Abstract

When bags (5a,5b) of a two-connected bag (5) are filled with a filler by a packing processing device and then the two-connected bag (5) is separated from a hole (11) to make the two bags (5a, 5b) independent, the present invention is capable of exactly separating the filler without damage to the filler. Each of the bags (5a,5b) of the two-connected bag (5) after filled is pinched by a pair of chucks (33, 33). Side grippers (13, 13) and a central gripper (14) are opened and then a gap between the chucks (33, 33) is widened in a widthwise direction of the two-connected bag (5). Therefore, each of the bags (5a, 5b) is pulled in the widthwise direction of the bag to separate the hole (11). The separation of the hole (11) is performed when the two-connected bag (5) is transferred to a predetermined position by the chucks (33, 33).

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bagging packing method and apparatus using two consecutive bags,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bagging method and a bagging method using two consecutive bags each having two bags successively connected in a horizontal manner and having a vertically separated portion (so-called perforation, etc.) formed in a central sealing portion The present invention relates to a bagging packaging method and apparatus, and more particularly, to a bagging packing method and apparatus in which each bag of two consecutive bags is separated and sent to a predetermined position after bagging packing (the bag is referred to as a bag, Of course, this concept includes a bag, a bag, etc., and they may be used in combination.)

Patent Document 1 discloses a bagging and packaging method and apparatus using two consecutive bags. In the patent document 1, the two consecutive bags sandwich the sealing portions on both sides by a pair of side grippers (side grippers) and sandwich the center sealing portions by the center grippers. The two consecutive bags hanging from the gripper are intermittently conveyed along the circular conveying path and are simultaneously conveyed to the two bags constituting the two consecutive bags in the course of the conveyance, Filling of the object to be filled (packing object), sealing of the bag inlet, and the like are successively carried out. After the sealing, two bags are continuously connected and discharged as two consecutive bag products, And then sent to the next process (such as packaging).

Such a bagging packing method using two consecutive bags is advantageous in that a yield of twice as much as that in the case of using a usual bag (a bag having one accommodating chamber) is obtained. Also, it is preferable that the bagging packing machine for packing two consecutive bags has a pair of side grippers and a central gripper. For example, a double-type bagging packing machine (double bag packing machine shown in Patent Document 2 The number of grippers provided on the packing machine can be reduced compared to the case where the pair of side grippers are provided for two independent bags such as a bugging packing machine for carrying out various packaging processes, Compacting can be achieved.

In Patent Document 1, two consecutive bag products are discharged while two bags are continuously connected from a bagging packing machine. These two consecutive bag products may be shipped as they are, but two bags of two consecutive bag products are required to be separated from the central sealing portion (pre-separation portion .

Patent Document 3 discloses a separating device in which two consecutive bag products discharged from a bagging packing machine are separated from the separating portion (perforation) into two independent product bags.

In the separation device described in Patent Document 3, two consecutive bag products packed by a separate bagging packing machine are transported in the bag width direction by a belt conveyor, and two bags (two bags) A bag of a rear portion and a rear portion of a bag) are inserted into a roller from above and below, respectively, and the rotational speed of the roller in which the front bag is inserted is increased, It is separated into two independent product bags.

: Japanese Utility Model Publication No. 62-115312 : Japanese Patent Application Laid-Open No. 2004-244085 : Japanese Patent No. 455048

According to the separating device of Patent Document 3, since the two consecutive bag products are strongly inserted in the up and down directions by the rollers, there is a fear that the charged material is broken by the rollers. In addition, when two consecutive bags are inclined on the belt conveyor and the separating portion (perforation) is not perpendicular to the conveying direction, separation at the separating portion may become unstable.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art, and it is an object of the present invention to provide a method for separating two consecutive bags after filling a filler into two independent bags, .

The bagging and packaging method according to the present invention is a bagging and packing method in which two bags are successively connected in a row in a horizontal direction and the sealing portions on both sides of two consecutive bags formed with vertical separating portions in the central sealing portion are sandwiched by a pair of side grippers, The sealing portion is pinched by the center gripper and conveyed along a horizontal conveyance path, and in the course of the conveyance, the two bags of the two consecutive bags are sequentially subjected to the packaging treatment including filling of the opening of the bag inlet and the filling material , And then, when the two consecutive bags after filling are discharged from the conveyance path or transferred to a predetermined position out of the conveyance path, after the filling of the filling material, (For example, in the widthwise direction of the bag) It characterized in that the separation step of separating portions formed. In addition, the separating portion is a portion where cut lines are continuously and intermittently formed, for example, in a dashed or dashed line so that two consecutive bags can be easily separated at the same site. Typically, the cut line is a dashed line Called so-called perforations. The transport path may be circular, straight, racetrack, or the like. There may be intermittent transfer (see Patent Documents 1 and 2) and continuous transfer (refer to Japanese Patent Application Laid-Open No. 2001-72004) as a transfer method of the two consecutive bags .

