Description

[Detailed description of the invention] The present invention cuts the tape supplied from the tape holder into an appropriate length in the guide path, which is highly safe and easy to work with, has a simple structure, and is therefore a tape with fewer failures. Relating to a cutting device.

This type of device has the function of simply cutting the tape supplied from the holder into an appropriate length, or the tape supplied from the holder is pasted or wrapped around an article on a workbench. There is a type with a so-called workbench that can be turned and cut the end.

However, in any of the above-mentioned types of devices, in the conventional device, the cutting blade for cutting the tape is fixed in a state protruding from the guide path. As a result, users are often injured by the cutting blade, which poses a safety problem. Also, especially in the latter type of equipment mentioned above,
When packaging items on a workbench,
There was also the problem that work efficiency was extremely low because care had to be taken not to touch the cutting blade.

In addition, there are known devices in which the cutting blade protrudes only during cutting, such as those described in Japanese Utility Model Publication No. 51-47581 and Japanese Utility Model Publication No. 47581.
These had the disadvantage that they had a complicated structure and were prone to break down due to dirt entering the receiving groove.

The present invention was made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a tape cutting device that is extremely safe, has a simple structure, and is therefore less likely to break down and has good workability.

In the present invention, the cutting blade is normally recessed below the guide path, and during the cutting operation, the cutting blade protrudes above the guide path to cut the tape, but instead of simply cutting the tape into the horizontal bar described later. The above objective is achieved by sliding the blade mounting plate.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the device main body 1 has a base 2

As shown in FIGS. 2 and 3, an L-shaped workbench 8 having three mounting holes 8a formed in the horizontal direction is attached to the upright portion 3. As shown in FIGS. The mounting structure of the workbench 8 includes each mounting hole 2a of the base 2.
Bolts 9 inserted through each of the mounting holes 8a of the workbench 8 are tightened with wing nuts 10, but the size of the article M can be adjusted by changing the mounting holes 2a formed in two upper and lower stages. The height of the workbench 8 can be changed as appropriate.

The rising mounting plate 4 is formed in an L-shape, and near both ends thereof, mounting holes 4a are formed into oval shapes as shown in FIGS. The mounting plate 4 is fixed to the base 2 by inserting bolts 11 into the mounting holes 2b and tightening them with wing nuts 12.

Further, a tape holding section 13 that rotatably holds a roll-shaped tape is provided in the bearing hole 4b. A tape holding member 15 formed in the shape of a reel and fitted inside the wound tape to hold the tape T is rotatably attached to the tape holding member 15 around a bolt 14 and fixed with a nut 16.
The mounting hole 4a is for appropriately selecting the horizontal position of the mounting plate 4 according to the width of the tape T to be fitted with the tape holding member 15, and the bearing hole 4b is for selecting the horizontal position of the mounting plate 4 according to the width of the tape T to be fitted with the tape holding member 15. Tape holding member 1 according to
This is for appropriately selecting the vertical position of 5.

As shown in FIG. 1, a bolt 17 is inserted into a bearing hole 4c formed in the middle of the mounting plate 4. As shown in FIG. A guide roller 18 for guiding the tape T into a guide path, a flange 19 for preventing meandering of the tape T, and a coil spring 20 are sequentially inserted into this bolt 17, and a nut 21 is screwed into the other end. There is. The biasing force of the spring 20 is the flange 1
9 to the guide roller 18, the tension of the tape T can be adjusted as appropriate by changing the rotational load on the guide roller 18 due to the biasing force of the spring 20 depending on the degree of tightening of the nut 21. . Further, the guide roller 18 is connected to the tape T.
When the tape is an adhesive tape, for example, one made of polyoxymethylene resin or polyacetal (Delrin: trade name manufactured by DuPont) is preferably used so that it can be guided without resistance.

A U-shaped rising wall forming plate 5 having a pair of opposing standing side plates 6 and 7 is fixed to the base 2. In this mounting structure, as shown in FIG. The structure shown below is an example.

