Description

DETAILED DESCRIPTION OF THE INVENTION It has been known for some time that various containers, such as containers for dispensing kelp, particularly ice cream products, can be formed from various plastics.

Certain well-known container materials are made from paper products as well as plastic materials. A known container of this configuration is a so-called push-out cup consisting of a generally cylindrical outer part provided with a movable plunger in its interior. This internal plunger has several rods that allow the user to push out the contents of the push-out cup as it is used. Extruded cups are made not only from paper but also from well-known injection molding techniques. In the past, extrusion forces could not be successfully produced from polystyrene beads because of the need for greater strength than that available with polystyrene beads.

In the past, the formation of Steam Chess 1 (steam chest) type cups required such cups to be constructed with fairly thick sidewalls and edges in order to provide adequate strength and stiffness as well as surface finish.

As a result of this increased sidewall thickness, it is not possible to package as much product in seven container cans as would be possible if the sidewalls were relatively thin.

Therefore, there is a need for materials that are more desirable in terms of overall storage and relative strength.

Extruded paper containers have a certain degree of strength when the paper is dry, but the container quickly loses its strength when the paper is immersed in a wet product.

Another disadvantage of the so-called Steam Chess 1 molded extruded container is that, as a result of its manufacturing method, the decoration of the external side of its side wall can only be carried out after the extruded container has been manufactured. The required decoration and printing techniques after such manufacturing are
Printing techniques, such as flexo printing, used before assembling various sheet materials into cup-shaped containers are also considerably slower and more expensive. As a result, many steam chest molding units currently on the market do not have decorated exterior surfaces simply because the decoration must be done after the cup is manufactured.

In addition, cup 0 and cup-shaped containers can be produced by cutting a suitable fan-shaped blank from a sheet material and forming it into a cylindrical container using techniques well known in the field of manufacturing paper cups and ice cream foods. It is made from plastic filler. This method of manufacturing containers allows the side walls of the container to be decorated while the plastic or paper material is in the form of a sheet and prior to cutting out the rectangular side wall blanks. By controlling the density of such plastic or sheet materials, containers can be made with suitable strength, stiffness and liquid-tight properties, and with fairly thin side walls, such as those of steam chest molded cups. Also,
Such large number It is now possible to decorate containers in a manner that has become very common in commerce.

A unique disadvantage of such containers is that they form a back ridge at the bottom of the extrusion container. This particular glue rough 0
The shape requires the material to be moved over a considerable distance, thus causing the material to tear or crack and significantly reduce the strength of its surroundings. Another type of insulated or thermoplastic foam container, which has some commercial success and whose structure is extrusion force, is somewhat similar to ``deep draw force'', which is a seamless unit made by well-known thermoforming techniques. , is Zo. Such cups can be made to extremely close tolerances and with excellent stacking characteristics as required. Even with thermoformed deep-drawn containers, the decoration must still be done after their manufacture.

As is clear from the foregoing discussion, each of the well-known types of insulating containers mentioned above has unique advantages for some applications, while others are less suitable than others. It has restrictions that make it .

Other types are currently possible in the manufacture of extruded containers. This particular insulated extruded container combines a wide range of desirable properties and does not suffer from the limitations found in paper convex containers. This new type of extrusion container is suitable for a wide range of applications for insulating extrusion cups.

The side walls of such containers can be formed from rectangular blanks, thus resulting in a large amount of scraping and excessive cost, as in cutting specially shaped container side wall blanks from a sheet metal or web of material. There is no need for A beautiful, high-quality decorative design can be applied to the side wall of such an extruded container at a relatively low cost. Furthermore, if desired, such a cup can be provided with a very slight chirage to improve the movement of the cilantro contained within the reservoir which moves the food upwards. Relatively inexpensive, high quality extruded containers are made from rectangular blanks. The side walls of the extrusion vessel are formed from a web of polystyrene or other thermoplastic polymer sheet material with a considerable degree of orientation or heat shrinkability produced in the so-called longitudinal direction of the material web. A decorative material is applied to the oriented web of material and the printed web is cut into long strips each containing a repeating pattern of individual container blanks. This strip of material is then cut into individual container blanks, which are formed as cylindrical sleeves with the longitudinal direction of the base web being circumferential around the extruded sleeve 9. The gaps in the sleeve formation are provided with a liquid-tight lap seam using heat or solvent roll techniques. A sleeve winding mandrel is used to form the extruded sleeve to the desired diameter and form the necessary side beams. The finished sleeve, when not formed in-situ on this mandrel, then has an outer forming surface, whether the sidewalls are generally straight or tapered, as in a cup or extrusion container. is placed on a mandrel corresponding to the desired shape of the inner surface of the container side wall. A portion of this sleeve is cantilevered by the free end of the mandrel when a rim is required to be formed at the bottom of the extrusion container or the entire bottom thereof. The other portions of the sleeve are heated to conform to the shape of the outer surface of the mandrel.

