Description

[Detailed description of the invention] <Technical field> The present invention automatically removes and collects the empty fabric shaft after spreading from the support arm of the main body of the spreading machine that travels back and forth on the spreading table. On the other hand, the present invention relates to an automatic fabric shaft supply/recovery device for a fabric spreading machine which is capable of automatically supplying and mounting a fabric spindle for a new roll onto a supporting arm of the main body of the fabric spreading machine.

<Prior Art> Conventional fabric spreading machines have an automatic fabric shaft feeder, but do not have a function or mechanism for automatically collecting the empty fabric spindle after fabric feeding or spreading. The prior art will be explained based on the simplified side view of FIG.

The spreading machine main body 2' reciprocates on the spreading table 1',
A cloth shaft automatic feeder 4' for automatically feeding the roll 3 is provided opposite to the cloth-spreading machine main body 2', which has a cloth-spreading roll 8' pivotally attached to the front end thereof.

The automatic fabric supply device 4' has a pair of upper and lower (left and right) support claws 10a, 10b fixedly protruding from the left and right endless link chains 9' at predetermined intervals, respectively, to circulate up and down, and to feed the endless link chain 9'. The protruding base of the roll shaft is supported by the claws 10a and 1 at the front end of the roll stock part 4'', which is an arm rod projecting outward from the link chain 9'.
The protruding end of the fabric shaft is supported by the bent portion of the fabric shaft 0b, moves upward, forward, downward, and waits while tilting upward in the middle of the front end. Due to the weight of the cloth shaft 3', the cloth shaft 3' is hung in the support arm 5' beyond the opening/closing mechanism of the cloth shaft support recess 6' formed between the protruding rod and the upper rod, and the support arm 5' is rotated forward. The roll 3 is spread by the rotation of the spreading roll 8' and the running of the spreading machine main body 2'.

As described above, the function of the conventional cloth shaft automatic feeding device is that when the reciprocating movement and the spreading work by the cloth spreading roll 8' are completed and the cloth 3 wound around the cloth shaft 3' is exhausted, the cloth shaft 3' is clamped. By rotating the supporting arm 5' from the front end position indicated by the dashed line to the rear end position indicated by the solid line in the figure, both protruding ends of the cloth shaft 3', which is held in the support recess 6' so as not to fall off, can be opened and closed. After the latching mechanism 7 is forcibly disengaged and moved downward and received manually, the now empty support arm 5' is rotated from the solid line position in FIG. 1 to the supply position indicated by the upper double-dashed line. ,
The next fabric shaft 3' of the fabric roll 3 is fed again by a pair of upper and lower support claws 10'a and 10'b pivoted to the endless link chain 9' which circulates in the direction of the arrow of the automatic fabric shaft feeder 4'. is received by the support arm 5'.

Therefore, although it was possible to automatically attach the fabric shaft 3' to the fabric spreading machine main body 2', manual work was required to remove the blank fabric spindle 3' from the fabric spreading machine main body 2. There was an inconvenience that the entire process of attaching and detaching the cloth shaft 3' was not automated.

<Purpose> The present invention is capable of removing the empty cloth shaft after the completion of spreading and attaching the cloth shaft of the next roll by using a pair of supporting claws and a holding frame for collection. An object of the present invention is to provide an automatic feed and recovery device for a roll shaft in a spread machine that can be automated.

<Example> Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

Rolls 3a, 3b, 3 for the spreading machine main body 2
As shown in FIGS. 2 and 4, the automatic feed/recovery device 4 for cloth shafts such as c and 3d is installed behind the sheet spreading table 1, and is installed so as to circulate the endless link chain 9 up and down, respectively. a pair of left and right vertical base frames 24;
The most important aspect of the present invention is a holding frame 26 for collecting empty shafts protruding from the front lower part of the vertical base frame, and a roll stock part 29 protruding from the rear end of the vertical base frame 29 facing away from the holding frame 26. The left and right endless link chain 9 is provided with a pair of upper and lower support claws 10a and 10b at predetermined intervals in a pivotally protruding manner. The motor 3 is on the stand 23.
It is set to 0.

