Description

[Detailed description of the invention] This invention relates to an improvement of a sample printing machine used for sample taking or color matching.

The sample printing machine uses an engraved roll that forms an intaglio pattern.
A simple textile printing machine that can be used on a trial basis before being installed in the printing machine for the actual process to check the color tone depending on the state of the size liquid for this roll, the finished state of the roll face, pattern matching in the case of multicolor dyeing, etc. It is.

In order to facilitate the frequent replacement of engraving rolls in such sample printing machines, the inventor of the present invention has proposed that the bearings be surface-supported by a pair of support rollers at both ends, and provided on these rollers. A support mechanism was devised in which movement in the axial direction was prevented by a collar, and the engraving roll could be easily operated by simply placing it on a pair of support rollers.

The present invention is intended to provide a mechanism for facilitating the glue adhesion confirmation operation, particularly in the above-mentioned engraving roll support method.

That is, in a textile printing machine, before the fabric is hung on a drum and operated, the state of adhesion of size liquid to the engraving roll is first checked, and the same is true for sample printing machines.

This confirmation operation is performed by pressing the engraving roll, which does not have its own driving means, against the drum in a conventional textile printing machine (the bearing of the engraving roll includes both a supporting method and a surface supporting method using a pair of rollers), and By manually rotating the drum while holding the fabric, the engraving roll is driven together with the fabric, and the circumferential surface of the engraving roll, which has passed through the size liquid supply angular position and reached the angular position just before contacting the fabric, is rotated by hand. This was done through observation.

However, this method requires a large amount of human power to manually operate the pressure transmission system consisting of the drum, fabric, and engraving roll.Moreover, the fabric to be driven by pressure is moved from the size liquid supply position to the position just before the position where it contacts the fabric on the engraving roll. The disadvantage is that the length corresponding to the rotation angle up to is wasted.

This drawback is that green areas are removed in proportion to the number of colors (number of engraving rolls) in one sampling, and there has been a desire to improve this problem.

The present invention was constructed in response to the above-mentioned demands, and is a sample printing printing method in which an engraved roll having a coaxial hole opened at least on one end surface is supported on the surface by a pair of support rollers with the opening completely exposed. The machine includes a jacket adapter inserted into the opening to transmit rotation to the engraving roll, and a manual jacket that engages with the adapter to rotate the engraving roll only in the forward direction. This is a characteristic feature.

Preferred embodiments will be described below with reference to the drawings.

In FIG. 1, 1 is a drum, 2 is an engraving roll that pinches the fabric and comes into pressure contact with the drum 1, 4 is a size liquid supply mechanism that is in contact with the engraving roll 2, and 5 and 6 are a pair of rollers that support one end of the engraving roll 2. A pair of similar rollers for supporting the other end is also arranged behind these.

The pair of rollers 5 and 6 are supported by a frame 7, and by changing the position of this frame 7, the engraving roll 2 can be moved to the fabric clamping position shown in FIG. It shall be maintained either.

The horizontal and vertical positions of the frame 7 are set on a frame holder generally indicated by a phantom line 8 .

A calendar roll 9 is disposed on the upper circumferential surface of the drum 1, and a flank roll 10 is disposed on the lower left circumferential surface of the drum 1, and the drum 1 is rotationally driven clockwise in the figure by a drive source 11 consisting of a motor and a transmission mechanism. Then, the fabric 3 passes through the pressure gap between the calender roll 9 and the drum 1, bypasses the drum circumferential surface, comes into pressure contact with the engraving roll 2 on which the size liquid from the size liquid supply mechanism 4 is attached, and then passes through the flank roll 10. It is something that can be drawn out.

Note that there are, for example, six pin holes 12 on the end surface of the drum 1.
is formed, and when a pin is inserted into one of these pin holes 12a through a pin guide (not shown) fixed at a fixed position as shown by the dashed line A-A in the figure, the driving source 11 is disabled.

In the case of multi-color dyeing, this mechanism regulates the end position of the drum's reverse rotation to return the fabric printed in the previous color to its starting point in response to the engraving roll that is replaced for each color, and also controls the end position of the drum's reverse rotation. This prevents the drum 1 from being driven while it is still in place.

Note that this reverse rotation can be easily manually operated if a one-way bearing (non-return bearing) is interposed in the transmission mechanism of the drive source 11.

As is clear from FIG. 1, the engraving roll 2 has a through-hole concentric hole 1.
Preferably, the inner surface of the concentric hole 13 is formed with a protrusion 14 extending in the axial direction.

The pair of support rollers 5 and 6 has a flange 15 (Fig. 3) that locks the end face of the roll 2, but the engagement dimension in the diametrical direction is small, and the concentric holes 13 are formed on the end face of the roll in Fig. 1. fully exposed.

According to the invention, a jacket adapter is used for inserting into the concentric hole 13 from the end face of FIG. 1 in the fabric release position of the engraving roll 2.

Figure 2 shows the jacket adapter 16 and 17.
18 is a main body portion to be fitted into the concentric hole 13, and 18 is a slot formed in the main body portion, which engages with the protrusion 14 of the concentric hole 13 to prevent relative rotation between the engraving roll 2 and the adapter 16. It is something.

The adapter 16 also has a flange 19, which restricts the insertion position into the concentric hole 13.
A prism 20 for locking the jacket is protruded from the center of the front of the flange 19.

FIG. 3 is a schematic diagram showing the adapter 16 inserted into the engraving roll 2 in the fabric release position, and the adapter 1
The engagement hole of the jacket 21 is applied to the prism 20 of No.6.

As shown in FIG. 4, the jacket 21 has a rotating portion 23 having an engagement hole 22 at its base supported by a one-way bearing or a ratchet.

Therefore, by operating the handle 24, this rotating part can be rotated counterclockwise in the figure, but when there is a retaining load, the handle 24
Even if 4 is returned clockwise, it cannot be rotated in the same direction.

Note that, in addition to the jacket shown in the drawings, jackets having other suitable structures can be used.

Therefore, the operator easily rotates the engraving roll 2, which is in a position slightly separated from the drum 1 and released from the fabric, in the counterclockwise direction in FIG. By monitoring the circumferential surface of the engraving roll 2 exposed between it and the roller 6, it is possible to easily check the state of adhesion of the glue to this surface.
