Description
SPECIFICATION
Continuous Conveyance System
This invention relates to a conveyance system whereby a large volume of bulk load supplied continuously from a belt conveyor or other means can be conveyed continuously to a transfer section at any elevation.
As means for conveying loose bulk to an elevated position, there are known typically a bucket conveyor system comprising a series of buckets adapted to an endless chain or chains passed round a pair of upper and lower chain wheels and a belt conveyor system disposed with a gentle inclination. However, according to the conventional bucket conveyor system, the loose bulk accumulated at a low place is immediately raised up by the buckets to an elevated position, so that it is impossible with this system to continuously receive and convey to an elevated location the bulk supplied continuously from a belt conveyor or such.On the other hand, in case that the loose bulk is to be conveyed to an elevated position with the aid of the belt conveyor system, nobody can apply higher inclination than that as previously specified for installing any belt conveyor and this makes the whole conveyance system excessively elongated in the longitudinal direction. It therefore is pointed out with the hitherto known belt conveyor system that the same occupies a large area for installation thereof. In view of these facts the present invention is intended to eliminate the drawbacks and disadvantages inherent to the hitherto known conveyance system for loose bulk materials.
The primary objects of this invention is to provide a conveyance system which is capable of continuously conveying the continuously supplied loose bulk vertically or straightly up 8 down to any elevated or low location and which requires merely a limited space for its installation.
Another object of this invention is to provide a conveyance system capable of continuously conveying the loose bulk from a bulk receiving section to a transfer section which may be at any distance from said bulk receiving section.
Still another object of this invention is to provide a conveyance system whereby the loose bulk can be conveyed to any elevated or low location at any distance by suitably combining both horizontal and vertical transport lines.
Yet another object of this invention is to provide a conveyance system in which the conveyance containers can be moved while maintaining their horizontal posture through the course of transport from the bulk receiving section to the transfer section.
A further object of this invention is to provide a conveyance system which suffers little drop-out of the bulk from the conveyance containers in the course of conveyance.
Still another object of this invention is to provide a conveyance system according to which the loose bulk in any conveyance container won't be left over in the container but is entirely dropped out of the container.
An additional object of this invention is to provide a conveyance system which allows smooth, quiet and secure conveyance of loose bulk.
In order to accomplish the above-said objects, there is provided according to this invention a continuous conveyance system comprising in combination a series of ship-shaped conveyance containers for conveying loose bulk, with the body portion of each said container being formed from flexible plates with excellent releasability, two pairs of endless chains adapted to support and carry the front and rear portions of each said container, said pairs of endless chains consisting of a pair inner endless chains adapted to carry the front portion of each said conveyance container and a pair outer endless chains adapted to carry the rear portion of each said container, chain wheels around which said pairs of endless chains are passed, said chain wheels consisting of inner chain wheels around which said inner endless chains are passed and outer chain wheels around which said outer endless chains are passed, said both inner and outer chain wheels being secured to a common shaft at the rotatory section where the bulk is received, the rotatory section where the bulk is transferred and the rotatory section where the direction of movement of the endless chains is merely changed by 900, said both inner and outer chain wheels being arranged horizontally while suitably spaced-apart from each other at the rotatory section where the conveyance system is switched from horizontal conveyance to vertical conveyance while maintaining the horizontal posture of the containers and the rotatory section where vertical conveyance is changed to horizontal conveyance, and a bulk discharge promoting device provided at the rotatory section where the bulk is transferred.
In order to ensure smooth, quiet and positive movement of said series of conveyance containers while carried by the endless chains, it is desirable that the inner and outer endless chains are passed round the respective chain wheels with a half-pitch offset from each other.
In this connection it is to be added that the both inner and outer endless chains may be arranged parallel to each other without any pitch offset, which are passed round the respective chain wheels.
As said above, the inner and outer chain wheels are spaced-apart horizontally from each other at the rotatory section where the horizontal conveyance of the containers is shifted to vertical conveyance while maintaining the horizontal posture of the containers and at the rotatory section where vertical conveyance is shifted to horizontal conveyance, and in this case, the distance between the horizontally spaced-apart inner and outer chain wheels is so set that it is equal to the distance between a protuberance pivotally secured to the front end of the container and another protuberance secured fixediy to the rear end of the container.
In order to prevent the loose bulk from dropping out of the containers during supply of the bulk into the containers or during movement of the containers, it is preferred that the flexible engaging plates are mounted to the front or rear end or to both ends of each said container.
For allowing positive transfer of bulk cargo in the containers at the bulk transfer section, it is desirable that a bulk discharge promoting device composed of a spindle-shaped roller is mounted on the shaft of said section and that a means for giving vibrations to the container body is also provided in said discharge promoting device.