The production of monolithic extruded containers according to the present invention is effective in providing containers that can be used for frozen or semi-frozen foods. Yoshimoto Motoyoshi's containers can also be used for foods that are not frozen and have a semi-liquid consistency. The apparatus for producing monolithic containers according to the method of the invention includes a drum mechanism that moves in an arcuate path and has a number of spaced apart mandrels. Each mandrel has an outer shape that corresponds to the inner ring and shape of the extrusion vessel. The drum supports additional mandrels through a series of operational subassemblies that function in a timed sequence of interrelationships with respect to the mandrels to form the container of the present invention. Each individual mandrel, in addition to rotating with the drum, rotates about its own axis to wind a flat web of sheet material into a cylindrical sleeve. The method and apparatus of the present invention allows extruded containers with unexpected properties to be produced at relatively low cost and at high production rates.

Since the operation of the apparatus according to the invention is continuous, its operation is extremely smooth and good production rates are obtained during the manufacture of containers.

A seventh object of the present invention is to provide an apparatus for manufacturing campfire-shaped containers.

Another object of the invention is to provide a machine for producing extruded containers made from foamed plastic material.

These and other objects are achieved by the present invention in providing a rotary machine for manufacturing extruded containers from thermoplastic silastic material that shrinks in a controlled manner under the action of heat. A further feature of the present invention is to provide a method and apparatus for thermally manufacturing extruded containers from rectangular blanks of oriented thermoplastic plastic material without wasting any portion of such blanks. be. More specifically, the present invention features a method for manufacturing a container from a rectangular blank of oriented thermoplastic silicic material, which comprises forming the bottom rim of the extruded container substantially simultaneously with the other portions of the container. An object of the present invention is to provide a method and apparatus.

Containers of various types, particularly in the form of disposable cups, have been manufactured by various techniques and types of machines. Seven such container manufacturing machines are covered by U.S. Patent No. 351' Otsu 777.
It is illustrated and disclosed in No. 3 (dated July 73, 2007). According to this machine, a rectangular blank of foam sheet material is rolled into a cylindrical sleeve. A blank of sheet stock is fed to a sleeve winding station where the sleeve is wound onto the outside of a hollow cylindrical sleeve winding mandrel. The finished sleeve is then transferred to a shrinking mandrel where it is shrunk to the contour of the mandrel under the action of heat. In this particular case, a bottom closure is provided adjacent to the edge of the sleeve just before deflation, providing a bottom for the container. The container, including the bottom, is then passed to a rim forming station where a conventional heated rim is formed on the container. The finished container is then removed from the shrinking mandrel. Some related container forming apparatus for the extruded containers of the present invention are shown in U.S. Pat. A cylindrical sleeve is formed from a predecorated rectangular blank by introducing the tip of a rectangular notebook into a vacuum suction device formed in a vertical sleeve winding mandrel. The blank is then wrapped around a mandrel until its leading and trailing edges are in an overlapping position. Heat is then applied while applying pressure to form a liquid-tight seal along the length of the cylinder. The cylindrical sleeve is placed into the sleeve and continued heating causes the cylindrical sleeve to contract in a controlled manner into a container.

A subsequent pre-rim forming station completes the container by forming six regular rims in the form of a bead.

