DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for printing a belt mark on a belt.

[0002]

2. Description of the Related Art Conventionally, a belt mark of a belt is generally displayed by a thermal transfer method. For example, after attaching a mark sheet on which a belt mark is printed to a sleeve before cutting, the belt mark is applied at a constant temperature. By applying sulfur, a belt on which a belt mark has been transferred has been obtained. However,
A belt having a belt mark displayed by this method has a problem in that noise is generated when the belt is used as a fabelt of an automobile due to the presence of a dent in a portion where the belt mark is transferred. Was.

In order to prevent this problem, as a method of displaying a belt mark that can reduce the depression of a portion where the belt mark is displayed, a method of printing the belt mark on the surface of a belt which has been processed as a belt by an ink jet printer is used. (Japanese Patent Laid-Open No. 7-23899)
No. 2). In this method, a number of belts are arranged on a belt support, the belt is fixed and positioned on the support, and a fixed position of a printer head for ejecting ink and a belt for printing a target character are used. Ink is ejected while moving the support base so as to match a predetermined position. The printing direction for each belt will be described with reference to FIG. (A) schematically shows a state in which belts are arranged on a support table for printing marks. On the support base 55, a number of belts 57 whose length directions coincide with the X direction are arranged in the Y direction. In the setting of the coordinate system, characters and the like are arranged in the belt mark 58 in the positive direction of the X axis. The printer head 56 is fixed, and when the support base 55 moves in the negative direction of the X axis, a belt mark 58 is printed on one belt 57 in the positive direction of the X axis. When printing of the belt mark for one belt is completed, the support 55 moves in the positive direction of the X axis and the negative direction of the Y axis in order to print the belt mark on the next belt 57 '. (B) shows only the movement of the support table. That is, the support table is 51 → 52 → 5
The movement is repeated in the order of 3 → 54, and printing is sequentially performed on all the belts on the support table 55.

However, printing a belt mark by this method has the following problems. That is, in the process of printing the mark, in order to move the support base for each belt including reciprocation for printing, to print on all belts on the support base, The reciprocating motion needs to be repeated many times in proportion to the number of belts. Therefore, when the number of belts is large, it takes a lot of time to print a character group forming a belt mark on all belts. In addition, when the belt length is large or the number of belts is large, the support table for supporting and moving the belt needs to be large, resulting in an increase in the size of the entire apparatus.

Accordingly, an object of the present invention is to provide a belt mark printing method and a printing apparatus which can reduce the time required for printing a belt mark and do not need to enlarge the entire apparatus. I do.

Embodiments of the present invention will be described below with reference to the drawings. First, a printing apparatus used in the method of the present invention will be described, and then a printing method will be described. FIG. 1 is a perspective view illustrating a device configuration of a belt mark printing apparatus. In the figure, the printing apparatus includes a support device A for a cylindrical body, a printing unit B including a printer head and a driving device, and a control device 9.

Next, each part will be described in detail. First, the support device A will be described. The supporting device A has a pair of tension rollers 3a, 7 protruding in a cantilever shape, and supports the tubular body 1 between the tension rollers 3a, 7. The tension roller 7 is rotatably supported by the slide table 10. The slide table 10 can move on the moving bed 8 in the direction of the arrow 11. As a result, the distance between the tension rollers 3a and 7 can be adjusted to match the belt sleeve. This makes it possible to print a clearly displayed mark by applying tension to the cylindrical body 1 and applying appropriate tension to the surface of the cylindrical body 1 from which ink is ejected so as not to bend.

The tension roller 3a includes a rotating motor 3
It is connected to the. The tension roller 3a is driven by the rotation motor 3 to move the cylindrical body 1 around. For example, before the start of a series of steps for printing a belt mark, the motor 3 is driven to move the cylindrical body 1 around, thereby positioning the printing start position on the surface of the cylindrical body 1. The tubular body 1 is an object on which a belt mark is printed by the method of the present invention. Specifically, a belt sleeve before cutting as a belt or a large number of belts after cutting are arranged and arranged. Things apply.

