Description

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

<Prior Art> Conventional fabric spreading machines have an automatic fabric shaft feeder, but do not have a function or mechanism for feeding the fabric or automatically collecting empty or unrolled fabric stems after 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',
An automatic fabric feeder 4' for automatically feeding the fabric 3 is provided opposite to the fabric spreading machine main body 2', which has a fabric spreading roll 8' pivotally attached to its front end.

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'. Link chain 9' A roll stock portion 4'' consisting of an arm rod projecting outward.
The claws 10a, 10b support the protruding base of the cloth shaft at the front end of the
The protruding end of the fabric shaft is moved and supported by the protruding lower rod of the supporting arm 5' which moves upward, forward, downward and stands by while tilting upward in the middle of the front end, and supports the protruding end of the fabric shaft 3.
Due to the weight of the cloth shaft 3', the cloth shaft 3' passes through the opening/closing mechanism of the cloth shaft support recess 6' formed between the protruding rod and the upper rod and is hung in the support arm 5', and the support arm rotates forward. The roll material 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 such that after the reciprocating movement and the spreading work by the cloth spreading roll 8' are completed, the roll 3 wound around the cloth shaft 3' is no longer available, or only half of the roll is left unrolled. Then, the support arm 5' holding the cloth shaft 3' is rotated in the opposite direction from the front end position indicated by the dashed dot line to the rear end position shown in solid line in the figure, and the cloth shaft 3 is held in the support recess 6' without falling out. Both protruding ends of ' are forcibly disengaged from the opening/closing latching mechanism 7 and moved downward, and after being received manually, the empty support arm 5' is moved upward from the solid line position in FIG. A pair of upper and lower support claws 10'a, which are pivoted on an endless link chain 9' which rotates to the supply position shown by and circulates again in the direction of the arrow of the automatic sheet feeder 4'.
The support arm 5' receives the roll shaft 3' of the next roll 3 fed by the support arm 5'.

Therefore, it was possible to automatically attach the rolled fabric shaft to the main body of the spreading machine, but when removing the fabric shaft 3' from the spreading machine main body 2' due to unrolled fabric after spreading or empty winding, etc. However, there was an inconvenience in that the entire process of attaching and detaching the cloth shaft was not automated, which required manual labor.

<Purpose> The purpose of this invention is to remove the fabric shaft after finishing the fabric spreading,
The installation of the cloth shaft for the next roll can be automated by adding a pair of support claws, a guide rod for collection, and an empty shaft collecting section. The purpose is to provide a collection device.

By doing so, it is possible to collect the unrolled fabric shaft 3' or the empty fabric spindle 3', attach the fabric shaft 3' of the next rolled fabric 3 to the support arm 5, spread the fabric, run the fabric, etc. Everything can be done automatically.

<Function> The function of the automatic paper shaft supply/recovery device 4 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 26, while the next support claws 10a, 10b on the endless link chain 9 move and support the rolled material 3b from the material stock section 29. It is moved upward and waits at the upper rod of the vertical base frame 24 while supporting the cloth shaft 3'B, and the third support claw 1
The shafts 0a and 10b are adjusted so that they receive the next roll shaft 3C from the stock section 29 and are at slightly upwardly rotated positions.

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 abutment 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 becomes flush with the protruding lower rod 12. In this state, the cloth shaft 3', which had been clamped and locked in the support recess 6, immediately moved to the protruding lower rod 12.
The upward direction of the support claw 10b that rolls down in the direction of arrow D in FIG. It falls into the bearing part and is supported.
Due to its weight, the support claw 10b that supports the cloth shaft 3' is rotated slightly forward about the pin near the lower end, and descends while protruding forward from the support part of the support claw 10a, and is moved downward toward the bottom of the holding frame 26. When reaching the folding curve of the endless link chain 9, the mounting base frame 4a vertically installed outside the vertical base frame 24 from the forward tilting support part of the support claw 10b

b goes up on the opposite side along the curve, reaches the stock section 29, and receives the roll 3d. Empty shaft recovery section 4
The empty cloth shaft 3' that has rolled on b, 4b is supported by a lower end stopper portion, or if there is no stopper portion, it is supported by an appropriate recovery device or the like.

On the other hand, the support arm 5, whose support recess 6 has become empty due to rolling of the cloth shaft, is placed on standby on the upper rod in synchronization with the upward rotation shown by arrow E (dotted chain line in Fig. 2). Support claws 10'a, 1 that held the rolled material 3A
0'b is lowered to the delivery position indicated by the two-dot chain line in FIG. Spreading work will resume.

Note that the support claw 10 that has ascended to the stock portion 29
To explain the functions of a and 10b in more detail, as the endless link chain 9 moves upward, the protruding bases of the most advanced cloth shaft 3' horizontally suspended on the stock part 29 first hit the supporting claws 10b that have moved upward. Support claw 10
Since b faces downward, there is no support part, and it protrudes and becomes a hindrance. However, since an escape groove 28 is bored, the support claw 10b swings and enters into the escape groove 28 using the upper end pin as a fulcrum. , slightly lower support claw 10a
comes up and supports the protruding base of the cloth shaft 3'.

<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) Guide rods 25, 25 for recovery and an empty shaft recovery part 4b having a simple structure are provided to protrude from the front between the vertical base frame 24 and the spreading machine body and to the rear of the vertical base frame, respectively, and the endless link chain is By matching the supporting claws, the empty or unrolled fabric shafts can be transferred from the supporting arms to the supporting claws 10a, 10b without using human hands, and can be easily and safely taken out, and can also be supported up to the bottom of the vertical base frame. Since it is carried by claws, the cloth shaft will not be damaged or make noise if dropped from a height.

(2) The cloth shafts taken out can be automatically moved and collected in the cloth shaft collection parts 4b, 4b only by circulation of the endless link chain.

(3) Since the cloth shaft collection parts 4b, 4b are provided protruding from the rearmost part, no human labor is required to take out the cloth shaft after the completion of rolling and to attach the cloth shaft for the next roll of cloth.
Moreover, it is not located below the rear end of the spreading machine body, which is dangerous.
This can be done safely and automatically in an open area.