The completed container is released from a shrinking mandrel. U.S. Patent No. 397,011-7
(date) creates sealed overlapping ends by directing heated air between the ends of a rectangular sheet of thermoplastic material to soften the opposing surfaces and crimp these ends to form a boom. A method of manufacturing a container is described in which the material is formed into a tubular shape. A two-part container can be formed by sealing a disc-shaped bottom member of foam material to the ends of the side walls, and the ends of the trenched side walls are collapsed and fused to form the bottom of the container. A unitary container can be formed by closing and shaping.

Another related U.S. Pat. No. 37,937≠θ, dated February 7, 2007, discloses an article in the form of a container made from a cylindrical sleeve with overlapping seams. Disclosed herein is a two-piece or one-piece container.

US Patent No. ≠07.2! ; ≠ (dated March 7, 2007) describes an apparatus and method for manufacturing containers made from cylindrical sleeves. Although the shape of this particular sleeve is conventional, it is wound on a mandrel with the longitudinal axis oriented horizontally.

U.S. Patent No. 70g3177 (dated 797g) discloses a monolithic container. The container is made by projecting a sleeve of oriented sheet stock from the end of a shrinking mandrel and forming a long neck of small diameter. A subsequent pinching operation closes this long neck, removes the resulting turbulence, and by pressing down on the bottom a container is obtained, into which a rim can be formed by conventional techniques.

Yet another technique and apparatus for manufacturing containers made from foam sheet stock is disclosed in U.S. Pat.
March 78). A circular y-shaped sleeve is formed on the mandrel and a bottom closure is provided within the sleeve which is bent by one end of the sleeve. The sleeve and pre-installed bottom closure are heated while on the mandrel on which they are wound, and the sleeve is shrunk to conform to the shape of the mandrel. Subsequent pressure applied to the bottom of the container completes the 7-hole gap between the bottom of the closure and the side wall of the container. Yet another method for forming containers from rectangular sheets of foamed material is disclosed in U.S. Pat.
0211-Japan/Brazil). In this type of container manufacturing process, rectangular blanks are cut from the continuous strip 0. The blank is then transferred at right angles to its original direction to a long, stationary mandrel where it is folded substantially continuously about its center on the mandrel as it moves under and along the mandrel. The finished sleeve is combined with an end closure, placed on a shrinking mandrel and then formed into a container under the action of heat.

Another form of container forming apparatus is disclosed in pending U.S. Patent Application No. 09
．． 2g'92 (filed on July 7, 1997). The device of this particular invention includes a frame body that supports a motor 1 drive drum that rotates along a central axis of rotation and stops at predetermined arcuate intervals. The drum supports a radially arranged row of shrinking mandrels.

A seamed sleeve of oriented plastic material is preformed and telescopically mounted on a mandrel that projects radially from the drum. A portion of this sleeve projects beyond the free end of the mandrel. The mandrel and the sleeve coupled thereto are transported through an arcuate path where the sleeve is subjected to selective heat treatment by an adjacently mounted heating element and the oriented sleeve is moved through the mandrel in a controlled manner. It is shrunk to a shape corresponding to the outer surface. The portion of the sleeve cantilevered beyond the end of the mandrel is contracted into a small diameter tubular structure which is closed by the compressive action of the bottom pinch mechanism. Following closure of the bottom of the heat-softened sleeve,
The mandrel supporting the sleeve is moved to a work station where a pinched bottom mandrel is pressed against the end of the mandrel to form a liquid-tight bottom for the sleeve. The force utilized in forming the bottom of the container is also used to form an inverted rim on the container.

The mandrel supporting the finished container is then indexed against a discharge station 7, where the finished container is removed from the formed mandrel.

As is clear from the foregoing discussion, while each type of container made of insulating plastic material has certain advantages that make it suitable for certain applications, it also has certain limitations that make other types of containers suitable for other applications. less suitable.