The left and right vertical base frames 24 have substantially round-shaped sides, with upper rods protruding upward from the spreader main body 2, and bent portions of the outer edges of the upper arm rods and sprockets 2 on the outer surfaces of the lower ends.
7, 27, 27, 27, 27, the rotational driving force of the motor 30 is transmitted to the lower end sprocket 27 via the pulley, and the endless link chain 9 is moved in the direction of arrow C in FIG. top, front,
It is circulated downward and backward.

The pair of support claws 10a, 10b are provided in three pairs on the left and right in the figure, and the left and right sides synchronously circulate relative to each other, and each of the supporting claws 10a, 10b, respectively, supports each of the protruding ends of one of the cloth shafts 3'A, 3'B... As shown in the enlarged perspective view of FIG. 4, the pair of upper and lower mounting positions are the upper portions of the left and right endless link chains 9 that circulate up and down along the rear end surface of each vertical base frame 24. The link and the lower link are rotatably mounted on the outer and inner end surfaces with pins with different vertical phases, and the left and right protruding bases of the fabric shaft 3'A are horizontally attached to the upward bifurcated portions of the support claw 10a. It circulates through the endless link chain 9 and is supported by the two crotches of either of the supporting claws 10a or 10b that face each other in any direction of upward, horizontal, oblique, or downward movement. never deviate. 28 is a clearance groove for the support claw 10b.

The collection holding frame 26 has a substantially U-shaped side surface and a planar surface, and the front upper end of the upper rod 25 is located at the rear, slightly lower than the rear end of the spreader main body 2, and when the material shaft support arm 5 rotates backward. The cloth shaft 3', which has descended from above the rear end, is prevented from rolling and escaping by the front vertical rod of the holding frame 26.

A spare roll 3 is stored in the roll stock part 29.
b, 3c... are mounted on shafts, and slide to the front end in order to wait.The left and right protruding rods of the stock portion 29 are provided at the outermost side of the rear end of the vertical base frame, and relief grooves 28 are bored inside thereof. A support claw 10b is pivotally attached to the outer end surface of the link chain with a pin so as to fit into the relief groove 28.

The spreader main body 2, which is installed opposite to the above-mentioned automatic feed and recovery device 4, has a pair of left and right support arms 5 pivoted on both sides of its upper end mounting base 2A so as to be able to rotate approximately 180 degrees in the front and rear directions. The protruding free end of the support arm constitutes a support recess 6 for supporting the cloth shaft, and the protruding lower rod 1
A stopper 15 that opens and closes the opening of the support recess and locks the cloth shaft 3' is pivotally mounted eccentrically at the rear 18, and is normally biased forward and upward by the free end of a leaf spring 22 to support the cloth shaft 3'. When the support arm 5 is latched in the recess 6 and rotated backward, the rear lower end surface 20 of the stopper 15 collides with the protruding abutting plate 21' of the guide plate 21 that is inclined and protrudes from the rear end of the spreader main body 2. The stopper 15 is held horizontally by the stop plate 17 against the biasing force of the leaf spring 22, and the cloth shaft 3' is caused to roll from the support recess 6 onto the guide plate 21 outside the rear end. .

In the figure, 13 is an upper rod, 16 is a through hole, 17' is a set screw, and 19 is a bent front rod of the stopper 15.

The sheet spreading machine main body 2 and cloth shaft automatic supply/recovery device 4 having the above configuration are equipped with an automatic control section (not shown) in which necessary data such as sheet spreading distance and number of sheets are stored for automatic control. If you do this, the empty cloth axis 3'
The collection of the next roll, the attachment of the roll shaft 3' of the next roll to the support arm 5, the spreading and traveling of the main body of the roll spreading machine, etc. can all be carried out automatically.

