DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a cheese storage device for a cheese stocker for storing cheese in a cheese stocker that temporarily stores rolled up cheese in a winder factory or the like.

Prior Art In winder factories, etc., it is necessary to temporarily store rolled cheese (regardless of whether it is corn cheese or parallel cheese, the same applies hereinafter) before transporting it to the next process. For this purpose, a multi-stage cheese stocker has been proposed in which a transverse belt is provided for each stage and cheese is stored in a line on this belt (for example, Japanese Patent Application Laid-Open No. 193868/1983).

In order to store cheese in this type of cheese stocker, it has conventionally been done to make each cheese stocker tier movable up and down to adjust the height between the cheese storage device and each tier. Then, it is necessary to either move all the tiers in parallel while maintaining the interval between the tiers to accommodate the cheese in each tier, or to lower the tier while reducing the tier interval after all the cheese in each tier has been carried out. In the former case, the total height of the cheese stocker becomes excessive due to the long vertical movement distance, and in the latter case, the upper tier cannot be lowered if even one cheese remains on the middle tier, so the cheese stocker is This was accompanied by a practical difficulty in that storage could only be done in order starting from the top shelf.

Purpose of the Invention In view of the problems of the prior art, it is an object of the present invention to provide an elevator for conveying cheese that runs in the vertical direction so that the cheese stocking stage of the cheese stocker does not have to move in the vertical direction, but the cheese can be placed on a predetermined stage. By making it possible to store
To provide a device for storing cheese in a cheese stocker, which allows cheese to be stored in any stage at any time even though the total height of the cheese stocker is set appropriately.

Structure of the Invention The structure of the present invention to achieve the above object includes a transfer device equipped with a swinging fork in front of a conveyance elevator that conveys cheese in the vertical direction, and a transfer device equipped with a swinging fork at each stage of a cheese stocker after the conveyance elevator. A rotatable shutter is provided for controlling the storage of cheese in the cheese stocker, and by tilting the swinging fork, the cheese placed on it is moved onto the receiving plate of the conveyance elevator. The gist thereof is to be able to control selective storage of cheese from a conveyance elevator to a predetermined stage by rotating the shutter of any stage of the cheese stocker.

The upper part of the slide plate 12 protrudes above the frame 11, and a swing plate 13 is pivotally connected via a shaft 19 (FIGS. 4 and 5). Rotation of the swing plate 13 about the axis 19 is smooth due to the bearing 19a. The singing plate 13 has two fork pieces 14a, 14a.
protrude horizontally and in parallel to form a swinging fork 14. The interval between the fork pieces 14a, 14a is made smaller than the minimum diameter of the cheese 2, and the cheese 2 can be stably placed on this interval.

A tongue piece 20 is provided upright at the lower end of the swing plate 13 and engages with a pin 20a on the slide plate 12, and a coil spring 21 is installed between the spring pin 21a on the swing plate 13 and the frame 11.
has been set up. The coil spring 21 biases the swing plate 13 counterclockwise in FIG. 4, and the pin 20a resists this bias and holds the swing plate 13 vertically. Further, the frame 11 is provided with an adjustment bolt 22 against which the tongue piece 20 comes into contact when the slide plate 12 moves forward.

The conveyance elevator 30 vertically spans the chain 31 via chain sprockets 31a and 31b provided at a position higher than the top level and lower than the bottom level of the cheese stocker 1 (FIG. 1),
On this, receiving plates 32, 32 on which cheese 2 can be placed
... has been added. The chain sprocket 31a can be rotated by a motor 33 in the direction of arrow A in the figure. Here, the chain 31 is
The upper and lower chains are stretched in parallel, and the receiving plate 32 is a substantially L-shaped plate commonly attached between the two chains 31, 31 (Fig. 4, 7), its base 32b is the cheese 2
Two receiving plates 32, 3 that form an acute angle close to a right angle with the supporting surface 32a on which the
2 forms a basket for conveying the cheese 2. Further, a plurality of crosspiece plates 33, 33, . . . are attached to a portion forming the back wall surface of this basket. The support surface 32a of the receiving plate 32 has a support surface 32a in the opposite direction from the base 32b, that is, a shutter 5, which will be described later.
A notch 32c opening in the direction 1 is provided (FIG. 7).

