[0005]

According to the present invention, there is provided an apparatus for providing a tubular member made of a long flexible material from a flexible material, the device being rotatable together and being displaced radially from an axis. A cutting station comprising a rotor and means for rotating the rotor about the axis; and displacing the elongate material longitudinally through the guide to cause a free end portion of the material to protrude from the guide. Means and a member of a predetermined length which is arranged for relative rotation of the rotor and which engages during rotation of the associated rotor and the material in the guide of the rotor. A cutter for cutting from the free end portion of the material, and in order to cut the next material after the cutting, the displacement means indexes the material and displaces the material in a longitudinal direction; The free end of the Apparatus for providing a tubular member made of the flexible material of a flexible material elongate, characterized in that protrude from Id is provided.

Further in accordance with the present invention, there is provided a method of providing a member comprising said material from an elongated, flexible material, said member being elongated through said guide in a rotor such that a free end portion of said material protrudes from said guide. Displacing the elongated material in a direction and rotating the rotor about the axis with the guide displaced radially from the axis such that the free end portion of the material is disposed on a circumference. And cutting the free end portion from the material and forming the member from the material while cutting the free end portion of the material on the circumference while placing the free end portion of the material on the circumference. And providing a member made of a pliable material.

In accordance with the present invention, the flexible material is typically supplied in a continuous form from a drum or reel,
A circular displacement is applied to its free end by the rotor,
While the circular displacement is applied, the material passes through a cutter that cuts the member from the edge of the material. With such a technique, by properly synchronizing the indexing of the material passing through the guides of the rotor so that each member is of a predetermined length, the members are sequentially and relatively fast in a simple and efficient manner. Cutting at speed. Furthermore, rotating the rotor at a high speed is more easily achieved and easier to control than the reciprocating blade-type cutters conventionally proposed for cutting material to a predetermined length. Yes,
It has been shown to be more reliable. A length of material is flexible enough to allow its free end to be rotated by the rotor without affecting the desired properties of the material, and e.g. a longitudinal direction for indexing the material through a guide by rollers. It has a moderate rigidity that enables the displacement of Further, depending on the attitude of the device, for example, in a configuration in which the member is vertically displaced so that the free end discharges while being upright from the guide, the free weight of the free end portion (cut to form the member) may be reduced. The material must have sufficient rigidity to support As mentioned above, the present invention has been developed for use in cutting members from small diameter plastic tubing and, for convenience, will be described with respect to that use. Alternatively, it can be effectively applied to other types of materials such as a single fiber made of plastic.

Although the rotor rotates intermittently, for high speed production, it is preferred that the rotor rotate continuously, usually in each case for each rotation of the rotor. One member is cut from the free end of the supplied tube.

[0009] Preferably, the supplied tubing is arranged in the track section to displace the tubing longitudinally toward the guide. The track portion has an end that is generally coaxial with the axis of the rotor and axially spaced from the rotor so that during its longitudinal displacement, the supplied tube moves along the track portion, At the end of the track portion, it is radially displaced from the track portion by the length of the portion between the guide and the track portion. In such an arrangement, the supplied tube is longitudinally displaceable through a guide tube which is rotatable with the rotor, providing communication between the track portion and the guide.

[0010] The cutter preferably has the shape of a cutting edge or cutting blade with which the plastic tube to be cut engages while the rotor rotates. The cutting edge is mounted so that it is indexed to provide a new cutting edge portion to the tube when other portions wear. If desired, during rotation of the rotor, the cutter provides a circular cutting edge and is driven to rotate continuously or intermittently about its axis.

[0011] Preferably, a retaining means is provided for engaging the free end of the supplied tube for cutting the tube between the guide. The retaining means has the shape of a claw or jaw that initially engages the free end of the supplied tube and then retains the portion to be cut from the tube. The holding means forms part of the transfer means which engages with the free end of the supplied tube to transfer the portion cut from the supplied tube to the predetermined station, discharging from the guide.

