2. Description of the Related Art Conventionally, as a device for wrapping a label around a rod-shaped article, there is one disclosed in Japanese Patent Publication No. 54-6878. That is, according to the invention disclosed in this publication, both ends of a rod-shaped article in the axial direction are gripped by a pair of disc-shaped pressing surfaces, and the rod-shaped article is rotated in a predetermined direction by causing both pressing surfaces to rotate in synchronization with each other ( Around the axial direction). Further, it has a means (roller) for locating the label in the vicinity of the side surface of the rod-shaped article and pressing the side surface, and while the rod-shaped article is rotating, the label is pressed by the pressing means. The label is wound by pressing it to the side.

[0003]

However, in the above-mentioned conventional apparatus, since both end surfaces of the rod-shaped article are held by the pressing surfaces, compressive stress is applied to the rod-shaped article in the axial direction, and In the case of an aggregate of fragile articles such as dry noodles (straw noodles) and incense sticks, if the gripping (holding) force is large, the articles may be damaged.
In the case where the rod-shaped article is composed of a large number of articles such as dried noodles and incense sticks, the end faces thereof are not aligned (flush), and some of the articles project. In such a case, the above problem becomes more prominent.

Further, since a pair of pressing surfaces are gripped from both ends of the rod-shaped article as described above and a predetermined pressure is applied,
The rod-shaped article concerned needs to be accurately placed at the center position between both pressing surfaces (if a displacement occurs, unnecessary force is applied and it causes damage), and the rod-shaped article is not wound around the winding device. The supply process becomes complicated. And, in reality, it is difficult to accurately position the center, and in order to suppress the damage at the time of gripping by the pressing surface, the both pressing surfaces are slowly advanced and gripped with respect to the end surface of the rod-shaped article. There is a need. Therefore, there is a problem that high speed operation cannot be performed.

Furthermore, unless the center of rotation of the pressing surface and the center of the rod-shaped article are aligned with each other, winding deviation occurs and the label cannot be wrapped neatly, and high precision is required for alignment between the devices. It

A basic structure is formed from the label clamped by the label clamp means and the article supply means for supplying the rod-shaped article to the winding mechanism provided in the main body of the winding device. The winding mechanism is fixed to a predetermined position of the winding device main body, and the other end of the winding belt is arranged to be windable, and the label and the rod-shaped article are loosened laterally at a predetermined position in the longitudinal direction of the winding belt. Means for forming a holding space, means for closing the article inlet side of the holding space to bring the label into close contact with the side surface of the rod-shaped article via the winding belt, and means for winding the other end of the winding belt. And consisted of

[0008]

The label holding means sends the label to the main body of the winding device and holds the label given by the holding means. Then, the winding belt located inside the label is provided with a predetermined slack to form a holding space, and the bar-shaped article is supplied into the holding space together with the label by using the article supply means. Next, holding space entrance (supply of goods)
The side is closed, the label is brought into close contact with the rod-shaped article, and the winding means is operated in that state to wind the other end of the winding belt. During this winding, the belt moves in the longitudinal direction,
The label that is in close contact with the belt, and the rod-shaped article that is in close contact with the inside of the label receive the biasing force in the moving direction, but are located in the closed holding space,
By rotating in the holding space, the label is completely wrapped around and fixed to the side surface of the rod-shaped article.

That is, in the present invention, since the rotational force applied to the label and the rod-shaped article is performed by the movement of the winding belt wound around the side surface of the rod-shaped article, the rod-shaped article is not subjected to an excessive compressive stress and the like. The winding process is performed smoothly and cleanly without damage.

Is brought into contact with the surface of the gluing roller 92, the glue attached to the surface is transferred to the label 11 side, and the gluing operation is completed.

Next, the operation of the above embodiment will be described. First, as shown in FIG. 2, the label sandwiching claw 22 located at the lowermost position of the rotary disc 21 is moved to the first plate cam 32.
Label opening device 15 to 1 when opened by
A label 11 is supplied and the tip of the label is clamped by the label gripping claw 2.
It is inserted and arranged in the space between 2 and the claw receiving member 31.
After that, when the rotary disc 21 rotates in the forward direction (the direction of arrow A in the figure), the label holding claw 22 is closed due to the relationship between the first plate cam 32 and the cam floor 29, and the leading end of the label 11 is moved to both sides 22, 31. Sandwich between. In that state, it rotates about 90 degrees in the forward direction.
1 is glued to a predetermined portion of the rear end of the rod-shaped article 10, the sandwiched label 11 faces the carry-out end side of the article supply device 16 and is arranged so as to interrupt the transportation of the rod-shaped article 10.
Then, in this state, the paper pressing plate 85 provided below the article supply device 16 is moved forward, and as shown in FIG.
The rear end of the label 11 is clamped between the front end 85a and the first clamping roller 49. As a result, the label 11 becomes
The leading end and the trailing end are respectively clamped at predetermined positions and are taut.

Then, the second plate cam 67 is rotated clockwise (in the direction opposite to the normal rotation of the rotary disc 21), and the cam surface 67a of the second plate cam 67 is connected to the label holding claw 22. By contacting the cam floor 29 and urging the cam floor 29 outward, the label holding claw 22 is opened to release the holding of the label 11 as shown in FIG.

Then, the plate cam 63 for controlling the swing of the swing lever 51 is rotated clockwise by a predetermined amount. Then, the relative movement between the cam floor 62 connected to the swing lever 51 and the cam groove 63a of the plate cam 63 causes the swing lever 51 to swing clockwise as shown in FIG. Loosen a certain amount. Then, the push-out pusher 82 is moved forward so that the rod-shaped article 10 at the tip end abuts on the label 11, and together with the label 11, the winding belt 40.
Is supplied into the holding space 95 formed by slackening the.