The device according to the invention is suitable for producing monolithic extruded containers. This container can be made into a cylindrical shape if necessary, but it is originally in a cylindrical shape. The present invention includes a frame body that supports a laminated motor-driven drum so that it rotates about a central axis of rotation and stops at predetermined arcuate intervals. This drum supports a series of radially oriented shrinking mandrels. Each contraction mandrel is rotatable about its own axis. A ribbon of oriented plastic material is fed to each mandrel at a loading station. A predetermined length of plastic material is cut from this ribbon.
It is then wound by the rotation of the mandrel around a shaft which is held in place by the mandrel and is sent along an arcuate path by the movement of the drum against which the mandrel is supported. As the mandrel and associated sleeve are transported through the arcuate path, the sleeve is subjected to a predetermined heating which causes the sleeve to conform to the shape of the outer surface of the mandrel. Additionally, the portion of the sleeve that extends beyond the mandrel is contracted around the end of the mandrel and softened to facilitate formation of the bottom rim of the extruded container. After forming the bottom rim of the extruded container, the container is ejected from the mandrel and transported by fluidic means to a work station separate from the apparatus of the invention.

5-2 is the fifth drum assembly shown in the figure.
Although it is not shown in the diagram, the mandrel j is a foam sheet material! The leading edges of the webs are shown in their positions in the reservoirs. The foamed sheet material O2 is supplied from an O-ru (not shown) which is not part of the present invention. The foamed notebook material is first subjected to a preheating zone indicated by O3 and O≠, and is heated to +δ. The foamed notebook material is passed between preheating members 3 and 4 where the heat is applied to these sheet materials so that it easily transforms into a corpse which is wound onto a mandrel. supplied to The heat applied to preheating parts Otsu 3 and Otsuhiro is due to these parts Otsu 3 and Otsu≠
It can be engaged by electrical resistance wires embedded in it or provided on its surface. Foam sheet material B!
is advanced intermittently against the mandrel. This intermittent movement of the foam sheet material is controlled by gripping the sheet material by its upper edge and advancing it through preheating members 3 and 4.

In FIG. 5, the gripping mechanism 4 is shown in its fully advanced position just prior to releasing the foam sheet material. This grip @ structure is supported by support rods 4 and 7 installed in parallel.

The sliding support block 7.2 is also attached to the support rods 4 and 7 so as to reciprocate together with the gripper. The two clamping pawls 73 and 7 and the control arm 73 are rigidly flanged against the torque rod 7/ as it moves through the gap between the support plates 7 and 70.

Next, Section 4, which is a cross-sectional view taken along line Otsu-6 in FIG.
By referring to the figures, the actual sequence of operation of the gripping mechanism Oj will become clearer. The clockwise movement of the torque rod 7/ causes the clamp claws 73 and 7≠ to release the foam sheet material! from a position of contact with the outer upper side edge of. The completely separated or open positions of the clamp claws 73 and 7≠ are indicated by broken lines at 7B. The control arm 73, which is also fixed to the torque rod 7/, moves together with the clamping claws 73 and 7≠.

As shown in FIG. 4, the control <H+ arm 7, . As 5' moves in the clockwise direction, the lower forked end of the control arm 7j causes the small pawl mechanism 77 to rotate counterclockwise about its support rod 7. This small finger mechanism 7

g is attached to the lower end of plate O and 7o as shown in the second figure. When the door/door is moved counterclockwise, the crank 0 claws 73 and 7≠ move relative to the surface of the foam sheet material O2. Similarly, counterclockwise rotation of the control arm 7g biases its lower end against the small pawl mechanism 77 and causes it to rotate counterclockwise about the support rod 7g, thereby causing the small pawl contact opposite edges of the foam sheet material. In this position, the gripping mechanism holds the foamed silt material in place as the overall movement of the gripping mechanism moves it along its linear path along the support rods 6 and 7. can only be moved.

The cam follower 3 allows the push rod 3 to reciprocate forward and backward without rotating. The second cam follower is fixed part 4. t/f, 2 to give the relative movement to the bushing rod/30.

Cam followers 7, 1g3 and /I15>/ and their interaction with the cam 1 drive mechanism will be described in further detail below.

FIG. 20 is a perspective view of the intermediate plate /j seen from the front.

The position of drum assembly 5.2 is indicated by dashed lines.

Although the stationary shaft 3'l is shown partially in section, this shaft actually extends over the entire length of the drum assembly Ij, 2. A cylindrical cam track Schilling/g' is provided coaxially with respect to this shaft 3≠.

The cam track cylinder is attached to the intermediate plate by a fastener (not shown). The cam track cylinder cylinder gB has a cam groove /g7 formed on the end face on the side farthest from the intermediate plate /j. The cam grooves 7 have a uniform depth and are coaxial. The cooperating cam follower is not subject to direct movement from the cam groove/17.

