BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice vertical carrying device provided with an endless carrying member guided by a guide sprocket, and more particularly to a guiding structure for the carrying member near the guide sprocket.

[0002]

2. Description of the Related Art Conventionally, in an ice storage attached to an automatic ice making machine or an ice storage independently provided, as a rationalizing means for taking out stored ice cubes, a belt conveyor type, a bucket elevator type Various types of conveying devices such as the ones or the screw feeder type have been proposed and used. However, these transporting devices generally require a slanted transport passage and have a complicated structure, which requires a large installation space. This inevitably resulted in a limited amount of ice storage and a larger ice storage.

In view of these problems, the present applicant has proposed a new ice vertical transport device having a horizontal transport unit embedded in the bottom of the ice storage and a vertical transport unit embedded in the inner surface of the ice storage. (Japanese Patent Application No. 3-44931, etc.) In this ice vertical carrier, a pair of endless chains,
A conveying member is composed of a plurality of horizontal bars installed at a predetermined interval between the chains, and the conveying sprocket is circulated and driven through a horizontal conveying unit and a vertical conveying unit by a driving sprocket arranged above. FIG. 8 shows the installation state of the conveying member 1. The conveying member 1 includes a guide sprocket 2 at the tip of the horizontal conveying portion, a pulley 3 at the tip of the discharging portion, a drive sprocket 4, and a guide rail 5 at the curved portion. 6, 7
And the like, and the driving force is applied by the driving sprocket 4.

[0004]

When carrying an object to be conveyed, that is, ice, using the endless conveying member 1 of this kind, the endless conveying member 1
8, the left side of the portion supporting the transported object, that is, the left side in FIG. 8, is the loose side. With such an arrangement, the driving sprocket 4 causes the conveying member 1 to move.
The tension applied to the roller is considerably small in the horizontal conveyance section far from the drive sprocket 4.

FIG. 9 shows the peripheral condition of the guide sprocket 2 at the tip of the horizontal conveying section. The guide sprocket 2 supported by the shaft 2a is wound around the conveying member 1 consisting of a chain 1a and a horizontal bar 1b. Further, the front end of the horizontal transport unit is surrounded by the front cover 8. The conveying member 1 passes between the upper end of the front plate 10 of the lateral guide plates 9 inside the pair of chains 1 a and the downward edge of the front cover 8. In such a situation, the sagging due to the decrease in tension is prevented by the guide rail 11 on the outer side of the lateral guide plate 9, but the front plate 10 and the guide sprocket 2 that prevent the falling of ice, which is the object to be conveyed, are provided. There is a relatively large space between them, and the transport member 1 is likely to be rolled up as shown by the broken line.

[0006] Such sagging and winding of the conveying member causes phenomena such as interference with other members, generation of noise and vibration, damage and destruction of the apparatus itself, and is not preferable at all. It has been desired to have a structure capable of preventing hang-down and entanglement.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a conveying member guide structure in an ice vertical conveying device in which the circulating conveying member does not sag or wind up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

FIG. 1 shows an ice vertical transport device 12 according to the present invention.
It is a figure showing the whole composition of this, and this ice vertical conveyance device 12
Is a lower horizontal transport unit A, a vertical transport unit B extending vertically (not necessarily at a right angle) upward from the horizontal transport unit A, and a discharge unit C that may be inclined slightly upward. Have. The ice cubes are stacked on the ice vertical transport device 12 in the horizontal transport unit A, carried upward by the vertical transport unit B, and discharged from the ice vertical transport device 12 in the discharging unit C. The horizontal transport section A may be slightly inclined.

The endless chains 1a, 1a which circulate along the above-mentioned respective portions A, B, C are connected by a large number of horizontal bars 1b at predetermined intervals determined in consideration of the shape and size of ice to be conveyed. The transport member 1 including the chain 1a and the horizontal bar 1b is surrounded by a frame 8 which also serves as a cover,
A pulley 13 supported at a proper position of the frame 8, a drive sprocket (not shown) rotated by drive gears 15a and 15b driven by a drive motor 14, a guide sprocket at the tip of a horizontal conveyance unit A described later, It is rotatably supported by appropriate rails, guides 16 and the like. As described above, the drive motor 14 at the upper portion rotates the drive gears 15a and 15b, and the endless transport member 1
However, it circulates the above-mentioned respective parts and conveys the ice from the horizontal conveyance part A which is usually at the bottom of the ice storage to the discharging part C which is located above the ice storage. Inside the chains 1a, 1a, side guide plates 17 are provided facing each other with the horizontal bar 1b sandwiched from both sides.

