Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention runs an endless tenter chain along left and right tenter rails, and stores a strip in a pin plate pin fixed to the links of the tenter chain. In a tenter for strip-shaped articles which is configured to hold and transport a strip-shaped article under tension by locking the ears of the tenter, there is provided a tenter for locking the ears of the strip-shaped article to a pin of a tenter chain on the entrance side of the tenter. This invention relates to a pinning device.

[Prior art and problems to be solved by the invention] In a conventional pinning device, an upper rubber roller with a brush roller attached to the outside in the axial direction is provided inside the end portions of the strip supply side of the left and right tenter rails, and is movable up and down. The brush roller was attached to the top surface of the pin plate of the tenter chain, and the upper rubber roller was attached to the top surface of the belt-shaped article slightly inside the pin plate. Furthermore, a lower roller was provided below the upper rubber roller to sandwich the strip and support the upper rubber roller from below.

In this pinning device, in order to lock the ears of the strip to the pins of the tenter chain, after adjusting the interval between the left and right tenter rails, the upper rubber roller with the brush roller attached is raised, and the strip is moved higher than the lower roller. Guide it to a slightly backward position. At this position, the tips of the ears of the strip are pushed into the pins of the tenter chain, and the pins are passed through the ears. Then, the upper rubber roller is lowered to nip the edges of the strip. If the tenter chain is made to run in this state, the strip-like objects held by the tenter chain will be carried in the same direction. In front of the brush roller, this strip-shaped object rests on the tip of the pin, but when the strip-shaped object is rolled up by the brush roller, the strip-shaped object is pressed from above by this brush roller. , the pin passes through the ear of the strip.

However, in order to pass all the pins through the ears of the strip,
The reality is that the brush roller attached to the upper rubber roller alone is not sufficient.

In other words, if the pinning device is as described above,
Some of the pins of the tenter chain do not penetrate the ears of the strip. This makes it impossible to transport the strip while keeping it taut.

Therefore, in order to solve this problem, it has become necessary to provide a wider contact surface between the brush roller and the strip.

In addition, a second auxiliary rubber roller is installed in the direction in which the upper rubber roller moves along the strip.
There is a pinning device in which the brush roller and the third brush roller are provided so as to be movable up and down, thereby providing a wider contact surface between the brush roller and the strip. The belt-shaped material is not only provided on the brush roller provided on the upper rubber roller, but also on the second
By passing through the brush roller and the third brush roller, the number of pins penetrating the strip becomes larger than before, but in this case, the pinning device inevitably becomes larger.

Furthermore, it is very troublesome to replace worn brush rollers because there are a large number of brush rollers.

Furthermore, in the pinning device having the above-mentioned configuration, it is necessary to raise and lower the brush roller each time a work is started or finished, which is time-consuming.

[Means to solve the problem] Therefore, the present inventor took the following measures.

The present invention runs endless tenter chains on both sides of a strip, the links of these tenter chains fix a pin plate, and the pin plates are provided with pins for locking both ears of the strip. , a tenter for a strip-like material is provided, in which lower rollers are arranged below both sides of a traveling strip-like material, and upper rubber rollers are provided above the lower rollers so that the edges of the strip can be held between these lower rollers. In the pinning device, a pulley is coaxially connected to the upper rubber roller,
A support wheel is provided in the direction of movement of the strip of this pulley, and a brush belt with brushes implanted on the outer surface is installed between the pulley and the support wheel located above the pin, and an upper rubber roller is installed near the pin. The brush belt is placed at a position where it comes into contact with the upper surface of the strip, and the strip is sandwiched between the upper rubber roller and the lower roller and is pressed by the brush belt, thereby pinning the strip.

Furthermore, the above-mentioned pulley, support wheel, and upper rubber roller are integrally configured to form a pinning device main body, and by providing this pinning device main body so that it can be raised and lowered, the upper rubber roller, pulley, and support wheel can be raised and lowered integrally. It is preferable to

[Function] In the pinning device of claim 1, when the pulley or the support wheel rotates, the brush belt rotates accordingly.

The ends of the left and right ears are pushed into the pins of the tenter chain in advance to lock the strip, and the strip is run as the tenter chain is driven. The strip is
The strip is sandwiched between the upper rubber roller and the lower roller and wound around the rotating brush belt, whereby the strip is pinned by the pins of the tenter chain located below the brush belt.

In this way, the pins of the tenter chain are used to lock the ears of the strip at long intervals, such as from the pulley to the support wheel.

As a result, not only is the belt-shaped object completely locked by the pin, but there is no risk of the pinning device becoming too large. Furthermore, even when the belt becomes worn, the time required to replace it is shortened.

Further, in the pinning device according to the second aspect, when the pinning device main body is raised and lowered, the upper rubber roller, the pulley, and the support wheel are simultaneously raised and lowered integrally. This results in
Elevating and lowering the rubber rollers at each start and end of work requires no effort, as it is only necessary to move the pinning device body up and down.

[Example code] Hereinafter, one embodiment of the present invention will be described based on the drawings.

Furthermore, guide rails 23 are provided at both front and rear ends of the pinning device body 20 to guide the device body 20 up and down. The pinning device main body 20 also includes a motor 24.
The output shaft of this motor 24 extends in a direction perpendicular to the running direction of the strip. A pulley 26 and an upper rubber roller 28 whose diameter is slightly larger than that of the pulley 26 are sequentially attached to this output shaft. Therefore, this motor 2
4 rotates the output shaft, and the pulley 2B and the upper rubber roller 28 rotate accordingly.

