Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a print sheet mounting device that has an improved mounting means for a print sheet wrapping body of a thermal printing device or the like.

[Conventional technology]

In a conventional thermal printing device of this type, after a sheet wrapping body wrapped with a printing sheet is rotatably mounted, a feeding roller (not shown) is used.
The printing sheet is fed out from the printing sheet wrapped around a sheet supply roller using a roller and supplied to the printing section of the thermal head, where the label is affixed to the printing sheet itself or to the surface of the long substrate using voltage or heating means. The content is printed on the label and sent out.

FIG. 4 is a diagram showing the configuration of a conventional printed sheet winding device equipped with the sheet winding body described above. That is,
This device consists of a sheet wrapping body 3 in which a printing sheet is wrapped around a rotating shaft 2 protruding from one side of a substrate 1.
is installed. In the figure, 4 is an inner guide plate, 5 is an inner boss fixed to the center of the inner guide plate 4, 6 is a push screw for fixing the boss, 7 is an outer boss, 8 is a push screw for fixing the boss, and 9 is an outer boss. A magnet 7 is attached to the right end surface, and 10 is an outer guide plate that is fixed to the magnet 9 by adsorption.

Therefore, when mounting sheet wrapping bodies 3 of different widths, this printed sheet mounting device removes the outer guide plate 10 and loosens the push screws 6 and 8, and then
The center position A is determined by measuring a predetermined dimension a from the substrate 1, and both guide plates 4, 10 are placed at a position equidistant from the center position A and corresponding to the width of the sheet wrapping body 3. In order to set this, measure the respective distances from the board 1, move the bosses 5 and 7 in the direction shown in the figure to the corresponding positions where the guide plates 4 and 10 should be located, and then set the push screws. Both bosses 5 and 7 are fixed to the rotating shaft 2 by screwing in the bosses 6 and 8.

Another conventional printed sheet mounting device is the fourth
It has almost the same configuration as shown in the figure, except that instead of the structure in which the outer guide plate 10 is attracted to the magnet 9, a screw of a predetermined length protrudes from the right side of the outer boss 7 as shown in the figure, and is compatible with this screw. The outer guide plate 10 is inserted through the hole formed at the position where the
The outer guide plate 10 is fixed to the outer boss 7 by inserting a wing nut into the screw protruding outward through the outer guide plate 10. Note that the term "printed sheet" here refers to a sheet used in printers and other general recording devices, and also refers to sheets in which labels are pasted at predetermined intervals on a long substrate and the printed contents are printed on the labels. It includes.

[The problem that the invention attempts to solve]

However, the former magnetic adsorption type
When replacing sheet wrapping bodies 3 of different widths, measure a predetermined dimension a from the board 1 to determine the center position a, and measure the dimension a obtained by determining the center position a. After determining the distance b from the substrate 1 to the inner guide plate 4 based on It is necessary to measure the length corresponding to the width of the body 3 and set the right end position of the outer boss 7 including the magnet 9. For this, it is necessary to prepare the scale, measure the length, and set the push screw 6, 8 screws are required, making the sheet installation work extremely troublesome.
In addition, the work of determining the center position A requires experience and requires great care; if the center position A is deviated, the printed sheet unwound from the sheet wrapping body 3 may be skewed or twisted. This will prevent proper printing. Furthermore, if the bosses 5 and 7 are repeatedly fixed using the push screws 6 and 8, the rotating shaft 2
There is a problem in that many unevennesses occur in the push screws, and the tips of the push screws 6 and 8 shift when they are pushed in, making it impossible to accurately index the center position.

On the other hand, the latter type using a butterfly nut is
Needless to say, it has the same drawbacks as the former. Therefore, both types described above cannot be said to be suitable for mounting sheet wrapping bodies 3 having different widths.

The present invention has been made in view of the above circumstances, and allows for accurate indexing of the center position without the need for tool preparation or length measurement work, and allows sheet wrapping bodies of different widths to be easily and easily arranged. It is an object of the present invention to provide a printing sheet mounting device that can be mounted quickly.

