Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a long cloth feeding device, etc., which hangs a long cloth in a loop shape from a number of support bars and sequentially feeds the cloth by moving the support bars. This invention relates to a feeding device for measuring objects.

[Conventional technology]

The fabric feeding device installed in the evaporator that vaporizes cloth has a pair of parallel chains stretched through an upper transition path and a lower transition path in the evaporation chamber, and support bars are placed at equal intervals between the chains 7. The cloth is suspended in a loop shape from a support bar that passes through an upper transition path, and the cloth is fed sequentially by the movement of the support bar.

[Problem that the invention seeks to solve]

In the above-mentioned cloth feeding device, the arrangement pinch of the support bars is determined based on the interval required to hang the cloth in a loop from the support bar at the upstream end of the upper transition path, and this pitch is approximately 2.00 mm.
It is. However, after the cloth is wrapped around the support shafts, this 20cm interval between each support shaft is too wide and becomes a wasted space.
There was a problem in that the evaporation equipment became large and required a large installation space, which increased the amount of steam used and increased running costs.

[Means to solve the problem]

Connecting pin (32) that constitutes the transport chain t3) (3)
Among (32a), one or more connecting pins (32
), a wheel (42) is attached to the support bar (4) or an extension of the support bar, and a rail (51) for supporting the wheel is provided on the upper transition path.

A feed chain sprocket (26) that engages with the conveyor chain (3) is provided on the upstream side of the upper transition path, and a single control chain sprocket (6) that rotates at a lower speed than the feed chain sprocket is provided on the downstream side of the transition path. Deploy.

[Action and effect]

The chain 7 is bent between the feed chain sprocket (26) and the control chain sprocket (6), which rotates at a lower speed than the sprocket, and the gap between the support bars +41 becomes narrower, and in this state it moves downstream. .

■After passing the control chain sprocket (6) on the upstream side, the conveyor chain (3) extends again.

The gap between the support bars between the feed chain sprocket (6) where the conveyor chain (3) moves in a bent state and the control chain sprocket (6) becomes clogged, causing the length of the batch evaporator to be shortened due to the tight gap. In this way, the amount of steam used can be reduced.

A cloth intake port (13) is provided at one end of the horizontally long casing (12) constituting the vaporization chamber (11) of the vaporization device (1), and a fabric drawer port (14) is provided at the bottom of the other end. be done.

Chain sprockets (21) (22) +23) (24) are arranged at the four upper and lower corners of the vaporization chamber (11), and a pair of endless conveyor chains (3) are installed on the sprockets.
1 (31) are stretched parallel to the longitudinal direction of the housing.

The conveyor chain (3) is attached to the upper chain sprocket L-(21).

For convenience, connect each chain sprocket above to the cloth intake port (13
) side upper chain sprocket (21) in the circumferential direction of chain 7.

Approaching the first sprocket (21), the sprocket (
An auxiliary chain sprocket (25) is disposed downstream of the auxiliary chain sprocket (21) at a position higher than the first sprocket, and a feed chain is disposed downstream of the auxiliary chain sprocket (21) at a position slightly lower than the auxiliary chain sprocket (25). Sprocket □

The conveyance chain (3) passes through the upper part of the auxiliary chain sprocket (25+) and the lower part of the feed chain sprocket f2G+.

3rd chain sprocket) (Intermittent rotating device (obscene) is connected to 23+.

Between the transport chains t31+3+, a large number of support bars (4) for hanging cloth are arranged perpendicular to the circumferential direction of the chains 7(3).

The pitch of the connecting pins (32) (32a) that pivotally connect each link plate (31) +31) of the conveyance chain (3) is approximately 1.
00mm, and there are rollers (3) on the outer periphery of each connecting pin (32) (32a) between the link plates (3], ) (31).
3) is fitted so that it can rotate freely.

Of all the connecting pins (32) (32a) of Che 7, 1
Tsuhihi's connecting pin (32) has link plates (31) on both ends.
(31), and the protruding inner end of the connecting pin (the protrusion) fits into the end of the support bar (4) so as to rotate freely regardless of the rotation of the support bar (4), and the connecting pin (32) An auxiliary roller (41) is rotatably fitted to the protruding outer end.

Wheels (42) with a diameter of approximately LOOrtvn are attached to both ends of the support bar (4) so as to rotate freely regardless of the rotation of the bar (4), and a rotation control chain sprocket with a slightly smaller diameter than the wheels (42) is attached to both ends of the support bar (4). (431 is the support bar (
4) is fitted and fixed.

The first sprocket (2j) and the second sprocket (2j)
2) A guide i5) that guides the auxiliary roller (41) corresponding to the upper transition path of the conveyance check 7 (3) in between.
5) and also rails (51) which removably support the wheels (42) are provided.

The chain 7' is located above the downstream side of the upper transition path of the conveying chain (3) and downstream of the feed chain sprocket (26).
Close to oket f26) and control chain sprocket +
6) +61) is deployed.

