Description

[Detailed Description of the Invention] The present invention relates to a sake lees peeling device that peels off sake lees adhering to the surface of either a filter plate or a pressing plate in a sake brewing press.

Conventionally, as a sake brewing machine, filter plates and pressing plates, each with a filter cloth wrapped around both sides, are stacked alternately and pressed together in a row in the left and right direction using a pressurizing device, and air pressure is injected into the pressing plates. The moromi placed between each filter cloth is pressed, and after depressurization, each filter plate and pressing plate are sequentially opened from one side and the sake lees is peeled off from each small section using a spatula. required a great deal of effort.

The work after separating the filter plates mentioned above is all manual work, and since the sake lees is a valuable product, it must be removed without losing its shape, but it not only requires special techniques but also can be done within a short period of time. Workers were extremely fatigued because they had to complete the work. In addition,
In recent years, the number of people skilled in the above-mentioned lees peeling work has been decreasing, so there is an urgent need to automate the lees peeling work.

In view of the above circumstances, the inventors of this invention previously filed a patent application in 1983.
-119220, we announced a device that has a separating device, a peeling device, a lees receiving device, and an unloading device to perform a series of automation.

By the way, the peeling device in the above-mentioned application is designed to remove the scraper between the filter cloth and the lees by moving the scraper forward without swinging the tip of the thin scraper in contact with the filter cloth surface of the pressing plate or filter plate. The tip is bent as if pushed in. However, the lees that adhere to the pressing plate and filter plate after squeezing are generally quite hard, and the edges of the lees are sloping to some extent, so it is difficult to simply move the scraper forward as described above. In some cases, the tip of the scraper rides on the slope of the lees and cannot penetrate the lees, and the lees does not always have uniform hardness and adhesive strength, so the tip of the scraper rides on the slope of the lees and may not be able to dig into the lees. Or, it may climb over parts of the lees that have strong adhesion. Therefore, it can be said that how reliably the tip of the scraper bites into the edge of the lees and how the scraper moves forward determines the quality of the lees peeling.

In the present invention, a traveling pedestal is provided on the upper part of the mortar press so as to be movable in the left-right direction, and a supporting member is suspended from a protrusion on at least one side of the pedestal so as to be movable in the front-back direction.
The support member includes a reciprocating member that can move forward and backward with respect to the separated single compression plate or filter plate, a vertically elongated scraper holding member that is fitted to the tip of the retractable member so as to be able to move up and down, and the holding member. A peeling device is provided which consists of a plurality of thin blade-like scrapers arranged in a multi-tiered manner and each of which has a thin blade at the tip, each of which is attached so as to be able to swing from side to side.The peeling device is configured to rotate the tip of the blade into a compressing plate or a filter plate by swinging each scraper from side to side. From the state of contact, the scraper is vibrated up and down by vertical reciprocation of the holding member and moved forward along the filter cloth surface on the plate, so that the tip blade part bites between the filter cloth and the dregs. It is an object of the present invention to provide a lees peeling device for a sake brewing mortar press, which is characterized in that the lees are removed as the process progresses, and whose purpose is to completely peel off the lees without leaving any residue.

The wire rope 36, the pulley 37, and the actuating cylinder 38 are fixed to the intermediate portion of each of the reciprocating members and are attached at their other ends to the ends of the rods extending upward.
Thus, each scraper holding member 33a, 33b,
By repeating the rod extension and retraction action of the actuating cylinder 38, each scraper holding member 33a, 33b is moved up and down.
By vertically moving the scrapers 3b, 33'a, and 33'b, the scrapers are vertically vibrated.

Next, the effect will be explained. After pressing the mash, a pair of filter plates 4 and pressing plates 5 are separated using a separation device (not shown), and only the filter plate 4 is moved to the right end. The pressing plate 5 is held in the upper space of the frame-shaped frames 1a and 1b with the lees adhered to it as shown in FIG.

