Description

[Detailed description of the invention] a. Industrial application field This invention relates to a device for guiding label tapes of different widths in a label tape supply system in which a label is temporarily pasted on one side of the tape. , a continuous labeling machine that is equipped with a label tape roll, feeds tape from it, and peels labels one by one from the tape, with one side of the mechanism all free ends. This invention relates to a device that reliably guides a label tape.

b. Prior Art A continuous level pasting machine with a free end on one side of a mechanism that supplies labels temporarily pasted onto a tape and sequentially peels the labels one by one from the tape was developed by the inventor of the present application. (Special application 1982-
130666, 59-184191).

One of the features of this cutting-edge machine is that label tapes of various widths can be freely used.

c. Problems to be Solved by the Invention In the above-described continuous labeling machine, only the other side of the label tape supply system is supported by a common main frame, one side of which is all free ends. Therefore, there is a need for a device that guides the label tape even on its free end side. However, when the widths of the label tapes to be loaded are different, it is desirable that the mounting position of the guide device on the free end side can also be adjusted in displacement in accordance with the width of the label.

The purpose of this invention is to provide a device that reliably guides various types of label tapes with different label widths, in order to satisfy the above requirements.

d.Means for solving the problem This invention is based on the label supply system of a continuous labeling machine, which has a mounting shaft with a length that allows the label tape of the maximum width (hereinafter referred to as the total width) to be mounted, and a mounting shaft with the same length. A tape folding piece is provided so as to protrude from the main frame in a cantilevered manner in the same direction, and a pair of guide rolls having a length shorter than the total width are installed opposite the tape guide surface of the tape folding piece. A full-width length shaft for rotatably supporting one of the rolls near the main frame is provided in a cantilevered manner protruding from the main frame, and the shaft is inserted into the free end of the shaft of one of the rolls. An adjustable frame having a hole capable of adjusting and fixing movement along the axis is provided, and a shaft of a length capable of rotatably supporting the other of the guide rolls is separated from the adjustable frame. A guide rod of a length that can be hung over the mounting shaft is provided in a cantilever manner and protrudes from the adjustable frame.

e Function When mounting label tape rolls on a shaft, remove the adjustable frame from the shaft of one roll, load it, pull out the label tape at the tip from the label tape roll, and guide it to the tape folding piece. .

Then, fit the hole of the adjustable frame into the free end of the shaft of one of the rolls, move it along that axis to a depth corresponding to the width of the label tape, and place the adjustable frame at the position where it touches the edge of the tape. is fixed on the axis of one roll.

The pair of guide rolls is shorter than the length (total width) of the label tape roll mounting shaft, for example approximately 1/2
(half width), and one guide roll is installed closer to the main frame side, and the other guide roll is installed closer to the adjustable frame side, so the adjustable frame can be adjusted between full width and approximately half width. Can be moved. Since the guide rod is integral with the adjustable frame, when the adjustable frame is adjusted and fixed, the guide rod can also guide the tape from the label tape roll mounting shaft at an optimal position.

f Example First, a general configuration example of a continuous label pasting machine with one free end will be described.

A shaft 6 on which a roll 5 wrapped with label tape is mounted, a pair of guide rolls 7 and 8, and a tape folding piece 1
0, a pair of nipping rolls 11 and 12 for feeding the tape 5a are both fixed or rotatably supported on the entire surface of the L-shaped main frame 9, and each of their front ends, except for the nipping roll 12, with a free end without any support material.

Of the pair of nipping rolls 11 and 12 for feeding the tape, one 11 has a large diameter and has a non-slip knurling, for example, engraved on its circumferential surface, while the other 12 is made of rubber with a small diameter. The rotating shaft 17 is supported by a long hole 19 of a bracket 18, and is constantly pressed toward the circumferential surface of the large diameter roll 11 by the action of a leaf spring (not shown).

A saw blade 21 is provided along the back side of the bracket 18, and the tape 5a that has been fed is cut there at any time.

The power transmission system to the nipping rolls 11 is as follows. That is, a gear (not shown) having the same diameter as the roll 11 and a pinion 26 are integrally fixed to the shaft 24 of the roll 11, and the pinion 26 engages with a large relay gear 27, The large gear is free with respect to the relay shaft 28, and the relay shaft 2
A drive source pinion 29 rotatable relative to the pinion 8, and a ratchet wheel 3 integrated with the pinion 29.
0, and a ratchet pawl (not shown) that engages with the wheel is provided on the side surface of the large gear 27.

