2. Description of the Related Art

Most of the known packaging machines are dedicated machines configured to assemble only one size and one type of carton. Thus, in recent bottling plants, it is necessary to use multiple packaging machines when packaging various types of cartons. Each of these packaging machines takes up considerable floor space and is costly in terms of equipment and operation.

[0003] Some packaging machines use different sizes and different types of cartons, for example, cartons for packaging six, eight, or twelve packs in a rollable manner. Can be In such machines, switching from one size or type of carton to another size or type of carton always requires adjustment. In such an adjustment step, all cartons remaining in the packaging machine are manually removed and, if possible, mechanical adjustment of the machine components. During such switching, which can take up to 30 minutes or more, the machine cannot be used (known as "downtime"). This is a significant delay in bottling plants. Such delays may not only stop the packaging machine itself but also the downtime of the entire bottling line if a problem occurs during the switching step.

[0004] It is an object of the present invention to provide a packaging machine that can overcome the technical and operational deficiencies of known packaging machines.

The mechanism according to the invention is capable of assembling various types of cartons, such as, for example, roll-up cartons, completely closed cartons and basket-type cartons. Particular specifications for one type of carton include different sizes for that type of carton. For example, a mechanism according to the present invention can process fully closed cartons for eight or twelve articles.

1a and 1b, in particular in the drawings, the carton 10 is shown as a basket-type carrier, which in FIG. 1b is brought into a set-up state in which it can be lowered onto the article at any time. Is shown in the assembled state. The carton 10 has opposed side wall panels 12 and 14 and opposed end wall panels 16.

And a base panel 41, which are articulated with respect to the respective connecting panels. The upper panel 37 has three pairs of openings 4.
3, 45 are provided. The openings 43 and 45 are formed apart from each other between the side edges of the upper panel 37, and are configured to receive the upper portion of the article A as shown in FIG. 3B.

The carton should be changed according to the shape and quantity of the article to be packaged. Thus, the packaging machine according to the invention can be adjusted from many points of view so that it can handle different types of cartons. The main elements that are likely to be resized are the overall height "H" of the assembled carton and the overall length "L" of the carton when the base panel is closed, as shown in FIGS. 1a, 2a and 3b. is there. Here, the overall height “H” is equal to the distance between the upper edge of the side wall panel and the base panel.

FIGS. 4 to 7 show a packaging machine 50 for processing cartons, for example of the type outlined above. A double hopper 52 is provided at the upstream end of the packaging machine. The hopper 52 holds the basket type carton 10 and the completely closed type carton 30 in a flattened form in a processing waiting state.

The hopper unit 52 (FIGS. 6 and 7) comprises two (or more) individual hoppers 58, 60 arranged adjacent to each other. Each hopper 58,
60 is mounted on a frame 62 as shown in FIGS.
The frame 62 is mounted on a main shaft 64 rotatable around an axis XX. Each of the hoppers 58 and 60 is of a type that supplies by gravity. That is, the plurality of carton blanks are held in the respective hoppers in an inclined state so as to be able to perform forward feeding. It is understood that the hopper unit can comprise any number of hoppers configured to receive various types of cartons, and any number of hoppers arranged in a manner surrounding a rotary feeder described below. Will.

In this embodiment, a pneumatic cylinder (not shown) is used to drive the frame to rotate between two positions. Here, one of the two positions means that the first hopper 58 is set so that the completely closed type carton held in the first hopper 58 as shown in FIG. Is in the operating state
Position. FIG. 7 shows a second position of the frame 62, which is the other of the two positions. In the second position, the second hopper 60 containing the basket type carton is in the operating state.

[0074] The positions of the hoppers 58 and 60 are controlled by control means described later in detail.

