Abstract

PURPOSE:To make a motor compact and smooth and ensure the starting of a storage equipment for crushed ice or the like, by providing a scrape-off means driver with a clutch to connect the driver to the motor when it has reached prescribed rotational frequency. CONSTITUTION:When a motor 22 is started, it is rotated backward for a time set by a backward rotation time setting timer T1. After that, a delay by a time set by a forward rotation delaying timer T2 is effected, then turning the motor 2 forward. At that time, a clutch C1 remains disengaged. The clutch has such a construction that a secured boss and a rotatable wheel can be rotated relative to each other within a prescribed range of angle because of a stop pin and a slit until the motor 22 reaches prescribed rotational frequency. When the motor 22 is accelerated to the prescribed rotational frequency, the clutch C1 is engaged to connect the motor to a shaft 14 to rotate scrape-off blades 16 through a control section 20 and a geared motor 19 so that crushed ice is discharged. According to this constitution, the motor 22 is made compact and starting action is smoothed and ensured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is mainly aimed at temporarily storing powder and granular materials that, when stored, cause a bridging phenomenon in the storage room and become difficult to fall, such as crushed ice, balas, lime, etc., or flour and other powders. The present invention relates to a storage device for storing powder and granules that are easily consolidated.

■Prior Art As a storage device for crushed ice that is most likely to cause the bridging phenomenon when stored, the present inventor has developed a device with a structure shown in FIGS. 1 and 2.

In this storage device, a storage chamber 1 is formed so that its horizontal cross section becomes larger toward the bottom, and discharge conveyors 2 are arranged in multiple rows on the bottom surface. Discharge conveyor 2
When it is operated, the crushed ice 3 in the storage chamber 1 is scraped off from the bottom and discharged outside, and the storage chamber 1, whose horizontal cross-section increases as it moves downward, is prevented from sticking to the inner wall surface of the storage chamber. They move downward and are taken out in order from the bottom.

However, in a storage device with this structure, since the overall shape of the storage chamber 1 is formed in an upwardly tapered shape, the horizontal cross-sectional shape becomes smaller as the storage chamber becomes higher, and a storage device with sufficient volume compared to the height is not practical. There are drawbacks that are difficult to overcome.

The present inventor has developed an apparatus in which a crusher is disposed within a storage chamber and the stored material is forcibly scraped off regardless of the shape of the storage chamber.

A crushed ice storage device with a crusher is shown in FIGS. 3 and 4.

In this device, a crusher 4 discharges crushed ice from a conveyor 2h.
A discharge conveyor 2 discharges the crushed ice to the outside. The crushed ice scraped off by the crusher 4 moves laterally along the bottom surface inclined downward toward the discharge conveyor 2, is separated from the wall of the storage chamber, and is pressed against the crusher 4 by its own weight. .

Since this device has vertical walls, it has the advantage that the storage space can be increased in proportion to the height. It often occurred that this could not be started at all.

The inability to start the discharge conveyor 2 and the crusher 4 is a serious drawback that hinders the practical use of this type of device. This is because if it cannot be started, not only will it not be possible to take out crushed ice etc. when needed, but also the stored items in the storage room will not be able to be removed.
This is because the ice must be removed from the top using another method, or in the case of crushed ice, it must be melted and removed, and the function of the device will be completely lost.

Due to these factors, the motor for driving the discharge conveyor 2 or the crusher 4 has become extremely large, and due to the structure of forcing it to be driven by a large motor, the motor for driving the discharge conveyor 2, the crusher 4, and all of the components that support and drive them must be The disadvantage is that the parts are prone to failure, and the operating power is relatively small under normal continuous discharge conditions, and large torque is required only at startup, so a large horsepower motor is effective due to large load fluctuations. There was also the drawback of not being able to use it.

■ Purpose The present invention uses an extremely simple structure to increase the starting torque of scraping means such as discharge conveyors and crushers, effectively eliminates the initial inability to start, and securely removes stored powder and granules. To provide a storage device for easily solidifying powder and granular material that can be scraped off smoothly and efficiently using a small motor.

(3) Configuration Embodiments of the present invention will be described below based on the drawings.

The present invention drives a scraping means such as a discharge conveyor or a crusher through a clutch, and when started,
This device disconnects the scraping means from the drive motor, starts the motor without load, and drives the scraping means after the motor reaches a predetermined rotational speed, as shown in Figures 3 and 4. A structural storage device can be used as an example.

To further explain the storage device shown in FIGS. 3 and 4, this storage device includes a storage chamber 1 for storing powder such as crushed ice, and a scraping means disposed at the bottom of the storage chamber 1. A discharge conveyor 2 and a crusher 4 disposed directly above the discharge conveyor 2 are shown.

The storage chamber 1 is formed into an elongated rectangular horizontal cross section, and a crushed ice supply port 5 is opened in a part of the ceiling, and crushed ice made by an ice making machine 6 is supplied from the supply port 5.

The operation of the ice maker 6 is controlled by a level sensor 7 disposed above the storage chamber 1, and the ice making machine 6 is operated at a level below a predetermined level of crushed ice in the storage chamber 1 to store a certain amount of crushed ice in the storage chamber.