The cam groove /g7 merely serves to stabilize and position the cam follower.

Referring again to FIG. 79, the right end of the figure shows a cam follower 77g connected to the upper door 15.2. This particular port controls the opening and closing of the finger mechanism 733.

The cam follower 77g cooperates with the cam grooves / and 7 shown in FIG. The interaction between the cam follower 77 and the cam groove/door is shown in the upper cross-section of FIG. In FIG. 20, three movable cam truck parts that are interlocked with the cam truck cylinders are shown. A first movable cam track section is attached to the end of the arm. This arm/ll;
'0 is attached to the end of the shaft. The second cam track section 79.2 is attached to the end of arm 793, which in turn is attached to the end of drive shaft/941. A third cam track section is similarly attached to an arm 7 which is similarly angled in several places relative to the drive shaft 7. During the operation of the entire device 10, when the cam follower 77g reaches the vicinity of the cam groove /Kg, the cam follower moves to the cam groove /77g.
The upper torque rod should move out of its normal path!
Rotate. After a slight rotation in one direction, the cam follower 77 relative to the upper torque rod/3.2 returns to its normal position and until the cam follower 77 reaches the second cam follower portion 77.2. Cam groove/g7
can move along an arcuate path controlled by. The camcorder hole 77g moves radially upwards again from its normal path, i.e. groove /g7. The upper l.r.k.o./32 rotates again and opens the finger mechanism 733. It is clear that in this way the upper torque rod /j,2 is actuated in three specific positions. Their specific location with respect to the overall sequence of operation of device 10 will be discussed further below.

In FIG. 20, a second cam track cylinder/9g provided inside the cam track cylinder cylinder gB is shown. This second or inner cam track cylinder 79g is attached to the surface of intermediate plate /j by a fastener (not shown). The cantilevered or forward end of the cam track sill/button is provided with a groove, 200. The groove 200 is the shaft 3 provided at the center position.
/I- and the depth of the groove 200 does not change, so the cam follower /g/ maintains a constant relative position as it moves along the circumferential direction of the groove 200. The cam follower /g/ is shown on the right side of Figure 1 and in the upper section in Figure 1. The cam follower /f/ is attached to the lower torque rod /j/ by a crank arm /0 and this port controls the discharge collar mechanism /≠g. cam follower/lr/
As it travels along a circular path in groove 200, the cam can contact and disengage from groove 200, thereby pivoting lower torque rod /j/. The cam followers / and / then return to the groove 200 again. The cam tractor 20/ is attached to an arm 202 which is attached to the end of a drive shaft 203. The movement of the drive shaft 203 will be explained later. As the cam follower unit moves along the arcuate path of the groove 200, it reaches the second cam follower section, 2011-.

This cam track section 20 is connected to an arm 20, which is attached to the end of the shaft. The shaft 20 will also be explained later. In this way, the lower dowel clock, D/R/, rotates by a specific amount controlled according to the amount by which the cam track portion, 20/, moves radially outward from the groove 200. I will do it.

In this case, the cam track portion 20/ is moved by a small amount. On the other hand, the cam track part, :zolJL
moves by a greater amount, thus causing the lower dowel clock, do 15/, to rotate through a greater angle. This large amount of rotation causes the discharge collar /17-g to move over the entire length of the mandrel jO, thereby causing the foam cylinder /30 to be discharged from the mandrel /jO.

The cam track cylinder ♂, which is coaxially provided in the cam track cylinder ♂, has another cam groove, 2.
07, and this groove is provided on its outer cylindrical surface. The cam groove 207 includes a cam follower 7g3- shown on the right side of Figure 1. Come Follower-i! i's is written several times in Butschrod/Yu0. The depth of the cam groove 207 is constant, but the depth of the intermediate plate /j

The intermediate plate /j is shown on the right side of FIG. 27, and the back plate /o is shown on the left side of the same figure. In the upper left part of FIG. 27, the cam gear ≠ and the shaft 1I-7 connected thereto are shown. These mechanisms are also shown in FIGS. 2 and 3.

