Description

[Detailed Description of the Invention] This invention relates to a device that scrapes laminated pulp from above to a predetermined thickness and supplies it to a pulper or poacher.

This kind of laminated pulp scraping and feeding device was developed by Jitsukasho.
This is known from Japanese Patent No. 49-73174, in which an inverted L-shaped horizontal arm is provided at the upper end of an upright frame so that it can be moved up and down, a piston cylinder is fixed parallel to the horizontal arm, and a scraper is provided at the end of the piston. Load the laminated pulp on a trolley under the horizontal arm, lower the horizontal arm a little, and move the piston back and forth once each time. It is designed to be scraped off while being peeled off with a scraper.

However, this is because after the piston advances from the cylinder and scrapes off a certain thickness of laminated pulp with the scraper, the next time the piston retreats, the scraper returns while scraping the top surface of the remaining laminated pulp, resulting in rapid wear. At the same time, it damages the pulp fibers. or,
The scraper requires force to peel off the laminated pulp by pushing it horizontally from above to a certain thickness.

This invention was developed to eliminate the above-mentioned drawbacks, and consists of a front frame that is installed near the pulp receiving object such as a pulper or poultry, and a rear frame that is installed further away. and a lifting platform which can be raised and lowered and which is installed between the middle stages of both frames, and which is located above the lifting platform and whose rear end is supported by the upper end of the rear frame, and whose front end is placed on the front frame from the rear end. a support body which is supported at a high height and is installed between the two frames with an upward slope in the front; and two upper and lower shafts each having a chain wheel at each end and provided orthogonally at the front and rear of the support body. , upper and lower endless chains that are stretched between the chain wheels on the front and rear upper shafts and between the chain wheels on the lower shaft, and are driven in circulation so that each lower band moves forward, and each of the upper and lower endless chains. and a vertical scraper whose upper half is fixed at the same position, each scraper has a claw protruding forward at its lower end, and the front frame receives the front surface of the laminated pulp placed on the lifting table. Equipped with a contact plate,
The upper edge of the abutment plate is characterized in that it substantially matches the level of the pawl when the scraper starts moving forward.

In other words, according to the present invention, when the scraper moves forward, it bites its claws into the top of the laminated pulp at a certain thickness, scrapes it off, and feeds it into the pulper, etc. At the end of the forward movement when the mounting position of the scraper relative to the chain moves from top to bottom around the front half of the chain wheel, and at the beginning of the backward movement, the scraper rises, and as it retreats in the elevated state, the remaining laminated pulp is removed. The upper surface is not scraped, and the forward-facing claw at the lower end of the scraper lifts the rear end peeled from the top of the laminated pulp when it rises at the end of the forward movement, and securely drops it into the object to be supplied. Furthermore, since the support is tilted forward and upward, and the scraper advances forward and upward along the slope of the support, it does not require much force and is easier to peel compared to pushing horizontally parallel to the top surface of the laminated pulp. It can be peeled off, and a motor with low horsepower can be used to drive both the upper and lower endless chains, reducing running costs. Further, the abutment plate of the front frame allows the scraper to reliably remove only the pulp layer above the upper edge of the abutment plate, and supplies the appropriate amount to a pulper or the like.

An illustrated embodiment will be described below.

A indicates an object to be supplied with pulp, such as a pulper or poacher, and 1a and 1b indicate a front frame located near the object and a rear frame installed away from the object. Both frames 1a and 1b are gate-shaped, and a lifting platform 2 is provided between the two frames. The elevating table 2 is a well-known table consisting of a lower table 2a fixed between both frames, and a table 2b that can be raised and lowered and installed on the lower table via a pantograph operating device such as a pantograph or a piston cylinder. A roller conveyor 2' is provided.

The laminated pulp is approximately square with a side of 60 to 90 cm, a thickness of 50 to 60 cm, and a weight of 200 to 300 kg. To transport it onto the table, the table must be lowered to its lowest position, and the pulp must be placed on a belt-type inclined conveyor 3. increase.