As shown in FIGS. 6 and 7, when the first hopper 58 is set to the operating position,
The fully closed cartons are sequentially removed by a removal device, preferably in the form of a rotary vacuum-based feeder 66. The vacuum-based supply device 66 includes a set of suction cups 67 and 69, for example, a set of three suction cups. Each cup is connected to a drive shaft 70 via a drive rod 72.
Drive shaft 70 is supported at its ends by suitable conventional bearings 71, 73 mounted to side frames 84. For example, servo motor 75
Such a suitable driving mechanism is provided so that the driving shaft can be rotationally driven. The driving rod 72 is connected via a cam rod and a follower,
It is connected to the cam track. Thereby, when the drive shaft is rotationally driven, a uniform path to the suction cup is formed. By the path of the cam track, the suction cup can be extended toward the hopper,
The flattened carton can be taken out. Further thereafter, the suction cup and the carton can be rotated to the feed end of the packaging machine.

In order to shift the carton blank from the inclined state to the upright state, as shown in FIGS. 6 and 7, it is necessary to shift the rotation axis of the rotary feeder from a vertical plane.

By applying a vacuum to the pair of suction cups 67 and 69 when the pair of suction cups 67 and 69 abut the side wall 32 of the carton 30, the hopper 5
The carton can be removed from 8,60. A vacuum is maintained while the carton is rotated into position. When the predetermined position is reached, the carton 30 is released from the supply device 66 by the vacuum circuit breaker interrupting the vacuum transmission.

If it is desired to package in a different type of carton, for example, if it is desired to package in a basket type carton 10 held in a second hopper, Make some adjustments to the printing machine. First, as described above, the second hopper 60 is moved to the operating position. Since the relative position of the second hopper with respect to the rotary feeder 66 is different from that of the first hopper 58, it is necessary to move the "sucking" points of the suction cups 67, 69, and the vacuum The "on" and "off" positions of the force transmission need to be changed. These changes require moving the cam track and / or moving the vacuum transfer control cam to the second position. The servomotor 167 shown in FIG. 8 controlled by the control system moves these subassemblies between two positions.

Preferably, it has a third position for vacuum transmission. This third position is an "initial setting" position where vacuum transmission is stopped with respect to rotation of the suction cup.
The "default" position can be employed when replacing a carton or when an error occurs in the packaging machine.

FIG. 8 shows an unloading device configured to be able to pull out the lowermost flat carton from the hopper unit. As mentioned above, a preferred dispensing device is in the form of a vacuum dispenser 66 having suction cups 67, 69 supported on cup holders 74, 76, respectively. The cup holders 74, 76 are preferably fixedly attached to each of the long support rods 78. Long support rod 7
8 are slidably mounted on each of the collar structures 80. The collar structure 80 itself is rigidly attached to the rotatable main shaft 70. The cup holders 74 and 76 are mounted on a cam rod 79 that extends into a side frame 84 that houses a cam track described below. FIG.
As shown in FIG. 3, three sets of carton unloading devices are mounted on a rotatable main shaft 70.
It is provided in connection with. Since all three of the take-out devices have the same configuration and operate in the same manner, only one of the three sets will be described in detail.

FIG. 9 is an exploded perspective view showing a rotary vacuum type feeder. Side frame 8
A fixed cam plate 82 is mounted on the inner surface of the fourth cam plate 4. An opening 86 is formed in the side frame 84, and the drive shaft 7 is inserted through the opening 86.
0 extends. A cam track 88 is formed on the fixed cam plate 82. A cam follower (not shown) is arranged in the cam track 88. The purpose of the cam track 88 is to move the cam rod 79 away from the main shaft 70.
Is easy to extend, and easy to contact with the carton. Thereby, one carton can be taken out from the hopper 58 and the carton can be rotated along a uniform path toward the paper supply chain 100 described later. When rotating the carton from the hopper, a back support feeder is used to separate the opposing side wall panels to assist in the uprighting of the carton.

The supply mechanism 66 is provided with a plurality of vacuum circuit breakers. The vacuum circuit breaker is used in connection with a vacuum transmitter, so that a vacuum transmission point and a vacuum interruption point can be set.

[0083] The process of supplying the carton from the hopper to the paper supply chain will be described.
The main shaft connects the ejection device 66 with the arrow “Z” in FIGS. 10 and 11.
In the direction indicated by "". The suction cups 67 and 69 move to a position where they come into contact with the side wall 32 of the carton 30 by rotating the removal device. And
When the cup abuts the side wall 32 of the carton 30, vacuum is applied to the set of suction cups. This will take out the carton and then
The paper is conveyed to the paper supply chain 100. During this transfer, a vacuum is maintained so that the suction cup can hold the carton wall. When the carton is placed on the paper supply chain, the vacuum circuit breaker shuts off the vacuum transfer to the suction cup, thereby releasing the carton. In this way, the operating speed of the device system is improved, and the efficiency and durability are also improved.

