[Technical field to which the invention belongs]

 The present invention relates to a cutting and feeding device for feeding cut articles cut by a cutter unit, for example, sachets cut from a serially packed pouch into a fixed position on a packaging conveyor or the like. The present invention relates to a device for forcibly ejecting cut articles that can be smoothly fed in the transporting section up to the point.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a continuous package sachet cutting and feeding device (also referred to as a pouch dispenser) is a device that cuts a three- or four-side seal sachet (pouch) prepared in a continuous package one by one at a fixed size and correctly feeds the product into a fixed position. is there. For example, cut pouches are put into a fixed position of the articles on a plurality of items flowing on the packaging conveyor line, and then used for a pillow packaging conveyor line (horizontal pillow, vertical pillow) for packaging.

[0003] As a method for discharging the cut pouches from the cutting section and putting them out of the apparatus in the above-mentioned continuous pouch cutting and feeding apparatus, as shown in FIG. A U-shaped shoot method is known. In this natural dropping method, the continuous pouches b are cut into the respective pouches d by cutters (cutter blades) a and a ', and the pouches d are dropped on a chute c and slid to be guided downward. A guide f prevents the chute c from falling off when it falls.

[0004]

[Problems to be solved by the invention]

 However, in the above-mentioned natural fall method, there is a problem that the following charging abnormality occurs. "Insertion error due to sticking of small bags due to glue sticking to cutter blade". In order to use a series of continuous pouches and the next continuous pouch successively in the cutting and feeding device, as shown in FIG. 4, the tail b1 of the previous continuous pouch and the head b2 of the subsequent continuous pouch are connected. They are connected with adhesive tape g. When the joint portion of the tape is cut by a cutter, an adhesive glue residue of the tape (indicated by e) may adhere to the cutting edge. When the cutting is repeated and the amount of glue residue e attached to the cutter blade becomes large, the cut pouch d comes to adhere to the cutter blade as shown in FIG. "Abnormal loading due to avalanche of small bags caused by impact of cutter cutting when chute falls." The cut pouch d does not fall normally and uses the natural fall due to its own weight as described above. Missing trouble occurs. That is, it falls into the injection device via the chute c. At this time, the pouch d after cutting, which is as light as several g, may be inclined due to the impact of the cutting without the center direction of the pouch falling along the vertical direction. On the other hand, the width of the chute is about a few mm wider than the width of the pouch so that the chute can be introduced so as not to be caught or clogged at the entrance. For this reason, as shown in FIG. 6, when the pouch falls down in an inclined state, the diagonal corners of the pouch may be caught on the side wall of the chute and clogged. As described above, this phenomenon also causes a shift in the injection timing and a problem of missing the input tooth. “Anomaly of sticking to the chute due to electrostatic charging of the sachet”. In the process of transporting the continuous pouches b to the cutters a and a ', static electricity may be charged to the pouches due to sliding contact between the pouches and the transport guide portion. When such an electrostatically charged pouch is cut, the pouch does not fall spontaneously but is attracted to the chute c or the guide f by electrostatic force and sticks. In particular, when the weight of the pouch is as small as several g, as shown in FIG. 7, the above-mentioned catching force exceeds the force of the natural fall, and the pouch does not fall normally, causing a shift in the charging timing and a missing tooth. Trouble occurs.

As a countermeasure against the static electricity, a method using a chute made of an antistatic resin or a static eliminator h as shown in FIG. 8 is conventionally known. However, these methods still have problems to be solved. In other words, a chute made of antistatic resin suppresses the generation of static electricity when sliding on the chute surface, but has no effect on already charged pouches. In addition, the effect of the static eliminator is not stable because the area where the static eliminator is installed is narrow and it is difficult to install the static eliminator at the position where the static electricity in the small bag is sufficiently removed.

Further, as described above, the width of the side wall of the chute having a U-shaped cross section is determined according to the width of the pouch. Therefore, when cutting several types of sachets with the same feeding device, the chute must be manufactured for each sachet, and the shoot must be changed and adjusted at the time of production changeover, and the time for switching models is reduced. Had occurred.