Reference numeral 30 denotes a support wheel located behind the pulley 2B and having a smaller diameter than the pulley 28. The support wheel 30 is pivoted on a shaft extending inward from the device main body 20 so that the height level of the lower end of the support wheel 30 is the same as that of the pulley 28 on the inner surface of the device main body 20. There is. Further, the circumferential surfaces of the pulley 2B and the support wheel 30 are provided with recesses having the same width so that a brush belt, which will be described later, can be attached thereto.

Reference numeral 32 designates a brush belt, which consists of a synthetic resin belt body and flocked hair on the outer surface of this belt body. This brush belt 32 is installed on the pulley 2B and the support wheel 30 using the recess. This results in
When the pulley 26 rotates, the brush belt 32 installed between the pulley 2B and the support wheel 30 rotates. Further, when the main body 20 of the apparatus is moved up and down by the air cylinder 22, the motor 24, pulley 26, upper rubber roller 28, support wheel 30, and brush belt 32 are moved up and down along the guide rail 23 as one unit.

A support shaft 34 extends from the inner surface of the tenter rail 10 in a direction perpendicular to the running direction of the strip A. Reference numeral 36 denotes a lower roller rotatably supported by this support shaft 34.

Further, reference numeral 38 indicates a support shaft 34 from this lower roller 3B.

and a pulley 52.

The second support arm 48 is pulled downward by the traction of the spring 54, and this is connected to the first support arm 4 via the shaft 50.
6. As a result, the pulley 52 is pulled downward. Thereby, the belt 56 can always be maintained in a tensioned state.

The support plate 38 also has a pivot shaft 58 at its rear lower end.
One end of the lower air cylinder 60 is attached to the inner surface of the tenter rail 10, and the other end of the lower air cylinder 60 is pivotally supported by the pivot shaft 58. The operation of the lower air cylinder 60 causes the support plate 38 to rotate about the support shaft 34 . In other words, the lower air cylinder 60 allows the belt roller 42 and the pulley 52 to move up and down together.

Next, the usage condition of this pinning device 2 will be explained.

In order to lock the ears of the strip A to the pins 18 of the tenter chain 12 using this pinning device 2, first, the interval between the left and right tenter chains IO is adjusted. Then, the air cylinders 22 are driven to raise the left and right device bodies 20. Along with this, the upper rubber roller 28, the pulley 26,
Support wheel 30 and brush belt 32 rise. Also,
The left and right belt rollers 42 are lowered using the lower air cylinder 60. This state is shown in FIG. This makes it easy to hold both sides of the front end of the strip with hands, pass it between the upper rubber roller 28 and the belt roller 42, and guide it to the rear of the lower roller 36. Then, the front end of the strip A is pushed into the pin 18, and the pin 18 is passed through the ear to lock it. Thereafter, the upper rubber roller 28 and belt roller 42 are raised and lowered to their original positions. As a result, the edges of the strip A are nipped. If the tenter chain 12 is run in this state, the front end will be attached to the pin 18 of the tenter chain 12.
The strip A that is locked to is automatically conveyed in the same direction. The arrow in the figure indicates the traveling path of the strip A. As mentioned above, the left and right tenter chains 12 circulate outside the pinning device 2, respectively.
The tenter chain 12, which has run from the rear of the pinning device 2 in the opposite direction to the running direction of the strip A, is moved by the upper rubber roller 2.
8, it changes direction and runs parallel to the strip A. Therefore, the pin 18 of the tenter chain 12 fits under the ear of the strip A at the lower end of the upper rubber roller 28. After the strip A is wound around the upper rubber roller 28 and the lower roller 3B, the ear portion of the strip A is sandwiched between the brush belt 32 and the pin plate 14 that supports the pin 18, and the lower edge portion of the strip A is The pin 18 located at
It will pass through the ears of this strip A. As the strip A continues to travel, the pins 18 successively pass through the ears of the strip A, thus pinning the strip A and keeping the strip A under tension. It can be held and transported as it is.

According to this pinning device 2, the pin 18 locks the strip A over the surface of the brush belt 32 that comes into contact with the strip A. In other words, the above-mentioned locking is performed by the pulley 26
This is done at longer intervals than in the past, such as from the lower end to the lower end of the support wheel 30. As a result, the pins 18 can completely lock the ears of the strip A, and there is no risk of the processing machine for the strip A becoming too large.

Furthermore, even when the brush belt 32 is worn out,
Compared to the conventional example, this can be replaced easily. Furthermore, as mentioned above, when starting or finishing work, the upper rubber roller 28 and the pulley 2 can be moved by simply raising and lowering the device main body 20.
6 and the support car 30 can be moved up and down, so it does not require much effort.

Note that in this embodiment, a belt 56 is installed over the lower roller 36, belt roller 42, and pulley 52 below the running path of the strip A, but this belt 56 is not always necessary and can be omitted. . In this case, the pulley 52 for tensioning the belt 56 becomes unnecessary.

All other embodiments that fall within the scope of the claims are within the scope of the present invention.

[Effects of the Invention] In the pinning device of the first aspect, the pins of the tenter chain lock the ears of the strip at long intervals, such as between the pulley and the support wheel. This allows the pin to completely lock the belt-shaped object, eliminates the risk of it becoming too large, and even when the belt wears out,
The time required for this exchange has become shorter.

Further, according to the second aspect, the upper rubber roller, the pulley, and the support wheel are raised and lowered integrally by simply raising and lowering the pinning device main body, so that no effort is required when starting or finishing the work.
