DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for adjusting a trick plate interval in a double Raschel machine.

[0002]

2. Description of the Related Art Conventionally, when adjusting the interval between two opposing trick plates in a double Raschel machine,
It is necessary to adjust the length of the adjustment rod which is indirectly connected to the trick plate.
In the case of the inch model, it is necessary to loosen the adjustment rods at a total of about 12 places in each of the 6 places before and after, adjust their lengths, make fine adjustments to the trick plate interval using a dial gauge, and then tighten each adjustment rod was there.

[0003]

In the conventional method of adjusting the interval between the trick plates, the adjustment work must be performed for each adjustment rod, so that it takes a long time, and the burden on the operator is large. Fine-tuning was difficult for non-experts. SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for adjusting the gap between trick plates in a double Raschel machine easily and in a short time even if the user is not an expert.

[0004]

In a double Raschel machine having a pair of trick plates, each trick plate is connected to a displacement generating means for generating a displacement by an eccentric mechanism via a displacement transmitting means. , A lock means is attached to the eccentric mechanism.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A displacement generating means is connected to an arm lever which is a displacement transmitting means, and is attached to a support shaft provided at one end of the connecting rod and supported on a machine frame. With the eccentric member formed as described above and a lever fitted to the support shaft, each of the pair of trick plates can be individually moved.

[0006] A displacement generating means is connected to an arm lever as a displacement transmitting means, and an eccentric mounted on one end of the connecting rod and fitted on a support shaft supported on the machine frame. Consists of a member, a lever fitted to the support shaft, an arm fitted to the support shaft, and a joining pin slidably connected in the elongated through-hole so that the arms cross each other. As a result, each of the pair of trick plates can be simultaneously moved.

A locking member is fixed to the machine frame, a lever is fitted on a spindle supported by the machine frame, a handle is fixed to the tip of the lever, It consists of a lock handle that is inserted through the elongated hole and screwed to the support member, and the gap between the trick plates can be fixed after the displacement adjustment, so that the gap between the trick plates is constant after the displacement adjustment Is kept.

[0008] A trick plate spacing adjustment is achieved by providing a needle on an attachment member fixed to the machine frame so that the angle scale displayed on the side surface of the eccentric member fitted on the support shaft can be indicated. The measurement of the displacement at the time is performed accurately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 are a partial sectional side view and a partial sectional front view, respectively, of a first embodiment of a trick plate spacing adjusting device in a double Raschel machine according to the present invention, and FIG. 3 is an embodiment of a second embodiment of the present invention. It is a partial section side view. 1 and 2, a trick plate adjusting device 16 includes a pair of support shafts 9a and 9b supported on the machine frame 1, and levers 2a and 2b fitted on the support shafts 9a and 9b, respectively. Handles 7a, 7b fixed to the respective ends of the levers 2a, 2b;
A pair of support members 3a, 3b fixed to
A lock handle 8 which is inserted into the through-holes 2c, 2d of each of the support members 3a, 3b and screwed into each of the support members 3a, 3b.
a, 8b, eccentric members 4a, 4b fitted to the support shafts 9a, 9b, and connecting rods 5a, 5b rotatably connected at one end to the eccentric members 4a, 4b, respectively. And rotatably connected to the other ends of the connecting rods 5a and 5b, respectively.
Arm levers 14a, 14b holding each of 1a, 11b and rotatably supported on a pair of arm lever support shafts 18a, 18b supported on the machine frame 1,
The eccentric members 4a, 4
b. Attachment members 6a and 6b provided with needles 13a and 13b so as to support the angle scale displayed on each side surface of b.

When the lock handle 8a is loosened, the handle 7a
When the lever 2a is pushed down in the direction of arrow A, the eccentric member 4a rotates in the direction of arrow A together with the support shaft 9a, and the connecting rod 5a descends in the direction of arrow C.
4a rotates about the arm lever support shaft 18a as a fulcrum, and the trick plate 11a moves in the direction of arrow D.
At this time, the angle scale on the eccentric member 4a is checked with the needle 13a, and then the lock handle 8a is tightened, so that the position of the trick plate 11a is appropriately fixed,
Similarly, when the lock handle 8b is loosened and the lever 2b is pushed down to move the trick plate 11b in the direction of arrow E, the angle scale on the eccentric member 4a is checked with the needle 13a, and then the lock handle 8b is tightened.
Since the position of the trick plate 11b is appropriately fixed, as a result, the interval between the pair of trick plates 11a and 11b is increased. When the distance is reduced, each of the levers 2a and 2b is pulled up in the opposite direction to the case where the distance is widened, and the adjustment is performed.

In FIG. 3, a trick plate adjusting device 17 includes support shafts 9a and 9b, levers 2a and 2b, handles 7a and 7b, support members 3a and 3b, and a lock handle 8.
A, 8, eccentric members 4a, 4b, connecting rods 5a, 5
b, arm levers 14a, 14b, and attachment members 6a, 6b provided with needles 13a, 13b have the same configuration as the trick plate interval adjusting device 16 in FIG. 1, and further, each of the support shafts 9a, 9b has Elongated holes 12a, 12b
Arms 12a and 12b, which are connected in a crossing and slidable manner by joining pins 15, are fitted therein.

Lock handles 8a, 8b and joining pin 1
When the lever 5 is loosened and the lever 2a is pushed down in the direction of arrow A with the handle 7a, the eccentric member 4a moves together with the support shaft 9a in the direction of arrow B.
And the connecting rod 5a descends in the direction of arrow C, so that the arm lever 14a is moved to the arm lever support shaft 18a.
And the trick plate 11a moves in the direction of arrow D, and at the same time, the arm 12a rotates in the direction of arrow C together with the support shaft 9a, so that the support shaft 9b rotates and the connecting rod 5b moves in the direction of arrow H. Descend in the direction. The lowering of the connecting rod 5b causes the arm 14b to rotate about the arm lever support shaft 18b as a fulcrum, and the trick plate 1
1b moves in the direction of arrow I. At this time, the eccentric member 4
After confirming the angle scale on each of the hands 13a, 13b with the lock handles 8a, 8b and the joining pins 15a, 13b.
By tightening, the trick plates 11a, 1
Since the position of 1b is simultaneously and appropriately fixed, the distance between the trick plates 11a and 11b is widened as a result.
When the interval is reduced, the adjustment is performed by pulling up the lever 2a or the lever 2b in a direction opposite to the direction in which the interval is increased.

[0013]

According to the present invention, it is not necessary to adjust the adjusting rod for each rod, and the amount of movement of the trick plate can be accurately measured without using a dial gauge. In addition, the interval between the trick plates can be adjusted in a short time.
