Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical conveying device for ice in an ice making machine, and more particularly to a vertical conveying device suitable for conveying ice in a closed cell type ice making machine for making ice of a relatively uniform shape. is there.

[0002]

2. Description of the Related Art In a conventional automatic ice making machine, a front door for taking out ice is provided at the front of the ice storage, and the front door is opened to take out the ice from the ice storage. The take-out work is done using a scoop, and the work was a heavy burden when the position of the front door was low.

By the way, in the ice storage, since it is necessary to operate the ice storage detection switch, a sufficient space is provided in the upper portion and the inner portion. In order to use this space and the space on the top plate, the upper portion of the ice storage is used. There has been an attempt to install an auxiliary refrigerator in the upper part of the ice storage in order to reduce the burden of the work of taking out ice from the front door. There is.

It has also been proposed to provide a vertical carrier for ice in the ice storage and take out the ice from the ice storage through an outlet at the top of the ice storage (Japanese Utility Model Publication No. 48-77742). This vertical ice carrier has a large number of buckets mounted between two endless belts.

Various vertical ice conveying devices are used in addition to the ice making machine. For example, a screw type conveying device (Japanese Utility Model Laid-Open No. Sho 56-130675) and two endless belts with a large number of rake means are used. Ice-breaking supply device equipped with (Japanese Patent Publication Sho-60-11792
Issue gazette).

[0006]

In the conventional ice vertical conveying apparatus, particularly, the bucket and the rake means attached to the endless belt, the bucket and the rake means project from the endless belt to the surroundings, and the space corresponding to that is provided. Is not only difficult to place in a narrow space such as the ice storage of an ice making machine, but also the amount of transportation differs depending on the amount of ice storage,
There is a problem that crushed ice is also conveyed indiscriminately. In addition, screw type conveyors not only crush the ice by biting the ice between the screw shaft and the cylinder that wraps the shaft, but also There was a problem that the device was damaged.

The present invention has been made in order to solve the problem of the vertical ice conveying device in the conventional ice making machine, and can be easily arranged in a narrow space of the ice making machine, and the ice storage amount can be increased. It is an object of the present invention to provide a vertical carrier device for ice in an ice-making machine, which carries a fixed amount of water regardless of the number of items, and selects and carries only ice having a relatively constant shape.

[0008]

In order to achieve the above-mentioned object, the present invention is a vertical conveying device for ice in an ice making machine provided with a vertical conveying portion continuously connected to a horizontal conveying portion, driven by a driving means. At least two endless belts, a large number of horizontal bars mounted between the endless belts at intervals slightly wider than the longest side of the ice making, and in a space surrounded by these horizontal bars. The horizontal guide bars are fixed to the horizontal bars at intervals of about 1/2 to 2/3 between the horizontal bars.

Further, when the vertical ice transporting device is attached to an ice storage having a front door, a control means is provided to control the endless belt drive means so that it does not operate when the front door is open. is there.

[0010]

The ice contained in the horizontal carrying section of the carrying device enters the space formed by the two endless bands, the front and rear horizontal bars and the fixed guide table, and the It is pushed up by each horizontal bar by turning. However, those that do not enter the space, that is, those that are merely placed on the horizontal transport unit, are not transported by the vertical transport unit. In addition, small pieces of crushed ice, etc., have few supporting portions, and fall in the vertical conveying unit due to endless vibration and reaction of inertia in the bent portion from the horizontal conveying unit to the vertical conveying unit. Therefore, the transported ice does not exceed the amount stored in the space,
At the same time, the shape and size of the ice carried is substantially uniform.

When this ice vertical transport device is mounted on an ice storage box having a front door, the control means controls the drive means of the transport device so as not to operate when the door is open.

Embodiments of the present invention will be described below with respect to a vertical ice transporting device in an ice making machine shown in the drawings. In addition,
The same or corresponding parts are designated by the same reference numerals. Figure 1
In Fig. 1, the vertical ice transport device includes a horizontal transport unit B, a vertical transport unit A continuously connected to the horizontal transport unit B, and a discharge unit C provided in the vertical transport unit A. Is automatically loaded in the horizontal transport section B, is carried upward in the vertical transport section A, and is discharged in the discharge section C.

The two parallel endless bands consist of chains 3 and 3 made of stainless steel or synthetic resin. Between these chains 3 and 3, a large number of horizontal bars 12, 12 ...
Is mounted. The mutual distance between the horizontal bars 12, 12 ... Is determined in consideration of the size of ice to be conveyed, that is, ice to be produced by an ice making machine, and the longest side of the ice to be produced (for example, 28). 32m for x 28 x 32mm
The distance is set to be slightly wider than the length of m).