Preferably, the separation step is performed on the conveying path (preferably, in the case of intermittent conveying, when the two consecutive sheets are stopped at a predetermined stop position on the conveyance path) After the side grippers and the center grippers are opened, the separating portions are separated by pulling each bag of the two consecutive bags in opposite directions by the pair of chucks . In this case, it is preferable that the interval of the pair of chucks is widened in the width direction of the bag of the two consecutive bags so that each bag of the two consecutive bags is pulled in the bag width direction. The operation of widening the interval between the pair of chucks in the width direction of the bag of the two consecutive bags is performed when the chuck serves to transfer the two consecutive bags from the conveying path to the predetermined position, . It is preferable that a portion held by the pair of chucks is the upper end of each bag of the two consecutive bags.

In the bagging and packaging method, in the case where the packaging process includes a sealing process of the bag inlet, the separation process is performed after the sealing process. In this case, preferably, on the conveying path (preferably in the case of intermittent conveyance, when the two consecutive sheets are stopped at a predetermined stop position on the conveyance path), each of the two consecutive sheets And is sandwiched by the pair of chucks. The operation of widening the interval between the pair of chucks is preferably performed in the process of transferring the two consecutive bags to the predetermined position by the chuck. However, each bag (product bag) of the two consecutive bags sealed in the bag inlet is not transported to the predetermined position but the separating process is carried out on the conveying path, the chuck is opened immediately after the separating process to open each bag, Or may be discharged from the transfer path.

In the bagging and packaging method, in the case where the sealing process of the bag inlet is not included in the packaging process, the two consecutive bags conveyed by the pair of chucks are conveyed in the next step (for example, It is preferable to carry it to the gripper of the processing step. At this time, it is preferable that the chuck is moved in the process of transferring the two consecutive bags to the predetermined position. In the case of sealing the bag inlet in the present invention, the sealing so-called " airtight seal " for leaving a vent path in the bag and the bag (see, for example, Japanese Patent Application Laid-Open No. 2000-142622 ) Are not included.

Further, the separation step may be carried out in a process of transferring the two consecutive bags along the conveyance path (in the case of intermittent conveyance, while the conveyance path is stopped or during actual conveyance). In this case, the center gripper is opened, and then the gap between the pair of side grippers is widened to pull each bag of the two consecutive bags in the bag width direction, thereby separating the separating portion. In the case where this method is carried out, it is preferable that the sealing process of the bag inlet is included in the packaging process so that the separation process is performed after the sealing process. When the side gripper is opened after the separation process, each bag (product bag) Is released from the side gripper and released from the transport path.

In the bagging and packaging method, a preliminary separation step may be performed to separate a part of the separation part (preferably, a range from the lower end of the two continuous bags to a predetermined distance above) before the separation step. In the case of intermittent feeding, this preliminary separation step is preferably performed when the two consecutive bags are stopped on the feeding path. Two specific means for carrying out this preliminary separation step are mentioned.

The first means is to pull apart each bag of the two consecutive bags sandwiched by the side grippers and the center gripper in the bag width direction to separate a part of the separating portion. This preliminary separation step is preferably carried out before each of the bags of the two consecutive bags is filled with the filling material.

The second means is characterized in that each bag of the two consecutive bags sandwiched by the side grippers and the center gripper is inserted into a pair of pressure plates and a convex bar formed on one side of the pressure plate is press- . This preliminary separation step is preferably carried out after each bag of the two consecutive bags is filled with the filling material.

In either of the preliminary separation steps, the center gripper is sandwiched by the central sealing portion, so that the separation portion of the region near the upper end in which the center gripper is sandwiched is not separated.

The bagging and packaging apparatus according to the present invention is for carrying out the bagging packing method (a method of using a pair of chucks in the separating step), in which two bags are successively connected in a row in a horizontal direction, A pair of side grippers for holding sealing portions on both sides of the two consecutive bags formed with the separating portions and a plurality of tanks of a central gripper for holding the central sealing portion and the side grippers and the center gripper are arranged along a horizontal movement path Intermittently moved to suspend the two consecutive bags and intermittently conveyed along a horizontal conveyance path, and at each stop position on the conveyance path, with respect to two bags of the two consecutive bags, Filling process is sequentially carried out, and then, after the filling process Group of two consecutive bag is released from the conveying path or from the outside conveyance path is conveyed to a predetermined position. In this bagging and packaging apparatus, a separating device for separating the separating portions of the two consecutive bags is disposed in the vicinity of the stop position on the downstream side of the stopping position where the filling process is performed on the conveying path, Respectively. The pair of chucks sandwiching each bag of the two consecutive bags when the two consecutive bags are stopped at the stop position where the separating device is disposed, and after the side gripper and the center gripper are opened, the movement of the pair of chucks Each bag of the two consecutive bags is pulled in opposite directions (for example, in the bag width direction) to separate the separating portions.

