Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical transport device for ice, and more particularly, to a vertical transport device for ice that is suitable for transporting ice from an ice maker that produces ice having a relatively uniform shape. It concerns the device.

b. Conventional technology The conventional vertical transport device for ice requires space because the buckets and rake means protrude from the endless belt, and it is difficult to arrange it in a narrow place such as an ice storage of an ice machine. .
Therefore, in order to improve this, the present inventor has proposed that at least two endless belts driven by driving means and a number of horizontal bars bridged between these endless bands at intervals slightly wider than the longest side of ice. And a fixed guide stand arranged on a plane parallel to a plane including these horizontal bars at an interval of about 1/2 to 2/3 between the horizontal bars with respect to these horizontal bars. (See Japanese Utility Model Application No. 1-142040).

The ice discharging portion of such a vertical ice transport device is configured by gradually narrowing the distance between the horizontal bar and the fixed guide portion (see Japanese Patent Application No. 1-142041).

That is, FIGS. 4 and 5 show the ice discharging portions, and the ice 14 carried vertically upward by the horizontal bars 12, 12 of the chains 3, 3 moves between the fixed guide portion 5 and the horizontal bars 12. When the distance is reduced, the center of gravity G is moved to the side without the fixed guide table (see FIG. 5), and the protrusions 5a, 5a adhere to the fixed guide table 5 due to the wetting of the ice surface. When the gap T is formed, a rotating power F is generated on the ice 14, and the ice 14 is dropped and discharged in the direction of the arrow in FIGS.

c. Problems to be Solved by the Invention However, in the proposed vertical conveying device for ice, the supported portion of the ice melts and the ice enters between the fixed guide and the horizontal bar. In the case or when small pieces of ice gather from the beginning and are clogged between the fixed guide bar and the horizontal bar, the ice is crushed with a loud noise at the ice discharge part, so-called There was a problem that ice scum often occurred.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a vertical ice transport device having an ice discharging portion free of ice dust.

d. Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides an endless transport member arranged to be able to circulate and travel freely, and extends in the longitudinal direction of the endless transport member so as to intersect with the traveling direction. A plurality of horizontal bars arranged at a predetermined interval from each other, and a direction discharge unit in a vertical ice transport device including a fixed guide table arranged on a plane parallel to a plane including these horizontal bars, So that the fixed guide is on the upper side and each horizontal bar is on the lower side,
The fixed guide table and the endless transport member are arranged to be inclined in the horizontal direction, and a discharge space is formed between the end of the fixed guide table and a guide for guiding the endless transport member to be inclined in the horizontal direction.

e.Effect At the ice discharge port, the distance between the horizontal bar and the fixed guide is maintained, so there is no ice scumming, and the fixed guide and the endless transport member are arranged inclined in the horizontal direction. However, the center of gravity of the conveyed ice moves along the slope above the horizontal bar and becomes unstable, and after passing the end of the fixed guide, the support becomes only the horizontal bar. The endless transport member falls by its own weight in a discharge space formed between the endless transport member and a guide for guiding the endless transport member in a horizontal direction.

f. Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the vertical ice transport apparatus shown in the drawings.

In the drawings, the same or corresponding portions are denoted by the same reference characters.

In FIG. 1, the vertical transport device for ice comprises a horizontal transport section B, a vertical transport section A, and a discharge section C. Ice is loaded on the horizontal transport section B and discharged at the discharge section C. In this example, the horizontal transport section B is configured integrally with the vertical transport section A. However, the horizontal transport section B may be configured separately from the vertical transport section A. The horizontal transport section B can be replaced with a conventionally known ordinary inclined guide or transport device.

The two horizontal endless belts, which are endless transport members, are made of chains 3, 3 made of stainless steel or synthetic resin, and a large number of horizontal bars 12, 12 are provided between the chains 3, 3 at predetermined regular intervals.・
・ ・ Is mounted. The interval between the horizontal bars 12, 12,... Is determined in consideration of the size of the ice to be conveyed, that is, the ice made by the ice making machine, and is determined by the longest side of the ice (for example, 28 × 28). In the case of × 32 mm, the length is set slightly wider than 32 mm).

In the horizontal transport section B, a large number of horizontal bars 12, 12,...
Below, the interval of about 1/2 to 2/3 of the longest side of the ice to be conveyed, that is, 1/2 to 2/3 of the interval between each horizontal bar 12, 12, ...
At fixed intervals, a fixed guide table 1 is arranged on a plane parallel to the plane including each horizontal bar, and on both sides of the fixed guide table 1, non-water-absorbing materials are provided for guiding the chains 3,3. Guide rails 2, 2 made of a material having self-lubricating properties.