The shaft≠7 spans between the intermediate plate /j and the back plate /o, and there the two cam wheels are mounted. It is shown with a large cam wheel Ir1.20f. Further, a shaft is shown in the upper part of FIG. 27. The shaft /ri/ is connected to the arm /ri0 at its right end. Arm 70 is shown in FIG. 20 with its cam track portion. 27th
In the figure, the shaft /ri/ is the cam follower arm, 210
It has been shown that it is combined with The cam follower arm 210 is cantilevered so as to move back and forth with respect to the cam wheel 20jY. The cam follower 2// cooperates with the cam groove 2/2 (see FIG. 2).

When the cam follower 2// reaches a part of the cam grooves 2/, 2 where it deviates from the coaxial path, the arm /90 is rotated so that the arm /90 pulls the cam track part /gg out of the groove /g7. Release and raise. As before, this opens the finger mechanism/33.

The cam wheel 2/B is attached to the drive shaft 3g as shown in Figures 2.7 and 2. When the cam wheel 2/B rotates under the action of the drive shaft 3g, the cam follower 27≠ rotates the arm 2/3 at an appropriate time, which in turn rotates the torque shaft 3g.

Rotation of the shaft causes arm 3 to rotate as well, thereby separating cam track portion 92 from its normal engagement with the cam track sill.

As the cam track portion 79.2 moves radially outward, the finger mechanism /33 is actuated again to move the fins /3
Do not remove / from the position close to the surface of the mandrel.

This movement also causes the finger mechanism/33 to open in the manner described above.

Referring again to Figure 20, the inner cam track cylinder has two cam track sections that control the movement of the ejection collar. o/ and 20≠ are provided. The first cam track section, 2.0/, and the linkage coupled thereto will now be described. Referring to Figure 127, shaft 203 is shown at the bottom of the figure.

The movement imparted by 22≠ rotates the shaft, 20, thereby causing the arm, 203, to deviate the cam track portion 20≠ from its normal position within the cam track cylinder/9. Cam track part, 20≠ is the cam track part! 0/, thereby effectively causing the emitting collar /4# to travel a much greater distance until it reaches its position /A/ as shown in Figure 1j. . When the discharge collar /≠ moves to this end position, the foam cylinder /30 is discharged from the mandrel.

When rotating the entire drum 32 in a counterclockwise direction when viewed from the front thereof, the second station, which is 4'5-0 when viewed counterclockwise from top dead center, is the first station where the mandrel is centered on its long sleeve. The rotation of the foam cylinder/30 is completed and timed to the point where it is in place for sealing. Heat is not only applied to the edges of the cut foam sheet material, but also to the face of the foam sheet material before it is cut by the knife processor 7 and the knife 10/. . A heating on-off device is used to properly distribute heat to the heat seal area of station 2.

Figures 2j and 2j are perspective views showing a mechanism for controlling heat distribution. The mechanism includes a valve mechanism that supplies heat to the heat supply nozzle 230. The valve mechanism in the plenum chamber 2.2g is a reciprocating Zono/Eronodo 2

The mechanism previously described is also shown in Figure 2, which is a perspective view of the push rod 24'7 and the mechanism controlling it. Franz 0 bar, 2jg is attached to 217. A hole in which the pin 2jO is provided in the clamp bar 2≠g; 2. ! ; / is collaborating with. When the pin, 2≠7, moves back and forth along its axial path, the movement transmitted through its pin, 2j, causes the heating clamp bar mechanism, 2j, 2 to become the pivot support shaft! It revolves around Yu 3. This bar mechanism, 2
As j2 rotates, its tip 2j≠ comes into contact with the preheated edge of the foam cylinder/30.

Fig. 27 shows that when the mandrels are located at their stations, the mandrels are moved in the radial direction along the axial line of the mandrels when the mandrels are moved counterclockwise by 0 from the top mandrel position. FIG. 3 is a partial cross-sectional view looking inside. When the already mentioned Gunoshirondo-2/I-7 moves back and forth, the clamp bar 2≠ cooperates with the pin 2jO. The pawl, 2J-O, engages the pin 230 and is biased from the other end by a spring, . In this way, even if a foreign object is removed, the seal per assembly will be removed for 2 days!
This mechanism will not be destroyed even if the chip accidentally falls between the chip 2 and the mandrelta. The seal bar assembly, 23.2, is provided with a series of holes through which a refrigerant is circulated to maintain the temperature of the chip at a temperature below which the foam cylinder/30 foam sheet material will not stick. This is done to keep it constant. Also shown in FIG. 27 is a heat supply nozzle 230 led from the plenum chamber 22f.

