Description

[Detailed Description of the Invention] This invention relates to a conveyor device for feeding a raw fabric in a spreading machine.

Conventionally, in a fabric spreading machine, the fabric from a roll roll that has been sequentially rewound and unrolled by a roll roll unwinding device is sent downward by a feed conveyor device of a belt conveyor disposed at the upper front end of a traveling frame. The original fabric is fed out and spread one after another onto the spreading table via a cutter device or a feeding roll located below, but this conventional fabric feeding conveyor device is installed at a high position above the front end of the traveling frame. Therefore, the fabric path between the feed conveyor device and the downward cutter device or the feed roll is long, and the fabric that is fed downward through this path is likely to stretch due to its own weight. In the case of cloth, there is a drawback in that considerable elongation occurs, which adversely affects the stretching and cutting of the cloth after stretching.

In view of the above, this invention provides a feed conveyor device as described below to eliminate the above-mentioned conventional drawbacks.

The original fabric feeding conveyor device of this invention will be described with reference to the drawings. 1 is a traveling frame of a spreading machine that reciprocates back and forth on a spreading table 3, and 2 is a wheel.

Reference numerals 4 and 5 denote rotating shafts installed and supported in the left-right direction above and below the front end of the traveling frame 1, respectively.The upper rotating shaft 4 has a chain wheel 6,
Chain wheels 8 are also fixed to the lower rotating shaft 5, and the chain wheels 7
, 8 are intertwined with a control chain 9, and a control chain 33 is connected between a chain wheel 32 and a chain wheel 6 of a motor 31, respectively.

Then, an elevating frame that can be moved up and down along the vertical elevating guide 10 and has protruding support portions 11a on both left and right sides is connected to the control chain 9, and the forward and reverse rotation of the motor 31 causes the elevating frame 11 to move up and down. It looks like this.

Reference numeral 12 denotes a cutter device detachably mounted on the front side of the elevating frame 11 directly below the projecting support plate portion 11a.

In the case of unidirectional spreading, the cutter device 12 is attached, but in the case of reciprocating spreading, the feed roll is detachably attached.

Reference numeral 13 denotes a tail shaft installed horizontally on the left and right support plate portions 11a, to which a tail pulley 14 is rotatably mounted.

17 has left and right arm rods 15 fixedly attached to both left and right ends of which the chain wheel 19 is integrated, and furthermore, a connecting rod 20 is rotatably fitted into the left end. It is equipped.

The head shaft 17 is supported by bearings at both ends of the left and right horizontal long holes 16 on the upper left and right sides of the traveling frame 1, so that the head shaft 17 can be easily moved horizontally along both the horizontal long holes 16. It can be slid back and forth.

The other ends of the left and right arm rods 15 are loosely connected to both ends of the tail shaft 13, respectively.

A conveyor belt 34 is wound between the head pulley 18 and the tail pulley 14, forming an inclined feeding conveyor whose inclination changes as the elevating frame 11 goes up and down.

Reference numeral 21 denotes a free shaft which is rotatably supported and inserted into the other end of the connecting rod 20, supported by a bearing 25, and has a chain wheel 23 at both ends.
24 are fixed respectively.

Furthermore, a connecting rod 22 is installed at the left end of the free shaft 21, with one end loosely fitted.

A control chain 26 is entangled between the chain wheels 19 and 24.

Reference numeral 27 denotes a rotating shaft rotatably installed on the traveling frame 1, which is rotatably driven by a motor drive source (not shown) via the one-way mission device 30.

The other end of the connecting rod 22 is loosely connected to the rotating shaft 27.

In addition, the chain wheel 28 is fixed and the pulley 29 is disposed between the chain wheel 23 and the chain wheel 23.
are entangled.

The connecting rods 20 and 22 constitute an inverted dog-shaped link mechanism as shown in Figures 1 and 2, and the head shaft 1
1 moves back and forth along the horizontal elongated hole 16, the angle of refraction of the above-mentioned inverted dogleg shape changes, but the head pulley 18 is always rotated via the control chain 29°26 by the drive from the motor drive source. It can be driven.

This devised device has the above-mentioned configuration, and when the motor drive source (not shown) is operated, the rotating shaft 27 rotates via the one-way mission device 30, and the head is rotated via the chain wheel 29. The pulley 18 rotates in the direction of the arrow and the conveyor belt 3
Reference numeral 4 rotates in the direction of the arrow in Fig. 1, and the cloth 35 unrolled from the unrolled side and fed out is sequentially fed out by the above-mentioned feed conveyor that rotates in the direction of the arrow as shown in Fig. 1, and is delivered to the cutter. The sheets are sequentially fed out and spread onto the spreading table 3 via the device 12 or the feeding rolls.

Since the cutter device 12 rises slightly each time the traveling frame 1 makes one reciprocation, each time the cutter device 12 rises, the head shaft 17
is moved backward little by little in the horizontal elongated hole 16, and the inclination of the feed conveyor device changes to become gentler little by little.

As mentioned above, the original fabric feeding conveyor device of this invention has the following features:
A head shaft 17 on which a head pulley 18 is rotatably mounted is supported in a horizontal elongated hole 16 at the top of the running frame 1, and a tail shaft 13 on which a tail pulley 14 is rotatably mounted is supported on the running frame. 1. The head pulley 1 is installed horizontally on the left and right raised plate parts 11a of the cutter device or the elevating frame 11 for the feeding roll at the lower front end.
8 and the tail pulley 14 to form an inclined conveyor belt 34, the fabric 35 sequentially sent out by the feed conveyor device is immediately transferred to the cutter device 12 or the delivery roll from the transmission end of the conveyor. The drooping length of the fabric 35 between the end of the conveyor transmission and the cutter device 12 or the feed roll is extremely small and has the excellent effect of completely preventing the fabric from stretching under its own weight. , which will not have any adverse effect on the spreading or cutting of the fabric after spreading.

In addition, the slow shaft 13 is installed on the English version part 11a of the lifting frame 11, and it is used as an inclined feeding conveyor whose inclination changes as the lifting frame 11 goes up and down. There is an effect that the cloth material 35 can be smoothly and reliably fed out without causing any elongation in the cloth material 35 at all times.
