Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ice cream serving device that can create a spiral pattern on the circumference of a portion of a conventional soft serve ice cream container. The present invention relates to an ice cream serving device that can serve ice cream in a unique form by applying chocolate or jam to its spiral-patterned surface as needed.

Conventional devices for spirally filling ice cream include a device in which the lower end of a fixed nozzle faces above a rotary cup stand whose rotation speed can be adjusted, as seen in Japanese Utility Model Publication No. 48-11191, and Japanese Utility Model Publication No. 44-20942. As seen in the publication, there is a type that rotates the nozzle, and either the nozzle or the cup stand is raised and lowered in order to serve the soft-serve ice cream from the rim of the container to the outside.

The present invention has a completely different viewpoint from the above-mentioned apparatus, and is designed to be able to heap soft-serve ice cream in a spiral shape from the rim of the container to the outside.

That is, the nozzle for extruding ice cream is made non-rotating, and the nozzle is a rotating body provided with a discharge hole that discharges a portion of the ice cream radially onto the surface of the ice cream discharged from the nozzle mouth end. The nozzle is rotatably mounted on the outer periphery of the nozzle, and the rotating body is configured to be intermittently rotated via a one-way rotation drive mechanism from an air cylinder braked by a hydro check cylinder. Then, on the outer surface of the ice cream extruded from this nozzle, the ice cream diverted from the discharge hole of the rotating body is placed on top so that a spiral pattern is formed only on the outer periphery of the ice cream, and the entire ice cream is spirally shaped. Since the ice cream is not formed into a shape, it is characterized in that the ice cream can be arranged accurately.

Therefore, the driving device for the rotating body is composed of an air cylinder and a hydro check cylinder in which the piston rods are connected to each other by a connecting rod, and the oil inlet and outlet at both ends of the hydro check cylinder are connected by oil pipes to perform the hydro check. The air cylinder is configured so that the hydraulic oil in the cylinder can circulate, and the air cylinder is connected to a pneumatic unit, and a pinion that engages with a longitudinally slidable rack on the connecting rod is interlocked with the driven shaft via a one-way clutch. The driven shaft is configured to be able to drive the driven shaft intermittently in one direction, and further configured to be able to drive the rotating body intermittently in only one direction from the driven shaft via an appropriate transmission mechanism. The whole constitutes a constant speed rotating device, whereby the rotation speed of the rotating body having the auxiliary nozzle is constant,
Therefore, the shape of the ice cream served is constant and a stable product can be obtained.

The embodiments shown in the drawings will be described below.

The present invention is to spirally serve ice cream b in a container a as shown in FIG. A container a is received on a stand 3 and is intermittently conveyed to a nozzle 4 position, and the nozzle 4 is attached to a frame 6 that moves up and down along a guide rod 5 of the machine frame, and the frame 6 moves up and down. It is raised and lowered by the rod 7.

One end of a lever 8 is pivotally attached to the lower end of the lifting lever 7, and the lever 8 swings about a fulcrum 10 of a pedestal 9, and the swinging is performed via a cam 11 and a cam floor 12.

13 is a balancer provided at the other end of the lever 8.

The cam 11 and Geneva gear 1 as described above are driven by a chain wheel 15 and a chain wheel 16 driven by a motor 14 via a continuously variable transmission.
It is driven by a chain wheel 17 which is further driven through the
The cam 11 is operated via a chain wheel 19 stretched between the chain wheel 18 and the chain wheel 17, and the Geneva gear 1 is driven by a pin 22 of an arm 21 of a semicircular plate 20 directly connected to the chain wheel 17.

Note that the drive mechanism is not limited to that shown in the drawings.

The illustrated one includes a tank 23 for supplying jam to the core of the ice cream and a tank 24 for supplying chocolate to the outer periphery of the ice cream.

The ice cream supplied to the nozzle 4 is supplied from a freezer (not shown) through a quantitative supply valve and a pipe 25, and a rotary body rotatably mounted on the outer periphery of the nozzle, which will be described later, is supplied from a constant speed rotation device 26, which will be described later. It is designed to be driven.

