Description

[Detailed description of the invention] This invention is a continuous tack paper in which the front surface is printed continuously at predetermined intervals, and an adhesive layer is formed on the back side of the base paper and attached to a release paper (mounting paper). The present invention relates to a label processing machine that cuts a score line along the circumference of each individual label to the upper surface of a release paper while transporting tack paper.

Conventionally, for continuous tack paper with a double structure in which a label with an adhesive layer is removably attached to the surface of release paper (mounting paper), the processing machine that encloses the printed figure on the label and makes score lines is The tack paper is intermittently transferred between the board and the top board which can move upwards and downwards, and when this stops, the top board equipped with a pushing blade is pressed down to form a score line around the label. In this method, the transport of the tack paper is interrupted intermittently to perform the cutting operation, so it takes time to create the cut lines on the label.
It was inefficient.

For this reason, we have developed a method in which the tack paper is continuously transported, and during this transport, the upper plate equipped with a push-cutting blade is instantly pressed down by the action of a rotating eccentric (cam) to form a score line around the label. was developed.

However, in this method, the downward pressure of the pushing cutting blade is momentarily suppressed by the convex arc of the long diameter part of the eccentric ring, so the average horizontal pressure of each part is not applied to the upper plate, and moreover, the lower pressure of the eccentric ring is The lower part of the upper plate moves horizontally while pressing against the bottom, causing vibrations and rattles.

Therefore, it is possible to increase the range of the total length of the cutting blade and the blade length by equipping the lower surface of the upper panel with label pressing blades over a wide area or by equipping multiple pressing blades so that many small labels can be cut at the same time. , it is not possible to apply an average horizontal pressing force to the entire area of the pressing cutting blade of the upper plate only by point suppression of the protruding arc by the eccentric wheel.

For this reason, the release paper on the bottom surface of the label base paper may be cut, or there may be areas where the full heat cut is not made, resulting in uneven cuts and defective products.

Further, when the thickness of the label is less than 0.1 mm, there is a drawback that it is not possible to perform beautiful and efficient cutting on the overall average.

The purpose of the present invention is to eliminate such drawbacks and to enable highly efficient label score line processing.The present invention will be explained below based on the drawings.

In Figures 1 to 3, 1 is the main body of the label processing machine, 2 is the machine frame on both sides, and 3 is a label base paper 4 with labels printed intermittently on its surface, and an adhesive layer 5 coated on its back surface. Continuous tack paper with a double structure on which a continuous release paper (mounting paper) 6 is pasted, 1 and 8 are feed rolls and guide rolls of tack paper, 9
1 is a take-up roll, and 10 and 11 are an upper plate and a lower plate installed oppositely above and below the continuous transport path of the tack paper 3.

The lower plate 11 is installed to be able to reciprocate horizontally back and forth along two rails 12.12 on the left and right installed on the processing machine main body 1, and has left and right rails on its upper surface that serve as supporting surfaces for the tack paper. It is equipped with a base plate 13 whose movement can be adjusted freely and pillars 14 erected at the four corners.

The upper board 10 is provided with four pillars 14 and a support board 13 between the guide board 15 attached to the upper end of the upright pillars 14 at the four corners of the lower board 11 and the base board 13 of the lower board 11. It is held horizontally by a spring 16 so as to be able to move up and down.

Further, the lowering shaft 17 erected in the center of the upper surface of the upper plate 10 protrudes upward through the shaft guide 15' of the guide plate 15, and a rolling bearing 18 is supported by providing a bearing metal 17' at the upper end thereof. It's a shame.

The lower surface of the upper board 10 is provided with a blade mounting base board 20 having a push-cutting blade 19 for cutting the tack paper 3 along the circumference of a single label and having a horizontal position adjustable.

21, 22, and 23 are a rotating shaft and first and second crankshafts that are mounted parallel to each other across the left and right machine frames 2, 2 above the rotational repair ring 18; 22.2
Eccentric wheels 24 and 25 are formed in the center of 3.

