Description

[Detailed Description of the Invention] The present invention relates to a machine for attaching a synthetic resin tape for carrying to a package such as a box or bag whose surface is made of synthetic resin.

Conventional technology Conventionally, in order to attach carrying tape to a package such as a box whose surface is covered with synthetic resin, or a box or bag made of synthetic resin, it is necessary to manually attach both ends of the tape to the package, or to attach the tape to the package. Currently, they are processed so that tape can be attached to them, but the former requires labor and is inefficient, and the latter has the drawback of increasing costs.

In view of these current circumstances, the present invention is designed to efficiently and reliably attach synthetic resin tape for hand-held use to packages whose surfaces are made of synthetic resin.
A transfer device that transfers a package with the tape attachment surface on the side; a tape feed device installed above one side of the transfer device; a tape pulling device that can be freely pinched by pulling the tape to the side; a tape cutting device that cuts the tape pulled by the tape drawing device near the tape feeding device; and a tape cutting device that presses the tape cut by the tape cutting device to the side surface of the package. a pair of tape bending devices that bend both ends of the tape pressed against the side surface of the package to the top and bottom surfaces of the package; and a pair of tape folding devices that weld the tape bent portions to the package. The gist of the system is that it consists of a heat sealing device.

An embodiment of the present invention will be explained with reference to the drawings. A transfer device 2 formed of a transfer belt, a transfer roller, etc. provided on a machine base 1 is used to transfer packages A made of a heat-sealable material such as synthetic resin to a tape. The tape is transferred with the mounting surface on the side, and a plurality of tapes (three in FIG. 1) are sent to the tape mounting section 4 by a pusher 3.

On one side of the transfer device 2 in the tape attachment part 4, there is a fixed guide 5 that supports one side of the package A.
A tape feeding device 8 having a winding reel 7 is provided on the upper part of the frame 6 provided on the machine stand 1 on the other side, and a tape made of synthetic resin is wound on the winding reel 7. A tape drawing device 10 is provided on a machine base below the tape feeding device 8 and is moved up and down by an air cylinder 9. There is.

As shown in FIGS. 4 and 5, the tape drawing device 10 includes an elevating rod 11 that is raised and lowered by an air cylinder 9, and a pair of clamping pieces 12, 12 provided on the upper portion of the elevating rod 11. The clamping piece 12,
When the elevating rod 11 is raised and lowered by an air cylinder 9 and reaches the tape B being fed out from the tape feeding device 8, the piston 13 operates to project and close the clamping pieces 12, 12.
The tape B is sandwiched therebetween, and the lifting rod 11 is then lowered to pull the tape B to the center of the tape attachment surface of the package A.

Further, a tape restraining device 15 is provided on the frame 6 so as to be able to protrude freely with a cylinder 16, and the tape restraining device 15 presses the tape B stretched on the side surface of the package A through a support rod 14 to the side surface of the package A. A pair of tape bending devices 17 are provided at the upper and lower portions of the tape bending device 15 with cylinders 18, respectively, so that the tape bending devices 17 can be retracted and retracted, and a tape cutting device 19 having a heat cutter or other cutting tool at the tip is provided on the lower side of the tape feeding device 8. It is provided with a cylinder 20 so as to be able to protrude freely.

Therefore, the operation timing of each cylinder and piston is such that when the tape drawing device 10 clamps the tape B and descends, the tape cutting device 19 and the tape restraining device 15 operate to protrude almost at the same time, and the tape cutting device 19 cuts the tape. Cut B and use tape holding device 15
presses the cut tape B onto the side surface of the package A, while the clamping pieces 12, 12 are regulated and controlled so as to release the tape B, and then the tape bending device 17
is adjusted so that the upper and lower ends of the cut tape B are bent along the upper and lower surfaces of the package A when the tape B is projected and operated.

A pair of heat sealing devices 2 are provided at the upper and lower parts of the frame 6 to weld the bent portion of the tape to the package A.
1, and the pair of heat sealing devices 21 include a rotating shaft 22, a sliding rod 24 that slides via a crank lever 23, and a sliding rod 24 that is pivotally supported at the front end of the sliding rod 24 and has a It is composed of a swinging lever 26 having a heat roller 25 and a pressing cylinder 27 that is connected to the swinging lever 26 and swings it. After pressing tape B onto surface B, the rotating shaft 22 rotates to slide the sliding rod 24 forward, and the heat roller 25 transfers the tape B to the package A.
After the heat roller 25 is separated from the tape B surface of the package A by the pressing cylinder 27, the sliding rod 24 slides backward.

Since the embodiment of the present invention is constructed as described above, when the package A whose surface is wrapped with synthetic resin is transferred to the tape attachment section 4, the tape drawing device 10
After the tape B is raised and the tape B is clamped between the clamping pieces 12, 12 and lowered (see Fig. 7A), the tape restraining device 1
5 and the tape cutting device 19 operate to cut the tape B and simultaneously press it against the side surface of the package A (see FIG. 7B). Then, the tape bending device 17
is projected and the upper and lower ends of the cut tape B are bent onto the upper and lower surfaces of the package A. (See Figure 7 C) Next, the heat roller 25 is pressed against the bent part of the tape by the operation of the pressing cylinder 27, and at the same time the sliding rod 2
4 rolls forward and welds the tape B to the package A, and then the heat roller 25 separates from the package A and the sliding rod 24 retreats (FIG. 7D,
(See E and F) The handle of tape B is attached to the package A and taken out from the tape attachment section 4.

In the above embodiment, the tape B is pulled in the vertical direction, but it is of course possible to pull it in the horizontal direction. The structure of each device is not limited to the above embodiment.

The present invention involves pulling out a tape from one side of a synthetic resin or a package such as a box or bag covered with synthetic resin, cutting the tape to a predetermined length, abutting it against the package, and applying the tape along the package. It is possible to automatically and efficiently heat-weld synthetic resin carrying tape by bending and welding it to the package, making it easy to carry this type of package, and not requiring any processing on the package. It has excellent features and practicality, such as low cost since it is not required.