A support body 4 is provided across the upper ends of both frames 1a and 1b. The rear end of this support body is pivotally connected to the rear frame 1b by a hinge 4a, and a pin 4b protrudes from both left and right sides of the front end, and a bolt 5 with this pin rotatably inserted into a cylindrical part at the upper end is attached to the front frame. 1a
Pass it through the long hole in the front-rear direction at the upper end and tighten it with a nut, thereby tilting the support body upward in the front direction. The angle of inclination of the front upward movement can be adjusted by adjusting the amount of protrusion of the bolt 5 that protrudes upward from the upper surface of the front frame.

At the front and rear of the support, a pair of upper and lower shafts 6a, 7a and 6b, 7b are orthogonally supported by bearing plates, and chain wheels 8a, 9a and 8b, 9b are fixed to the left and right ends of the shafts, respectively. An endless chain 10 is installed between the upper front and rear chain wheels 8a and 8b, and an endless chain 11 is installed between the lower front and rear chain wheels, and a scraper 12 facing vertically is placed at the same position on the side of each chain 10, 11. Fix the upper parts respectively. As shown in the figure, the upper side of the lower chain 11 is located directly below the lower side of the upper chain 10, and the chain is fixed at a fixed position 10' where the upper part of the scraper is fixed.
11' is located below both chains, the lower part of the scraper projects downward from the lower side of the lower chain 11. Therefore, the shafts 6a and 7a are rotated in the same direction by the motor and reducer M provided on the support 4,
When the upper and lower chains 10 and 11 are circulated so that their lower sides move forward and their upper sides move backward, the support body 4
As mentioned above, the scraper 12 advances forward upward according to the slope, and the fixed positions 10' and 11' are at the end of the forward movement of half a revolution around the front chain wheels 8a and 9a. At the beginning of the backward movement, the scraper rises and then moves backward downward, and in the same way, the fixed positions 10' and 11' move half a circle around the rear chain wheels 8b and 9b, at the end of the backward movement, and at the beginning of the forward movement, they descend again. move forward.

In this embodiment, the scraper consists of a thick iron flat bar, and a round iron bar with a sharp tip protrudes forward at the lower end as a claw 13 that bites into the upper rear surface of the laminated pulp as it moves forward. It is fixed.

Arms 14 are made to protrude upward and downward from the left and right sides of the support body 4, and sliding contact plates 15 are attached to the arms 14, on which the lower bands of the left and right upper and lower chains slide against the lower surface. Prevents the lower band of the chain from loosening when pressing on the upper layer.

Further, an abutting plate 16 is fixed between the left and right legs of the front frame 1a to receive the front end of the laminated pulp carried onto the table of the lifting platform. This contact plate 16
The upper edge 16' of is placed approximately at the level of the pawl 13 when the scraper begins to advance.

The lifting and lowering operation of the lifting platform 2 may be performed manually,
May be automated. In this embodiment, a phototube 17 for detecting the upper surface of the laminated pulp is placed at a level above the upper edge 16' of the contact plate 16, for example, at a height of about 7 to 8 cm, and the scraper advances once to remove the contact plate. When the upper layer of the laminated pulp above the upper edge is scraped off, the phototube detects this and commands the operating device of the lifting platform to rise, which causes the lifting platform to rise and the new upper layer of the laminated pulp to be placed in the light receiving path of the photocell. If it is blocked, the lift of the platform will stop. Of course, the present invention is not limited to this, and a micro switch or the like may be operated when the scraper retreats to raise the platform to a certain height.

As a result, as described above, the endless chains 10 and 11 are driven in circulation by the motor and reducer, and the claws 13 of the scraper, which advances forward and upward, bite into the laminated pulp P at a predetermined thickness position, and the scraper is moved to this predetermined thickness. The upper layer is pushed forward while being peeled upward from the layer below it, and as it rises at the end of the forward movement, the rear end of the upper layer is lifted and dropped into the object A, and then separated above the stack. By repeating this process, the laminated pulp on the table can be fed from above to a pulper to a predetermined thickness.

