[Detailed Description of the Invention] (Technical Field) The present invention relates to an attachment for wrapping a band having a lever ring at one end and an engaging protrusion at the other end onto a member to be wound.

(Prior art) In order to fix a hose-like member to a pipe end, etc., a band as shown in FIG. 6 is usually used, that is, a band a having a lever ring b at one end and an engaging protrusion d at the other end is used. As shown in FIG. 7, after wrapping this around the hose-like member W to be fastened, the inner end c of the lever ring b is placed on the band a at the other end of the lever ring b, which is engaged with the engagement protrusion d. The band is folded down and tightened, and finally, the crimping pieces e and e provided on both sides of the other end of the band a are crimped onto the band a. However, this type of wrapping work requires most of the manual work, except for caulking work, so there is a limit to the amount of work that can be done, and there is also the problem that uniformity of wrapping cannot be expected due to individual differences. have.

(Purpose) The present invention was made in view of the above problem, and its purpose is to provide a novel band wrapping attachment that can automatically wrap a band uniformly. There is a particular thing.

(Technical Means for Achieving the Object) The present invention provides a band wrapping attachment for achieving the object, in which the inner end of a lever ring b provided at one end of the band main body is connected to the other end of the band main body a. In a device for tightening a band body part a on a member to be wrapped by reversing a lever ring b while engaging with an engagement protrusion d provided on the member, the band body part a is held in contact with the member to be wrapped. A band presser 7 is formed on the inner side of each band presser 7, and a curved portion is formed inside each of the band pressers 7, which is pivotally supported so as to be openable and closable using the rear of the band presser 7 as a fulcrum, and is capable of gripping a member to be wound. a pointed head 11 that pushes out the inner end of the lever ring b through the band main body part a in the winding direction of the band main body part a;
A guide 12 for preventing lateral slippage of the band body part a is formed on both outer sides of the band main body part a, and a protrusion 21 on the other end that abuts and causes the distal end of the lever ring b in the closed state, and this protrusion. A pair of clamp members 1 and 2 provided with guides 22 for preventing lateral displacement of the band main body part a formed on both inner sides of the part 21;
A lever 8 that is disposed opposite the raised lever ring b and is rotatable to push down the lever ring b onto the upper surface of the other end of the band body part a, and a band body part a that is wound around the member to be wound. and a caulking member 9 at the inner end of the lever ring b, which is disposed so as to be movable forward and backward facing the caulking piece e of the lever ring b.

(Function) With this configuration, the band body part a is brought into contact with the circumferential surface of the member to be wrapped by the band restrainer 7, and in this state, the band body part a is wound on the member to be wrapped. When the pair of clamp members 1 and 2 are closed as shown in FIG.
Push out the inner end of lever ring b in the winding direction,
The protrusion 21 of the other clamp member 2 contacts and raises the tip of the lever ring b, so the lever ring b is then pushed down onto the upper surface of the other end of the band body part a by the lever 8, and further advanced. The inner end of the lever ring b is crimped to the band main body part a using the crimping member 9.

(Example) Therefore, the details of the present invention will be explained below based on the illustrated example.

1 and 2 show an embodiment of the device of the present invention, in which reference numerals 1 and 2 refer to handle rods 13 and 23.
The left and right clampers are opened and closed in a scissor-like manner by opening/closing cylinders (not shown) installed in the clamps, and each operating end for band winding is formed to have a thickness approximately equal to the width of band a, and grips the object to be wound. They are curved inward to each other so that they can be moved. Of these clampers 1 and 2, the first clamper 1, which holds the lever ring b side of the band a, pushes the band a closer to the lever ring b to hold the inner end c of the band as shown in FIG. Point 11 for locking to the engagement protrusion d on the other end
The second clamper 2, that is, the clamper 2 that holds the engagement protrusion d side of the band a, has an arcuate protrusion that comes into contact with the tip of the lever ring b and acts to raise it. 21 is provided outward from the abutting portion of the pointed head 11, and band guides 1 are provided on both sides of the tip of the first clamper 1 and on both sides of the inside of the second clamper 2 to prevent the band a from shifting laterally.
2 and 22 are integrally attached. Reference numeral 4 denotes a moving table which is guided by a guide rail 51 provided on the base plate 5 and is attached to be movable forward and backward relative to the pole 6 for positioning and fixing the object to be wound. 2 is pivotally supported by a fulcrum bolt 3, and on the front side thereof, a band presser 7 having a magnet 71 for holding the band on its surface is connected to an adjustment screw 7.
It is attached so that it can be adjusted back and forth via the 2.