The rising wall forming plate 5 is provided with a guide passage 30 and a cutting part 36, and this guide passage 30
The cutting section 36 will be explained with reference to FIGS. 2 and 3. Bearing holes 6a, 6b, 7a, 7b are formed above each side plate 6, 7, and the tape T
A channel-shaped guide plate 3 forming a guide passage 30 of
There are through holes 31a, 31b, 31c, 3 on both sides of 1.
1d is formed. And bearing holes 6a, 7a
Bolts 32, 3 are installed in the through holes 31a, 31c, the bearing holes 6b, 7b, and the through holes 31b, 31d, respectively.
3 is inserted through the guide plate 31 and tightened with nuts 34 and 35, so that the guide plate 31 is installed and fixed between the side plates 6 and 7. The guide plate 31 installed between the side plates 6 and 7 is set to be located below the upper edges of the side plates 6 and 7. That is, this is to ensure safety by surrounding the cutting blade 42 with the upper edge portions of the side plates 6 and 7 when the cutting blade 42 is projected, which will be described later. The guide path 30 that guides the tape T in this way
is composed of a guide plate 31 and upper edge portions of both side plates 6 and 7 extending upward from the guide plate 31.

In addition, an operating member 37 provided in front of the guide plate 31 has a triangular-shaped opposing side plate 3 extending downward.
8 and 39, and through holes 38a and 39a are formed above each side plate 38 and 39 near the cutting portion, respectively.

The bolt 32 as a pivot of the operating member 37 is inserted through the through holes 38a and 39a, and the bolt 32 is inserted through the through holes 38a and 39a.
can be rotated around this axis. Further, a horizontal bar 40 is suspended below both side plates 38 and 39. Further, below the guide plate 31, a channel-shaped cutting blade mounting plate 41 is provided, which has through holes 41a and 41b formed on both sides of the base end. On the upper surface of the cutting blade mounting plate 41,
A cutting blade 42 having a chevron-shaped tip is fixed. The lower surface of the cutting blade mounting plate 41 is in contact with the horizontal bar 40, and the through holes 41a, 41b
The bolt 33 is inserted through as a pivot. Furthermore, a coil spring 43 as a biasing means is stretched between the mounting plate 5 and the tip of the cutting blade mounting plate 41 so as to bias the cutting blade mounting plate 41 in the counterclockwise direction in FIG. ing. As the cutting blade mounting plate 41 is biased, the operating member 37
is biased clockwise in FIG. 2 via a horizontal bar 40. As a result, the operating member 37 and the cutting blade mounting plate 41 are stabilized with the rear end of the operating member 37 in contact with the tip of the guide plate 31, and under normal conditions, the upper surface of the operating member 37 is aligned with the guide path surface for the tape guide. forming a passage.

Next, how to use and operate the above device will be explained.

First, a desired tape T wound into a roll is loaded into the holding part 13, and the leading end of the tape T is wound around the guide roll 18, and then guided to the guide path 30. After pasting or winding the tape T around the article M on the workbench 8, the operating member 37 is pushed down by the article M, the tape, or by hand. As a result of this pressing down, the horizontal bar 40 slides on the lower surface of the mounting plate 41 against the biasing force of the spring 43, as shown by the chain line in FIG. and the cutting blade mounting plate 41 rotates clockwise.
As a result, the slit-shaped opening formed in the abutment area between the guide plate 31 and the operating member 37 constituting the guide passage 30 in the cutting blade 42 opens wide, and the cutting blade protrudes upward to cut the tape T. .

Then, when the depression of the operating member 37 is released,
The operating member 37 and the cutting blade mounting plate 41 are returned to the position shown by the solid line in FIG. 2 by the biasing force of the spring 43, and the cutting blade 42 is retracted into the lower side of the guide passage.

The cutting blade advantageously used in the device of the present invention is
It has a blade part formed in a sharp chevron shape and a width sufficient to cut the tape, has one or more holes for mounting and fixing, and is configured so that it can be replaced if necessary. ing. Further, a hexagonal type with blades formed on the upper and lower sides can also be advantageously used.

As mentioned above, in the tape cutting device according to the present invention, the rotatable operating member 37 is normally connected to the spring 43.
The cutting blade 42 is biased to form a guide path surface that coincides with the fixed guide plate 31, and the cutting blade 42 is recessed under the guide path 30, and the operating member 37
When the cutting blade 42 is pressed, the cutting blade 42 is slid by the horizontal bar 40 and protrudes into the guide passage 30 to cut the tape T.
The sliding part is lightweight so that it can be displaced in conjunction with the operating member 37 to cut the cutting blade 42.
Since the tape is always recessed under the guide passage 30 except when cutting, it is extremely safe, and cutting the tape can be done by simply pushing down the operating member, and the tape is not fitted into a groove. It has the advantage of being less likely to break down.