[0012] The transfer means described above is preferably synchronized to engage the free end of the supplied tube just before the supplied tube is cut. In a preferred arrangement, the transfer means comprises a turret which rotates about an axis remote from the axis of the rotor and which arranges the holding means described above in a circular shape, a part of which is provided with a circular circumference. Tube passes through an area substantially coincident with a portion of the circumference of a circle arranged so that the rotor and cutter cut the tube. During the rotation of the turret, the holding means is adapted to engage the supplied tube when the holding means enters the area and holds the cut tube member from the area for transfer to a predetermined station. Synchronized. The axis of the turret is generally parallel to the axis of the rotor. To facilitate high-speed processing of the tube member, the turret is provided with a plurality of holding means, such as jaws or claws, arranged in a circumferentially-spaced array and a turret around the turret. And a plurality of cutting stations arranged in the same manner, the tubing emanating from each cutting station being held by holding means selected to be synchronized with the respective cutting station.

[0013] To facilitate automatic mechanical processing of the tubing cut from the supplied tubing, the tubing transferred to the predetermined station by the transfer means is engaged with the components forming the assembly. A member arranging means for arranging the members is provided. The locating means is configured to displace the tubing from a predetermined station to attach the tubing to a particular component or to place the tubing on or within a particular component. For example, the tube member (or other member if not of tubular shape) is positioned and held by a positioning means on a component held by glue or welding. However, in a preferred configuration where the tubing is attached to the hollow insert to grow foam in a beverage package of the type described above, the tubing is press-fit into the seating of the components of the insert. Then, the free end of the tubular member is treated to be engaged by the locating means such that it is press-fit into the socket port of the insert or into the tubular plug of the insert.
The locating means engages the tubing at a predetermined station of the transfer means and engages the tubing with a particular component;
Or it has holding means for transporting it for placement on or in a particular component (or, if the transfer means comprises holding means, another holding means is provided). The holding means of the positioning means comprises claws or jaws for holding the tube member. If the transfer means includes holding means such as claws or jaws, another holding means of the locating means may be a tube transferred by the transfer means to a predetermined station before the holding means of the transfer means releases a particular tube member. Preferably, they are synchronized to engage the members. If the transfer means comprises a rotatable turret as described above, the locating means may provide a second turret rotatable about an axis remote from (and usually parallel to) the axis of the turret of the transfer means. It is preferred to have. With such a configuration,
The holding means of the locating means are arranged in a circle, a part of the circular circumference on which the holding means is arranged extends through another area which generally coincides with a predetermined station of the transfer means, and the other area In order to carry a particular tube member to the mounting station while the second turret rotates, the transfer means of the transfer means is released before the particular tube member is released from the holding means of the transfer means to the holding means of the positioning means. The holding means of the second turret are synchronized to engage the tubing held by the holding means, and at the attachment station, the tubing engages with a particular component, such as the package insert described above. Or placed on or in a component. The second turret has a plurality of holding means, such as claws or jaws, or another plurality of holding means arranged in a circumferentially spaced array, the holding means comprising: ,
It is arranged to sequentially engage a series of tubing members located at a predetermined station of the transfer means for sequentially transporting the tubing members to the attachment station. The locating means comprises seating means displaceable with the locating means, the seating means being for transporting and arranging the components supplied by the tubular member carried by the retaining means of the arranging means.
With this in mind, the above-described turret of the positioning means comprises an array of circumferentially spaced sheets associated with each of the holding means of the turret, the components being positioned by said sheeting means. Is supplied with a tube carried by the associated holding means of the sheet. For example, each sheet transports and positions an open-headed container in which an insert into which a tubular member is to be press-fitted through an opening by displacing the holding means is disposed. Preferably, the open headed container is generally cylindrical and has a seating in which the tubing is press fit so as to be positioned substantially coaxially with the axis of the container within the container, the positioning means comprising: A probe that is displaceable in the open container and displaces the end of the tube member in the axial direction of the container to press-fit the tube member with the sheet. Such an arrangement would be axially displaceable in the container such that the free end of the tubing engages the sheet to accurately position the axis of the container with respect to the desired line of displacement of each probe. As such, it is beneficial for the cylindrical container to be placed on the sheeting (and therefore, to ensure that the placement of the free end of the tube member is properly aligned to engage the sheeting, the This eliminates the need to rotate the container in the circumferential direction, or to rotate the position of the insert with the sheeting within the container).