Driven by the prime mover 13, the traveling frame 7 moves to a position corresponding to the pressing plate 5, and then each scraper 34a ₁ -a ₈ , 34b ₁ -b ₈ , 34'a ₁ -a ₈ , 3
_4'b1 to _b8 remain in the open state and are slightly moved toward the center by the drive of the prime mover 17 via the supporting members 23, 23'. Therefore, each scraper is in a position where its leading edge portion faces the frame member 5c of the pressing plate 5. Next, each scraper is closed by the extension operation of each small cylinder 35, and the frame material 5c is clamped by the tip blade portion (FIGS. 4, 5, and 6).

Subsequently, by actuation of the cylinders 27a, 27b, the reciprocating members 28a, 28b both start moving forward toward the center, and at the same time, the two front actuating cylinders 38 start reciprocating the rod.
Due to the operation of the cylinders 27'a, 27'b with a slight delay, the advancing/retracting members 28'a, 28'b also start moving forward toward the center, and at the same time, the two rear operating cylinders 38 are also moved to the rod. Starts the reciprocating movement of expansion and contraction.

Therefore, the advancing/retracting members 28a, 28b, 2
By the forward movement of 8'a and 28'b and the reciprocating movement of the rod extension and contraction of the operating cylinder 38, each scraper 34a ₁ -a ₈ , 34b ₁ -b ₈ , 34'a ₁ -a ₈ , 34'a ₁
~b ₈ moves forward along the 3 surfaces of the filter cloth while moving up and down, so the tip blade of each scraper vibrates up and down to remove the dregs P.
It bites between the edge of the filter cloth 3 and the filter cloth 3, and transmits the vibration to the lees P, forcibly peeling off even the hard lees P.

The extension of the cylinders 27a and 27b ends at a position where the tip end portions of the scrapers 34a ₁ to _{a 8} and 34b' ₁ to b ₈ are slightly inserted from the center line of the pressing plate 5, and at the same time, the two cylinders on the front side The operating cylinder 38 stops the telescopic operation of the rod, and continues to operate the cylinders 27a,
27b is retracted, and the small cylinder 35 on the front side is retracted to remove the scrapers 34a ₁ to a ₈ , 34'.
Reverse and return while opening b ₁ to _{b 8} . After a slight delay, the scrapers 34'a ₁ to a ₈ and 34'b ₁ to b ₈ also cross the center line of the pressing plate 5, and immediately after that, the cylinder 2
At the same time as the extension of the rods 7'a and 27'b is completed, the two working cylinders 38 on the rear side also stop extending and retracting the rod, and then the cylinders 27a and 27b are retracted, and the small cylinder 35 on the rear side is shortened and the scrapers 34'a ₁ to a ₈ and 34'b ₁ to b ₈ are opened while returning to the retracted position.

The lees P that has adhered to both sides of the pressing plate 5 in this way is peeled off in an appropriate divided state by the lees cutting bar, and is passed through a separate lees receiving device (not shown) or directly onto a conveyor (not shown) provided below. and will be carried out as appropriate.

The front and rear peeling devices 26, 26' are driven by the prime mover 17 in opposite directions to separate the frame-shaped frames 1a, 1b.
Retract from the medial line to the external position.

This completes one peeling operation, and then the above-mentioned operation is repeated, starting with the separating movement of a new pressing plate 5 to a predetermined position by the separating device.

Note that the scraper holding members 33a, 33b,
Although the wire rope 36 is used for the reciprocating movement of the actuators 33'a and 33'b, other actuation mechanisms such as a cam linkage mechanism may be used in the same manner.

The scraper vibrating device can also be configured such that one end is fixed to the upper and lower parts of the scraper holding member, respectively, and the other end is connected to the ends of both rods of a cylinder with double rods via a sprocket to perform both reciprocating and forced movement. It is possible to implement

As described above in detail, when using the device of this invention,
Each scraper provided in the peeling device is attached to the advancing/retracting member so that it can swing left and right and reciprocate up and down. The left and right swinging of the scraper advances the advancing/retracting member from a state in which the tip blade portion is in contact with the squeezing plate or filtering plate, and each scraper is reciprocated up and down a short distance via the scraper holding member. Therefore, even if the edge of the lees forms a slope, the vibration of the scraper is transmitted to the lees, allowing the tip blade portion to sharply bite into the edge of the lees reliably. Furthermore, even if there are hard parts of the lees here and there, this vibration allows the lees to be completely peeled off without leaving any unpeeled parts.