On the other hand, in the vicinity of the pole 6 for positioning and fixing the object to be wound, there is a lever ring b which is rotated so as to come into contact with the lever ring b raised by the clamps 1 and 2 and fold it over the upper surface of the other end of the band a. A lever 8 for pushing down a moving lever ring is pivotally supported, and guide rails 52, 52 extending on the board 5 toward the caulking pieces e, e of the band a have tapered portions 9 at their tips.
An air cylinder type caulking device 9 (FIG. 4B) equipped with an air cylinder 1 is mounted so as to be movable forward and backward by a cylinder device (not shown).

Next, the winding operation of band a using the above-mentioned apparatus will be explained based on FIG. 5.

At the beginning of the operation of the apparatus, the movable table 4 is retreated from the pole 6 for positioning and fixing the object to be wrapped, and both clampers 1 and 2 maintain a state in which they are fully expanded. At this stage, a new object to be wrapped is supplied to the pole 6, and a new band a is supplied to both clampers 1 and 2, and is held by the magnet of the band presser 7.

Next, the moving table 4 is advanced toward the object to be wrapped, and when the band a held by the band presser 7 comes into contact with the object to be wrapped, the moving table 4 is stopped and both clampers 1 and 2 are closed. Then, as shown in (b), band a gradually comes to be wound onto the object to be wound.

This winding operation of the band a takes place on the second clamper 2 side, and then moves to the first clamper 1. However, in the final stage of winding by the first clamper 1, the tip of the lever ring b is shaped like an arc of the second clamper 2. When the first clamper 1 is further closed by contacting the protrusion 21, the lever ring b is gradually raised by the peak 11 of the first clamper 1 and the protrusion 21 of the second clamper 2, and finally , E, the inner end c of the band a comes to engage with the engagement protrusion d at the other end.

When the lever ring b is raised in this way, the lever ring push-down lever 8 rotates clockwise in the figure to lightly support the tip of the lever ring b from the back side. Thereafter, the expansion of both clampers 1 and 2 and the rotation of the lever 8 proceed, and the lever ring b, supported by the protrusion 21 of the second clamper 2, rotates counterclockwise about the engagement protrusion d as a fulcrum. Finally, the other end of the band a is superimposed on the upper surface and tightened onto the object to be wrapped. After this series of operations is completed, the crimping devices 9, 9 move forward, and with the tapered part 91 pressed against the crimping piece e, the crimping member 92 pushed out by air pressure performs crimping, and all the parts are crimped. work is completed.

Although the above-described apparatus uses the magnet 71 as the means for attracting and holding the band a, this can be replaced with an equally effective means such as an air adsorption type. Furthermore, this type of attachment may not be fixed on the base 5, but may be attached to a robot to automate the work.

(Effects) As described above, according to the present invention, one clamp member 1 is provided with a pointed head 11 that presses the inner end of the lever ring b in the winding direction, and the other clamp member 2 is provided with a lever ring b. Protrusion 21 that causes b
At the same time, a lever 8 is provided to push down the lever ring b that has been pushed down to the band body part c, and a lever 8 that pushes down the lever ring b that has been pushed down to the band body part c
Since a caulking member is provided, by operating these in conjunction with each other, it is possible to uniformly and automatically attach the band body part a, which has a lever ring b at one end, onto the member to be wound. hand,
By replacing this type of difficult work that was previously left to manual labor with this simple device, a large amount of labor can be saved.