Other objects and advantageous features of this invention will become apparent from the following detailed description of the invention and the appended claims.
The characteristic features and other peculiarities of this invention will be easily understood from the following description of the invention when taken in conjunction with the accompanying drawings in which like reference numerals are used throughout to designate like parts.

Figure 11 is a side view showing the
mechanism at and around the rotatory section D.
Fig. 1 is a side elevational view diagrammatically illustrating the conveyance
mechanism of the continuous conveyance system
according to this invention, and Fig. 2 is a plane view thereof. The rotatory section C positioned
beneath a belt conveyor F is composed of a shaft
4 and a pair of inner chain wheels 2, 2 and a pair
of outer chain wheels 2', 2' mounted toward both ends of said shaft 4 as shown in Fig. 3, and both ends of said shaft 4 are supported by bearings 3, 3 secured to the casing 14.
The rotatory section C' is of the same mechanism as the section C. The rotatory section
C" is also the same in mechanism as the section
C, but in this section C", as shown in Fig. 10, cutouts 1 2 are provided suitably between the teeth of the inner chain wheel so that the connecting element 5' connecting the outer endless chain 1' and the conveyance container E (as further described later) will not interfere with the teeth of the inner chain wheel when said element 5' passes said section C".
The rotatory section D is also substantially same in structural mechanism as the section C, but in this section, a driving chain wheel 2" is secured to one end of the shaft 4 and connected to a motor M through reduction gearing (not shown). Also, a cargo discharge promoting device 13 is secured to the central part of said shaft 4, said device being arranged to abut against the bottom of the container E to give impact force thereto orto push up the button of the container to discharge out the material (bulk) therein.
The rotatory section A consists of a pair of shafts 4', 4' and a pair of outer chain wheels 2', 2' mounted on said respective shafts 4', 4' which are supported at their ends by the respective bearings 3, 3. The rotatory section B also comprises a pair of shafts 4", 4" on which the inner chain wheels 2, 2 are mounted, respectively, said shafts being supported at their ends by the respective bearings 3, 3. The rotatory section A' is of the same mechanism as the section A, and the rotatory section B' has the same mechanism as the section B. It will be easily understood from the accompanying drawings that the distance between the sections A and B and between the sections A' and B' is equal to the distance between the shafts 10 and 10' passed horizontally across the container E.
In the conveyance system according to this invention, said rotatory sections C, A, B, A', B', D,
C" and C' are disposed at the predetermined positions shown in Fig. 1, and the inner endless chains 1 are passed round said sections C, B, B',
D, C" and C" while the outer endless chains 1' are passed round the sections C, A, A', D, C" and
C'. Aiso, both sides of the front end of each conveyance container E are joined to two lines of inner endless chains 1, 1 through the connecting elements 5, while both sides of the rear end of the container are joined to two lines of outer endless chains 1', 1' through the connecting elements 5', thereby arranging a plurality of containers like a train between the parallel lines of endless chains.
Because of the above-described arrangement of the respective rotatory sections with the endless chains passed therearound, the conveyance containers E arranged in train are allowed to move horizontally at each horizontal transport section and to rise up vertically while equidistantly spaced-apart from each other and maintaining a normal horizontal posture at each vertical transport section.
In the rotatory section C", each container E passes i.n a turned-over condition as so is the connecting element 5' which connects said container E to the outer endless chains 1'. In this case, therefore, there is a possibility that said connecting element 5' might interfere with the chain wheel 2 between the teeth thereof. In order to avoid such interference, cutouts 12 are suitably provided between the teeth of each chain wheel 2.
Also, in order to ensure smooth and secure movement of the endless chains, the inner and outer chain wheels are arranged such that their corresponding teeth are shifted by a half-pitch from each other at each rotatory section, and hence the inner and outer chain wheels are engaged alternately with the endless chains.
It is to be noted, however, that the both inner and outer chain wheels may be arranged parallel to each other without any pitch offset therebetween.
Figs. 4 to 9 diagrammatically illustrate the connection of the conveyance container E with the inner and outer endless chains 1, 1'. The container E comprises a flexible rubber-made intermediate plate 1 5 extending between both side walls, with both edges of said plate being securely held by the bent portions 16, 1 6 at the lower ends of both side walls and presser plates 1 7, 17, so that the body portion 9 of the container
E is ship-shaped. At the upper parts of both side wall portions of the container E are provided the front protuberances 8 which are pivotally secured by bolts 1 8. The rear protuberances 8' are fixed by welding to the container side walls.In the drawings numerals 7, 7' indicate bolt holes formed in the respective protuberances 8, 8', and 6 is a rubber-made engaging member secured to the front portion of the container body 9 by adhesive, bolting or other means. This engaging member 6 has the role of filling up the space produced between this container and the adjoining one.