[0007]

[Problems to be solved by the invention]

 In the conventional continuous pouch cutting and feeding device, in the chute method that utilizes the natural fall of the pouch due to its own weight, a fault in the shooting (such as a shift in the feeding timing in the chute or a drop in the feeding tooth, such as a problem with the cutter blade). When a malfunction occurs due to sticking of small bags due to glue sticking on the bag, abnormal loading due to abrasion of the small bag caused by the impact of the cutter when the chute falls, or abnormal loading due to static charge of the small bag, the work that should be inserted If not, the product becomes defective and not only needs to be manually refilled, but also shuts off the continuous bagging / cutting / cutting device itself, so that the abnormality (clogging of the bag in the chute) can be resolved. However, operator care was required, which reduced production efficiency.

[0008] The present invention has been made to address such a problem, and overcomes an abnormal input of cut articles obtained by cutting a continuous product of a plurality of articles, such as small bags, and provides a conventional continuous bagging method. An object of the present invention is to provide a device for forcibly discharging cut articles, which can stably supply a small number of small bags of about several grams, which has been unstable in the device, and which can dramatically improve production efficiency.

Another object of the present invention is to provide a forcibly ejecting apparatus for cutting articles having different widths of the cutting articles, and having no parts to be changed or replaced, thereby improving the efficiency of changing the model.

[0010]

[Means for Solving the Problems]

 The present invention relates to a device for forcibly discharging cut articles, the present invention relates to a cutter section for cutting a continuous product of a plurality of articles into a required number of articles by a cutter blade, and a cutting section for cutting the cut articles to a target location. And a guide unit for guiding and feeding the product to a roller, wherein the roller unit is located below the cutter unit and is movable together with the cutter unit when the cutter unit performs a cutting operation; And a peeling member for pressing the article by the operation of the lever member to separate the article from the cutter section. It is a forced discharge device.

According to the present invention, when the peeling member is located below the cutter portion and the cutter portion performs a cutting operation, the roller body moves together with the cutter portion, and the roller body contacts the lever member, Since the peeling member presses the article by the operation of the lever member and separates the article from the cutter section, the cut article is surely separated from the cutter section when cutting a continuous article of a plurality of articles such as small bags. In other words, even if the small bag is about to adhere to the cutter blade due to the adhesion of glue to the cutter blade of the cutter unit, the article can be reliably separated from the cutter blade by pressing the article with the peeling member.

[0012] Therefore, it is possible to overcome the abnormal loading of the article and stabilize the loading of the light-weight small bag of about several g, which was unstable in the conventional continuous bag-filling apparatus, and to increase the production efficiency. It can be improved.

In the guide section, a transport belt is provided at a position facing the peeling member, and the article can be instantaneously sandwiched at the time of cutting and securely transported away from the cutter section. In addition, the cut article can be forcibly conveyed while being pinched and restrained, and can be conveyed without the cut article becoming unsteady due to the impact at the time of cutting the cutter, thereby preventing abnormal insertion. In addition, since the articles are forcibly conveyed, sticking of articles due to electrostatic charging of the chute does not occur.

In the guide section, a tension roller body for adjusting the tension of the transport belt may be provided, and a feed roller unit located below the peeling member and facing the transport belt may be provided. Therefore, by adjusting the tension of the conveyor belt, the distance between the peeling member and the conveyor belt and the pinching force can be appropriately set corresponding to articles of various thicknesses.

[0015] Furthermore, the conveyance of the cut article is not affected at all by the adhesion of the glue to the cutter blade or the electrification of the static electricity, and the cut article does not run out at all. Can be prevented.

In the guide section, the feed roller unit urges a plurality of roller members so as to be able to approach / separate from the conveyor belt, and further includes a second conveyor belt and at least a roller member below the conveyor belt. When the cutting article is sandwiched between the roller unit and the conveyor belt, the cutting article is sandwiched between the roller unit and the conveyor belt, and the roller body (upper conveyor can be added). ) And the second conveyor belt can sandwich and convey the cut articles. Therefore, the cut article can be always sandwiched and conveyed from the cutter section to a target place such as a conveyor line, and the cut article can be more reliably guided to the target place without being violated.

