The throttles (120), (121) are connected to the tips of the plungers (15a), (16a) of the air cylinder plunger devices (15), (16) at fixed positions.

The pleating process of the head of the container/wrapping paper in the illustrated embodiment of the apparatus of the present invention is as follows.

The wrapping paper to be treated is previously wrapped around a cylindrical container (a) in the state shown in FIG. 7, and the wrapping paper is wrapped in such a manner that at least a portion of the overlapping portion is glued. The winding and adhesion treatment may be performed by any suitable method known per se.

The container (a) wrapped with this wrapping paper is vertically oriented by a suitable method, for example a conveyor system known per se, with the container head side facing the vertical folding device (1). It is carried into the predetermined position of the pleat applicator (1) and stopped. The conveyor is designated by (17) and the cradle for the container (a) is designated by (18).
As shown in the figure. When transporting this container (a), the vertical pleat folding device (1) is such that the core (2) is
), but is retracted to a position corresponding to occupying a position far to the right in FIG. 1 with respect to the container head (a'). The container (a) on the pedestal (18) is held by the presser foot (1) from above.
9) and is held between this and the pedestal (18). The retainer (19) is driven by an air cylinder plunger device (20). cradle (18) and presser foot (19)
The container (a) held between the containers (a) and the core (2) are aligned in accordance with a predetermined design.

Next, add vertical folds to the side of the container (a) (
1) is driven together with the movable frame (4), and the forward motion accompanying this drive causes the core (2) to move against the container head of the cylindrical body (b) made of wrapping paper wrapped around the container (a). (a'
) and the container head (a)
′). When this penetration reaches a suitable degree, the vertical pleat applicator (1) is stopped.

When the core (2) enters the space, the presser rod (3
) occupies a position corresponding to the outer side of the zone (C) of the wrapping paper tube (b).

Further, the inner space of the core (2) is placed under negative pressure through the suction pipe (10). With the stoppage of the core (2),
The presser rod (3) is attached to the band (c) of the wrapping paper tube (1).
(See the chain line in Figure 1).

When the core (2) has entered, the lever (9) is rotated in a predetermined direction by the air cylinder plunger device (6) using the slide block (7) as a working medium, and the presser rod (3) is accordingly rotated. From the point facing the outside of the zone (C), toward the trough (5) on the circumferential surface of the core (2).
) (strictly speaking, it moves in a convergent manner until it contacts the bottom of the trough through the wrapping paper tube). With this convergent movement, the holding rod (3) is moved to the core valley (
Press the part corresponding to 5) onto the core valley (5). The presser is under the condition, that is, under the convergent state, and the tip (30) of the presser rod (3) protrudes forward beyond the front end (left end in Figure 1) of the core (2). , container (a)
is in contact with the shoulder (a″) of.

When the above operation is completed, the presser rod (3) is in the convergent state,
That is, while remaining in contact with the bottom of the core valley (5), the vertical pleat folding device (1) is moved in the opposite direction of the double series, and as it moves, the pressing rod (3) is pressed against the core. (2) and set back to band (a').

In this way, the zone (C) of the wrapping paper cylindrical body (b) is pressed against the core valley (5) by the presser rod (3).
By retracting the core (2) and the presser rod (3) from the zone (c), the vertical pleats are processed, ie, crimped, and the zone (a') is formed with vertical pleats.

As mentioned above, the pleat drawing process of band (C) is performed on the core (3
) and the presser rod (3) extending along the core valley (5), the pleat drawing is carried out in the band (C) without causing any wrinkles or damage other than the pleat drawing. Ru. Also, during this pleat drawing, negative pressure is applied to the inner space of the core (2),
Since the inside of the zone (C) is also under negative pressure through the inner space of the core (2), vertical folds are easily formed in the zone (C), and if the results of the pleat drawing treatment of the zone (C) are good. Close.

0) traces the shape of the container shoulder (a''). Therefore, the vertical pleat drawing is performed in a manner that closely follows the shape of the container shoulder (a''). It is obvious that it is advantageous to automate the edge folding process of the vertically pleated grooved zone (a') if the longitudinal pleats are formed in accordance with the shape of the container shoulder.

The tip of the presser rod (3) is apertured (110) (111),
(11B) (114) When the above-mentioned squeezing process proceeds until it retreats slightly to the right in Fig. 1 from the corresponding location, then the pedestal (
18) and the presser foot (19), while holding the container (a) with the pleated wrapping paper, the air cylinder plunger devices (13) and (14) are used to squeeze the container (110) (
111) (11B) and (114) are driven to squeeze the neck of the vertically folded and rubbed band (a') of the wrapping paper tube (b) from the surroundings, and apply the crimped and rubbed part (e) to the neck of the band. . During processing, the front end of the core (2) is still in the zone (a') and the core is inserted into the zone (a') according to a predetermined design during processing. (2) Place under negative pressure through the inner space. Therefore, the narrowing pattern (e) is effectively performed.

When the tip of the presser rod (3) retreats slightly to the right in Figure 1 from the location corresponding to the squeezer (12) (12), that is, close to the tip of the wrapping paper (the right end in Figure 1), the air The squeezer (
12) (12) is driven, and the constrictor (12) (12) is driven.
), the apertures (120) and (121) of the wrapping paper container head (
Band (a') protruding from a') to the right in Figure 1
Squeeze from the top and bottom of Figure 1.5. In accordance with the design, this narrowing occupies a location offset from the vertical central axis of the container head (a') as shown in FIG. It is done in a closed manner.

The narrowing process of the band (a') at this deviation point is performed by narrowing the band (a')
') The above-mentioned narrowing pattern (e) on the neck, together with the processing, makes automation of the edge folding process of the band (a') more convenient.

After the above-mentioned pleat drawing process is completed, the presser rod (3) is returned to the state before the convergent movement, that is, the state in which it is open with respect to the core (2), by the air cylinder◆plunger device (6). The negative pressure load on the suction tube (10) may be released at an appropriate time after the pleat drawing process.

The bottom (d-) of the wrapping paper tube (b) on the container (a) is
It is preferable to carry out the folding process using a conventional method at an appropriate point until the above-mentioned pleat drawing process is completed.

After processing, the aperture (110) (11
1), (113) and (114) are returned to their pre-driving positions by air cylinder plunger devices (13) and (14),
After the squeezing process, the squeezing device (12) (12) is returned to the position before driving by the air cylinder plunger device (15) (16).

After the above-mentioned processes have been completed, containers with wrapping paper are placed in a presser (19) in preparation for the next pleating process on the top of the container/wrapping paper.
It is released from the suppression and is discharged from the system.

Effects of the Invention As described above, according to the present invention, not only can the folding process of the head of container and packaging paper be performed using mechanical force without causing wrinkles or damage other than the folding process, but also the edge folding process can be automated. As a convenient mode for measurement, longitudinal pleats can be applied.