Next, the printing section B will be described. The printing unit B includes a printer head 2 and moving beds 4, 5, and 6 as a driving device thereof. The printer head 2 is disposed toward the outer surface of the tubular body 1 and ejects ink toward the outer surface of the tubular body 1 according to a pattern such as a character representing a belt mark. The printer head 2 operates according to a command from an inkjet printer main body (not shown),
The pattern of the ejected ink is also controlled by the printer body. The ink jet printer main body operates under the control of the control device 9.

The driving device is for moving the printer head 2, and causes the printer head 2 to reciprocate in the width direction and move in the circumferential direction with respect to the cylindrical body 1. Specifically, it is constituted by an X-axis moving bed 5, a Y-axis moving bed 6, and a Z-axis moving bed 4.
In this configuration, the distance between the printer head 2 and the cylindrical body 1 is adjusted by moving the Z-axis moving bed 4. The printer head 2 is moved in the circumferential direction of the cylindrical body 1 by moving the bed 5 for X-axis movement, and the printer head 2 is moved in the width direction of the cylindrical body 1 by moving the bed 6 for Y-axis movement. Can be reciprocated.

That is, in the present invention, the relative movement between the printer head and the cylindrical body necessary for printing the belt mark is performed by fixing the cylindrical body 1 and moving the printer head 2. With such a configuration, even if the belt length is large and, therefore, the cylindrical body 1 is large, a large supporting table for moving the cylindrical body 1 is unnecessary, and it is possible to prevent an increase in the size of the entire apparatus. it can. In addition, since printing is performed by moving the compact printer head 2, the time required for printing the entire tubular body 1 can be reduced.

Next, the control device 9 will be described. The control device 9 controls the operation of devices such as the above-described ink jet printer and a moving bed when performing a series of steps for printing a belt mark. The control device 9 includes an operation unit 9a, and parameters necessary for performing the control operation are set by operating the operation unit 9a. Further, the control device 9 adjusts the operation between the devices for printing the belt mark. In other words, adjustments are made such as when the ink is ejected by the printer head 2 and when the printer head 2 is moved to the position where the ink should be ejected. A pattern such as a character to be printed as a belt mark is stored in a storage unit (not shown) of the control device 9, and is read from the control device 9 to the main body of the inkjet printer as needed. When a pattern such as a character to be printed as a belt mark is newly stored in the storage unit, this is performed by operating the operation unit 9a. The storage unit of the control device 9 stores print conversion means for performing print conversion described later.

Next, an example of a process of printing a belt mark by the method of the present invention using the above-described apparatus will be described with reference to FIG. FIG. 2 (a) shows the cylindrical body 1 according to the method of the present invention.
FIG. 2B shows an example of a state in which a belt mark is printed on a sheet, and FIG. 2B is a comparative example.

The cylindrical body 1 shown in FIG. 2 is formed by arranging a large number of sleeves before cutting or belts after cutting in a row. The belt mark displayed on the belt is composed of a character group of “ABCDEF”. FIG. 2B shows an example in which printing of a belt mark is advanced in correspondence with one belt or a plurality of belts. That is, after printing a belt mark corresponding to each one belt or a plurality of belts, printing a belt mark corresponding to the next one or a plurality of belts, and repeating this. The belt marks for all the belts included in the tubular body 1 are printed.

The step of performing this printing will be specifically described below. Note that, here, for simplicity of description, a case in which a belt mark corresponding to one belt is printed will be described as an example. The printer head and the cylindrical body are relatively moved while printing one character at a time along the circumferential direction 22 of the cylindrical body 1, and printing of one line is completed, and printing of the belt mark corresponding to one belt is completed. I do. When printing for one line is completed, the printer head is moved in the belt width direction 23 with respect to the printer head, and printing corresponding to the next belt is performed. 22a shows the relationship between the direction 22 in which printing of one line proceeds and the arrangement of character strings constituting the belt mark. As described above, if printing is sequentially performed on the tubular body in units of belt marks corresponding to one belt, if the number of belts included in the tubular body increases, every time printing of one line is completed. Since the number of reciprocations of the printer head increases,
This increases the printing time required to complete all printing. Even if printing is carried out collectively for a plurality of belts, there is a limit to reducing the number of reciprocations.