Therefore, to explain the structure of the nozzle shown in FIG. 3, the non-rotating nozzle 4 is provided with a through hole 4a in the center in the axial direction for extruding the ice cream b, which is attached to the ice cream filling machine with a lock nut 27. However, the one shown is attached to the nozzle stand 28, and the tank 2 is attached to the nozzle stand 28.
A chamber 28 to which jam is supplied from 3 through a pipe 23a.
A and a chamber 28b into which ice cream is supplied, and jam is supplied from the chamber 28a through a pipe 29 to the center of the nozzle passage hole 4a.

Chocolate is supplied from the tank 24 to the injection head 30 fixed to the nozzle 4 through a pipe 24a, and a rotary body is connected to the nozzle 4 below the injection head 30 through bushes 31 and 32. That is, the rotary cylinder 33 is rotatably driven by the timing pulley 34 of the device.

An auxiliary nozzle 35 is fixed with a cap 36 below the rotating barrel 33 and rotates around the nozzle 4 together with the rotating barrel 33.

The rotating barrel 33 has an annular through hole 33a connecting the pipe 24a and the auxiliary nozzle 35, and a seal 37 and a slip ring 38 are provided to seal between the non-rotating injection head 30 and the rotating barrel 33.

Reference numerals 39 and 40 indicate O-rings interposed between the auxiliary nozzle 35 and the rotating body 33 and between the auxiliary nozzle 35 and the cap 36.

The lower part of the auxiliary nozzle 35 projects downward from the eye end of the nozzle 4, and the mouth end of the auxiliary nozzle 35 has a plurality of discharge holes 41 with a U-shaped cross section that are open at the bottom and communicate with the nozzle 4. The nozzle holes 35a of the auxiliary nozzles are provided in a radial manner and open toward the discharge holes 41.

Therefore, when the timing pulley 34 is driven by a constant speed rotating device 26 (described later) via a belt, the rotating drum 33 rotates along with the auxiliary nozzle 35 at the outer periphery of the eye end of the nozzle 4, and ice cream is extruded from the nozzle 4. Accordingly, a part of the ice cream is extruded from the discharge hole 41 of the auxiliary nozzle 35 while rotating, and chocolate is poured onto the surface of the rotating ice cream from the pipe 24a.
, the through hole 33a, the nozzle hole 35a of the auxiliary nozzle 35, and the discharge hole 41.

As the nozzle gradually rises, ice cream is piled up spirally from the rim of the container as shown in Figure 3.

As described above, a portion of the ice cream is discharged radially from the discharge hole 41 of the rotating auxiliary nozzle 35, so that a spiral pattern is formed on the outer periphery of the ice cream.

Generally, ice cream extruded from a nozzle expands from the end of the nozzle mouth depending on the nature of the ice cream and its discharge pressure, and is extruded into a spit shape. Since the opening is perpendicular to the lower end of the auxiliary nozzle 35 and the lower surface thereof is open, the outer periphery of the ice cream discharged through the nozzle passage hole 4a is suddenly opened at the discharge hole 41 portion. The ice cream flowing through the nozzle passage hole 4a is ejected outward by the horizontal component of the ice cream flowing through the nozzle through hole 4a, and the ice cream in the portion of the auxiliary nozzle where the ejection hole 41 is not provided is also ejected through the ejection hole 41. Since the ice cream tends to flow in the opposite direction, it is subjected to a horizontal force stronger than the horizontal force of the ice cream at the rim of the auxiliary nozzle, which is open on its entire surface, and is ejected quickly and in large quantities through the nozzle passage hole 4a by the rotation of the auxiliary nozzle. It takes on a spiral shape along with the outer surface of the ice cream to be discharged, and is piled onto the outer surface of the ice cream discharged from the five nozzle through holes 4a.