Preferably, the pantograph is completely moved when the lifting table is such that the upper surface of the roller conveyor 2' on the table is slightly above the upper edge of the abutment plate and the lower end of the scraper 12 advances so that it almost touches the upper surface of the roller conveyor 2'. When the scraper starts moving forward in this state, the roller conveyor 2' rotates at a circumferential speed that is approximately the same as the forward speed of the scraper, and the roller conveyor 2' rotates at a circumferential speed that is approximately the same as the forward speed of the scraper. To supply the remaining laminated pulp loaded to a pulper etc. in cooperation with a scraper without leaving it behind.

When there is no more laminated pulp on the lifting table, the circulation drive of the chain is stopped, the table of the lifting table is lowered to the lowest level, the next layered pulp is carried onto the table, and then the circulation driving of the chain is restarted.

In order to efficiently load the laminated pulp onto the inclined conveyor 3, a fixed table 18 having a roller conveyor 18' on the upper surface adjacent to the lower end of the inclined conveyor 3
, and then place multiple pieces of laminated pulp, such as a forklift, on top of it.

Supports 19 are erected at the four corners around the fixed base, and for example, cross beams 20 that can be raised and lowered along the supports are provided between the front left and right supports and between the rear left and right supports, and each cross beam 20
A piston cylinder 21 is installed facing each other,
A plate 22' having a claw 22 that bites into the laminated pulp is fixed to each piston end. In order to raise and lower each cross beam 20, for example, a screw shaft 23 is rotatably supported along each support, and the four screw shafts are simultaneously rotated forward and reverse by a motor, reduction gear, etc. using bevel gear transmission, etc. Screw the screw shafts along the left and right columns into the left and right ends of the front cross beam, and screw the screw shafts along the rear left and right columns into the left and right ends of the rear cross beam. As a result, the pistons 21 of the front and rear cross beams are projected, the claws 22 are bitten into the front and back of the second laminated pulp from the bottom, and in this state, the cross beams are slightly raised, and the bottom laminated pulp is tilted by the roller conveyor 18'. Transfer to conveyor 3,
Then, the cross beam is lowered, and the second layer from the bottom is lowered onto the fixed table, and the plate 22' is retracted by the piston cylinder 21, and the cross beam is raised a little, and the second layer from the bottom is placed at the bottom. The user points the claw 22 at the user.

Then, as mentioned above, when the table of the lifting platform 2 is raised to the highest level and there is no more laminated pulp on it, the chains 10 and 11 are stopped, and the table 2b is lowered to the lowest level.
At the same time, the cross beam 20 engages the claw 22 into the second pulp laminate from the bottom on the fixed table and lifts it up, and then the roller conveyor 18' on the fixed table drives the bottom laminate pulp onto the inclined conveyor. When the pulp is sent out and placed on the inclined conveyor to some extent, the inclined conveyor 3 and the roller conveyor 2' on the lifting platform are driven, and when the laminated pulp is completely transferred from the fixed table onto the inclined conveyor, the roller conveyor 18 on the fixed table is driven. ' is stopped, and just before the leading laminated pulp on the inclined conveyor transfers onto the table of the lifting platform and contacts the contact plate 16, the inclined conveyor 3 and the roller conveyor 2' on the table are stopped.
After a short delay, the table rises and the chain circulates again. Also, when the roller conveyor 18' stops, the horizontal beam above the fixed table descends to unload the laminated pulp that was being lifted, and the unloading is completed. Tsutara piston 21
Then, the plate 22' is retracted, the pawl 22 is raised to face the second laminated pulp from the bottom, and the process is automatically or semi-automatically performed, and several pieces of laminated pulp are stacked on a fixed table using a forklift or the like. It is extremely efficient and labor-saving to deliver laminated pulp to a predetermined thickness by simply
It can be supplied to pulpers and portiers.

Incidentally, since the laminated pulp is usually packaged, it is sufficient to unpack it while it is on the inclined conveyor and stopped.
