Description

[Detailed description of the invention] The present invention is an automatic adhesive tape pasting and cutting device, more specifically, it is installed in the process where the items to be pasted with adhesive tape are automatically conveyed, and the tape is delivered to the tape pasting area. The present invention relates to a device that automatically sends out a tape in accordance with the movement of articles when a pair of rolls for use is positioned, and automatically cuts the tape as soon as the required length has been pasted.

With the development of automatic equipment, various automatic adhesive tape feeding and cutting devices have become available, but all of them tend to be complicated and expensive.

The present invention provides an automatic adhesive tape laminating and cutting device that has a relatively simple structure, less trouble, and is inexpensive.

A preferred embodiment will be illustrated and explained in detail below.
Fig. 1 is a plan view of an embodiment of the device according to the present invention, showing the non-operating state, Fig. 2 is a front view of the same, Fig. 3 shows the tape laminating start operation of the device, and Fig. 4 shows the tape laminating operation. The progress of the fifth
The figures are plan views of essential parts showing the tape cutting operation, and FIG. 6 is a partially cutaway perspective view of the blade.

The gist of the device of the present invention is: A tape mount 3 rotatably pivoted on a support 1 by a fixed shaft 2, and having a pair of rolls 9, 10 for holding the tape rotatably mounted on one end thereof. Then, this pedestal 3 is rotated within an appropriate range around the fixed shaft 2 and connected to the tape pedestal 3 by the movable shaft 4 so that the pair of rolls 9 and 10 are placed in the bonding surface area a of the article A. The tape holder 3 is normally held in a non-rotating state by an actuating rod 6 equipped with a tension spring 7, and an excitation provided opposite to the actuating rod 6 to resist the tension spring 7. A solenoid valve 8 that attracts the operating rod 6, a cutter blade 11 that is arranged so as to be able to move back and forth at a position slightly apart from the bonding surface area of the item A, and a cutter blade 11 that is energized to attract and move the blade 11 in the direction of cutting progress. It is comprised of a solenoid valve 12 for holding the blade 11 in the retracted position, and a tension spring 14 disposed opposite to the solenoid valve 12 for normally holding the blade 11 in the retracted position.

In the above configuration, the pair of rolls 10 is rotated only in the feeding direction of the tape T by a clutch bearing means (not shown), and is not rotated in the tape feeding direction, so that the pair of rolls 9 and 10 are Tape T creates tangles,
No sag is formed.

As can be seen from Figure 2, one roll 9 is provided with two small diameter parts 91 and 9° in the axial direction, and this is because the adhesive attached to both edge parts of the tape T is attached to the roll. Based on the consideration that it will not shift to 9.

As the material of the roll 9, silicone rubber with good releasability is desirable.

Reference numeral 20 denotes a tape restraining roll provided on one side of the support base 1 corresponding to the pasting surface area a of the item A after the tape pasting and cutting of the item (4) is completed, The fixture 19 is pivotally supported by a shaft 18 and is attached to a frame 22 by another shaft 21 so that the position of the operating surface of the roll 20 can be adjusted to move forward and backward with respect to the surface area a. .

As an example of item A, the figure shows a case in which a rectangular parallelepiped is wrapped in a wrapper r and the side edge folded portion (not shown) of the wrapper r is sealed with adhesive tape T. Item A is wrapped along one side of the proposed device. It is sent out in the direction of the arrow in FIG. 3 by a conveyance means not shown.

Reference numeral 5 denotes a long groove provided in the operating rod 6, which restricts the longitudinal position of the operating rod 6 when the spring 7 is tensioned and the solenoid 8 is attracted by engaging with the fixed shaft 51.

The blade 11 is fixed at one end to a movable shaft 13, and when the solenoid 12 is energized, the shaft 13 moves to the right in the figure along the long groove 17 of the blade guide plate 16.

The blade 11 has a cutting edge 111 on its axis as shown in FIG.
It forms a triangular blade with several 111 marks.

Reference numeral 15 is a hanging shaft for the spring 14.

Next, the operating state of the present invention will be explained.

When the solenoid 8 in Fig. 1 is not activated, the adhesive tape roll R is mounted on the fixed shaft 2, the adhesive surface is positioned on the right side in the figure, and the tape T is pulled out between the pair of rolls 9 and 10, so that the tip ends as shown in the figure. It is located on the working surface of the roll 9.

Next, the solenoid 8 is energized to attract the operating rod 6, thereby deflecting the tape stand 3 around the fixed shaft 2, and placing the operating surface of the roll 9 in the bonding surface area of the article A (FIG. 3).

While maintaining this state, the article A approaches the pair of rolls 9 and 10 in the direction of the arrow in FIG. The rolls 9 are used to continuously bond the surface area a by rolling out the sheets from a distance of 100 mm (see FIG. 4).

As soon as the tape T completes pasting of the surface area a, the solenoid 8 is turned off to return the counter roll 9 and 10 to the state shown in FIG. is excited to cause the cutter 11 to protrude and cut the tape T (see FIG. 5).

As a result, the relationship between the tape T and the tape stand 3 becomes exactly the same as that shown in FIG.

It is desirable to provide the tape suppressor roll 20 because it can suppress the tape from above the surface of the tape and ensure sufficient tape bonding.

The tape feeding, pasting, and tape cutting operations are completed as described above.

The next item A is dealt with in the same manner.

The solenoids 8 and 12 are controlled by a time limit using the moving speed of the article A and the length of the surface area a as variables.

As described above, in the present invention, the waiting time for adhesive tape lamination, automatic lamination, adhesive tape return, and tape cutting are performed accurately with a relatively simple structure, so the cost is low and there are few failures. It has the benefit of...