According to the present invention, when printing the character group of the belt mark corresponding to all the belts included in the cylindrical body 1, the character to be printed is reduced so that the number of reciprocating movements of the printer head 2 can be reduced. Is performed. In other words, using the printing direction shown in Comparative Example (b), the printing information “ABCDEF” to be printed in the circumferential direction 22 of the tubular body 1 will be described.
Are arranged in the width direction 23, and print information “AA...”, “BB.
2 and print conversion for output to the printer head 2 is performed.

An example of a process for performing the print conversion will be described with reference to FIG. Printing of all character groups to be printed on the tubular body 1 proceeds in accordance with the character strings arranged on the same line in the width direction of the tubular body 1. In proceeding with printing,
X-axis moving bed 5 and Y-axis moving bed 6 of the device
, The printer head 2 is moved.

In this example, in the coordinate system of the device, the circumferential direction 24 coincides with the X-axis direction, and the width direction 21
Match in the axial direction. The printer head 2 is moved while printing one character at a time along the width direction 21 of the tubular body 1. Each time one character is printed, the Y-axis moving bed 6 is driven to move the printer head 2 in the Y-axis direction. Printer head 2
Starts printing from the position indicated by reference numeral 26 in the figure, and when it moves to the position 26 ', printing of one line ends. Tubular body 1
Are printed along the width direction 21 with characters "AA ...".

Next, the printer head 2 is moved to the position 27 where printing of the next one line is started. Similarly to the above, when the printer head 2 moves to the position 27 ', printing for one line is completed, and the characters "BB ..." are printed on the tubular body 1 along the width direction 21. . In addition, "BB ...
・ ”Is printed on the print head 2 at 26 ′.
27 'and from 27' to 27. With this movement, the time required for the printer head 2 to reciprocate can be reduced. Further, here, the case where the characters are printed one by one along the width direction 21 has been described as an example, but the printing in units of a plurality of characters arranged in the circumferential direction 24 of the tubular body 1 is performed in the width direction 21. The processing can be performed for each of the plurality of rows. For example, if printing is performed two characters at a time, “AA.
・ ・ ”Can be printed at the same time when the upper and lower layers are overlapped. In this case, the width direction 2 of the printer head 2
When the movement to 1 is completed, printing for two lines can be performed. Therefore, the number of reciprocations of the printer head 2 for printing on the entire tubular body 1 can be reduced, and the time required for printing can be further reduced.

When the printer head 2 repeats the reciprocating motion along the width direction 21 and the movement along the circumferential direction 24, a group of characters of belt marks corresponding to all the belts is formed on the cylindrical body 1. Printed. If the reciprocating and moving operations of the printer head 2 are performed in such a combination, the reciprocating operation (the above-described 26 → 26 ′) can be performed even when the number of belts included in the tubular body 1 is large. → 27 →
27 'or 26->26'-> 27 '-> 27), so that the printing time can be prevented from increasing.

Here, the direction 2 in which printing of one line proceeds
21a shows the relationship between 1 and the arrangement of the character strings constituting the belt mark. That is, when printing is performed by the method of the present invention, the direction 2 in which the printer head 2 is reciprocated is
It is necessary to print the characters constituting the belt mark at an angle with respect to 1. In this example, a character pattern forming a belt mark, which is inclined by 90 °, is stored in advance in a storage unit of the control device 9, and when printing on the tubular body 1,
It is configured to be read into the ink jet printer main body and output to the printer head 2.

