DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cap supporting device for a capper according to the present invention will be described with reference to the drawings.

The capper to which the apparatus A according to the embodiment of the present invention is applied is, for example, a container b for storing liquid such as chemicals, detergents and foods.
In the filling and packaging industry, the cap c is attached to the mouth of the container b.

As shown in FIG. 5, the apparatus A receives the caps c from the supply means d and delivers them one by one to the capper e, and FIGS. 1 to 4 and 6 to 6.
In the case of the first example shown in FIG. 10, the base body 1, the locking body 2,
It is basically configured by the operating means 3.

The above-mentioned substrate 1 is in the vicinity of the capper e,
For example, a frame (not shown) in the capper e is rotatably hung from the gripper f in the capper e and the other side thereof, and has a substantially horizontal mounting surface 1a at its upper part.

The above-mentioned locking bodies 2 are attached to the base body 1 and engage with the inside of the cap c, respectively, and are formed in a plurality of, for example, in a substantially circular plane shape as shown in FIGS. It is divided into two parts, or as shown in FIGS. 6 to 7, it is divided into four parts, and further, not shown, such as three parts, and the outer part is engaged with the inner peripheral part of the cap c. The respective arcuate abutting portions 4 are provided so as to match each other.

Therefore, by engaging the abutting portions 4 and 4 of the locking bodies 2 and 2 with the inner portion of the cap c, the cap c is stable and the core is displaced from the gripper f. Will be supported without.

The above-mentioned actuating means 3 is linked to the locking body 2 so as to make the locking body 2 movable in the radial direction of the cap c, and FIGS. 1 to 4 and 6 to 7 As shown in FIG. 8, all of the locking bodies 2, 2 ... Are operated relative to each other, or as shown in FIG. , 3 or more locking bodies 2
In the case of, one or more of them are targeted. ) Is activated.

In the case shown in FIGS. 1 to 4, a pair of locking bodies 2 and 2 are shown, and a screw rod 6 having a symmetrical screw portion is attached to a bearing 5 provided in the lower portion of the base body 1. Screw 6
Locking bodies 2 and 2 that are screwed into the respective screw portions are attached via a moving groove 7 of the base body 1, and a knob 8 provided at one end of the screw rod 6 rotates the screw rod 6 in the forward and reverse directions. As a result, the locking bodies 2 and 2 move forward and backward in the moving groove 7, and
From a minimum inner diameter L1 of the cap c as shown in FIG. 2 to a relatively large diameter Ln of the cap c as shown in FIG. 2 and FIG. The distance between the abutting portions 4 and 4 of the locking bodies 2 and 2 is adjusted so as to obtain.

In addition, in the case shown in FIGS. 6 and 7, the locking body 2 formed in a plane circular shape is divided into four parts with the center point thereof as a reference, and the locking body 2 is radially inserted into the base body 1. Interlocking members 10, 10, 10, 10 such as bevel gears are attached to the inner ends of the four fitted screw rods 6, 6, 6, 6 so as to mesh with each other and interlock with each other, and one of the screw rods is attached. The knob 8 is fixed to the outer end of the knob 6.
Thus, by rotating the screw rod 6 in the forward and reverse directions, the locking bodies 2 and 2 advance and retreat, and the distance between the contact portions 4 is changed.

The rotation drive of the above-mentioned screw rod 6 can be performed not only manually by the knob 8 but also by mechanical automatic operation of a motor, a fluid cylinder or the like.

Further, FIG. 8 shows an example in which only a part of the locking body 2 moved by the operating means 3 is operated by the pair of locking bodies 2 and 2. One of the locking bodies 2 is fixed to the base body 1, and the other locking body 2 is fixed.
Is movably inserted into a moving groove 7 provided in the base 1.