In the separating apparatus, it is preferable that the pair of chucks can be widened or narrowed. In this case, the interval between the pair of chucks may be widened in the width direction of the two consecutive bags, and each bag of the two consecutive bags may be pulled in the bag width direction to separate the separating portion.

The gap between the pair of chucks may be widened at a position where the pair of chucks hold each bag of the two consecutive bags (a stop position on the conveying path). However, the pair of chucks move between a nipping position in which each bag of the two consecutive bags is sandwiched and an open position in which each bag of the two consecutive bags is opened so that the two consecutive bags are conveyed It is preferable that the distance between the pair of chucks can be widened in the process of moving the pair of chucks from the nipping position to the opening position.

In the bagging and packaging apparatus, when the packaging process includes the sealing step of the bag inlet, the separating device is disposed in the vicinity of the stop position on the downstream side of the stop position where the sealing process is performed.

In the bagging and packaging apparatus, when the sealing process of the bag inlet is not included in the packaging process, the two consecutive bags are transferred to the predetermined position by the pair of chucks, and the next process For example, a vacuum processing step).

In the bagging and packaging apparatus, a part of the separating part of the two consecutive bags (preferably, a part extending from the lower end of the two consecutive bags up to a predetermined distance in the vicinity of the stop position on the upstream side of the stop position in which the separating device is arranged ) Can be disposed in the pre-separation device. As this preliminary separation device, two types are specifically mentioned.

The preliminary separator of the first type (corresponding to the first means) comprises first and second nip members which sandwich the respective bags of the two consecutive bags on both sides thereof and enlarge or narrow the distance between them, The first and second nipping members extend a distance between the first and second nipping members after separating each bag of the two consecutive bags to separate a part of the separating portion of the two consecutive bags. It is preferable that this type of preliminary separation device is installed at a stop position on the upstream side of the stop position where the filling process is performed.

The preliminary separation device includes, for example, a pair of advancing / retreating blocks disposed on both sides of the conveying path and advancing or retreating against each other in a horizontal plane, and the forward end of each advancing / A pair of plate springs provided on one of the forward and backward blocks and a pair of leaf springs provided on the other forward and backward blocks are disposed symmetrically with respect to the conveying path with the pair of leaf springs extending obliquely toward the downstream side, And each sandwiching portion of the first and second sandwiching members is provided at the tip of each of the plate springs. In the present invention, the numerical values, the shapes, the positions, and the like described in the specification, the claims, and the drawings not only refer to the numerical values, the shapes, the positions, etc. physically and accurately, And is intended to include all such numerical values, shapes, positions, and the like, including approximate ranges of values that can be reasonably expected and those which may occur. That is, the upper and lower limits are design specifications that can be appropriately changed depending on the environment at a level of a person skilled in the art. For example, " arranged symmetrically with respect to the conveying path " includes " arranged substantially symmetrically with respect to the conveying path ". Hereinafter, the same is true in the present specification. &Quot;

The preliminary separation device of the second type (corresponding to the second means) is arranged on both sides of the conveyance path, and advances or retracts in the horizontal plane against each other, and when each of the two consecutive sacks is inserted And each of the pressure plates has a pair of pressing portions for pressing each bag of the two consecutive bags, and a vertical convex bar is formed between a pair of pressing portions of the one pressing plate, The convex bar is pushed along the separating part at the same time when the pair of pressure plates advances and each bag of the two consecutive bags is pressed on both sides so that a part of the separating part is separated. It is preferable that this type of preliminary separation device is installed at a stop position on the downstream side of the stop position where the filling process is performed. In either of the preliminary separating apparatuses, when the preliminary separation is performed, since the center gripper is sandwiched by the central sealing portion, the separation portion of the region near the upper end where the center gripper is held is not separated.

Wherein the separating device used in the bagging and packaging apparatus comprises a pair of chucks for holding each bag of the two consecutive bags in a suspended state and widening or narrowing the interval between the two bags, The pair of chucks sandwiching the respective bags of the two consecutive bags are moved in a reciprocating manner between a nipping position for holding each bag of the continuous bag and an open position for opening each bag of the two consecutive bags, The two consecutive bags are transferred to a predetermined position in the course of moving from the nipping position to the open position, and the interval between the pair of chucks is widened to separate the separating portions of the two consecutive bags.

