG. During the packaging operation of this shape, the closed end flap of the carton is grooved upward by the fixed guides 36 and 37, and has a set of radially arranged probes 40 and 41. Rotating prebrake elements 38 and 39 allow the locking tabs formed in the upper end closure panel to initiate rotational movement from the plane of their joined panel and into a suitable spherical shape in the cooperative closure panel. Adjust the tab for the next insertion.

Figure 3 shows a sleeve-type carton with an open end comprising a manufacturer's glue joint and having an end closure panel and their associated locking means. The machine and method of the present invention are particularly suitable for using the carton of FIG. The carton has a wall panel 45 which is folded and joined to the wall panel 47 along the fold line 46 and is folded and joined to the back panel 49 along the fold line 48. The wall panel 49 has an overlapping panel which forms a glue joint at the middle of the wall 49, and the electric glue joint is indicated by 49A. The wall panel 50 is folded and connected to one side of the panel 50 and 45 along the wall panel 56 along the fold line 51. The locking tab 57 is folded into the panel 53 and cooperates with the locking hole 58 formed in the panel 54. Flaps 59 and 60 are folded and connected to corresponding ends of walls 47 and 49. The glue joint 60A is simply a continuation of the joint shown by 49A, and consists of overlapping edge portions of the upper and lower portions of the flap 60.

At the other end of the carton, the closing panel 61 is folded and connected to the wall 50 along the fold line 62, while the closing panel 63 is connected to the wall 45 along the fold line not shown in FIG. 3. Fold and connect The locking tab 64 is folded and connected to the closing panel 61 and a locking hole such as 58 is formed in the closing panel 63, but this is not shown in FIG. The flap 65 folds and connects to the end of the wall 47 and similarly folds and connects the flap not shown in the figure to the corresponding end of the panel 49. A pair of gripping holes 66 and 67 are formed in panel 49 and the strip of material therebetween is doubled because of the glue wrap 49B forming part of the wall 49. For a more complete description of the carton 47 and its closure means, see U. S. Application No. 560,956, filed Mar. 21, 1975.

The folded carton C in the hopper 30 arranges the panel 45 and 49 on the same plane to form the bottom panel of the loaded carton. In other words, a suitable position for folding the panels 47 and 49 in the same direction as the clock hands around the fold lines 46 and 48 to insert the circatone into the hopper 30 as shown in FIG. Is placed. When inserted in this way, the fold line 46 engages the back wall 30A of the hopper 30 and the fold line 52 is adjacent to the front wall 30B of the hopper 30.

The dimensions of panel 45 between fold lines 46 and 48 are generally the same as the dimensions of panel 49 between fold lines 48 and 52. Thus, when the cartons are deposited in the hopper 30, the cartons tend to bend particularly downward because the panels 45 and 49 are connected by the fold line 48. In addition, the glue from the glue wrap 49A often adheres to a surface that contacts the inner surface of the panel 50 when the carton is folded and secured to the panels 50 and 50 with each other. For this reason, it is difficult to fold the carton in a properly assembled state such as indicated by C2 in FIG.

According to the above-described feature of the sleeve-type carton as shown in FIG. 3, a feeding device means is provided in accordance with the present invention. As best shown in FIGS. 4-8, the main feeder arm 70 is installed to rotate around a fixed pivot 32, and a plurality of suction cups 72 are installed at the right end thereof, A vacuum is used in the manner of, and the main feeder arm 7 is engaged with the panel 45 when it rotates counterclockwise around the fixed pivot 32. Main feeder arm 70 imparts actuation motion by arm 73 integral with arm 70, where actuating link 740 is pivoted at 75. This link is fixed shaft 74. It is pivoted on a rotary actuating element 77 disposed around and rotated by any suitable means, and this link is positioned around the fixed shaft 74 and left by a rotary actuating element 77 which is rotated by any suitable means. The actuating link 76 is pivotally connected to the actuating element 78 at 74. The rotation of the actuating element 76 is thus about the center of the oscillation 32 of the main feeder arm 76. Vibration rotational motion is provided to cause the suction cup 72 to move to engage the panel 45 of the foremost carton C in the hopper 30. The downward movement of the suction cup 72 deviates the lowest carton from the hopper. This causes the cam surface 33A to be disposed at an angle to the generally downward movement of the suction cup 72. Is rotated in cooperative engagement with the carton opening means in the form of a pair of stationary cams 33. Since the suction cup 72 engages with the panel 45, the downward movement of the feeder arm 73 causes The sides 52 extend across the cam surface 33A to transmit rotational movement to the panel 49 in the counterclockwise direction around the fold line 48 and at the same time counterclockwise around the fold line 46. The panel 47 is rotated so that the carton C is partially assembled due to the cooperative action of the main feeder arm 70 and the cam surface 33A as generally shown in FIG.

The branch panels 45 and 49 tend to bend downward, and the glue causes unnecessary adhesion between the panel 49 and the surface contact panel 50 thereof, so that the upper panels 47 and 50 are in turn lowered. It is necessary to prevent downward bending of the panels 47 and 50 during the initial stage of the Karon feeding operation, and also to prevent the bending between the glued points in the panel 49 and the inner surface of the panel 50. It is necessary to break any glue that may form on the body.

In order to give upward force on the panels 47 and 50 when the panel 45 is pulled downward, the refill feeding device arm 81 is pivoted on the main feeding device arm 70 so as to be pivoted at the pivot 82. Install. This arm has a pair of upwardly projecting fingers 83 arranged to enter the gripping holes 67 and engage with the bottom surface of the panel 50. The supplementary feeder arm 81 is arranged with its protruding finger 83 which is in tangible contact with the panel 50 when the rotational movement of the main feeder arm 70 starts to rotate in the same direction as the clockwise direction of the main feeder arm 70. And 49 are rotated slightly downward while the panel 50 is held in its normal position in the hopper 30 to perform initial assembly of the carton.