This heat supply nozzle 230 supplies a gas medium to the foam cylinder/300 split joint. Fingers /3/ are shown in position relative to the leading edge of the foam sheet material.

After the foam cylinder/30 has been sealed along its sides by the heated pars assembly 1, 2 and the tip 2, the mandrel is rotated through position 3 to position G. Position ll is located at a point moved counterclockwise from top dead center by /3 0. In position ≠ the release collar /1l-I moves partially along the longitudinal direction of the mandrel 5, thereby causing the foam cylinder /30 to project slightly beyond the end of the mandrel 5. Heat is optionally applied to the end of the cylinder/30 at this station. The foamed cylinder at this specific position is then conveyed by the mandrel to station j, which is at a position of /0° with respect to the top dead center. At stations j and station o heat is also applied to the cantilevered free end of the foam cylinder/30. Due to the inherent orientation of the particular foam sheet stock used for apparatus 10, the ends of the cylinder/30 shrink to a smaller diameter under the action of heat. The heated and softened foam cylinder/30 is then moved to station 7, which is moved 270° counterclockwise from the top dead center.

FIG. 37 is a partially sectional perspective view showing the drilling pin 27j in its fully retracted position and the ejection collar 7ug in its fully extended position at the free end of the mandrel. A completed cylinder/30 containing a small orifice, 27, has been ejected from the mandrel and is about to be sucked in by the air tube, 277. The foam cylinder is then transferred to a storage container remote from the overall device 10.

Referring again to FIG. 37, the foam cylinder/30 is inserted into the holding basket 27 just before it enters the air pipe, 277.
It is dropped in g.

In most cases, the foam sleeve/30 will fall into the receiving basket 27g when it is completed, but some of the foam cylinders/30 will stick to the punching die 27g and be freed. There is a risk that it may not fall into the 27g basket. In order to reliably remove the foamed cylinder 103 from the punching die 275, the third. ．． The mechanism shown in Figure 2 is used. In FIG. 32, a structural member 2711I- is shown in a horizontal position. A rod support bracket, 2zO, is attached to one end of the top surface of the structural member 27≠. A similar rod support bracket, 2g/, is attached to the other top surface of structural member 271I-. Support rods 2 and 2 are mounted in holes at the ends of rod support bracket 2♂0 and 2♂0. In this way, the support rod 2g2 can rotate freely even though it is held in place by the rod support brackets, 2gO and 2g/. A pivot arm, 2g3, is secured to a support rod, 2g3, and cantilevered upwardly therefrom. Ushida support arm, 2. f≠and,2g,! ; is supported Rondo 2
It is attached to the gno.

A pusher 2g B is suspended between the arms 2g≠ and 2dj. Further, 7 is attached to the support bracket 2 on the upper surface of the structural member 2711-, and rod support brackets 2 and 2g are attached to the upper surface of the structural member 2711-.
It is located between /. Support rod 2g2 passes through a hole in support bracket 2g7. A perforated link bar 2gg is rotatably mounted on the upper cantilevered end of the support bracket 2g'7. Link par with hole 2g Which upper end is the connecting bar, 2L? It is movably mounted at 0.

A long groove 29/ is formed in the lower end of the holed link par 2gg. A slide pin 29.2 is fixed to the pivot arm 2g3 and retained in the long groove 29/. The end of the connecting bar 270 furthest from the hole linker 2gg is further rotatably attached to a crank arm 273. crank arm, 273
is the Franz 0 block fixed against the shaft g'? It is rotatably attached to 9≠.

When the shaft g3 reciprocates along the arcuate path about its long axis, the crank arm, 293, also moves along the arcuate path. The connecting bar 290 and the holed linker 2gg allow the bushing bar 2gg to pivot up and down in synchronization with other parts of the machine. For example, if a completed foam cylinder/30 is about to be ejected, the 2g fuselage bar is quickly lowered, thereby removing any foam cylinder attached to the end-forming die. . Push bar 2g is then quickly retracted upwards so as to impede further operation of the end guide.

