Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cap insertion device for inserting caps into both ends of a winding core of a paper web cut to a specified size. Note that in this specification, the term "cap" includes not only metal caps, but also caps made of materials such as plastic and rubber.

As shown in FIG. 1, the paper roll is composed of a paper 2 wound around a core 1 to form a cylindrical paper roll 3. When carrying out cargo handling, a pipe may be inserted into the winding core 1, or the inlet portion 4 at the end of the winding core 1 may be inserted.
The winding core 1 is usually made of cardboard or the like, and is too weak to support the weight and easily breaks, so a cap 5 as shown in Fig. 2a and b is used. It is necessary to insert the roll paper 3 wrapped in wrapping paper 6 as shown in FIG. 3 into the inlet part 4 and leave it in the state shown in FIG. 4, thereby reinforcing the inlet part 4.

The cap 5 is inserted into the winding core 1 fairly firmly so as not to fall off during cargo handling or transportation, but conventionally, the cap 5 has been inserted manually by hammering using a jig. However, this method requires a lot of manpower (per roll of paper,
2 people on each side. For example, if this is 3 lines, 6
The disadvantages were that the working speed was slow, and there was a risk of damage to the paper roll due to improper handling.

Attempts have been made to automate the insertion of the lever, but it has been difficult to adjust when the web sizes are different.

The present invention detects the height of the top of the web, and in conjunction with this, raises and lowers the height of the cap holding mechanism so that it almost matches the height of the axis of the web, thereby solving the above drawbacks of the conventional one. The height of the cap holding mechanism is automatically adjusted to the axis height of the paper roll, even for rolls of different sizes, and the cap is inserted smoothly and reliably, making it highly efficient and highly efficient. The object of the present invention is to provide a reliable cap insertion device.

The present invention is a cap inserting device for inserting caps into both ends of a winding core of a paper roll, and includes the following configurations.

(A) A paper roll support mechanism that supports and holds the paper roll; (B) A cap holding mechanism that holds the cap; (C) A top height of the paper roll is detected, and the axis of the cap holding mechanism is adjusted according to the detected value. A cap height adjustment mechanism that adjusts the core height to approximately match the core height of the paper roll.

(D) a moving mechanism that reciprocates the cap holding mechanism in a direction parallel to the axis of the web; (E) a supply mechanism that supplies the cap to the cap holding mechanism.

To explain the present invention with reference to the drawings, in the plan view of FIG. , is supported between the receiving rolls 10 and 11 of the web support mechanism so that the axis is horizontal and oriented perpendicular to the transport direction of the arrow.

Inserters 12 and 13 are provided on both sides of the paper roll 9, and are adapted to insert the caps held by cap holding mechanisms 14 and 15 into both ends of the paper roll 9. Reference numerals 16 and 17 are parts feeders that feed the inserting machines 12 and 13 with the caps.

To explain the details with reference to FIGS. 6 to 9, reference numeral 18 is a base frame, and the insertion machines 12 and 13 are mounted on rails 19 and 20 provided on the upper surface of the base frame.
(13 is not shown in FIGS. 6 to 9) is movably mounted, and a cylinder 21 serves as a moving mechanism.
Accordingly, the inserters 12, 1 are inserted parallel to the axis of the web 9.
3 to move back and forth.

The insertion machine 12 (the same goes for 13) has two side plates 23 and 24 on both sides on a lower movable frame 22, and a horizontal shaft 27 is rotatably supported by bearings 25 and 26 on the upper surface thereof. It is rotationally driven by a cylinder 29 via a lever 28. 30, 31
is a stopper, which limits the rotation range of the horizontal shaft 27 to 90 degrees.

A guide plate 32 is fixed to the horizontal shaft 27 via a bracket 33. A rectangular guide hole 34 is provided in the guide plate 32 so that the cap holding mechanism 14 can move up and down while keeping the axis horizontal and not rotating around the axis. are guided by. At the tip of the cap holding mechanism 14, there is an expandable chuck 35 with a tapered tip and divided into three or four parts.
is provided, and the chuck 35 is inserted into the inner diameter of the cap 5 in a state where its outer diameter is contracted to the minimum, and the chuck 35 is expanded to hold the cap 5 in such a state that it is expanded from the inside.

A bracket 36 is fixed to the guide plate 32 and swingably supports a lever 37. One end of the lever 37 is pivotally connected to a cylinder 38 and is adapted to be driven. 39 is a lever, pin 40
It is swingably supported by the guide plate 32. The other end of the lever 37 and one end of the lever 39 are connected by a link 41 via pins 47 and 48, and the other end of the lever 39 and the base holding mechanism 14 are connected by a link 42 via pins 49 and 50. has been done.

A shaft 43 is fixed to the lever 37 and swings together. The vicinity of the other end of the shaft 43 is supported by a bearing 44, and an arm 45 is fixed thereto. A contact 46 is provided at the tip of the arm 45.

The contactor 46, the shaft 43, and the pin 47 are arranged substantially in a straight line and substantially parallel to the lever 39. In addition, the lever ratios are as follows: 43-46 distance: 43-47 distance ≒ 3:1 40-49 distance: 40-48 distance ≒ 3:2 It's becoming like that. If the swing range of the arm 45 is about ±30 degrees from the horizontal, the contactor 46
The movement of the rotation pin 49 is approximately vertical, and
Since the link 42 also maintains a substantially vertical direction, by driving it with the cylinder 38, the ratio of the lifting distance of the contactor 46 to the lifting distance of the cap holding mechanism 14 is approximately 2:1, and the cap height adjustment mechanism is formed.