The lower part of the other locking body 2 is screwed into a screw rod 6 supported by a bearing 5 provided on the lower side of the base 1, and a knob attached to the outer end of the screw rod 6. By the forward and reverse rotation of the screw rod 6 by the operation of 8, the movable locking body 2 is arbitrarily brought into contact with and separated from the fixed locking body 2, and the contact portions 4, 4 thereof are
Adjust the interval of.

Further, in the case shown in FIGS. 9 and 10, the forward / backward guides 1b in which the lower sides of the pair of locking bodies 2 are projectingly provided on the base body 1 are shown.
The conical pressing body 6a is brought into contact with the inner ends of the locking bodies 2 and 2, and the pressing body 6a is moved by the rotation of the screw rod 6 screwed onto the base 1. As a result, the locking bodies 2 and 2 relatively open and close to accommodate various cap diameters, and the rotation operation of the screw rod 6 is performed by the knob 8 attached to the outer end portion thereof.

Incidentally, the retreat (return) of the pair of locking bodies 2, 2
Is performed by a spring 2a linked to each locking body 2,2.

Next, FIGS. 11 to 13 show another embodiment apparatus A, which is basically the same as the above-described embodiment apparatus A and includes a base body 1, a locking body 2 and an operating means 3. The locking body 2 and the actuating means 3 are different.

The locking body 2 is made of an elastic material fitted to the outer ends of a plurality of advancing / retreating pins 12 which are fitted substantially horizontally into the projection 11 provided on the base 1 so as to be movable in the radial direction. The locking body 2 is capable of expanding and contracting in the radial direction of the cap c.

An operating means 3 including a conical pressing body 13 and an operating member 14 such as a screw rod for moving the pressing body 13 forward and backward is linked to the inner end of the forward / backward pin 12.
By attaching the knob 8 to the outer end portion of the operating member 14 and rotating the operating member 14 in the forward and reverse directions by this operation, the forward and backward moving pins 12 on all directions move forward and backward at the same time. The body 2 relatively expands or contracts around the axis of the operation member 14, so that the inner diameter of the cap c can be changed.

The actuating means 3 in this example is made to correspond to the pressing body 13 so that one or a plurality of advancing / retreating pins 12 (1 to 3 out of 4 in this embodiment) are actuated. For example, only a part of the locking body 2 causes expansion / contraction motion, and it is possible to freely adjust the interval with respect to the change in the inner diameter of the cap c.

As shown in FIG. 13, the actuating means 3 is composed of a pressing body 13 for pressing the locking body 2 and an operating member 14 such as an air cylinder for moving the pressing body 13 back and forth. And the cap c for this locking body 2
At the time of attachment, the pressing body 14 is retracted by the air cylinder 14 and the locking body 2 is contracted to the minimum through the advancing / retracting pin 12, and a gap is formed between the cap c and the locking body 2. , When the cap c is attached, the air cylinder 14
Is operated to advance the pressing body 13 to bring the locking body 2 into contact with the inner peripheral portion of the cap c.

The engagement of the locking body 2 with the inner peripheral portion of the cap c is performed by a predetermined pressing force by the air cylinder 14 (a pressure that does not adversely affect the cap c and can reliably hold the cap c). However, an arbitrary size is locked within the stroke range of this cylinder, and it is not necessary to perform troublesome adjustment for each different cap c.

Further, since there is no gap (play) between the locking body 2 and the inner peripheral portion of the cap c, the cap can be held reliably.

The air cylinder type actuating means 3
It goes without saying that the above can also be adopted in the actuating means 3 shown in FIGS. 1 to 4 and 6 to 10.

[0037]

According to the present invention constructed as described above, since the locking body which engages with the inner circumference of the cap is movably provided by the actuating means, there are many kinds of caps having different inner circumference diameters. Since it can also be used for supporting the cap, the changing work at the time of changing the mold can be performed instantly and easily, and the dimension adjustment according to the inner circumference of the cap can be performed with high accuracy.

Since a separate supporting device for each shape of the cap is not required, storage and management thereof are not required, and capping processing at low cost can be performed. And so on.