In the space surrounded by a large number of horizontal bars 12, 12, ... Mounted between the two endless belts of the horizontal conveying section B,
A horizontal fixed guide 1 with a horizontal bar 12 above it,
12 ... is about 1/2 to 2/3 of the longest side of the ice, that is, about 1/2 of the interval between the horizontal bars 12, 12.
It is placed with a spacing of 2/3. Guide rails 2 and 2 having a non-water-absorbing property and self-lubricating property are mounted on both sides of the horizontal fixed guide 1 to guide the chains 3 and 3 (see FIG. 2). .

At one end of the chains 3 and 3 of the horizontal transport section B, sprockets 6 and 6 which receive a shaft 6a thereof by a bearing (not shown) are arranged to guide the chains 3 and 3. The sprockets 6 and 6 are chains 3 and 3.
Made of stainless steel or synthetic resin as well.

At the other end of the chains 3,3 of the horizontal transport section B, guide sprockets 7,7 for the upper chains 3,3 and guides for the lower chains 3,3 are provided. Sprockets 9, 9 are arranged to guide the chains 3, 3 from the horizontal transport section B to the vertical transport section A.
The guide sprockets 7, 7 and 9, 9 are also made of stainless steel or synthetic resin like the sprockets 6, 6, and their shafts 7a, 7a and 9a, 9a are supported by bearings (not shown). Instead of these guide sprockets 7, 7 and 9, 9, a normal grooved guide roller may be used.

The fixed guide base 1 in this portion is bent 90 ° along an arc equal to the outer circumference of the guide sprockets 7 to form a bent portion 4, and continues to a vertical vertical fixed guide base 5 in the vertical transport unit A. ing. The guide rails 2 and 2 on both sides of the fixed guide 1 also extend to the vertical fixed guide 5 via the bent portion 4.

At the ends of the chains 3 and 3 of the vertical transport section A,
Drive sprockets 8 and 8 for the chains 3 and 3 are arranged,
The shaft 8a is connected to the motor 11 via the coupling 10. Like the other sprockets, the driving sprockets 8 and 8 are also made of stainless steel or synthetic resin, and their shafts 8a are supported by bearings (not shown).

In FIG. 2, reference numeral 16 is an attachment for attaching the horizontal bar 12 to the chain 3, and 17 is an attachment for attaching the guide rails 2 and 2 to the fixed guide portion. Reference numeral 18 is a cover for the device made of stainless steel or synthetic resin.

The ice discharging section C is provided in the vertical transport section,
The vertical fixed guide 5 is arranged so as to be inclined with respect to the upper lateral bars 12, 12 ...

As shown in FIG. 4, an ice guide 19 having an ice discharge port 20 is provided at the ice discharge section C in the vertical transport section A.
It is preferable that the ice discharge port 20 is provided in the front of the vertical fixed guide base 5 and the space between the horizontal fixed bar 5 and the horizontal bars 12 is almost eliminated.

FIG. 5 shows an ice making machine R with an ice storage having a front door 22 to which a vertical conveying device for ice in the ice making machine according to the present invention is attached. In the drawing, 21 is a top plate of the ice making machine. Yes, 23 is a drive switch of the vertical transport device.

This vertical transporting device for ice is arranged so that the horizontal transporting part B is located at the place where the ice just made falls in the ice storage, and the vertical transporting part is located at the back of the widest blank space. It is attached so that A is located.
Further, the ice discharge port 20 is provided so as to be located just above the top plate 21. Therefore, the ice can be taken out to a high position on the top plate 21 without significantly reducing the amount of ice stored in the ice storage.

Now, when the drive switch 23 of this vertical ice carrier is turned on, the motor 11 is rotated, the drive sprocket shaft 8a is rotated in the direction of the arrow, and the drive sprockets 8 and 8 cause the chains 3 and 3 to move in the arrow direction. In the horizontal conveyance section B, the ice contained in the space S (the hatched portion in FIG. 1) surrounded by the adjacent horizontal bars 12, 12 and the parallel chains 3, 3 and the horizontal fixed guide 1 in the horizontal conveyance section B ( Ice 13)
Are pushed by the lateral bars 12, 12 ... With the rotation of the chains 3, 3 and proceed to the vertical transporting section A through the bending section 4 of the horizontal fixed guide 1, as shown in FIGS. 1 and 3. So that
The ice 14 is carried in the direction of the arrow, that is, upward while being supported by the horizontal bar 12 and the vertical fixed guide 5 (or supported by the subsequent ice).