As can be seen from FIG. 12, the carton has started to move from a flat state and is in an assembled state at the paper supply chain 100. As a matter of course,
The final assembly operation is partially based on the logistics feeder (or carton opening means)
90.

Referring to the configuration of the logistics support feeder 90, as shown in FIGS. 10-13, the logistics support feeder 90 may be adapted to engage one or more walls of a carton. An engaging means is provided. In this embodiment, the engagement means has a suction cup 92 supported on a cup holder 94 installed on a slide member 96. Suitable means are provided for moving the engagement means in the "X" and "Y" directions. For example, the slide member 96 is mounted on a lateral carriage 98 and can move in the X direction. Lateral carriage 98
Preferably have guide rails 9 fixed to a support frame (not shown)
9. Here, the horizontal carriage is configured to move the suction cup and the slide member in the Y direction. Therefore, the suction cup 9
2 can move in the direction of contact and detachment with respect to the rotary vacuum type supply device 66,
It can move in a direction perpendicular to the turning trajectory Z of the carton. If necessary, a movement range limiting member (limit stop) can be provided at the end of the slide member or the guide rail.

It will be appreciated that other elements and configurations may be used to enable the assembly to move in the XY directions.

The slide member 96 is driven by a suitable driving means. For example, it is driven by a first linear servomotor (not shown) controlled by a suitable control system. The horizontal carriage 98 is driven by the second driving means. For example, it is driven by a second linear servomotor (not shown) controlled by the above control system. Therefore, the position of the suction cup 92 of the rear support supply device can be moved to any desired position. In some embodiments, the control system is programmed to preset to the appropriate XY coordinates and to define the path of the suction cup. Further details of the control system will be described later.

In use, the logistics feeder 90 pulls the one or more walls 34 of the carton away from the opposing walls 32 held by the rotary feeder 66. In this embodiment, the opposing walls used are the side walls 32,34. When the rotary feeder 66 conveys the carton, the suction cup 92 of the rear support feeder 90 moves to the front side as shown in FIG. Contact. Preferably, the abutment point is the central part of the wall to be separated. By applying a vacuum force to the suction cup 92, the side wall 34 is held. When the rotary feeder 66 continues to rotate the carton forward, the suction cup 92 of the rear support feeder moves away from the rotary feeder 66, as shown in FIG. The side walls 32, 34 are separated from each other.

In this embodiment, the front suction cups 67, 69 of the rotary feeder release the front end panel 46. This assembles the carton into a partially upright state in which the side and end walls are substantially trapezoidal. Thereafter, the vacuum transmission to the logistics support feeder is cut off. This releases the carton from the logistics supply, as shown in FIG.

Although it is preferred to use a suction cup to hold one or more walls, in some embodiments other components can be used, for example, using mechanical coupling means Can be.

As described above, the preferred “sucking” position of the suction cup 92 of the rear support feeder is:
It is approximately the center of the side wall panel of the carton. This position depends on the type of carton. In particular, it varies with the dimensional changes of the side walls and end walls in each carton type and with the dimensional changes of the side walls and end walls in various carton sizes. Similarly, the path of the suction cup separating the two walls will vary depending on the particular carton type to be erected. The suction cup may follow a vibration path similar to that disclosed in WO 92/15450. Alternatively, a rotating path can be used for some cartons. An advantage of a logistics feeder is the flexibility provided by the system. In particular, the back support feeder can move the suction cup 92 to any position, and can use any path within the limited movement range of the slide member 96 and the lateral carriage 98. FIGS. 14 and 15 show an example of a route, and velocity components and acceleration components of the “X” direction and “Y” direction driving means.

By programming the control system in advance, the position and path of the suction cup 92 can be set. Thereby, the stop time at the time of switching the carton type or style is reduced. According to the present invention, the operation speed of the device system is increased, and the efficiency and durability are also increased.