A shutter 51 is provided on the descending side of the transport elevator 30, protruding into the notch 32c of the receiving plate 32, and capable of rotating between a position intersecting the receiving plate 32 and a substantially vertical position. Figures 7 and 8
figure). The shutter 51 is placed along the descending chains 31, 31 at a height position corresponding to each stage 1a, 1a, . . . for storing cheese of the cheese stocker 1.
a, 1a, .
c and a bracket 52d.

The bracket 52d that fixes the shutter 51 is
It protrudes on the cheese stocker 1 side, and the shutter 5
1 intersects with the receiving plate 32, this bracket 52d connects the shutter 51 and the cheese stocker 1.
(FIG. 8), the upper surfaces of the shutter 51 and the swash plate 53 form a substantially integrated slope. It forms a slope, the lower end of which is located closest to the side end of the transverse belt 1b. Swash plate 53
The notch 53a and the notch 32c of the receiving plate 32 face each other, and the shutter 51 substantially rotates within the vertical plane about the shaft 52b within both the notches 53a and 32c.

Below the upper side of the transverse belt 1b, a supporting plate 1c with a wide V-shaped concave center part is laid, and a supporting plate 1c is installed at the rear of the inclined slope (in the direction opposite to the traveling direction of the transverse belt 1b indicated by arrow c in FIG. 7). direction), an attitude control plate 1d is provided across the transverse belt 1b.

When the cheese 2 to be stored is placed on the swinging fork 14 (FIG. 4), the air cylinder 18 is operated via a control circuit (not shown), and the slide plate 12 is slid forward to the right in the figure. While the slide plate 12 is moving forward, the adjustment bolt 2
2 comes into contact with the tongue piece 20 erected at the lower end of the swing plate 13, so the swing plate 13
is tilted clockwise about the shaft 19 against the tension of the coil spring 21 (double-dashed line in FIG. 4). Therefore, the swinging fork 14 also tilts,
The cheese 2 placed thereon rolls onto the receiving plate 32 of the conveyance elevator 30 that moves upward in the direction of arrow B in the figure, is held there, and is transferred to the chains 31, 31.
transported upwards by the two receiving plates 32,
The innermost part of the basket formed by 32 is the crosspiece 3
Since the chains 3, 33, .

Here, it is assumed that a detector (not shown) sends a signal to the control circuit so that the operation timing of the air cylinder 18 is synchronized with the traveling timing of the basket formed by the receiving plates 32, 32.

After the cheese 2 is transferred to the conveyance elevator 30 by tilting the swinging fork 14, the air cylinder 1
8, the slide plate 12 is returned to its original position. At this time, as the slide plate 12 returns, the swing plate 13 is pulled back in the vertical direction by the coil spring 21, and the tongue piece 20 completely returns to the vertical position at the position where it contacts the pin 20a, and the tongue piece 20 and the head of the adjustment bolt 22 are separated.

If the height of the adjustment bolt 22 is increased, the swing plate 13 will begin to tilt at a small stage in the forward movement of the slide plate 12, so the maximum tilt angle will be large; if the height is decreased, the opposite will be true. Thus, the movement of the swinging fork 14 can be adjusted.

When the basket containing the cheese 2 rotates around the upper chain sprocket 31a, which is the top dead center of the conveyance elevator 30, and moves to the downward stroke, the top and bottom of the receiving plate 32a that supports the cheese 2 is reversed, but the cheese 2 is still remains in the basket. As long as the shutters 51, 51... provided at the positions corresponding to the respective stages 1a, 1a... of the cheese stocker 1 stand in substantially vertical positions (double-dashed lines in FIG. 8), the transport elevator 30 and Since each stage 1a, 1a... is partitioned by a shutter 51, the cheese 2 is
Continue descending along the cheese stocker 1 (arrow D in the figure).