Across these eccentric wheels 24 and 25, bearings 24a and 25
A crank metal 28, which is provided with holes 26 and 27 that are fitted through holes 26 and 27 and whose lower surface is formed horizontally, is fitted and mounted as shown in FIGS. 2 and 3.

Reference numeral 29 denotes a horizontal pressure guide having a protrusion 30 at the rear end and a front downward inclined guiding surface 31 for pressing down the rolling repair ring 18 against the spring 16 on the lower surface, and the front part thereof is made of crank metal. A branch 32 hanging from the center of 28,
By means of an adjustment bolt 34 and an adjustment nut 35 which are pivoted between 32 and 32 with a pivot 33 and screwed onto the rear part of the crank metal 28, the inclined guiding surface 3 is rotated with the pivot 33 as a fulcrum via the protrusion 30.
It is provided so that the forward downward slope of No. 1 can be freely adjusted.

36, :H is a gear attached to one end of the first and second crankshafts 22, 23; 38 is an intermediate gear pivotally supported on one side of the machine frame 2 so as to mesh with gears 36 and 37; 39 is a gear 36; 40 is a transmission shaft for rotating the rotation shaft 21; 41 is a transmission box;
Reference numeral 2 denotes a mechanism for horizontally reciprocating the lower plate 11 and the upper plate 10 back and forth at the transfer speed of the tack paper 3, which includes an arm 45 projecting from one end of the bell crank 44 of the bell crank shaft 43 and below the lower plate 11. A connecting rod 48 connected to the other end of the bell crank 44 and a stacking rod 41 which can be appropriately given swinging motion by a transmission shaft 40 are connected.

In the figure, 49 is a winding shaft for waste paper after the score line is completed.

The present invention has the above-mentioned configuration, and the tack paper 3 is advanced at a predetermined transfer speed by the feed roll 7 and the guide roll 8 in the direction of the arrow shown in FIG.

At this time, the bell crank shaft 43 of the lower plate 11 rotates back and forth from the transmission shaft 40 via the stacking rod 47, and further, the lower plate 11 moves along the rails 12, 12 via the connecting rod 46 and the arm 45 to roll the tack paper. It is horizontally reciprocated back and forth at the transfer speed, and 4
The upper plate 10 and the guide plate 15 are also reciprocated together via the corner supports 14.

Thus, when the upper and lower plates 10 and 11 move forward at the same speed as the transfer speed of the tack paper 3, the first and second cranks are rotated by the gear 39 of the rotating shaft 21 via the gears 36, 38, and 37. Crank metal 28 fitted to eccentric wheels 24 and 25 of shafts 22 and 23 via repair rings 24a and 25a.
As the long diameter part of the eccentric ring 24°26 rotates downward, it is lowered horizontally, and the horizontal pressure guide 29, which is supported by a pivot 33, also lowers, and the inclined guide surface 31 rotates the repair ring. 18 is pressed downward, and the upper plate 10 is lowered horizontally together with the lowering shaft 17 during forward movement, and the pushing cutting blade 19 equipped thereon is lowered.
moves forward at the speed of the tack paper 3 being transported and pushes the edge of the single label on the label base paper 4, pressing it into the upper surface of the release paper 6 as shown in FIG.

Next, the eccentric wheels 24 of the first and second crankshafts 22,23,
Since the horizontal pressure guide 29 that presses down the rolling repair ring 18 has an inclined guiding surface 31 even when the long diameter portion of the bearing 18 rotates upward from the lowest position, the bearing 18 rolls along this inclined guiding surface 31. Moves forward horizontally, so the upper board 10
The push-cutting blade 19 provided on the base paper 4 is kept pressed down on the label paper 4 while maintaining an overall average horizontal pressure state, and even if the blade has a long overall length and a wide range, each part of the square-shaped push-cutting blade 19 can be The label base paper 4 is cut to the upper surface of the release paper 6 by applying horizontal pressure in close contact with each other, and a score line is formed surrounding the printed area of the single label a.