The container 40 with the insert 43 attached and in an upright position is conveyed by a conveyor 50 and star wheels 51 so as to be accommodated in a sheet 52 held by a horizontal platform 53 of the placement unit 3.
(Rotating counterclockwise in FIG. 3). The platform 53 is driven by a drive unit (not shown) about a vertical axis 54 separated from the axis 7 and the axis 21 by an arrow 5 in FIG.
Rotating clockwise, indicated by 5. Twenty sheets 52 are provided on a platform 53 spaced about a circumference about an axis 54. A turret 56 that rotates about an axis 54 in harmony with the seat 52 is disposed on the platform 53. The turret 56 holds twenty tube mounting heads 60 spaced on a circumference about the axis 54 and each positioned directly above the sheet 52. The head 60 is attached to the lower end of a vertical rod 61 with a rolling cam follower 62 engaged with the lower track of a cylindrical fixed core 64 of the placement unit. During rotation of the turret 56 and the sheet 52, the cam follower 62 passes through the cam track 63 to impart a vertical displacement to the rod 61 and the head 60, and for each rotation of the turret 56, the head 60
Performs a vertical displacement at a predetermined cycle.

Each head 60 has a vertical probe 70, and the lower end of the vertical probe 70 has a radius (similar to the control unit 24 of the holding unit 22) that is opened and closed by the control unit 72 of the head. A pair of jaws 71 facing outward in the direction are held. During rotation of the turret 56, the jaw 71 of the head 60 is displaced along a common circle centered on the axis 54, which partly coincides with the transfer station 31 of the transfer unit 2.

The member 30 is released. The jaw 71 of the head 60 engages the tube member 30 at the lower end of the tube member at the transfer station 31 and rises vertically (controlled by the cam follower 62 and the cam track 63) with the head 60 and the head 60 And head 60
Provided below the lower end of the tubular member 30 held by the container 40 is sufficient space for the container 40 to be accommodated in the sheet 52.

The axis of the seating 44 of the container and its insert 43 is aligned with the head 60 associated with that particular sheet.
The container 40 is transferred by the star-shaped wheel 51 and accommodated in the sheet 52 so as to be coaxial with the lower end portion 30 </ b> A held by the tube member 30. While the turret 56 and the sheet 52 rotate integrally, the transfer station 3
Since the tube member 30 carried by the head 60 from the head 1 is displaced vertically downward while being controlled by the cam follower 62 and the cam track 63, the probe 70 of the head 60 moves the opening 4 of the container disposed under the head.
2 and displaces the lower end 30A of the tube member along the axis of the container. Due to the continued rotation of the turret 56 and the vertical downward displacement of the head, the lower end 30A of the tube is pressed into the seating 44 of the insert 43, as shown in the right part of the placement unit 3 in FIG. Mated. The seating 44 of the insert is either in the form of a socket to which the lower end 30A of the tubular member is attached or in the form of a plug in which the lower end 30A of the tubular member is received. After the tube member 30 is attached to the sheeting 44, the jaw 71 is opened (while held in the container 40) to release the tube member 30 while the rotation of the turret 56 and the sheet 52 continues, and the head is moved from the transfer unit 2. As it approaches the transfer station 31, which is ready to receive the next tube member 30, the head 60 rises vertically upward from the container. By placing the seating 44 along the axis of the cylindrical container 40 and displacing the lower end 30A of the tubular member into engagement with the insert 43, the insert 43 and the container 40 are displaced.
Alternatively, it is evaluated that the container 40 and the sheet 52 do not need to be rotated in the radial direction to be aligned. After attaching the tubing 30 to the insert 43 and retracting the probe 70 from the container, the container is moved from the sheet 52 to the conveyor 50 by the star wheel 80, and the conveyor 50 connects the beverage filling station and the container closing station. Transferred in order.

When the open-headed container is fed into the seat 52 of the platform 53, the pipe member 30 is attached to the open-headed container sequentially so that the transfer unit 2 and the placement unit 3 are attached. The head 60 is synchronized. For convenience of explanation, the container 40 of FIG. 3 is arranged on a sheet 52 arranged below the head 60 of the transfer station 31.
However, in a practical embodiment, and as apparent from FIG. 3, the jaw 71 of the head 60 located above the seat 52
However, after lifting the tubular member 30 from the transfer station 3, the sheet 52 receives the open-ended container, and the container with the tube 30 attached thereto by the star wheel 80 before arriving at the transfer station 31. 52, the head 6 associated with that particular sheet
0 passes through the transfer station 31 and