The tip 85a of the paper pressing plate 85 and the first
The plate cam 63 is further moved in the clockwise direction by a predetermined amount while maintaining the state where the rear end portion of the label 11 is nipped between the nip roller 49 of FIG. The moving lever 51 is further swung in the clockwise direction so that the second holding roller 52 provided at the tip of the swing lever 51 is brought into contact with the first holding roller 49. Then, the belt 40 is held in the holding space 95 where a predetermined portion of the winding belt 40 is pinched and blocked between the both nipping rollers 52 and 49.
The label 11 is located on the inner peripheral surface of, and the rod-shaped article 10 is located further inside. Then, the rear end portion of the label 11 is arranged so as to project outside the both nipping rollers 52 and 49. The leading end of the label 11 located in the holding space 95 in this state does not reach the position of the second nipping roller 52, but is separated by a predetermined distance.

Next, the paper pressing plate 85 moves backward to separate it from the rear end of the label 11, and the push-out pusher 82 also moves to the lower position and then moves backward to prepare for the next supply of the rod-shaped article 10 (see the same figure). (See (B)). Also,
Simultaneously with this backward movement, the rotary disk 21 and the plate cam 63
Rotate in the positive direction (counterclockwise) synchronously (at the same speed),
The winding mechanism 23 including the swing lever 51 and various rollers 49 and 52 also rotates in the forward direction. As the rotary disc 21 and the plate cam 63 rotate in synchronization with each other as described above, the relative positional relationship between the cam floor 62 provided on the swing lever 51 and the cam groove 63a of the plate cam 63 does not change. The bar-shaped article 10 and the label 11 supplied and held in the holding space 95 formed by the belt 40 are
It revolves around as supplied.

As a result, as shown in FIG. 6C, the lens is positioned at an angular position displaced by 90 degrees. Then, while maintaining this state, the rotation drive shaft 65 is moved forward so that the cylindrical auxiliary tool 66 provided at the tip thereof is matched with the cylindrical member 55 provided on the take-up roller 53, and then the rotation drive shaft 65 is moved in a predetermined direction. Rotate a predetermined number of times. Then, the rotational force is transmitted to the take-up roller 53 via the engaging projection 66a of the cylindrical auxiliary tool 66 and the cylindrical member 55 (engaging claw 55a), and rotates a predetermined number in the winding direction of the winding belt 40. . Then, the winding belt 4
Since one end 40a of No. 0 is fixed to the fixed rod 42 and cannot move, as the winding process described above progresses (C) in FIG.
The tension roller 44 moves to the outside in the radial direction, as shown in, and corresponds to the above-described winding process.

By the winding, the winding belt 40 is moved from the first holding roller 49 side to the second holding roller 5 side.
Since it moves toward the second side, the holding space 9 for the rod-shaped article 10
Label 1 that rotated in 5 and had its rear end protruding to the outside
The rear end portion 1 also enters the holding space 95, and the rod-shaped article 10
Along with that, it rotates in the holding space. Then, since the label 11 and the rod-shaped article 10 are rotated by the wrapping belt 40 in a close contact state, both ends of the label 11 are adhered to each other via the adhesive applied to the predetermined portion of the rear end of the label 11 by the contact pressure. This completes the winding process.

As described above, the tension roller 44
Is moved up to a predetermined position, the second photocell 72b
And sends a rotation stop command to the take-up roller 53,
As a result, the forward rotation of the take-up roller 53 is stopped, the tension roller 44 is prevented from moving upward more than necessary and is prevented from jumping out of the concave groove 41, and the rotational speed of the take-up roller 53 can be controlled. There is.

During the winding process, that is, when the winding belt 40 is wound around the winding roller 53, an excessive force is applied to each part of the winding mechanism 23, and particularly, the swing lever 51 moves counterclockwise. Although there is a risk that the nipping rollers 49 and 51 will move apart from each other, in the present example, the holding roller 71 suppresses the separating movement so that the winding work can be performed reliably.

When the winding process is completed, the pressing roller 71 moves upward to enable the rotation of the rotary disc 21, and the rotary disc 21 and the rotary drive shaft 65 are synchronized with each other about 90 counterclockwise. Rotate once. At this time, the rotation drive shaft 65 rotates in the reverse direction, which causes the winding roller 53 to rotate in the reverse direction and the other end 40b of the winding belt 40 wound up.
Pull out. Then, the pulled-out portion of the winding belt 40 becomes long and a margin is created, so that the tension roller 4
4 moves to the deepest part of the concave groove 41 by the elastic restoring force of the spring 47. And when it reaches the innermost part,
Detected by the photoelectric tube 72a, and sends a reverse rotation stop command to the drive motor that rotates the rotary drive shaft 63. As a result, the rotation of the winding roller 53 is stopped, and further pulling of the belt 40 is stopped.

At this time (when the rotary disc 21 is further rotated counterclockwise by about 90 degrees), the plate cam 63 is rotated in the opposite direction (clockwise) and sways as shown on the left side in FIG. The moving lever 51 swings counterclockwise. Therefore, the sandwiching rollers 49 and 52 are separated from each other, and the winding belt 40 between the rollers 49 and 52 returns to a taut state, and the product 96, which has been wound, is unloaded.

The rod-shaped article is not limited to the one formed of a large number of articles as in the above-mentioned embodiment, but may be a plurality of articles or a single article.
