Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a packaging machine for packaging a stack of books and the like with a wide tape as a roll paper.

[0002]

[Prior Art]

 Conventionally, as this type of packaging machine, for example, one disclosed in Japanese Patent Publication No. 3-33570 is known. Books such as magazines and paperback books are often handled in a state where they are stacked in appropriate numbers and packed in a wide tape. The packaging machine to which the present invention relates is mainly used for packaging such a laminate, and the work to be packaged is carried onto the table of the packaging machine and slid on it. While being sent to the packaging position, it is conveyed to the packaging position while pushing the tape that hangs vertically, and in the process, the tape is wound around the bottom, front, and top sides of the work, After that, a tape was attached to the back surface by a shutter that descended from above, and the tape was attached at the lower part on the back surface side and cut by a cutter.

[0003]

[Problems to be solved by the device]

 As described above, tape is cut at the same time as or at the same time as pasting at the final stage of packaging, but in some cases, due to tape distortion, it is not cut properly at a right angle to the longitudinal direction of the tape. In such a case, the lower end of the tape cannot be held or becomes incomplete, and the next packaging cannot be performed. If the tape is cut improperly in this way, it has conventionally been necessary to manually cut the tape with scissors or a cutter and reset the tape. There is a problem that it is troublesome to cut and it is difficult to cut straight at a right angle to the tape.

An object of the present invention is to eliminate the above-mentioned problems of the prior art. Therefore, if the tape is cut improperly, it is possible to easily and again cut the tape. The purpose is to provide a packaging machine that can be appropriately operated.

[0005]

[Means for Solving the Problems]

 The feature of the packaging machine according to the present invention is that it is provided with an auxiliary cutter 11 in addition to a cutter for cutting the tape in the regular packaging process, and the auxiliary cutter is provided on the upper part of the packaging machine main body. Further, it includes a cutter passage 13a for guiding the traveling of the auxiliary cutter, and preferably an air cylinder 14 for traveling the auxiliary cutter is provided.

[0006]

[Action]

 If the tape is cut incompletely or improperly by the main cutter, the auxiliary cutter may be moved by a manual operation or by an air cylinder so that the tape is positioned at a distance from the lower end of the tape. The tape can be cut appropriately, and the cutting is extremely easy.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show the essential parts of a packaging machine according to the present invention. As shown in the figure, the characteristic feature of this packaging machine is that the tape T is appropriately cut by a main cutter described below. If not, it includes an auxiliary cutter 11 used for cutting the tape, and the auxiliary cutter is installed on the upper part 12 of the packaging machine body. A guide 13 having a passage 13a for guiding the traveling of the auxiliary cutter 11 is provided. As described above, the wrapping machine plays a role of wrapping a work such as a laminated body such as a book in a wide tape.

As is apparent from FIG. 1, the auxiliary cutter 11 is configured to run at a right angle to the tape T that is fed to the packaging position through the upper portion 12 of the body of the packaging machine, and in the illustrated example. The guide 13 is constructed as a flat plate in which a linear slot or slit 13a is formed, and the auxiliary cutter 11 is loosely fitted in the slit and thus guided by the slit. Needless to say, the guide of the auxiliary cutter 11 may have another structure.

The operation of the auxiliary cutter 11 may be performed manually by an operator, but may be performed by power if desired, and therefore, as shown in FIGS. 1 and 2, it is preferable to use an air cylinder, particularly an air cylinder. A rodless type air cylinder 14 is provided.

FIGS. 3 and 4 show an example of a packaging machine equipped with the auxiliary cutter 11. As shown in FIG. 3, a conveyor 1 for carrying in a work A and a predetermined position of the conveyor 1 are provided. Further, it is provided with a stopper-2 for stopping the work and a first pusher-3 for pushing out the work on the table 4 of the packaging machine. At the position of the table 4, the first press plate 5 is operated by the cylinder 5a to press the work, and the work is pushed to the packaging position while being pressed by the press plate 5. A second pusher 6 operating on the cylinder 6a and a second press plate 7 for pressing the work in the packaging position are provided. Further, in the packaging position, there is a shutter device 8, a gluing member 9 and a main cutter 10 arranged below the shutter device 8.

On the other hand, a tape used for packaging is fed from a reel 15, passes through a dancer roll 16, and passes from a tape feeding roller group 17 through a tape guide 18. The tape is lowered vertically to the packaging position, and its lower end is pressed by a tape presser 19. Therefore, the work A1 carried into the table 4 is pushed out by the second pusher 6 when it is sent to the packaging position under the second press plate 7 to push out the tape from the bottom, front and top surfaces. Tape is wrapped around three sides. A2 indicates a work sent to the packaging position.

When the work is thus sent to the packaging position, the tape is glued to the lower end of the tape as shown in FIG. 5, and as the main cutter 10 rises, the tape folding at that position is performed. By 20 the glued part of the tape is bent upwards. Then, the tape is taken out by lowering the shutter device 8 to attach the tape to the back surface of the work, and when the tape is further lowered, the tape is overlapped with the tape portion to complete the packaging. At the same time, the main cutter is inserted between the bifurcated tape receivers 21 of the shutter device to cut the tape, the main cutter 10 and the shutter device 8 return to their original positions, and new tape is inserted. The tape end is lowered to some extent and is pressed by the tape presser 19 to prepare for the next packaging.

Usually, the main cutter 10 appropriately cuts the tape, that is, the tape is cut straight at a right angle to its longitudinal direction, but the tape is distorted or wrinkled, or the tape is cut. -If the tape is not cut properly for some reason, such as when setting a new tape, the tape end will be incompletely pressed and the next packaging will be hindered.

In such a case, the auxiliary cutter 11 is manually operated by an operator, or the air cylinder 14 is operated to cut the tape at a position apart from its lower end to a certain extent. It is preferably performed because it is guided by the cutter passage 13a. After the tape is cut by the auxiliary cutter 11, the tape is ejected by the operation of the feed roller 17, the lower end of the tape is moved to the position of the tape presser 19, and the taper presser 19 is used. Hold and start the next packaging cycle.

As shown more clearly in FIG. 6, a tape guide (paper receiver) 18 made of a curved plate is provided at the upper part of the packaging machine for lowering the tape to the packaging position. It is preferable that a cutter passage 13a as a slot is provided on the upper portion of the guide 18. A paper presser 22 made of a thin plate is provided along the upper part of the tape guide 18, and the tape is clamped between them, so that the tape is stable at that position and the cutting by the auxiliary cutter is good. Done.

[0016]

[Effect of the device]

 As described above, according to the present invention, when the cutting of the tape by the main cutter is not properly performed, the cutting of the tape can be appropriately, easily and quickly performed by the auxiliary cutter. Therefore, the workability in such a case can be improved, and the downtime (loss time) of the packaging machine can be minimized.