<Function> The function of the automatic material shaft supply/recovery device in the spreading machine of the present invention having the above configuration is as follows.

When starting the spreading work by running the spreading machine main body 2, rotating the spreading roller 8, and rotating the endless link chain 9 by the motor driven by the automatic control device, the support arm 5 moves as shown in FIG. At the standby position indicated by the dashed line at the rear end, the roll shaft 3' of the descending roll 3A is supported, and when the roll 3A is clamped into the support recess 6 by its own weight, it rotates forward and starts spreading. , the opened support claws 10a, 10b move downward and approach the upper end of the holding frame, while the next support claws 10a, 10b on the endless link chain 9 move the rolled material 3A, which is movably supported from the material stock section 29, upward. The vertical base frame 2 is moved while supporting the cloth shaft 3'.
The third support claw 10a,
10b receives the next cloth shaft 3' from the stock portion 29, and is adjusted so that it is in a slightly upwardly rotated position.

As the fabric spreading operation progresses, the support arm 5, which holds the fabric shaft 3' which is empty after feeding out the fabric, rotates to the rear end, and as shown in FIG. 2, the rear lower end surface 20 of the stopper 15 is Colliding with the abutting plate 21' of the guide plate 21, the bent front rod 19 rotates downward about the shaft 18 against the biasing force of the leaf spring 22, and the stopper 15 is flush with the protruding lower rod. The cloth shaft 3', which had been clamped and locked in the support recess 6, immediately rolls down on the protruding lower rod 12 in the direction of arrow D in FIG. The support claw 10b moves backward and is supported by falling into the upward support portion of the waiting support claw 10b.
Due to its weight, the support claw 10b supporting the empty cloth shaft 3' is rotated slightly forward using the pin near the lower end as a fulcrum, and descends in a state protruding forward from the support part of the support claw 10a, and moves downward toward the bottom of the holding frame. When reaching the folding curve of the endless link chain 9, it rolls out from the forward-inclined support part of the support claw 10b into the holding frame. Empty support claw 10
A and 10b go up on the opposite side along the curve and reach the stock section to receive the rolled fabric.

On the other hand, the support arm 5 whose support recess 6 has become empty due to rolling of the cloth shaft 3' rotates upward as shown by arrow E (double-dotted line in FIG. 2), and in synchronization with the upper rod 25. Support claw 10' holding the roll 3A waiting above
a and 10'b are lowered to the delivery position indicated by the two-dot chain line in FIG. , the spreading work will be resumed.

Note that the support claws 10a that have ascended to the stock portion,
To explain the action of the link chain 10b in more detail, as the endless link chain 9 moves upward, the most protruding bases of the two-pronged cross-shafts extending horizontally on the stock part 29 first hit the supporting claws 10b that have moved upward. Because it faces downward, there is no support part, and it protrudes and is a hindrance. However, since the relief groove 28 is bored, the support claw 10b swings and enters into the relief groove 28 using the upper end pin as a fulcrum. A slightly lower support claw 10a moves upward and supports the protruding base of the cloth shaft.

<Effects> The above-described automatic feed and recovery device for the paper shaft in the spreader of the present invention has the following effects.

(1) A holding frame with a simple structure for collection is provided between the vertical base frame 24 and the main body of the spreading machine, and is made to correspond to the supporting claws of the endless link chain. The cloth shaft is attached to the supporting claws 10a, 1
It can be easily and safely removed by supporting the transition to 0b, and
Since the holding frame is carried to the bottom by the support claws, the fabric shaft will not be damaged or make noise if dropped from a high place.

(2) Empty cloth shafts taken out can be automatically moved and assembled into the holding frame for collection only by circulation of the endless link chain.

(3) The removal of the empty cloth shaft after the completion of the rolling and the attachment of the cloth shaft for the next roll of cloth can be carried out completely automatically without the need for human intervention.