[0017]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of a forced discharge device provided in the continuous pouch cutting and charging device according to the embodiment of the present invention, and FIG. 2 is an explanatory view of a main part of the forced discharge device.

As shown in FIG. 1, in the continuous packet cutting and feeding apparatus, the continuous packet 1 in which each single packet (or pouch) 15 is continuous in a plurality of bands is formed by a pair of cutter blades 3 and 3 ′. The cutter unit 21 that cuts the seal portion 2 and divides it into one (or two or more if two or more required pieces) pouches 15 and the cut single packet 15 as the target And a guiding portion 22 for guiding and feeding the portion, and has a forced discharge device integrally or separately.

The forcible discharge device is located below the cutter unit 21 and is fixed integrally with the cutter blade 3 so that a hit roller (movable with the cutter unit 21 when the cutter unit 21 performs a cutting operation) is provided. 4), a lever member 5a located on the moving path of the contact roller 4 and operated by the contact of the contact roller 4, and the operation of the lever member 5a pressing the small bag 15 to perform the operation. And a release plate 5 for separating the pouch 15 from the cutter unit 21.

More specifically, the pouch 1 in the continuous packaging state is a product in which a product to be packaged is accommodated in a cylindrical resin sheet at an interval, and a portion where the product to be packaged is fused or adhered is used as a seal portion 2. The seal portion 2 is cut by the cutter portion 21 and divided into single packets 15.

In the cutter section 21, the cutter blades 3, 3 ′ face each other and are located along the horizontal direction, and the movable cutter blade 3 advances and intersects the fixed cutter blade 3 ′. It performs a cutting operation. The pouches 1 in the continuous packaging state are continuously fed between the cutter blades 3, 3 'by a transport mechanism (not shown). When the seal portion 2 comes to the cutting position, the cutter blade 3 advances toward the fixed cutter blade 3 'to cut the seal portion 2.

The contact roller 4 is fixed to a lower portion of the blade folder of the movable cutter blade 3 of the cutter unit 21 by a fixing means such as a bracket. Below the cutter blade 3, a lever member 5a and a peeling plate 5 are fixed to a support 5b back to back, and the support 5b is rotatably supported by a device base (not shown). The position is set such that the peeling plate 5 simultaneously touches (presses) the pouch 1 simultaneously with the cutting of the cutter blades 3 and 3 ′ of the cutter unit 21.

On the other hand, a guiding section 22 is provided below the cutter section 21. In the guide portion 22, as shown in FIG. 1 and, more specifically, as shown in FIG. 2, a conveyor belt 6 is provided at a position facing the fixed-side cutter blade 3 'peeling plate 5, and the lever member 5 is hit by a roller 4 at the time of cutting. The peeling plate 5 is rotated by being kicked by a, so that the small bag 15 is sandwiched between the small bag 15 and the conveyor belt 6, and the small bag 15 is surely conveyed in the direction of the roller 9 by the conveying force of the conveyor belt 6. .

In the guide section 22, the transport belt 6 is wrapped between pulleys separated from each other and circulates, and is continuously rotated by the drive motor 8. Further, a tension roller body 7 is provided on the opposite side of the side where the pouch 15 is conveyed to adjust the tension of the conveyor belt 6, so as to absorb the tension with respect to the fluctuation in the thickness of the pouch.

A plurality of, for example, four rollers 9, 9..., Which are located below the peeling plate 5 and face the conveyor belt 6, are rotatably mounted on the bracket 10 in the guide portion 22. It has an attached feed roller unit.

That is, the interval between each roller 9 and the transport belt 6 is set differently, and the interval between the transport belt and the first roller 9 on the upper side is slightly wider so that the small bag 15 can be easily sandwiched. The gap between the fourth roller 9 and the third conveyor belt 14 is slightly narrower so that the small bag 15 is sandwiched between the fourth roller 9 and the third conveyor belt 9. A relief is provided so that the small bag 15 can be securely mounted on the vehicle. In the guide unit 22, the feed roller unit is configured such that a bracket 10 provided with a plurality of rollers 9, 9 urges the rail 11 so as to be able to approach / separate the rail 11 from the conveyor belt 6. Can be moved along the rail 11 with one touch when setting the small bag 1 in the above or at the time of maintenance.