Even if the ice that has been loaded in the horizontal transport section B and has not been successfully put into the space S is pushed by the ice contained in the space S to proceed, it is supported by the horizontal bar 12. Since it does not exist, it is not carried upward in the vertical transport section A. Therefore, the amount of ice carried up by this vertical ice carrier is
Only the amount of ice that exactly entered the space can be captured relatively easily by the operating time of the device. It should be noted that the ice that has been crushed into small pieces enters into the space leaving a lot of gaps and is unstable, so that in the vertical transport unit A, vibrations of the chains 3 and 3 are caused.
Many of the bent parts 4 fall off from the vertical transport part A due to a reaction due to inertia when abruptly changing the movement direction, and few of them are correctly discharged from the ice discharge port 20. Therefore, this vertical transporting device can sort the ice to be transported.

The ice is discharged in the discharging portion C.
As shown in FIG. 4, the horizontal bar 12 (and subsequent ice 1
5) The ice 15 supported in 5) is guided by the inclination of the vertical fixed guide 5, and the inclination gradually narrows the distance between the vertical fixed guide 5 and the horizontal bar 12 toward the discharge portion C. Therefore, the center of gravity of the ice 15 comes off the support of the horizontal bar 12, and the ice 15 is stronger than the adhesive force of the ice 15 to the fixed guide 5.
When the gravity in the direction of gravity wins, the ice falls and the discharge port 20
Released more. As shown in FIG. 4, when the ice guide 19 is provided, the ice can be reliably discharged at a fixed position. The ice guide 19 and the discharge port 20 are also made of stainless steel or synthetic resin. The tension adjustment of the chains 3 and 3 is performed by moving the drive sprocket shaft 8a together with the coupling 10 and the motor 11.

In such a vertical ice transporting device, the front-back width of the transporting device corresponds approximately to the diameter of the sprocket, and two endless belts (three or more, if necessary, are provided between the respective endless belts). The horizontal bar can be laid horizontally.) Since it only occupies the space of the width, and even in a narrow place such as the ice storage of the ice making machine R, it can be installed by selecting an effective place for space use. For example, the amount of ice stored in the ice storage is not reduced, and only a certain amount of ice that has entered the space S is carried regardless of the amount of ice storage, so it is easy to control the drive speed and time. The conveyance amount can be controlled, and further, the ice that does not fit into the space S cannot be carried up, so that the conveyance ice can be sorted.

FIGS. 6, 7 and 8A and 8B show a control for safety measures when the vertical ice transporting device according to the present invention is attached to an ice storage having a conventional front door. Means are shown. FIG. 6 shows a switch 24 attached to the body of the ice making machine R (ice storage), and this switch 24 constitutes a simple control means of the drive means of the vertical ice carrier. That is, the switch 24 is closed when the front door 22 is closed and the switch pin 24a is pushed, and is opened when the front door 22 is opened. The switch 24 is incorporated in the drive switch circuit of the drive means in series to drive the drive means. Is to control. The switch pin 24a
It is preferable to take drip-proof measures.

In the example of FIG. 7, a spring 22c is stretched between a bracket 22a provided on the front door 22 and the main body R,
A switch plate 22b is attached to the bracket 22a or the spring 22c. As with the example of FIG. 6, when the front door 22 is closed, the switch 24 is closed and the front door 2
When the switch 2 is opened, the switch 24 is opened, and constitutes a control means for controlling the drive means.

The example shown in FIGS. 8A and 8B is shown in FIG.
The switch 24 is replaced with a reed switch 26, and 25 is a magnet attached to the bracket 22a. Reed switch 2 according to opening / closing of front door 22
The contact of 6 opens and closes, this signal is input to the control circuit of the control means, and the drive means is controlled by a command from the control means.

As described above, since the control means for the driving means of the ice vertical transporting device is provided, the drive means of the vertical transporting device does not operate even if the drive switch is pressed when the front door is open, and the work is performed. People do not get their hands caught in the chain, side bar, sprocket, etc. of the vertical transport device when trying to remove ice from the front door.

[0032]

According to the present invention, since there is no bucket or rake means extending outwardly from the endless belt as in the conventional carrier device, the space occupied by the carrier device can be reduced accordingly, and the ice making machine can be used. It can be installed in a small place such as an ice storage, and the amount of transported ice and the shape and size of ice to be transported can be made relatively constant.

If the drive means is provided with a control means that does not operate when the front door is open, the operator can remove the ice from the front door when applied to an ice making machine with an ice storage container having a conventional front door. As a vertical conveyor chain, horizontal bar,
Do not get injured by being caught in a driven part such as a sprocket.