In FIGS. 7 and 8, 51 is a gutter for receiving the ferrules 5 sent from the parts feeder 16, arranging them in a row, and supplying the inserting machine 12. When the cylinder 29 (FIG. 6) is extended, the guide plate 32 and the parts attached thereto rotate 90 degrees together with the horizontal axis 27, and the cap holding mechanism
4', the chuck 35' faces downward.
A base support 52 is provided at a position directly below this downwardly facing chuck 35', and is adapted to be raised and lowered by a cylinder 53. Base support 52
A recess 54 into which the cylindrical portion of the cap 5 fits is provided.

Next, the roll support mechanism will be described.
In Fig. 7, the receiving rolls 10 and 11 are supported by shafts 55 and 56, respectively, and are held by levers 59 and 60 which are rotatably supported by bearings 57 and 58. The levers 59 and 60 are swung by a cylinder (not shown) or the like, and the receiving rolls 10 and 11 are rotated by the levers 59 and 60.
The numbers 0 and 11 go up and down.

To explain the operation, in FIG. 9, the web 9 rolls on the guide path 7 and enters between the inserters 12 and 13. In this case, the receiving roll 10 is lowered to the surface of the guide path 7, and after the web 9 has passed, the receiving roll 10 is returned to its original height, so that the web is positioned at the center of the insertion machines 12, 13 with respect to the advancing direction. It will be done.

In parallel with this, or in advance, the caps 5 on the gutter 51 shown in FIG.
is raised and fitted into the chuck 35'. After the chuck 35' expands and holds the cap 5, the horizontal shaft 27 is rotated by the cylinder 29 (FIG. 6), and the cap holding mechanism 14 is rotated by the cylinder 29 (FIG. 6).
is in a horizontal position as shown by the solid line, and the base 5 held by the chuck 35 is positioned at the entrance 4 of the winding core 1 of the web 9.
to face.

There are several diameters of the paper roll 9, and the height of the axis of the cap holding mechanism 14 is adjusted according to the diameter by a cap height adjustment mechanism. For example, as shown in FIG. 9, a case will be explained in which the center of the paper roll is downward by an amount A with respect to the axis of the cap holding mechanism 14.

The insertion machine 12 has a cylinder 21 as shown in FIG.
is at the most compressed position away from the web 9. In FIG. 7, the axis of the cap holding mechanism 14 is shown to coincide with the axis of the web 9, but it is assumed that there is a difference A as shown in FIG.

Next, the cylinder 21 is extended, the inserter 12 approaches the web 9, and the contact 46 enters the web 9 from its end surface. At this time, if the gap between the contactor 46 and the top surface of the paper roll 9 is B, the dimensions of each part are determined in advance so that B≈2A. Next, when the cylinder 38 is retracted to bring the contact 46 into contact with the top surface of the web 9, the axis of the cap holding mechanism 14 is lowered by half the stroke of the contact 46, that is, by A, and the axis of the web 9 is lowered. It almost matches.

Then, the cylinder 21 is further extended,
The chuck 35 is fitted into the entrance portion 4, and the cap 5 is fitted. Thereafter, the chuck 35 is contracted, and the cylinder 21 is further contracted to return the inserter 12 to its original position. At the same time, the cylinder 29 is extended and the chuck 35 is returned to the position 35' to receive the next mouthpiece.

During this time, the receiving roll 11 is lowered, the receiving roll 10 is further raised, the web 9 is rolled onto the guide path 8, and is transferred to the next process by rolling or handling by a crane or the like.

The work is carried out by repeating the above steps.

In the case of a web 9' having a small diameter as shown in FIG.
When the cap 6 is brought into contact with the top surface of the paper web 9', the axis of the cap holding mechanism 14 substantially coincides with the axis of the paper web 9' due to the cap height adjustment mechanism.

However, because the contact 46 and the pin 49 form an arc, and there is a height difference of C between the lower ends of the large-diameter web 9 and the small-diameter web 9', the contact 46 may cause the web 9 or 9 to Although it is very difficult to detect the top surface of the base and align the axis of the cap holding mechanism 14 with the axis of the webs 9, 9', the error is small for the diameter range. The dimensions of each part, lever ratio,
It is preferable to choose the location of the fulcrum. The error can be taken up by the tapered part of the chuck 35.

The rotation angle of the horizontal axis 27 is not limited to 90 degrees, but may be any other angle. In that case, check 35' (Fig. 7)
faces not directly downward but in an oblique direction, and holds the nozzle 5 that is supplied from the oblique direction.

Further, the cap height adjustment mechanism may use another link mechanism, and is not limited to the link mechanism, but may also use a transmission mechanism such as a chain, gear, or belt, or a servo mechanism using hydraulic pressure, pneumatic pressure, or electricity.

The present invention provides a cap insertion device for inserting caps into both ends of a winding core of a web, which includes (A) a roll support mechanism for supporting and holding the roll, (B) a cap holding mechanism for holding the support, and (C) the above. a cap height adjustment mechanism that detects the top height of the web and adjusts the axial height of the cap holding mechanism to approximately match the axial height of the web according to the detected value; (D) the cap; A moving mechanism that reciprocates the holding mechanism in a direction parallel to the axis of the web, and (E) a supply mechanism that supplies the support to the base holding mechanism, thereby making it possible to handle webs of different sizes. To provide a highly efficient and highly reliable cap insertion device that automatically adjusts the height of a cap holding mechanism to match the core of the roll paper, smoothly and reliably inserts a support, and does not require human labor. This has an extremely large practical effect.