2 and 3 show the structure of the guide sprocket 2 provided at the tip of the horizontal conveying section A and its vicinity. Sprocket 2 around which chain 1a is wound,
2 is connected by a sprocket shaft 2a, and the coaxial 2a is supported by bearings 2b, 2b at both ends. On the outside of the side guide plate 17, a guide rail 11 is provided below the chain 1a to support the conveying member in the horizontal conveying section A from below and prevent the hanging. From the upper end of the front plate 10 erected at the tip of the guide 16, a support member of the conveying member 1, that is, a horizontal bar guide plate 18 extends obliquely.

In the structure described above, when tension is applied to the conveying member 1 by the drive motor 14, the conveying member 1 moves in the direction of the arrow (see FIG. 3) and the guide sprocket 2 also rotates clockwise. When the tension is small or the chain 1a is loose, the chain 1a and the horizontal bar 1b try to hang downward on the feeding side (the upper right side in the figure) of the guide sprocket 2, but the inclined horizontal bar guide plate 18 However, it smoothly receives the horizontal bar 1b and guides it to the upper right. Thus, the transport member 1 smoothly moves to the right without hanging and transports ice cubes as described above.

Next, referring to FIG. 4, the conditions of the shape and dimensions of the horizontal bar guide plate 18 will be described. The length L of the lateral bar guide plate 18 can be extended to a range that does not hinder the mechanism for the maximum value, and for the minimum value, the range in which the chain 1a is slack when viewed from the side (the upper right quadrant). The outer circumference of the sprocket included in D) is reached and the horizontal bar 1b can be received by the upper surface instead of the tip surface. The inclination angle θ of the horizontal bar guide plate 18 can be changed in the range of 0 ° ≦ θ <90 ° in the direction of the arrow,
Since the maximum value is naturally limited in relation to the length L, it is arbitrarily selected within the range of the inclination angle θ that can satisfy the condition of the minimum value of the length L. However, if the inclination angle θ is too large, the value shown in FIG.
As shown in an exaggerated manner, the bending of the chain 1a becomes large and a heavy load is applied to the drive unit, so caution is required.

The width W between the downward edge portion 8a of the front cover 8 and the root portion 18a of the horizontal bar guide plate 18 should be as small as possible so that each horizontal bar 1b can pass therethrough, and the width W should be as narrow as possible. The shape of the horizontal bar guide plate 18 shown in FIGS. 2 and 3 is of course determined in consideration of the above-mentioned conditions.

FIG. 6 shows a modified embodiment in which the tilt angle θ is approximately 0 °. Therefore, the horizontal bar guide plate 18
Can extend substantially horizontally longer than that of the above-mentioned embodiment, and supports the horizontal bar 1b more smoothly,
You can guide. In addition, as is clear from FIG. 1, there is a curved portion at a portion where the horizontal transport unit A moves to the vertical transport unit B. Figure 7 is an enlarged view showing a side surface of the curved portion by removing the frame 8 from the curved portion, when the pitch of the transverse bar 1b is P, for example, adjacent four horizontal bars 1b ₁ ～1B the distance Q between _4, in the horizontal transfer section a and the vertical transfer portion B, and a Q = 3-Way, when four horizontal bars 1b ₁ ~1b ₄ of adjacent passes the curved portion, Q is gradually Becomes smaller than 3P, reaches the vertical conveyance section B after reaching the minimum value, and Q = 3P again. Therefore, if several ice cubes a are sandwiched in series between the horizontal bars 1b ₁ and 1b ₄ before Q reaches the minimum value, the total length of several ice cubes is constant. On the other hand, since Q decreases toward the minimum value, the chain 1a is locked by the ice cube a and the drive of the chain 1a is stopped. At this time, the maximum tension T acts on the chain 1a and the chain 1a is fully extended, and the lock force F due to the tension T acts on the ice cube a. However, when the power of the drive motor 14 (FIG. 1) is turned off after locking, the maximum tension T and the lock force F are released, so the chain 1a becomes loose and several corners sandwiched between the horizontal bars are released. The lock of the ice a is also released, and the lock phenomenon does not occur even if the ice vertical transport device is restarted. Therefore, a detecting means capable of detecting the lock phenomenon or the drive stop of the chain 1a due to the lock phenomenon is provided, and the drive motor 14 is restarted when the detecting means detects the lock phenomenon. It is preferable to keep it.

[0018]

As described above, according to the present invention, the horizontal conveying portion is located at the tip of the guide sprocket in proximity to the feeding side.
A lateral bar guide plate that is bent and extends from the front plate of the conveying member is provided, and the lateral bar guide plate smoothly supports and guides the lateral bar of the conveying member, so that the guide rail has a complicated shape.
Winding I without endless chain conveying member Taresaga that
The ice vertical transport device can operate smoothly without being jammed.