At one end of the chains 3, 3 of the horizontal transport section B, sprockets 6, whose shafts 6a are received by bearings (not shown),
At the other end, guide sprockets 7,7 for the upper chains 3,3 and guide sprockets 9,9 for the lower chains 3,3 are arranged, and The chains 3, 3 are guided from B to the vertical transport section A. In addition,
Sprockets 6,6 and guide sprockets 7,7,9,9 are made of stainless steel or synthetic resin like chains 3,3, and guide sprockets 7,7,9,9 like sprockets 6,6. Shafts 7a, 7a and 9a, 9a are supported by bearings (not shown). The fixed guide portion 1 having the start end 1a at one end of the horizontal transport portion B is an arc which is equal to the outer periphery of the guide sprockets 7, 7 at this portion, without changing the interval between the horizontal bars 12, 12,. , Is bent by about 90 ° to form the lower bent portion 4a, and continues to the vertical fixed guide portion 5 which is vertical. Note that the guide rails 2 also extend to the vertical fixed guide portion 5 through the lower bent portion.

In the vertical transport section A, a large number of horizontal bars 12, 12,...
The vertical fixed guide section 5 at the same interval as the horizontal transport section B in parallel with
Is provided. At the upper ends of the chains 3, 3 of the vertical transport section A, there are arranged guide sprockets 10, 10, 11 and 11, whose shafts are received by bearings (not shown), and driving sprockets 8, 8, The shaft 8a of the sprockets 8, 8 is connected to the motor 13 via a coupling 13a. Drive sprockets 8,8, guide sprockets 10,
The guide sprockets 6, 11 and 11, like the guide sprockets 6, 6, are also made of stainless steel or synthetic resin. In addition, the guide sprockets 10, 10 and 11, 11 can be replaced with normal grooved guide rollers or fixed arcuate guide rails together with the guide sprockets 7, 7, 9 and 9, especially, with the fixed arcuate guide rail. In this case, the mounting space can be significantly reduced.

As shown in FIG. 2, the discharge space of the ice discharge part C is:
It can be formed by the positional relationship between the guide sprockets 10, 10 and 11, 11, which are guides for guiding the chains 3, 3, which are endless transport members, and the end 5a of the fixed guide table 5. That is, the relationship between the fixed guide table 5 and the chains 3, 3, which were vertical and parallel at a distance L in the vertical transport section A, was changed to the upper position without changing the distance L between the two. The fixed guide table 5 and the endless transport member (guide sprockets 10, 10 and 11,
11) are arranged horizontally inclined, and an ice discharge space is formed between the terminal end 5a of the upper bent portion 4b of the fixed guide table 5 and the guide sprockets 11, 11 serving as guides of the endless transport member. .

Reference numeral 15 denotes a front cover, and a tip 15a of the front cover protrudes from the end 5a of the fixed guide portion 5 in the advancing direction, supports the conveyed ice 14 by that amount, and can control the ice discharge position.

Now, the normal ice 14 is fixed guide 5 and the horizontal bar 1 of the chain 3,3
When both are supported and pushed up by 2 and reach the ice discharging portion C, the fixed guide portions 5 are arranged in a horizontal direction so that the horizontal bars 12, 12 are on the lower side, so that the fixed guide portions 5 are on the upper side. ice
14 is no longer supported by the fixed guide portion 5, and slides down the horizontal bar 12 due to its own weight and falls. When the front cover 15 is provided as a guide at a position for supporting the falling ice 14, the ice 14 is supported by the end 15a of the front cover 15, and is fed horizontally by the horizontal bar 12. , Its end
Drops and is released at 15a.

The supported part of the ice 14 melts and the ice 14 is fixed
2 (see FIG. 2), the distance between the fixed guide table 5 and the horizontal bar 12 at the ice discharge section C is not reduced, and the fixed guide section 5 is positioned above the ice 14. Because
The support of the ice is transferred to the horizontal bar 12, and after the end 5a of the fixed guide table 5, the ice 14 is supported only by the horizontal bar 12 and becomes extremely unstable. The ice 14 usually falls clockwise and drops depending on the position of the center of gravity, but the front cover 15

If it is clogged between the horizontal guide bar 12 and the
The small piece of ice that has fallen due to the inclination of
It will be released by being pushed by the normal ice sent from behind.

Therefore, such an ice discharging portion C is provided with the fixed guide portion 5.
The ice can be discharged reliably and quietly (because the ice is not broken) without causing the phenomenon of ice skewing between the ice and the horizontal bars 12,12.

Further, a discharge space is formed between the end 5a of the fixed guide table 5 and the guide sprockets 11, 11 serving as guides for the endless transport member, and when the guide deflects the endless transport member, the discharge space is located inside the endless transport member. Is compressed and the outside expands, so that as shown in FIG.
If 4 '(melted or broken) enters and becomes clogged, ice 14, 14, and 14' will be released outside in the discharge space in front of these guide sprockets 11, 11 to clear the clog. You.

g. Effect of the Invention According to the present invention, since the distance between the fixed guide table and the horizontal bar does not change at the ice discharge part of the vertical ice transport device, the phenomenon of ice scum at the ice discharge part does not occur, and Ice can be released quietly. Also, ice clogged between the horizontal bars is discharged from between the horizontal bars when the endless transport member is deflected by a guide for tilting and guiding the endless transport member in a horizontal direction so as to form an ice discharge space. Is done.