[Means for solving problems]

Therefore, according to the printed sheet loading device of the present invention, the right guide member and the left guide member, which are erected so as to press the both side surfaces of the sheet wrapping body around which the printed sheet is wound, are individually inserted from the bottom side of each of the right guide member and the left guide member. The sheet winding is performed between a pair of adjustment plates extending in the direction opposite to the sheet winding body and provided one after the other in the feeding direction of the printed sheet wound around the sheet winding body, and the left and right guide members. It is rotatably supported at approximately the center position of the width of the body, and its both end sides are engaged with elongated holes formed in each adjustment plate to the left and right with the center position line as a boundary, and the sheet winding An interlocking lever that rotates to move the pair of adjusting plates left and right according to the width of the body, and an interlocking lever that is attached to be movable up and down and arranged so that its lower end abuts the upper edge of the adjusting plate. With the stopper that was done;
and a pressing body that presses down the upper end of the stopper to prevent movement of the adjustment plate, and when the sheet wrapping body is installed, the pressing of the stopper by the pressing body is released and the interlocking lever is rotated. The distance between the left and right guide members is adjusted according to the width of the sheet wrapping body.

[Effect]

Therefore, by taking the above measures,
When loading sheet wrapping bodies of the same or different widths, for example, use the printer unit itself or other components as a pressing body, lift this pressing body to release the stopper from moving it to the adjustment plate, and then unload the sheet wrapping. By rotating the interlocking lever according to the width of the sheet wrapping, the left and right guide members move left and right with respect to the center position, and the distance between the two guide members is adjusted appropriately. can be installed reliably and easily, and the movement of the adjustment plate is immediately stopped simply by placing the pressing body on the stopper, allowing an appropriate interval to be maintained over a long period of time.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1 is a partially cutaway plan view, FIG. 2 is a view seen from the direction of arrow A in FIG. 1, and FIG. 3 is a view taken along line BB shown in FIG. In these figures, 21a and 21b are a right frame and a left frame that are erected at a predetermined interval, and a substrate 22 is installed from, for example, the middle part of these frames 21a and 21b, spanning over each frame 21a and 21b. It is being constructed. This board 2
2, a right guide member 23a and a left guide member 23b are erected at an appropriate interval while maintaining a state parallel to the frames 21a, 21b. A pair of adjusting plates 24 ₁ , 24 ₂ are installed one after the other in the direction in which the print sheet wound around the sheet wrapping body is fed out and individually extends in opposite directions. The opposite direction is the right guide member 23
This means that the adjustment plate 24 ₁ extends to the left from a, and the adjustment plate 24 ₂ extends to the right from the left guide member 23b. The pair of adjusting plates 24 ₁ , 24 ₂ are positionally regulated by guide pressers 25 ₁ , 25 ₂ which block movement in the sheet feeding direction and also serve as guides for the adjusting plates 24 ₁ , 24 ₂ .

Reference numeral 26 denotes an adjustment plate position regulating member disposed between the pair of adjustment plates 24 ₁ and 24 ₂ in a direction perpendicular to the sheet feeding direction, and both ends thereof are screwed to the base plate 22 with screws. In this adjustment plate position regulating member 26, a support shaft 27 is provided at approximately the center position of the width of the sheet wrapping body, and an interlocking lever 28 is rotatably attached to this support shaft 27.
Further, elongated holes 29 1 , 29 ₂ are formed on the left and right sides of each adjustment plate _{24 1} , 24 ₂ with a line extending from the support shaft 27 in the sheet feeding direction as a boundary;
Each end of the interlocking lever 28 is engaged with these elongated holes 29 ₁ and 29 ₂ . Therefore, if the interlocking lever 28 is rotated in the direction of the arrow in the figure, the pair of adjustment plates 24 are moved using the adjustment plate position regulating member 26 as a guide.
₁ , 24 ₂ are designed to move in the left and right direction.

Reference numeral 30 is, for example, an L that is engaged with an engagement member 31 on the inner wall of the right frame 21a and is movable up and down.
It is a letter-shaped stopper, and the lower end side of this stopper 30 is arranged so as to be parallel to the end of the adjustment plate ₂₄₂ (the end opposite to the guide member 23b) with a predetermined distance, A movable sealing member 32 made of rubber or the like is fixed to the lower side of this parallel flat portion. Reference numeral 33 is a pressing body such as a printer unit, for example, as shown in FIG.
The bottom part of the stopper 30 is brought into contact with the upper end part of the stopper 30,
Further, when the pressing body 33 is rotated about the support shaft 34 in the direction of the arrow D in the figure and lifted, the pressing body 33 is separated from the upper end of the stopper 30. 35, 36 are seat bearing shafts, 37
38 is the printed sheet, 38 is the sheet wrapping body in which the printed sheet 37 is wrapped, and 38a is the maximum diameter,
38b indicates the minimum diameter.