In the guide section 22, a conveyor (corresponding to a second conveyor belt) 14 is provided diagonally downward in the feeding direction below the conveyor belt 6, and the roller body 12 and the upper conveyor 13 are arranged above and opposed to the conveyor 14. A cut pouch 15 is sandwiched between the lower conveyor 14 and the roller body 12 and the upper conveyor 13 and guided from the cutter unit 21 onto the package 16 on the packaging machine conveyor 17 at the target location, thereby ensuring reliability. It is designed to be input to

The operation of the forced discharge device according to the embodiment will be described. When the pouch 1 to be cut is fed between the peeling plate 5 and the conveyor belt 6, the cutter blade 3 (moving side) moves in the direction of another cutter blade 3 '(fixed side). When the continuous pouch 1 is cut by the cutter blades 3 and 3 ', the contact roller 4 attached to the cutter blade 3 kicks the lever of the peeling plate 5, and the peeling plate 5 is cut to the conveyor belt 6 side. Rotate with 15 in between. When the pouch 15 comes into contact with the conveyor belt 6, the pouch 15 is fed in the direction of the rollers 9, 9,...

Therefore, even if the glue residue adheres to the cutting edges of the cutter blades 3 and 3 ′ and the adhesive force is present, the small bag 15 can be moved by the rotation of the peeling plate 5 and the conveying force of the conveying belt 6. Is forcibly fed in the roller setting direction from the cutter blade. Therefore, even when the small bag 15 is violent due to the cutting impact of the cutter unit 21, the violence can be prevented by the pinching action between the peeling plate 5 and the conveyor belt 6. Also, the direction of the center line of the pouch 15 does not tilt with respect to the loading direction. Therefore, since it is not necessary to regulate the width direction of the pouch 15 and to guide the pouch 15 in the flow direction, the corner of the pouch 15 contacts the chute side wall as shown by a U-shaped chute and sticks at the diagonal corner. The problem of being caught in the middle of the flow is eliminated.

The set of rollers 9 is composed of a plurality of (four in the embodiment) rotatable rollers, and is provided to face the transport belt 6. Further, the tension roller 7 of the transport belt is movable back and forth by a guide, and is configured to generate a pressing force by a spring. Therefore, even if the thickness of the small bag 15 sandwiched between the rollers 9, 9,..., The set conveyor belt 6 is different, the tension roller 7 automatically moves according to the thickness of the small bag 15.

As described above, the small bag 15 sandwiched between the peeling plate 5 and the transport belt 6 is fed between the set of the rollers 9, 9... Then, it is fed by the upper body while being sandwiched between the rotating roller 12 and the lower conveyor 14 and further between the upper conveyor 13 and the lower conveyor 14, and is thrown into the target position from each. Therefore, after the pouch 15 is peeled off by the peeling plate 5, the pouch 15 is always transported to the final loading position while being sandwiched, so that the center line direction of the pouch does not tilt with respect to the transport direction, and the Input is possible. Further, since a side wall having a U-shape is not required, there is no possibility that the bag is caught by friction between the small bag 15 and the side wall. Further, since there is no portion that allows the pouch 15 to drop freely before being put into the bag, the pouch 15 is always sandwiched and transported, so that even a small bag charged with static electricity can be put in without being clogged halfway.

The device for forcibly discharging cut articles according to the present invention is not limited to the above-described example, and various modifications can be made without departing from the scope of the present invention.

[0033]

[Effect of the invention]

 As described above, according to the present invention, it is possible to overcome the abnormal loading of the article and stabilize the loading of a few g of light weight pouch, which was unstable in the conventional continuous pouch loading apparatus. It is possible to dramatically improve production efficiency.

In addition, since the posture of the cut object such as a small bag is maintained so as to be sandwiched by the nip mechanism between the roller and the conveyor belt, clogging due to the slack of the small bag when the chute is used, and friction between the sliding surface of the chute and the surface of the small bag are reduced. Eliminates sticking to the chute surface due to static electricity. Furthermore, there is no need to manufacture, adjust, or replace the shoot guide, which can provide an excellent effect such as an advantage in total cost.