Next, the printing of the belt mark when the transporting projection is provided on the surface of the tubular body 1 will be described. The protrusion protruding from the surface of the cylindrical body 1 has a flat shape like a typical uneven shape as shown in FIG. 3, and the height of the unevenness greatly affects the printing performance of the ink jet printer. If not, the printer head 2 can be moved and the belt mark can be printed without considering the relationship between the mark printing position and the projection. That is, when the printer head 2 is reciprocated in the width direction 21 and moved in the circumferential direction 24 to advance the printing of the belt mark, the convex portion 26 corresponding to the projection on the surface and the concave portion 2 are formed.
7, the printing of the belt mark including the connection portion 28 can be advanced. Therefore, when the printer head 2 is moved, the movement locus 25
It is not necessary to consider the relationship between the position and the position of the protrusion.

However, the projections formed on the surface of the cylindrical body 1 have a sharpened tip, like the projections 41 and 42 shown in FIG. 4, and affect the printing performance of the ink jet printer. If the mark cannot be determined, it is necessary to consider the relationship with the position of the protrusion.
For example, when the tubular body 1 is intended for a transport belt for a perforated sheet, on the surface of the tubular body 1,
Independent transfer projections are formed in a row in the width direction at a predetermined pitch in the circumferential direction. When the projections formed on the surface of the tubular body 1 are such, it is necessary to take care that the projections do not exist on the movement locus when moving the printer head 2. In this case, the character group is printed in a plane portion between the pitches at which the protrusions are provided so as to extend in the width direction of the tubular body. Also when the printer head 2 is relatively moved in the circumferential direction, the printer head 2 is moved avoiding the position where the projection exists.

Next, in the case where the tubular body 1 on which the character group of the belt mark is printed is a sleeve before cutting, an example of a process of cutting the tubular body 1 to obtain a belt on which the belt mark is displayed is shown. This will be described with reference to FIGS.

Here, a belt having a projection on the surface of a transport belt or the like will be described as an example. 4 indicates one cross section of the belt sleeve 1 in the width direction. On the surface of the belt sleeve 1, a large number of projections 41, 42 and the like are formed at regular intervals. The figure in the drawing indicates that each is cut at the cutting position 38 as a belt. The cutting position 38 is a position corresponding to the center of two adjacent projections 41, 42 and the like. The distance between the adjacent cutting positions 38 corresponds to the width of one belt. FIG. 35 for projection alignment shows an enlarged view of the periphery of the cutting position 38 by about 10 times. One section of actual belt sleeve 4
As for the correspondence between 0 and the enlarged view shown in FIG. 35 for projection alignment, 38 ′ for the cutting position 38, 41 ′ and 42 ′ for the adjacent projections 41 and 42, , 37 correspond to 36 ′, 37 ′.

FIG. 5 shows a step of adjusting the position of the blade provided on the cutter 32 to the cutting position 38 on the belt sleeve 1. The projector 31 includes the belt sleeve 1
This is for confirming the position of the cutter 32 above. The projector 31 has a screen 31a, and the cutter 32 for cutting the belt sleeve 1 is enlarged so that the cutter 32 can be monitored on the screen 31a. A cross line is displayed on the screen 31a, and the cutter 32 can be positioned with reference to the cross line. Since the cutting position is adjusted to the position where the cross hairs cross, the cutter 32
The position of the cutter 32 is adjusted so that the cutting edge of the cutter looks like a crossing point. The positioning of the cutting position 38 is performed by using the above-described projection alignment drawing 35. By attaching the projection alignment drawing 35 to the screen 31a of the projector 31, the position of the cutter 32 is confirmed. . The belt sleeve 1 is cut by inserting the belt sleeve 1 into the main shaft 33,
Is turned to fix the belt sleeve 1.

In the printing method according to the present invention, if a predetermined print conversion is performed and printing is performed while moving the printer head, the tubular body on which the belt mark is to be printed is a belt sleeve before cutting. And the case where a large number of cut belts are arranged and printed. In the description herein, the support device is configured to protrude in the Y direction. However, the present invention is not limited to this. Any device may be used as long as it can fix the cylindrical body so that the belt mark can be printed clearly.