Therefore, according to the printed sheet mounting device as described above, when the stopper 30 is pressed downward by the pressing body 33, the lower end flat portion of the stopper 30 is moved through the movable sealing member 32. Adjustment plate 24 ₂
Since the pair of adjusting plates 24 ₁ , 2
4 ₂ movement is blocked, and both guide members 23a, 2
3b is maintained at the desired spacing.

When mounting sheet wrapping bodies 38 of the same width or different widths in the above state, the support shaft 34
When the pressing body 33 is rotated around , the bottom surface of the pressing body separates from the upper end of the stopper 30, and the stopper 30 becomes vertically movable, and the pair of adjustment plates 24 ₁ and 24 ₂ are freely moved. It becomes possible to move. Therefore, after taking out the sheet wrapping body 38 that has already been installed, the left and right guide members 23
When the distance between a and 23b is varied, the interlocking lever 28 is rotated accordingly, and the pair of adjusting plates 24 ₁ and 24 ₂ are moved to the left and right, with the support shaft 27 being the center. Here, the left and right guide members 23a, 23b
When the interval corresponds to the width of the sheet wrapping body 38, the rotation of the interlocking lever 28 is stopped at that position and the sheet wrapping body 38 is attached, and then the pressing body 33 is lowered and the stopper 30 , and prevents movement of the pair of adjusting plates 24 ₁ and 24 ₂ .

Therefore, according to the configuration of the embodiment as described above,
By rotating the interlocking lever 28 according to the width of the sheet wrapping body 38, the pair of adjustment plates 24 ₁ and 24 ₂ are moved to the left and right around the support shaft 27, so distance measurement can be performed. The center position can be accurately determined without any problems. In addition, in the case of a device whose movement is sealed by operating a push screw, if the screw is not tightened loosely, the position will shift, and if it is too tightened it will leave marks on the receiving shaft, and if this is repeated, the marks on the receiving shaft will cause the push screw to shift. The tip of the screw would shift and cause a similar positional shift, but in this device, the movement of the pair of adjustment plates 24 ₁ and 24 ₂ is blocked by the pressing body 33 and the stopper 30, and the interlocking lever 28 is rotated. A pair of adjustment plates 24 ₁ , 2 unless
Since the 4 ₂ does not move, it is possible to set the desired spacing over a long period of time. In addition, since the pair of adjustment plates 24 ₁ and 24 ₂ are moved in conjunction with the lever 28, the left and right guide members 24 2 are moved from the center position.
3a and 23b can be set quickly and always at the same distance.

In the above embodiment, a printer unit is used as the pressing body 33, but any structural member may be used as long as it has a similar function. Moreover, although the pressing body 33 is placed directly on the upper end of the stopper 30, the stopper 30 may be pressed down via a lever or the like (not shown). In addition, although the movable sealing member 32 is provided at the lower end of the stopper 30 to prevent movement of the adjustment plate 24 ₂ , it is possible to prevent the adjustment plate 24 ₂ from moving by forming unevenness on the facing portion of the stopper 30 and the adjustment plate 24 2 . The sealing member 32 is not necessarily required. Also,
Although the interlocking lever 28 was provided to rotate directly,
A connecting arm, a rotation transmitting mechanism, etc. (not shown) are connected to the interlocking lever 28, and these connecting arms, rotation transmitting mechanism, etc. are connected to the substrate 22 and the frame 21.
The distance between the left and right guide members 23a and 23b can also be adjusted by extending the guide members a and 21b to the outside along their respective surfaces and operating them from the outside.
Furthermore, connecting arms (not shown) may be connected to the guide member 23a or 23b, and these connecting arms may be extended to the outside along the solenoid surfaces of the frames 21a and 21b. In addition, the present invention can be modified and implemented in various ways without changing the gist thereof.