When the rolling repair ring 18 thus reaches the front end of the inclined guide surface 31 of the horizontal pressure guide 29, the long diameter portions of the eccentric wheels 24°25 of the first and second crankshafts 22.23 rotate to a higher position. Therefore, the crank metal 28 and the horizontal pressure guide 29 also rise, and the upper plate 10 rises due to the force of the spring 16, and the pushing cutting blade 19 moves away from the label paper 4 surface, and as the lower plate 11 moves backward. The upper board 10 is also moved back, and the same operation as described above is repeated intermittently at the transport speed of the tack paper 3 to surround and cut the printed portion of each individual label on the label base paper on the upper surface without stopping the tack paper 3. Lines are automatically processed.

The tack paper 3 that has been processed with the cut lines is wound up on a take-up roll 9, and the waste paper C around the cut label is taken up on a take-up shaft 49 installed in the machine body. , only a single label a cut to a certain size is intermittently formed on the continuous release paper 6 of the tack paper 3 and sent to be wound up on the winding shaft 9. It is.

The above explanation is based on the case where one label a is cut and formed at a time by the push-cutting blade 19, but as shown in FIG. When making cuts, by attaching a large number of push-cutting blades shaped to surround the periphery of each label to the blade mounting board 20 of the upper plate 10, the crank metal 28, horizontal When the upper plate 10 is pressed down through the pressure guide 29, the rolling repair ring 18, and the rolling down shaft 17, the pushing cutting blades in general are pressed against the rolling bearing 1 as in the previous case.
8 and the inclined guiding surface 31 of the horizontal pressure guide, the base paper is brought into close contact with the base paper and horizontal pressure is applied at regular intervals, and the periphery of each label b is cut by the same horizontal pressure as described above, and a large number of labels are cut at the same time. It can be cut into.

The present invention has the above-mentioned configuration, in which the upper plate equipped with a push-cutting blade and the lower plate supporting the paper surface are reciprocated back and forth at the transport speed of continuous tack paper, and when the upper plate and the lower plate move forward, the upper plate The rotation repair ring installed at the upper end of the reduction shaft is fitted across both eccentric wheels of the two crankshafts, and the eccentric circular movement of the crank metal, and the inclined guide surface of the horizontal pressure guide pivoted at the bottom of the metal. At the same time, when the long diameter part of the eccentric wheel rotates upward from the lower part, the rolling bearing is temporarily moved by the inclined guiding surface to keep the upper plate in a horizontally pressurized state for a fixed period of time. Because it is designed to maintain pressure, unlike the conventional method of momentary point pressure using the protruding arc of an eccentric wheel (cam), the pushing cutting blade installed on the upper panel sticks to the paper surface and maintains the downward pressure state for a fixed period of time. Since it is pressed, even if the range of the pressing cutting blade is wide and the overall length of the blade is long, it is possible to cut into the shape of a peelable and stickable label with the force applied to each part along the circumference of the label.

In addition, since the lowering shaft of the upper plate is not bent by the eccentric wheel (cam), it is possible to eliminate the rattling and wobbling of the pressing cutting blade, which prevents the release paper (backing paper) on the bottom surface from being cut or poor cutting around the label. There is no risk of parts being formed, and the label can be cut accurately and beautifully at a relative speed of zero that is synchronized with the transport speed of the label base paper.

Furthermore, as the eccentric wheel's major axis rotates upward above a certain level, the upper plate is raised and retreated, and the above operation is repeated at the tack paper transport speed, so that the tack paper can be continuously labeled without stopping. It is possible to cut the mold, and the label molding process can be performed automatically with great ease and high efficiency.

In addition, the degree of horizontal pressure for press-cutting around the label can be easily adjusted by advancing and retracting the adjustment bolt and adjusting the degree of inclination of the inclined guide surface on the bottom surface of the horizontal pressure guide. It is something that you have.