The ice cream passing through the discharge hole 41 is discharged with pressure, so when chocolate is extruded from the nozzle hole 35a of the auxiliary nozzle 35 that opens at right angles to the discharge hole 41, it is guided into the ice cream as described above. The top layer of ice cream is coated onto the surface of the ice cream, which is served in a spiral shape.The top layer of chocolate is applied under pressure, so the chocolate spreads well.

Furthermore, since chocolate or jam is extruded from the center of the nozzle, a core of chocolate or jam is formed at the center of the ice cream.

Next, the constant speed rotation device 2 that drives the timing pulley 34
6 will be explained.

In Figures 4 and 5, 43 is an air cylinder, and 42
is a hydro check cylinder, and these piston rods 42a and 43a are connected to each other by a connecting rod 44, and the one shown is connected by a bolt and nut connection, and the piston rod 43a is connected to a movable base 45 by a bolt and nut connection. connected by bonds.

Further, the air cylinder 43 and the hydro check cylinder 42 described above are arranged horizontally, and they are arranged on the stand of the oar-shaped frame 6a of the frame 6.

The oil inlets and outlets at both left and right ends of the hydro check cylinder 42 are connected to each other by a thin tube 85, and the air cylinder 43
is connected to the pneumatic unit through piping 84.

Furthermore, a rack mounting base 46 is attached to the movable base 45,
This is adapted to move along a track 48 provided on a track mounting bracket 47 on the frame 6.
49 is a sliding body that slides on the track base 48 and is provided on the rack mounting base 46.

Reference numeral 50 denotes a pinion that meshes with the rack 53 of the rack mounting base 46, and is attached to a pinion shaft 51 supported by a bearing 54 on the oar-shaped frame 6a. connected.

Specifically, as shown in FIG. 1, the i movement of the roller clutch 52 = o
A pinion shaft 51 is directly connected to an outer case 55, and a driven inner ring 5 is installed inside the outer case 55 via rollers 57.
A pivot 58 is fitted into the shaft hole 56a of No. 6, and its key groove 56
An inner ring 56 is fixed to a pivot shaft 58 by b and a key.

The outer shape of the inner ring 56 forming a one-way clutch is similar to that of the known one.

The lower part of the collar 58a of the pivot shaft 58 is supported via a bush 61 of a bearing stand 59 attached to the frame 6 and a tapered roller bearing 62, and the upper part of the collar 58a is supported by a bearing nut 63 screwed onto the bush 61. It is supported by a thrust needle bearing 64 that is pressed.

Note that 65 is a thrust needle bearing interposed between the inner ring 56 of the roller clutch 52 and the frame 6.

A pulley 67 is keyed to the lower end of the pivot shaft 58, and the timing pulley 34 described above is driven via the belt 68.

The one shown has five nozzle belts,
Therefore, in order to drive the individual nozzle heads, the gears 72, 73 of the left and right pivots 78, 79 are driven around the gear 69 of the pivot 58 via the intermediate gear 70, 71, and the gears 72, 73 of the left and right pivots 78, 79 are engaged with each other. Gears 76,77 of the pivot 80,81 are driven via mating intermediate gears 74,75, so as to drive pulleys 67 on either side of the pivot.

Note that the intermediate gears 71, 70, 74, and 75 are provided on an intermediate shaft attached to the frame 6 with bolts, and are rotatable via bearings.

Also, as shown in FIG. 6 for the rack mounting base 45.

Its position is adjusted by the slit groove 82 and bolt 83.

Now, when the directional control valve 88 is operated from the state shown in FIG. 8 to connect the pressure air source 87 and the air inlet/outlet 90, the compressed air supplied from the pressure air source 87 is changed to the air shown in FIG. Acting on the piston 43b of the cylinder 43, the piston 43b tries to move rapidly to the left.

However, since the piston rod 42a of the hydro check cylinder 42 is connected to the piston rod 43a by a connecting rod 44, the piston rod 42a is forcibly pulled out as the piston rod 43a moves forward.