The driving source pinion 29 engages with a large-diameter driving sector gear 33, and the swing axis 34 of the sector gear is rotatably mounted on the main frame 9. Furthermore, a driving lever 3 is installed at the base of the sector gear.
The proximal end of the lever 35 is fixed, and the free end of the lever 35 projects above one end of the main frame.

Therefore, when one end of the main frame 9 is gripped with four fingers, the thumb is placed along the top surface of the drive lever 35, and the thumb is pushed down, the lever 35 will rotate around the support shaft 34. Displaced,
The lever 35 and the sector gear 33 rotate the driving pinion 29, and the ratchet wheel 30 integrated with the pinion 29 rotates.
is rotated counterclockwise in FIG. Then, the rotation is transmitted to the relay large gear 27 via a ratchet pawl (not shown), and the pinion 26 that engages with the large gear is rotated. A driven gear (not shown) that engages with the pinion via a gear (not shown) integrated with the pinion is also rotated. In this way, the pair of nipping rolls 11 and 12 pull out the tape 5a sandwiched between them by a distance corresponding to the rotation angle of the lever 35, so that the roll 5 is unwound and the label 5b is pulled out from above the tape 5a at the folded piece 10. is peeled off and held out forward. The label 5b immediately after being peeled off from the tape 5a is applied onto the object surface by the pressure roll 40.

Now, in the present invention, the width of the mounting shaft 6 of the label tape roll 5 and the tape folded piece 10 is set to a length that allows the label tape of the maximum width to be mounted, that is, the entire width. A pair of guide rolls 7 and 8 installed opposite to the tape guide surface of
A width of approximately 1/2 of the above-mentioned full width, that is, a width shortened from half width to approximately 2/3 of the width, is used.

The shaft 8a of one of the guide rolls 8 protrudes from the main frame 9 in a cantilevered manner over its entire width, and the roll 8 is rotatably supported by the shaft 8a toward the main frame 9 side.

The adjustable frame 13 has a hole that can be fitted into the free end of the shaft 8a of the one guide roll 8, and can be displaced along the shaft 8a through the hole.

On the other hand, the shaft 7a of the other guide roll 7
protrudes in a cantilevered manner from the adjustable frame 13 by approximately half the width to two-thirds of the width, and the roll 7 is rotatably supported on its shaft.

A guide rod 14 is made to protrude in a cantilevered manner from an adjustable frame 13 with a length that can be spanned over a label tape roll mounting shaft 6. The free end 14a of the rod 14 is bent into a hook shape, and the mounting end 14a is fixed to the inside thereof.

Reference numeral 15 denotes a thumbscrew, the tip of which passes through a female screw hole provided in the frame 13 and reaches the side of the shaft 8a, and by tightening the screw, the frame 13 is fixed at a desired position on the shaft 8a. Ru.

The guide device shown in FIG. 2 is used while being fixed at a position for guiding a full-width label tape. In this case, the pair of half-width guide rolls 7 and 8 is such that one guide roll 8 is at the left half-width position, while the other guide roll 7 is at the right half-width position.
In other words, it is in a diagonally different position.

When the thumbscrew 15 is loosened and the adjustable frame 13 is displaced to the left along the axis 8a, the other axis 7a, which is integral with the frame 13, is also displaced to the left, and at the extreme position, both sides are displaced. Guide roll 7
and 8 overlap each other and can guide, for example, a half-width label tape.

As the frame 13 is displaced, the guide rod 14 is also displaced, so that label tapes of different widths can be guided smoothly.

g. Effect of the invention In the present invention, the label tape roll mounting shaft 6 and the tape folded piece 10 are made to have a full width that can guide the label tape 5 of the maximum width, while the pair of guide rolls 7 and 8 are made to have a full width that can guide the label tape 5 of the maximum width. It is made to have a short length, for example, half width to 2/3 width, and furthermore, about half the width of the free end of the roll shaft 8a fixed to the main frame 9 is used as a means for fixing the displacement of the adjustable frame 13. Since the other guide roll 7 and the guide rod 14 are constructed so that they can move as a unit with the displacement of the frame 13, they can be used to handle various types of label tapes ranging from full width to half width. We are now able to guide you reliably and smoothly.

It should be noted that the terms "half width" to "2/3 width" are used as examples, and should not be interpreted in a restrictive manner, as a matter of course from the purpose of the invention.
