Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flocking device in which a pile yarn is inserted into a base cloth by a needle, and the inserted pile yarn is received by a looper to form a pile.

[0002]

2. Description of the Related Art In this type of flocking apparatus, a tufted machine in which hundreds of needles are simultaneously inserted into a base cloth to plant a large number of piles and a pile with one needle are planted one by one. There is a hook machine to do. Tufted machine,
Although suitable for high-speed mass production of pile fabrics, it is not possible to draw complicated and varied designs on the pile surface, and thus the designs that can be drawn on the pile surface are limited to simple ones with short two-color repeats. On the other hand, if a hook machine is used, pile piles can be planted by switching pile yarns according to the color of the original picture, so it is possible to draw complex and various patterns, but since the operation is manual, it The production efficiency of the pile fabric produced by the method is lower than that of the tufted machine.

[0003]

SUMMARY OF THE INVENTION Therefore, Japanese Patent Application Laid-Open
As described in Japanese Patent Publication No. 33860 (Japanese Patent Publication No. 1-35855), a second carrier mounted on a first carrier running on a pair of first rails facing in parallel and bridged between the first rails facing in parallel. A hook machine is mounted on a second carrier running on a rail, a base fabric is stretched between a pair of first rails facing in parallel, and the first carrier and the second carrier are driven to connect the hook machine to the base fabric. A method has been developed to move piles and piles to automatically pile. However, in the device that automatically operates the hook machine, the reaction force received by the hook machine from the base fabric at the time of pile planting differs between the central portion and the peripheral portion of the base fabric stretched in the base fabric stretching. It is difficult to evenly pile the entire surface of the cloth.

Accordingly, Japanese Patent Laid-Open No. Hei 6-2257 (Japanese Patent Publication No.
86700), a large number of base cloth support members are arranged vertically and horizontally on the entire inner surface of the base cloth upholstery frame, and the plurality of base cloth support members are individually moved by following a moving hook machine. It must be selected and driven up and down, and the base cloth support material that is pushed up must support the base cloth so as to protrude toward the hook machine.By arranging a large number of base cloth support members vertically and horizontally, the entire flocking device becomes larger. , The maintenance management becomes difficult.

・ Hooked on 50 stop needles and tensioned back and forth. A guide roll 51 is provided between the ends of the first rails on the left and right.
However, guide rolls 52 are respectively bridged between the rear ends of the left and right first rails. When the base fabric 29 received on the first carrier 16 via the second carrier 18 and the base fabric tension frame 19 moves back and forth together with the first carrier 16, their guide rolls 51 and 52 rotate,
Between the base fabric tension frame 19 and the guide rolls 51 and 52, the base fabric 2
9 is not to be slackened or nervous. Outside the guide rolls 51 and 52, a delivery roll 5 is provided.
3 and the take-out roll 54 are respectively set in parallel,
The base fabric sent out by the guide rolls 51 and 52 is
It hangs down between the guide rolls 51 and 52 and the delivery roll 53 and the take-out roll 54 and is temporarily stocked.

Three or more base cloth stoppers 50 are prepared, and extra base cloth stoppers 50 attached before and after the base upholstery frame are removed from the base upholstery frame by planting a pile. When moving the backed cloth and reattaching it to the base upholstery frame and starting flocking again, place the extra base cloth stopper on the next base cloth to be stopped on the horizontal frame of the base upholstery frame. Should be attached in advance. In this case, the chain belt 48 is turned, the base cloth 29 is conveyed on the base cloth upholstery frame 19, and the base cloth stopper 50 attached to the base cloth is fixed to the horizontal frame member 49. ,
As in the case where a fabric is intermittently set on a flat screen board and a pattern is continuously printed in a flat screen printing machine, a pattern can be drawn by continuously planting a pile on the base cloth 29. .

FIGS. 3 and 4 show a flocking device for automatically and intermittently transporting the long base cloth 29 and continuously laying piles as shown in FIG. In the flocking device, the base cloth 29 is detached from the base cloth upholstery frame 19, transported, and the manual work of re-stretching the base cloth 29 is repeated.
The pile will be planted continuously.

The needle bar 42 includes US Pat.