At this time, the hydraulic oil in the front chamber of the hydro check cylinder 42 is pressed by the forward movement of the piston 42b, and the small tube 8
A large flow resistance is generated when passing through the piston 42b, and the piston 42b has a large sliding resistance, which prevents the piston 42b from moving forward rapidly.

Therefore, the piston 43b of the air cylinder 43 cannot move forward rapidly, but moves forward slowly.

As the piston 43b moves forward, the rack 53 moves leftward on the track 48, and the pinion 50 meshing with the rack 53 rotates in the direction of the arrow.

The roller-on clutch 52 constitutes a one-way clutch as shown in FIG. 7, and its outer case 55 and inner ring 56 engage only when the pinion 50 rotates in the direction of arrow R. also rotate in the same direction.

When the rank 53 has finished moving forward to a predetermined position, the rack mounting base 46 comes into contact with the limit switch 92 and the control device 89 is activated.
8 is switched, the air inlet/outlet 91 and the pressure air source 87 are now in communication, the piston 43b begins to retreat, and the rack 53 retreats to the right.

At this time, the pinion 50 begins to rotate in reverse, but since the roller clutch 52 does not act, the shaft 58 does not rotate.

Therefore, the rotating body 33 of the nozzle head section also does not rotate.

As the piston 43b retreats, the piston 42b of the hydro check cylinder 42 also retreats, and the hydraulic oil in the rear chamber flows back to the front chamber through the thin tube 85.

When the rack 53 returns to the starting point and the rack mounting base 46 contacts the limit switch 93, the directional switching valve 88 is operated again and the piston 43b of the air cylinder 43 starts moving forward.

As described above, as the piston 43b moves forward and backward, the hydraulic oil in the front and rear chambers of the hydro check cylinder 42 repeatedly circulates.

Note that in order to adjust the rotational speed of the pinion 51, a flow rate regulating valve 85a may be provided in the thin tube 85 as shown in FIG.

Note that 85b indicates an oil cylinder. As described above, a hydro check cylinder is provided parallel to the air cylinder, the piston rod of the air cylinder and the piston rod of the hydro check cylinder are connected so that they move forward and backward at the same time, and the oil inlets and outlets at both ends of the hydro check cylinder are communicated through thin tubes. This allows the hydraulic oil in the hydro check cylinder to circulate, and the air cylinder is connected to the pneumatic unit for operation, resulting in smooth rotation at low speeds without pulsating piston movement. , speed adjustment is also easy.

In addition, since the hydro check cylinder is directly connected with a thin tube, there is no risk of oil leakage, and the amount of hydraulic oil used is extremely small compared to conventional hydraulic equipment, so operating costs are reduced and the effort required for maintenance and inspection is reduced. Become.

In any case, a rotating cylinder 33 that rotates the auxiliary nozzle 35
The timing pulley 34 is a constant speed rotating device as described above.
When the containers come under the nozzle, they are arranged in a spiral pattern, and the timing pulley 34 is always driven in one direction intermittently.

In the embodiment, the auxiliary nozzle is fixed with a cap, but the auxiliary nozzle may be simply a pipe directly connected to the rotary cylinder.

According to the present invention, since the center nozzle does not rotate, the center position of the ice cream to be served is fixed compared to the case where the nozzle is rotated, and the part forming the spiral pattern is formed by the auxiliary nozzle. It is formed when a large amount of ice cream extruded from the nozzle is placed on the outer surface of the ice cream extruded from the center of the nozzle.When chocolate, etc. is extruded toward this nozzle,
Since the ice cream is pushed out while pressure is applied to the ice cream that is being pushed outward, the chocolate sticks well.Moreover, the constant speed rotation device is driven by a rack and pinion, so that it is not auxiliary. The number of revolutions of the rotating body having the nozzle is constant, so the shape of the ice cream served is constant and a stable product can be obtained.

Note that the rotating bodies may be driven simultaneously at the lower limit when the nozzles descend toward the container, or may be driven at different timings.
