Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device for gluing the edges of knit fabric in a tenter.

(Prior art) When printing a long knitted fabric, in order to prevent the edges of the knitted fabric from curling, it is necessary to apply glue to the edges of the knitted fabric using a tenter in the heat setting process that precedes the printing process. The gluing apparatus shown in FIGS. 2 and 3 is used for such gluing.

In Fig. 2, F is a knitted fabric, 1 is an entrance frame, 2 is a pair of left and right tenter rails, and 3 is a heat treatment chamber. The substrate F is conveyed to the heat treatment chamber 3 with its ears held by pins of left and right tenter chains 4 (see FIG. 3) running along the tenter rail 2. A glue box 5 is provided below the inside of the tenter chain 4 at the entrance of the heat treatment chamber 3, and a glue roller 6 is provided in the glue box 5 so as to be in contact with the lower surface of the selvedge of the knit fabric F. The roller 7 comes into pressure contact. Then, the tenter rail 2 is attached to the bottom of the glue box 5.
The lower part of tank receiver 8 located on the side of The glue S in the glue box 5 is conveyed upward by the rotation of the glue roller 6 and transferred onto the lower surface of the knit fabric F.

(Problem to be Solved by the Invention) However, in the above conventional device, when the size liquid S in the glue box 5 is consumed and the size liquid level in the tank receiver 8 becomes lower than the opening end of the nozzle 11, the nozzle 11
Air enters the glue tank 10, and the glue S in the glue tank 10 descends by that amount, keeping the glue level in the glue box 5 and tank receiver 8 at a predetermined level, and when the glue tank 10 is empty, This glue tank 10 is
It is intended to replace the glue tank 10 containing the
Because this glue tank 10 is made to have a small capacity due to its mechanism, it is necessary to replace it frequently, so the presence or absence of the glue S in the glue tank 10 must be constantly monitored, and when the glue S runs out, it should be promptly replaced. It was necessary to replace the glue tank 10. In addition, since the above-mentioned size liquid tank 10 has the nozzle 11 facing downward, the size liquid S spills downward during the above-mentioned exchange, and the heat treatment chamber 3
There was a problem with the area near the entrance becoming dirty.

This device can maintain the glue level in the glue box at a desired level, automatically supply glue to the glue tank, and increase the capacity of the glue tank to reduce the number of refills. To provide a gluing device which can be used without spilling glue liquid.

(Means for Solving the Problems) In order to solve the above problems, in this invention, the tenter is attached to the lower surface of the edge of the knit fabric held between the left and right tenter chains on the left and right sides of the entrance to the heat treatment chamber of the tenter. In a device for gluing the edges of knit fabric in a tenter, which is provided with a gluing roller that contacts the inside of the chain and a glue box for immersing the lower part of the gluing roller in a glue liquid, the gluing device is installed at the bottom of the glue box and on the side of the tenter. The lower part of the glue tank is connected with a glue supply pipe, a pump and a flow rate control valve are sequentially installed on the glue tank side of this glue supply pipe, and a circulation pipe is connected upward to the glue box side of this flow rate control valve,
The upper part of this circulation pipe is bent sideways at the height of the desired size solution level in the glue box, and the tip is opened at the top of the glue tank.

(Function) When the opening of the flow rate control valve is appropriately adjusted and the pump is driven, the size liquid in the glue tank is sent to the glue box via the glue supply pipe, and some of the size liquid is sent through the circulation pipe. Returned to the glue tank, the glue liquid level in the glue box is controlled to the level of the upper end of the circulation pipe. Therefore, by setting the height of the upper bent portion of the circulation pipe to a desired size liquid level, the size liquid level can be maintained at a desired height. The glue tank is replenished with glue liquid from above at any time.

(Example) In FIG. 1, support arms 21 protrude inward from the lower sides of the left and right tenter rails 2.
A glue box 22 is fixed to the tip of the glue box 22, a glue roller 23 is rotatably attached to the glue box 22, and a presser roller 24 is pressed against the upper surface of the glue roller 23.

A glue tank 25 is placed on the side of the tenterail 21 above.
is installed, one end of a horizontally extending glue supply pipe 26 is connected to its bottom, and the other end and the intermediate branch are connected to the bottoms of the left and right glue boxes 22 via flexible pipes 27, respectively. . A pump 2 is provided on the glue tank 25 side of the glue supply pipe 26.
8 and a flow control valve 29 are interposed in series, and a circulation pipe 30 and a drain pipe 32 are connected in this order to the glue box 22 side of the flow control valve 29. The circulation pipe 30 has an upward vertical portion 30a and a horizontal portion 30 extending horizontally from its upper end toward the glue tank 25 side.
The vertical portion 30a is divided into upper and lower halves, and the separated portions are telescopically connected with a level adjustment pipe 31, so that the height of the horizontal portion 30b can be adjusted. The tip of the horizontal portion 30b is opened onto the glue tank 25. Further, a drain pipe 32 is connected adjacent to the circulation pipe 30, and a drain pot 33 is attached to the drain pipe 32.

In the above structure, the size liquid S is stored in the size liquid tank 25.
, close the drain pot 32, and close the flow control valve 29.
When the pump 28 is driven by adjusting the opening degree of the pump 28 and the height of the horizontal portion 30b of the circulation pipe 30,
The glue liquid level in the glue box 22 is controlled to the height of the above-mentioned horizontal portion 30b. Then, when the left and right tenter rails 2 move left and right in accordance with the fluctuation of the width of the knitted fabric F and the distance between them is adjusted, the glue box 22 and the glue The flexible pipes 27 between the supply pipes 26 are respectively displaced.

(Effect of the invention) This invention connects the lower part of the glue box and the lower part of the glue tank installed on the side of the tenter with a glue supply pipe.
A circulation pipe branching from this glue supply pipe is bent upward from the height of the glue box to the glue tank side, its tip is opened above the glue tank, and the glue liquid from the glue tank is sent to the glue box using a pump. Since the glue is simultaneously circulated to the glue tank, the glue liquid level in the glue box can be automatically maintained at a desired level. In addition, the glue tank can be filled with glue liquid from above, and there is no need to replace or move the glue tank like in conventional glue tanks (see Figure 3), which reduces the capacity of the glue tank. It can be made large enough to hold the amount used for one day, eliminating the need for intermediate replenishment, making it easier to replenish the size liquid to the glue tank, and eliminating the risk of spilling the size liquid when replenishing the size liquid. And automatic replenishment becomes possible.