Both control chain sprockets (61+61) are formed in the same shape as the feed chain sprocket (213), and are connected to the intermittent rotating device (M+) via a deceleration transmission means (not shown), and are connected to the - of the feed chain sprocket (26). It rotates in the same direction as the chain sprocket (26) at a speed of .

In the example, two control chain sprockets (6) (6
1) is the feed chain sprocket (located at a position approximately 2σ lower than the sword).

A rotation control chain sprocket +43+ fixed to the support bar (41) corresponds to the upper transition path of the conveyor chain (3).
A rotation control chain (7) engaged with is rotatably provided, and the chain (7) is connected to the intermittent rotation device (71) via a transmission (71).

However, while the transport chain (3) was stopped running, the support bar +4 between the guide roller (8) on the cloth intake port (13) side and the first sprocket (f21) and the auxiliary sprocket (25) -) +4) Drape the cloth (9) in a loop between the two.

The above operation is performed every time the conveyance chain (3) advances one pitch and stops, and the cloth is hung in a loop between each support bar +41 (41).

When the link plate (31) of the conveyor chain (3) (311 passes through the feed chain sprocket α), the rotational speed of the control sprocket L-(61) on the downstream side of the sprocket (2G) is reduced by half compared to the feed chain sprocket. Therefore, a force in the direction of contracting the conveyor chain (3) acts between the feed chain sprocket (26) and the control sprocket (61).

Of the connecting pins (32) (32a) of the conveyance check 7 (3), one connecting pin (32) is connected to the guide (5) and the rail (
Auxiliary rollers (41) and wheels (4) guided by
2) is connected, the remaining connecting pin (32a)
The link plates (31) (311) bend alternately, and the adjacent wheels (421 (421) come into contact with each other.

Link plate + 31) When (31) bends, the weight of the link plate (311 (31) acts and does not bend upward, and as in the example, the control chain sprocket (A) is not bent upward). (By keeping the height position of 611 low, the downward bending operation of the link plate (3I) becomes even smoother.

Since the diameter of each wheel (42) is 100 mm, the distance between the axes of adjacent support bars +4] (4) is 1-00 i
It shrinks to n.

As mentioned above, the support bar is support bar + 4) (4+ spacing,
In other words, the distance between the loops of the cloth hanging on the support bar in a loop is shifted to the downstream side, but the control chain sprocket (43) fixed to the support bar (4) is connected to the control chain (7).
Since the chain (7) is engaged with the conveyor chain (3),
) Corresponding to the speed difference between the control chain sprocket wheels (431), the support bar (4) therefore shifts from rotating on its own axis.Therefore, the fabric is not only fed by the lateral movement of the support bar (4), but is also fed by the support bar (4). Due to the rotation, the cloth is fed in a loop around the bar (4), and the contact surface of the cloth with the support bar (4) changes, thereby preventing uneven evaporation of the cloth.The control chain (7) controls each support bar (t4). [4] It is possible to completely match the rotational speed of the cloth and each support bar (
The contact conditions with 4) are the same, and each support bar [4,)
[4), +4) The loop length of the cloth between +4) can be kept constant, and the cloth will not drip onto the bottom of the evaporation chamber (]1).

In addition, the speed of the control chain (3) is controlled by the support bar (4) that supports the cloth (9).
) can be determined by the transmission device (71) so that the support bar (4) rotates at an optimum speed depending on the delicate degree of slippage between the cloth and the bar (4) when the cloth is stretched in a loop shape. In the embodiment, the speed of the control chain (7) is the same as that of the conveyor chain (7).
3) is -.

When the conveyance chain 7 (3) passes the control chain sprocket (6) on the downstream side of the upper conveyance path, it is pulled by the third chain sprocket (23) and the ring plate (31+ +311) of the conveyance chain (3) The cloth extends straightly.At the original end under the upper conveyance path, the cloth passes through the downstream guide roller (8) and is pulled out from the cloth draw-out opening (insertion).

As mentioned above, in most of the feeding sections, the conveyance check 7 (3
) are bent, the distance between the support bars +41 and +4+ is narrowed, and the fabric is fed sequentially, making it possible to significantly shorten the length of the machine and greatly reduce the amount of steam used.

Incidentally, when carrying out the present invention, even if the upstream chain sprocket (61+) of the two control chain sprockets (13) and (61) is omitted, the conveyor chain 7 (3) can be bent and shortened. In this case, the feed chain sprocket (2
6) and the downstream control chain sprocket (6), the transition path is sloped so that the downstream side goes down (by doing so,
Support bar [4] Between t4+ is clogged in order from the downstream side, and support bar +41 (4), and between (41ta), wheel (4
It is determined correctly according to the diameter of 2).

Furthermore, even if the control chain (7) is fixed without rotating, the rotation speed of the support bar +4) (4j) passing over the chain 7 (7) can be decreased.

Alternatively, if you only want to match the rotational speeds of the support bars (4), a rack rod may be fixedly provided in place of the control chain (7), and a gear that meshes with the rack rod may be fixed to the support bar. Yes.

Furthermore, the wheel (42) is fixed to the support bar (4), and the wheel (42) is simply placed on the rail (51).
) can also be transferred while rotating together.