Before the receiving plate 32 supporting the cheese 2 passes, the shutter 51 corresponding to the stage 1a on which the cheese 2 that has been conveyed is to be stored.
(solid line in Figure 8).
As the receiving plate 32 moves downward while crossing the shutter 51, the shutter 51 passes through the notch 32c of the receiving plate 32 and rises upward, so the cheese 2 is placed on the upper surface of the shutter 51. As a result of being scooped up and prevented from descending, the receiving plate 3
2 comes to be supported on the upper surface of the shutter 51 and begins to roll down on the inclined slope formed by the shutter 51 and the swash plate 53.

Therefore, if the air cylinder 52 is immediately operated to rotate the shutter 51 to a substantially vertical position, the cheese 2 will pass through the lower end of the swash plate 53 and reach the predetermined step 1a.
The vehicle falls onto the traveling belt 1b and is stored there. Here, the posture control board 1b contacts the bottom periphery of the cheese 2, etc., so that the axis of the cheese 2 is correctly aligned with the transverse belt 1.
The support plate 1c under the transverse belt 1b supports the weight of the stored cheese 2 and supports the movement of the cheese 2 in the same direction as the moving direction of the cheese 2 (arrow C in FIG. 7). Wide V in the center
Since it forms the shape, it helps to ensure the stability of the cheese 2. In order to prevent the cheese 2, which is forcibly transferred onto the traversing belt 1b by the rotation of the shutter 51, from crossing the traversing belt 1b too far, the cheese 2 is placed on the opposite side of the shutter 51 that narrows the traversing belt 1b. A contact member is provided.

When the cheese 2 is transferred and stored on the transverse belt 1b, this is detected by a detector (not shown), and the transverse belt 1b is advanced by a predetermined pitch in the direction of arrow C, in preparation for storing the next cheese.

The shutter 51 is connected to each stage 1 of the cheese stocker 1.
a, 1a..., and each can be rotated independently, so that the cheese 2 conveyed by the conveyance elevator 30 can be moved to any stage 1.
It is possible to store them in a random order. Therefore, even if cheeses 2 of different brands are mixed and transported in random order by the overhead traveling type conveyance device 3, when removing the cheese 2 from the rack 3b, the brand is read by the detector and the cheese is 2
The progress of the cheese stocker 1 in the transfer device 10 and the transport elevator 30 is stored in a register, and this signal is used to control the shutter 51 corresponding to each stage 1a of the cheese stocker 1. It is also possible to sort and store cheese 2 by brand in each stage 1a, 1a, . . . .

Effects of the Invention As explained above, according to the present invention, a transfer device, a conveyance elevator that travels in the vertical direction, and a rotatable shutter that partitions the conveyance elevator and each stage of the cheese stocker are provided, and a transfer device is provided. The cheese placed on the swinging fork for cheese placement of the device is stored in the basket of the conveyance elevator and conveyed upward, and when it descends along the cheese storage steps layered in the cheese stocker, a predetermined Scooping up the cheese in the basket by protruding a shutter at a position corresponding to the tier to a position intersecting the receiving plate forming the basket, and causing the cheese to fall onto a transverse belt of a predetermined tier and be stored therein. Since the shutters are located at positions corresponding to each stage and can be independently controlled in rotation, cheese can be moved to all predetermined stages in any order without having to move each stage vertically. Moreover, since there is no need to move each stage up and down, there is no need to make the total height of the cheese stocker too large, which is an excellent practical effect.

In addition, even when a mixture of different brands of cheese is transported by an overhead conveyor, the brand information is read when the cheese is taken off the hook of the transport device, and this information is transferred to the transfer device and the conveyor. By storing information in a register corresponding to the cheese being conveyed via the elevator, and controlling the rotation of the corresponding shutter when the cheese moves down a predetermined stage position, Since cheese can be stored in a specific tier, there is also the excellent effect that it is possible to selectively store cheese by brand.