In the operation of the overall apparatus and method of manufacturing containers in this apparatus, foam sheet material is stored on large cylindrical rollers mounted adjacent to the apparatus shown in FIG. are standard and need not be explained for the purposes of this invention. Foam sheet material B! is fed to the device and preheated so that it becomes more flexible and molded to the shape of the mandrel of device 10. The foam sheet material is gripped by gripping mechanism Oj. The gripping mechanism engages the upper edge of the foam sheet material and advances it to a position where the leading edge of the foam sheet material is adjacent the surface of the mandrel 5. At this point, the finger mechanism /33 is in the open position and the fingers /3/ have moved away from the surface of the mandrel 5B. The fingers /3/ are then positioned against the leading edge of the foam sheet material. Then knife lock 97
moves relative to the surface of the foam sheet material and the prenosa foot 102 moves against the surface of the foam sheet material! move relative to the surface of Immediately thereafter the knife 10/ cuts the foam notebook material and the drum is indexed and rotated counterclockwise from top dead center or station/. Immediately thereafter the knife 10/cuts the foam sheet material and the drum moves counterclockwise from top dead center or station/4.
A station displaced in an arc by /-50! It will now be indexed and rotated counterclockwise relative to the position. As the mandrel begins to move along its circular path with the drum, it begins to rotate about its own axis under the action of pinion gear j and stationary gear o. At this point, finger mechanism 733 closes and grips the free end of the cut foam blank material. The mandrel is rotated through a small angle and the roller/ring is moved into position behind the already closed fingers to bring the foam sheet material into close contact with the mandrel surface as the Mantreno L is rotated. The mandrel continues to move along the arcuate path with the drum until it reaches station 2. At this point the mandrel has rotated about its own axis so that the foam sheet material is completely wrapped around the mandrel and the trailing edge of the foam notebook material passes through the hole/g 3 in the mandrel 5. It overlaps the leading edge which is already held in place by the applied vacuum. At this point, the mandrel stops moving along its arcuate path and the surface between the leading and trailing edges of the foam sheet material is heated and softened under the action of hot air introduced from heat distribution nozzle 230. Ru. Once sufficient heat has been transferred to the materials and they become tacky, the sealer assembly, 25!
The tips of are pivoted into position against the overlapping leading and trailing edges of the foam sheet material and pressing them into sealed relationship with each other by using the mandrel surface as a banoquano mandrel. The seal bar assembly, which is stationary and does not rotate with the drum assembly, is then moved away from the surface of the mandrel. The finger mechanism /33 remains in contact with the foam cylinder /30 and thereby prevents this cylinder from changing its position along the axial position of the mandrel JA. When the mandrel is rotated to station 3, no change occurs in its position and the newly formed side seals are cooled and their bond is strengthened. When indexed and rotated relative to the station ≠, the cam track portion 77.2 is actuated thereby causing the ejection collar/l♂ to move slightly along the axial direction of the mandrel 5B. This slight movement of the release collar/II-g causes the foam cylinder/30 to protrude slightly beyond the end of the mandrel feed. The foamed sheet material that projects beyond the end of the mandrel therefore fully receives the heat applied thereto. The mandrel is then moved from the stationer, i.e. top dead station position to /
It is indexed and rotated to a position rotated 10 degrees counterclockwise.

At station 5 and station 5, heat is applied by hot air or radiation to the free foam material projecting beyond the end of mandrel 5. The foam sheet material is oriented so that it contracts circumferentially under the action of applied heat. The foamed sheet material shrinks to a considerable extent and its diameter is significantly reduced. When the mandrel 5 reaches station 7, the bottom forming guide 273 is actuated and moves into position against the end of the softened foam cylinder/30. form a hole or pore;

The guide 273 is then retracted and following this retraction the fingers /3/ are released from their grip on the side walls of the foam cylinder /30 and the release collar /≠ pushes the foam cylinder /30 out of the mandrel 5 where the cylinder The body is an air tube under the action of gravity, l! 77 and is transferred to an assembly or filling line.