The carton 30 moves on the track path and reaches the paper supply chain 100. In particular, the front end 102 of the carton 30 abuts against the front lug 104 of the paper supply chain 100. The front lug 104 connects the front end 102 to the rotary feeder 66.
The suction cups 67 and 69 are separated from each other. As a result, the front end panel 46 and the side wall panel 34 are arranged in a substantially vertical positional relationship. at the same time,
The rear lug 106 moves and abuts against the rear end panel. This assists in completing the assembly. Thereafter, the suction cups 67 and 69 of the rotary feeder 66 release the carton 30 and move further in the “Z” direction. The paper supply chain 100
Move the carton 30 downstream and place the carton at the introduction station.

Next, the configuration of the paper supply chain 100 will be described with reference to FIGS. The paper supply chain 100 includes an upper side lug chain 108 and a lower side lug chain 110. Both side lug chains have the same configuration as each other, and are endless chains having a plurality of front lugs 104 and a plurality of rear lugs 106. The upper chain 108 has a front lug 104 and the lower chain 110 has a rear lug 106. Each chain is driven forward by driving means. For example, it is driven forward by one or more servomotors controlled by a control system.

To change the machine settings from one type of carton to another, it is necessary to change the distance D between the front and rear lugs. Therefore, at the time of switching, the servomotor controlling the lower chain is driven by the front lug 104.
The relative position of the rear lug 106 with respect to
Move. For example, the sidewall of a basket-type carton is shorter than the sidewall of a fully closed carton. Therefore, when switching the carton type from the completely closed type carton to the basket type carton, the interval D is narrowed. In the reverse switching, the interval D is increased. In this embodiment, the spacing between the front and rear lugs is increased or decreased by 10 cm.

The relative movement of the rear lug 106 changes the position at which the rear lug 106 abuts the rear panel of the carton. The rear lug 106 needs to abut against the rear panel while rotating. When the rear lug 106 moves forward, the contact point also moves forward. In order to maintain the contact point at an appropriate position, it is necessary to move the paper supply chain 100 backward by a corresponding distance (for example, 10 cm). Those skilled in the art will appreciate that when the rear lug 106 moves away from the front lug to increase the spacing D, the paper supply chain must be moved forward a corresponding distance. The movement of the paper supply chain 100 is achieved by using a pneumatic cylinder (not shown).

The upright carton is driven forward by the carton 100 and is held in place by a horizontal plate (not shown) and placed on the carton lowering module 111. The carton base panel 46 is folded outward by guides 114 located on both sides of the carton.

Once the carton has been assembled, the carton is transported to the introduction station 120. Here, as the carton is disengaged from the paper supply chain 100 and the carton is transported downstream, the carton gradually engages with the carton lowering module 11 as shown in FIGS. Move to.

The carton lowering module has a conveyor. For example, the table 113
It has a pair of side lug chains 112 mounted thereon. The side lug chain 112 is inclined downward toward the loading point 114. Each side lug chain 112 has the same configuration as each other, and is an endless chain 115 driven by a motor such as a servomotor. Appropriate carton engaging means for engaging with the carton supplied from the paper supply chain at predetermined intervals is connected to the side lug chain. In this embodiment, the carton engaging means comprises a plurality of guide pin lugs 116 mounted on an endless chain. Guide pin lugs 116 engage the opposing base panels 24, 26 of the carton and assemble the base panels 24, 26, the side panels 12, 14 and the end panels 16, 18 as the carton moves downstream. It functions to keep it in a state.

Each lug 116 is preferably substantially wedge-shaped and includes a support surface 117 disposed at an acute angle to the conceptual vertical plane. A plurality of pins, that is, four pins 118, are attached at predetermined intervals along the support surface 117. Each pin 118 is disposed on a support surface 117 such that in use, the pins can be received in corresponding openings in the base panel. In this embodiment, only the front three of the four pins are required for a basket type carton. Of course, for larger cartons, such as fully closed type cartons, all pins are used. Conversely, for smaller cartons, only two pins need be engaged.