In order to keep the supplementary feeder arm 81 upward on the panel 50 to produce the desired action, the arm is connected by an actuating link 84 and its right end pivoted at 85. A spring 86, which is connected to the arm 81 and is eccentrically compressed, is disposed around the actuating link 84, and at its left end is engaged with the shoulder 87 integrally formed on the actuating link 84, and the right side. At the end is engaged with the bracket 88 attached to the pulse feeding device arm 70, through which the operation link 84 slides through a hole formed in the bracket 88, not shown. The left end of the actuating link 84 is pivoted on the rotary link 90 at 89, which in turn vibrates around the pivot 32, which is also the pivot for the main feed arm 70. The left side of the upper end of the rotary link 90 engages with the fixed stop 91.

From the above description of the device associated with the main feeder arm 70 and the supplementary feeder arm 71, the parts in the position shown in FIG. 4 are clocked around the pivot 32 of the main feeder arm 70. Rotational movement in the same direction as the needle is supplementary feed around the pivot connection point 82 with the main feeder arm 70 due to the eccentricity of the compression spring 86 acting on the shoulder 87 of the motion link 84. This involves the rotation of the device arm 81 counterclockwise. Thus, when the main feeder arm 70 rotates in the same direction as the clock hands around its pivot 32, the supplemental feeder arm 81 rotates counterclockwise around its pivot 82, When the panel 45 of the lowest carton 45 is pulled downward, the force exerted by the elongated fingers 83 that the panel 50 contacts the inner surface of the panel 50 through the gripping holes 67 Due to this, it is maintained in the normal position in the hopper. Thus, as shown in FIG. 5, the coordination of the main feeder arm 70 and the supplemental feeder arm 81 partially assembles the carton from the folded state in the hopper 30 as shown in FIG. Make sure you leave it in place.

Once the carton is partially assembled by disengaging from the hopper due to the action of the feeder arm and the action of the cam surface 33A, the carton is moved to the lowest position shown in Figure 6, where Placed in the government of the fixed carton stripper indicated at 92) and occupying the position indicated at Cl. As evident in FIG. 8, the carton stripper 92 is generally U-shaped with a hole disposed in the middle thereof and has a space 93 through which the actuating arm 70 and the actuating link 84 are coupled. May move to have a position under the stripper 92 as shown in FIG. This action, of course, allows a carton, such as C1, to be separated from the suction cup 72, allowing the carton to be immediately synchronized with the vibrating pusher bar 4. This bar is rotated in the same clockwise direction around its pivot 35 as the vibration increases and is operated by any known suitable means of operation not shown for simplicity. The operation of the pusher bar 34 causes the carton represented by C1 to move so that the transversely arranged flight bar 13 engages with the rear face, and when the carton moves to the position indicated by C2, the next flight bar ( 13) move to engage the rear, and hold in place until the next flight bar 13 is moved behind the rear panel of the carton when the carton moves to the position marked C2. When arranged in this way, the carton C2 is actually positioned between a pair of flight bars 13 having a fixed interval so that they cannot escape therefrom and fully and absolutely adjust their position. During this type of operation, the end closure panels 53 and 61 pass under the pre-brake rotating elements 38 and 39, respectively, over the guide bars 36 and 37, so as to provide electrical components. Causes the locking tabs 57 to rotate from the plane of the panel 53, which tabs are then in a state for insertion into the holes 58 and also rotates the locking 64 from the plane of the panel 61. This locking tab is in a state for insertion into a hole (not shown) formed in the panel 63. This prebreaking action is facilitated by the radially elongated probes 40 and 41. The closing panels 53 and 61 are held in the upper position after the prebreaking action by the guides 71 and 71A fixed before the closing and locking operation.

Of course, the lateral movement of the carton, such as C2, is in engagement with the closed panel and the combined end structure with the plows 36 and 37 cooperating with the prebrake rotating elements 38 and 39. Is prevented.

In FIG. 2, a carton disposed at the C2 position of FIG. 7 is inserted between its front and rear flight bars 13, and the end closure panels such as (53) and (54) are adjusted to the closed position (94 And move to the right in co-engagement with a suitable plow, denoted by < RTI ID = 0.0 > and < / RTI > Closing panels 53 by appropriate means (not shown) for operating the flaps 59, 60 and 5 and flaps 65 and adjacent flaps 65 in a conventional structure and operation. ), (54), (61) and (63) immediately before closing. Once the end closure panel has been folded into the closed position, they are locked with rotary locking means 14 and 28 with locking fingers 15 and 29, where the fingers are like (57) and (64). Engage with the locks and place them into similar holes in the holes 58 and panel 63 to complete the packing operation as specifically described in US Patent Application No. 560,95, filed March 21, 1975. do.

From the above description, the unique main feeder arm and supplementary feeder arm having the structure according to the present invention tend to bend the slide type carton with the open end and bend downward in the hopper. It is apparent that having the unnecessary adhesion of the panel due to the glue wrap is solved by applying pressure to the carton by the supplementary feeder arm 81 and the parts joined thereto. In addition, the complete control of the blank is maintained by the unique cooperation of the feeding means, the pushers and the flight bar, and the effective continuation of the opening structure is initiated by the feeder arm and the fixed cam structure immediately before stripping of the carton by the stripper. It is evident that this ensures the loading operation under minimal disturbance at the rotational speed, in part due to the precisely coordinated coordination of the parts to increase the productivity of the parts, or vice versa, to reduce the rate of wear of the parts.