According to the packaging treatment method and apparatus of the present invention, when the two consecutive bags after filling the filling material are separated from each other by the separating portion to form two independent bags, the filling material can be surely separated without damaging it.

When a pair of chucks for holding the upper end of each bag of two consecutive bags and moving reciprocatingly between the nipping position and the open position are used and the two consecutive bags after the filling are transferred from the conveying path to a predetermined position The pair of chucks are separated from each other by separating the separating portions of the two consecutive bags in the course of the conveying so as to prevent interference between the pair of chucks and the gripper of the bagging and packaging machine, The separation unit of the two consecutive bags can be separated.

The separating device includes a holding position for holding the bags 5a and 5b of the two continuous bags 5 stopped at the stop position 7 and an opening position for holding the bags 5a and 5b And a pair of right and left chucks 33 and 33 (see FIG. As shown in Figs. 6 and 7, the chucks 33 and 33 are moved in the direction from the nipping position toward the open position, while the chucks 33 and 33 move backward from the open position toward the nipping position In the process, we narrow the gap (returning to the original interval). In this example, both of the chucks 33 and 33 are symmetrically moved in the bag width direction when the pair of chucks 33 and 33 are widened or narrowed. However, good. The separation device includes a driving source (for example, an air cylinder) and chucks 33 and 33 (not shown) for moving the chucks 33 and 33 from the nipping position toward the open position, (For example, an air cylinder) which is not shown in the drawing.

The side grippers 13 and 13 of the bagging and packaging machine 1 and the center gripper 14 are moved from the center gripper 14 to the back side of the two successive bags 5 by the chucks 33 and 33 A step of receiving the continuous bag 5 and delivering the bags 5a and 5b to the gripper of the vacuum processing apparatus 2) will be described in more detail.

The two consecutive bags 5 are held by the side grippers 13 and 13 and the center gripper 14 and are transported along the transport path 21 toward the stop position 7 as shown in Fig. And the chucks 33 and 33 are standing at the nipping position in the open state. When the chucks 33 and 33 are opened, the holding pieces 33a and 33a of the chucks 33 are opened so as to escape to both sides of the conveying path 21, And does not interfere with the continuous bag (5).

When the two consecutive bags 5 are stopped at the stop position 7, the chucks 33 and 33 are closed as shown in Fig. 5 (b) so that the upper ends of the bags 5a and 5b of the two consecutive bags 5 Hold. In this gripping position, the chucks 33 and 33 are disposed between the side grippers 13 and 13 and the center gripper 14, respectively, and do not interfere with each other.

The side grippers 13 and 13 and the center gripper 14 are opened as shown in Fig. 5 (c) after the chucks 33 and 33 sandwich the bags 5a and 5b of the two consecutive bags 5, The two consecutive bags 5 are transferred to a predetermined position away from the conveying path 21 in a state of being held by the chucks 33 and 33 while being held by the chucks 33 and 33, Go to another transport path). [0034] When considering the conveyance of two consecutive bags 5, the separating device may be referred to as a conveying device having a separating function.

The process in which the chucks 33 and 33 are moved from the nipping position to the open position (the process in which the two consecutive bags 5 are transferred from the conveying path 21 to the predetermined position) will be described with reference to Figs. 6 and 7 Explain.

In Figs. 6 (a) and 7 (a), the chucks 33 and 33 sandwich the bags 5a and 5b of the two consecutive bags 5 at the nipping positions. At this time, the interval between the chucks 33 and 33 is D0. When the chucks 33 and 33 start to move from this nipping position (the moving direction is the normal direction (normal direction) of the conveying path 21) , The spacing between the chucks 33 and 33 starts to increase. The bags 5a and 5b of the two consecutive bags 5 are pulled toward the outside in the bag width direction so that the perforations 11 of the central sealing portion 8 are separated and the two consecutive bags 5 are separated from each other And separated into individual bags 5a and 5b (see Figs. 6 (b) and 7 (c)). At this time, the interval between the chucks 33 and 33 is D1 (> D0). The perforations 11 are separated from each other in the stop position 3 in advance so that the perforations 11 can be separated from each other even if the chucks 33 and 33 are not widened too widely It is surely done. The two-dot chain line 34 shown in Fig. 7 represents the movement locus of the perforation 11.

When the chucks 33 and 33 move in the normal direction of the conveyance path 21 and reach the open position (see Figs. 6 (c) and 7 (d)), the bags 5a and 5b And reaches the predetermined position (in this example, the chamber body of the vacuum processing apparatus described later). Subsequently, a gripper 35 installed in the chamber main body horizontally sandwiches a somewhat lower portion of the chuck 33, 33.
