Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutting device for continuous packages.

[0002]

[Prior art]

 For example, liquid packages such as natto sauce and mustard are packaged in bags by an automatic packaging machine.When the packages come out of the automatic packaging machine, the packages are separated by a seal. It is in a continuous state. Therefore, when a packaged product is to be further packaged together with another product, such as natto, it is necessary to separate the packaged product from the continuous packaged product by cutting it at the seal part. Examples of these continuous packaged products and cutting devices are shown in, for example, JP-A-64-37330 and JP-A-5-34112.

The continuous packaged products packaged by the automatic packaging machine as described above are once boxed and stocked. Then, when the bag is packed together with other products, it is cut by loading the boxed continuous packaged product into a cutting device. In this case, when packaging continuous packaging, it is stocked by sequentially folding it back into a predetermined length. Therefore, folding back, wrinkles, and the like may occur at the folded back portion.

[0004] When such a crease is formed, when the package is individually cut from the seal portion by the cutting device, immediately after cutting the most advanced package of continuous packages, a new package is newly added. The package at the top is restored to the bent state due to the folding. Therefore, when the continuous package is sent toward the cutting blade for the next cutting, the folded package will rise to the surface of the cutting blade.

In such a state, it becomes impossible to feed the continuous packaged product toward the cutting blade thereafter, and when the cutting blade is operated as it is, a part separated from the seal part, That is, the packaging part of the packaged product is cut into pieces. Whenever such a situation occurs, it is necessary to stop the machine each time, correct the loading of continuous packages, and clean the spilled packages by slicing. Therefore, the operating rate of the machine will be extremely poor.

[0006]

[Problems to be solved by the device]

 The present invention is intended to cut a package individually from a continuous package so that even if the continuous package is folded or wrinkled, it can be accurately cut without being affected by the crease. And

[0007]

[Means for Solving the Problems]

 According to the present invention, the cutting mechanism is composed of a fixed cutting blade and a movable cutting blade, and a fixed guide and a movable cutting blade are integrally driven on the upper part of the cutting mechanism so that the cutting mechanism continuously packs them. Before cutting the product, a first pressing member that elastically presses the package to be cut next in the continuous package against the fixed guide is provided, and the lower part of the cutting mechanism is provided. The cutting-edge packaging that passes through the cutting mechanism is driven integrally with the movable cutting blade between the conveyor belt unit and the cutting mechanism and the nip-type conveyor belt unit that sends out the packages separated by the cutting mechanism. A second pressing member that elastically presses the product onto the belt of the conveyor belt unit is provided.

[0008]

[Action]

 By the operation of the movable cutting blade, the most advanced package is elastically pressed against the belt of the conveyor belt unit by the second pressing member until the continuous package is cut from its seal portion. Since the belt is driven continuously, tension is exerted on the continuous package, and it is in a tight state. The package to be cut next is pressed against the fixed guide by the first pressing member.

In this state, when the movable cutting blade cooperates with the fixed cutting blade to cut the most advanced packaged product from its seal portion, the most advanced packaged product is directly sent to the conveyor belt unit. At this time, the package to be cut next is pressed against the fixed guide by the first pressing member, so even if the package is folded, the most advanced package After being cut, it cannot be restored as it was folded.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A is a continuous packaged product, and is constituted by a packaged product part B that wraps the packaged product and a seal part C that connects each packaged product part B in the longitudinal direction. By cutting from the center of the seal portion C, the packaged products are individually separated from the continuous packaged product A 1. These configurations and the disconnection operation are as described at the beginning.

A cutting mechanism 1 is composed of a fixed movable blade 2 and a movable cutting blade 3. The cutting edge 3A of the movable cutting blade 3 is inclined, and when the seal portion C of the continuous packaged product A is sent between the two cutting blades 2 and 3 by an appropriate detector, the movable cutting edge 3A is cut. By driving the blade 3 toward the fixed cutting blade 2, the most advanced packaged product D and the packaged product E to be cut next are cut from the continuous seal portion C. Reference numeral 4 denotes a pair of feed rollers that feed out the continuous packaged product A by sandwiching it.

According to the present invention, a fixed guide 5 and a holding member 6 made of, for example, a rubber plate for elastically pressing the package E against the fixed guide 5 are provided on the upper portion of the cutting mechanism 1. There is. The pressing member 6 is moved integrally with the movable cutting blade 3. For that purpose, a bracket 8 is attached to a movable holder 7 to which the movable cutting blade 3 is attached, and a holding member 6 is attached to this bracket 8 via a leaf spring 9.

Reference numeral 10 denotes a nip type conveyor belt unit for sending out the cut packaged products, which is composed of a pair of belts 11 and 12, and is continuously driven in the arrow direction by a drive source (not shown). Then, the cut packaged product is sent downward as it is sandwiched between the belts 11 and 12.

A pressing member 13 is provided between the conveyor belt unit 10 and the cutting mechanism 1 and is made of, for example, a rubber material, and also moves integrally with the movable cutting blade 3. Therefore, it is attached to the moving holder 7. By this movement, the packaged product D is pressed against the belt 11. Reference numeral 14 is a fixed guide that prevents the package D pressed by the pressing member 13 from escaping toward the upper portion of the belt 11.

In the above configuration, it is assumed that the package D passes through the cutting mechanism 1 as shown in FIG. 1 and the seal portion between the packages D and E reaches the cutting position by the cutting mechanism. When the detector detects the seal portion at this position, the movable cutting blade 3 is driven by a drive source (not shown) and moves toward the fixed cutting blade 2.

Before the movable cutting blade 3 meshes with the fixed cutting blade 2, the pressing member 6 elastically presses the package E into the fixed guide 5, and the pressing member 13 presses the package D into the belt 11. Elastically hold it down. Due to this elastic pressing, the tips of the pressing members 6 and 13 are bent downward along the surface of each package. This state is shown in FIG.

When the package D is pressed against the belt 11 by the pressing member 13, the belt D, which is constantly driven, applies tension to the package D, and thus the continuous package A, along the driving direction of the belt 11. It acts and becomes tense. After that, the movable cutting blade 3 overlaps with the fixed cutting blade 2, and the seal portion C is cut. Then, the packaged product D drops, is sandwiched by both belts 11 and 12, and is sent out downward.

On the other hand, at the time of this cutting, since the pressing member 6 presses the package E into the fixed guide 5, after the package D is cut, the package E or the package E and the next package are temporarily provided. Even if there is a fold in the seal part between and, it will not be restored as it was.

When the cutting operation is finished as described above, the movable cutting blade 3 returns to the initial position. In accordance with this, the pressing members 6 and 13 also return to their initial positions. Then, the continuous package A is transferred by the rotation of the roller 4 for cutting the next package. This is repeated below.