It will be noted that the front portion of the container E is connected to the inner endless chains 1 by means of the shaft 10 passed through said round holes 7 and connecting elements 5, while the rear portion is connected to the outer endless chains 1' by means of the shaft 10' passed through said round holes 7' and connecting members 5'.
Now, the operation of the conveyance system according to this invention is described with
particular reference to Fig. 1. When the motor is started to let the inner and outer endless chains 1, 1' move in the direction or arrows, the containers
E arranged in train move horizontally in the
direction of arrow at the lower horizontal
transport section.At the vertical transport section,
since the inner endless chains 1 are passed round
the inner chain wheels 2 at the rotatory sections
B, B' and the outer endless chains 1' are passed
round the outer chain wheels 2' at the rotatory sections A, A', the containers E rise up vertically while spaced-apart from each other vertically and maintaining the horizontal posture, and upon reaching the top of the ascending line, each container E is turned 900 at the rotatory sections
A', B' and move forward horizontally in the direction of arrow.Then each container E is inverted at the rotatory section D to move horizontally in an inverted state and is further turned 90" at the rotatory section C" to move downwardly in a posture shown in the drawing, and upon reaching the rotatory section C', each container is further turned 900 to move toward to rotatory section C.
Thus, according to the system of this invention, the bulk such as powder is continuously dropped from a belt conveyor F into each conveyance container E which has just reached the lower horizontal transport section, and during this operation, no drop-out of bulk is caused owing to the engaging member 6 provided to each container E to fill up the space between the adjoining containers. Each container E which has thus been loaded with bulk moves on horizontally, then rises up vertically along the ascending line at the vertical transport section and then changes into horizontal movement at the upper horizontal transport section.When the container E is inverted at the rotatory section D, the bulk in the container is perfectly discharged out, with no leftover in the container, by the action of the discharge promoting device and is successively dropped onto a belt conveyor G disposed below the rotatory section D.
It is to be added that the container E can maintain the horizontal posture during passing through the said lower rotatory sections A, B as well as the said upper rotatory sections A', B' owing to the fact that the inner and outer chains 1, 1' are arranged at a distance therebetween, which corresponds to that between the front and rear protuberances 8 and 8' or the front and rear connecting members 5 and 5'.
Further it is to be added that the container E can pass smoothly through all the rotatory sections C, C', C" and D, because the protuberances 8 are pivotally moved so as to correct the reduced distance between the connecting members 5 and 5', the said reduced distance being caused during the passage through the rotatory sections.
The body of the container used in the transport system of this invention is preferably constituted from rubber plates, laminate plates formed by bonding a thin flexible metal plate to the underside of each rubber plate, plates made of an elastic synthetic resin with excellent releasability, or elastic plates provided with a releasing layer on the surface. Use of such container plates allows absorption of any metallic sound produced during operation of the system. Also, owing to water repellency of said container plates, even moist bulk can be perfectly discharged out of the container without causing adhesion of bulk to the container wails.Further, bulk is urged to gather
centrally in the ship-shaped container, without
adhering to the container walls, during movement
of the container, and when the container is inverted at the rotatory section D, bulk is perfectly
discharged out without adhering to the container
bottom under the action of the discharge
promoting device.
The discharge promoting device, as best
shown in Fig. 6, comprises a spindle-shaped roller
mounted on a shaft. In order to better the
discharging action, it is recommended to provide
unevenness on the surface to produce a sort of
vibration.
Figs. 6 and 11 show the deformed condition of
the container plate at the inversion section.
Other features of the continuous bulk transport
system according to this invention are as follows:
(1) A great volume of bulk can be transported
not only vertically but also at any inclination.
(2) At the horizontal transport section, no drop
out of bulk such as powder is caused because an
engaging member made of a rubber plate or such
is provided to each transport container such that
said engaging member with engage or overlap
with that of the. adjoining container or directly
with the adjoining container, and hence high
transport efficiency is ensured.
(3) The installation area required for the system
of this invention is far smaller than that required
for the conventional belt conveyor owing to the
fact conveyance can be effected in the vertical
direction.
(4) It is possible to transport bulk from an
elevated location to a lower place by performing
the reverse operation.
Having the above-described features and
effect, the transport system according to this
invention can be applied for a variety of uses,
such as for stowing and unstowing the ship's hold with bulk, conveyance of sand in underground
construction work, conveyance of ores in mines,
etc.
The foregoing description of the invention and the accompanying drawings are merely intended to be illustrative, and it will be obvious that various changes and modifications can be made
in the above-described arrangements without departing from the spirit of the invention and the appended claims.