The endless chain is driven by a motor such as a servo motor. As each lug 64 moves along the path made by the cam track (not shown), the carton 10 is lowered by the endless chain 113 toward the introduction station 120 while being maintained in a horizontal position by the lugs 116. .

It is also conceivable to use the descent module to introduce various arranged articles into the carton, for example two or three rows. Thus, one or both of the pairs of chains, and the table, are pneumatic cylinders (not shown).

Articles, such as bottles 122, are fed into the packaging machine by an end feed conveyor 124. The bottle line pressure is controlled by the well-known feeding star wheel 126.
(FIG. 16). The articles are separated by a series of article grippers 128
Each carton 30 is divided into an appropriate number of groups. The article gripper 128 controls the flow rate of the articles so that the bottle is introduced into the carton at the same speed as the flow rate of the carton.

Next, the configuration of the article gripping assemblies 128 arranged on both sides of the article conveyor will be described. Multiple pairs were provided on individual endless chains,
Four blocks or spacer members 131 are attached. Each block has four semicircular recesses 133 located adjacent to each other and configured to receive a portion of a bottle or can. The endless chain is mounted on a table. One or both of the gripping assemblies can be moved toward and away from the article conveyor depending on whether two rows of articles or three rows of articles are required. In this embodiment, when two rows of articles are requested, one gripping assembly moves toward the second gripping assembly. Thus, each gripping assembly is configured to grip a portion of the articles forming the outer row, as shown in FIG. The spacing between the supply star wheels will be reduced when it is desired to distribute the articles in two rows, and accordingly, when it is desired to distribute the articles in three rows. Will move. In the case of a carton suitable for six articles arranged in two columns by three rows, the leading receiving part of each gripper is left empty.

In the case of a carton suitable for three rows of articles, the central row of articles moves forward in the arrangement shown in FIG. In this way, an appropriate number of articles is selected.

The article is gradually released from contact with the gripper assembly and is transported by the article conveyor to the entry station.

In the introduction station 120 shown in FIG. 4, articles forming a group are introduced into a carton, and both the carton and the article group move forward. Carton
Based on the downward tilt of the endless chain on the carton drop module described above, it is lowered onto the article. As shown in FIG. 3, the lateral movement of the carton at the loading station is controlled by a pair of guides located above each chain and configured to receive the free end of each base panel. The vertical movement of the carton
It is controlled by a pressure belt positioned above the endless chain and configured to apply a downward pressure to the handle structure or optionally to the top panel. In some embodiments, instead of a pressure belt, a fixed guide can be used, or, where appropriate, a combination of a vertically arranged endless chain and lugs as commonly used, Will be appreciated.

As the articles are introduced into the carton, they are conveyed by the article conveyor and / or pressure belt towards a further endless chain with side lugs 210. By using this further endless chain, the carton is transported to the output end of the packaging machine. At this stage, both base panels are folded down to the underside of the carton by using suitable folding means such as, for example, fixed guides (not shown). The folded base panels are interconnected by a conventionally known locking mechanism. In order to prevent inadvertent (unintended, undesired) upward movement of the carrier, the second pressure belt 2

At the introduction station 204, the lower part of the carton is inserted into the openings 43, 45 by lowering the carton. In this embodiment, the process is provided by a first pressure belt 206 located in the central region. First
The pressure belt 206 lowers the top panel, allowing the neck of the article to pass through the opening. In this embodiment, the first pressure belt is mounted on a hydraulic platform 208 that can be raised and lowered according to the carton type. By using appropriate control means, the height position of the platform is controlled.

As the carton is moved downstream by the side lug chains 210, the side wall panels 35 are folded into a position substantially perpendicular to the top panel 39 by a fixed guide (not shown). The partially upright carton is thus transported to the second set of endless chains. The endless chain transports the carton to the output end of the packaging machine. In this embodiment, a second pressure belt 2 provided to minimize movement of the top panel or handle structure
12 can be moved up and down with respect to the carton as needed. Similarly,
The set of endless chains 210 is separated or approached by a horizontal adjustment controlled and driven by a servomotor (not shown). The base is a known means 214
And, if necessary, the article holding panel is formed by known means 216. When the carton is fixed, the packaging operation is completed.