It is preferable to provide a crushing ice leveling means 8 in the upper part of the storage chamber 1. The leveling means 8 has leveling plates 10 fixed to four chains 9 at regular intervals, and two sprockets 1 arranged horizontally on both sides of the four chains 9 in FIG.
1 and the chain 9 is driven by the sprocket 11 to level the supplied crushed ice 3 horizontally.

The bottom surface 12 of the storage room 1 is sloped downward toward the central discharge conveyor 2, and the crushed ice scraped off at the center is
It slides on the bottom surface 12 under its own weight and is pressed against the crusher 4.

The angle of inclination of the bottom surface 12, that is, the angle with the horizontal, is usually determined to be 10 degrees or more, preferably 15 to 60 degrees, and optimally about 20 to 40 degrees. For example, it is made of a stainless steel plate with a smooth surface.

The outer periphery of the storage room 1 is surrounded by a wall 13 that is heat-insulated.

The discharge conveyor 2 is a screw conveyor, and this screw conveyor has a shaft 14 extending in the longitudinal direction of the storage chamber 1, and a spiral claw 16 is fixed to the surface of the shaft 14.

The discharge conveyor 2 is rotated by a driving member, and the driving member includes a clutch C, a reduction gear R, and a motor 22. The clutch C includes a clutch main body C1 and a reversing member C2 that reverses the rotation of the motor 22 at a certain period of time. - In FIGS. 3 and 4, the clutch body C1 is mounted within a sprocket wheel 35 mounted on the shaft 14 of the discharge conveyor 2.

The structure of the clutch body C1 is shown in FIGS. 5 and 6. This clutch body C1 is connected to the shaft 14 of the discharge conveyor.
a boss 37 that is fixed via a key 36 to the boss 3;
1 is equipped with a wheel 40 rotatably housed therein via two bearings 38 and 39, and the wheel is connected to a speed reducer via a chain.

As shown in the figure, the boss 37 has a disk-like shape as a whole except for the stopper portion, and a stopper 41 protrudes from a part of the circumference.

The wider the circumferential width of the stopper 41, the stronger it becomes, but the rotation angle between the post 3γ and the wheel 40 becomes narrower.

Therefore, the stopper 41 is attached to the pin 4 of the wheel 40.
The minimum width that can withstand even if 2 hits, for example, 3 all around
The width is determined to be 90 to 45 degrees relative to 60 degrees.

The wheel 40 has a cylindrical overall shape, teeth 43 that mesh with the chain are fixed to the outer periphery, and a pin 42 that penetrates in a direction parallel to the shaft 14 and hits the stopper 41 of the post 3T is fixed. There is.

The POS 3T and the wheel 40 can be rotated forward and backward by 270 degrees relative to each other, and after rotating 270 degrees in the forward or reverse direction, the wheel 4
The pin 42 of 0 hits the stopper 41 of the boss 37, and after that, the two rotate as one without rotating relative to each other.
That is, the clutch main body C1 is in a connected state.

When the clutch body C1 is built into the sprocket wheel 35 of the discharge conveyor 2, it is connected to the motor 22 via the reduction gear R.

Therefore, by the time the post 37 and the wheel 40 have rotated 270 degrees, the motor 22 has been rotated by a multiple equal to the reduction ratio, and after the motor 22 has rotated a considerable number of times, the clutch body C1 is connected, and the motor 22 is The discharge conveyor 2 is started in a high torque state close to the #A speed and in a state with large inertia. In particular, since the motor 22 is started with almost no load, it is accelerated to constant speed rotation in an extremely short period of time.

7 and 8 show another structure of the clutch main body C1. Like the clutch bodies shown in FIGS. 5 and 6, this clutch body C1 is also mounted within a sub-mount wheel 35 fixed to the shaft 14 of the discharge conveyor. , this clutch body C1ki
, a boss 37 fixed to the shaft 14 via a key 36, and a wheel 40 in which the boss 37 is rotatably housed, and the wheel 40 is connected to the speed reducer R via a chain.

The boss 37 is a city bottle 4 that protrudes from both sides and extends in the axial direction.
4 is fixed to the outer periphery, and the wheel 40 has an arc-shaped slit 45 cut through both side plates and along the locus of movement of the regular bin 44, that is, centered on the rotation axis. In the angular range in which the locking pin 44 moves along the slit 45, the boss 37 and the wheel 40 rotate relative to each other, and the positive pin 44 hits either end of the slit 45, causing the boss 37 and the wheel to rotate. It rotates integrally with 40.

Therefore, the operation of this clutch body C1 is controlled by the wheel 40.
Each time the wheel 40 and the boss 37 are reversed, the wheel 40 and the boss 37 rotate by a certain angle, the stop pin 44 moves from one end of the slit 45 to the other end, and then the two rotate together again.

That is, the clutch main body C1 is in a state where it is released by a certain rotation angle, and then it is in a state where it is connected.

In the discharge conveyor 2, one end of the shaft 14 is connected to a three-phase motor 22 serving as a driving means, and the motor 22 is rotated in the normal direction to discharge the crushed ice to the outside. When the motor 22 starts rotating the shaft 14 by the reversing member of the clutch, the motor 22 rotates the shaft 14 in the reverse direction for a certain period of time and then rotates in the normal direction.

When the driving means is an electric motor 22, the reversing member C2 includes a timer T1 and a changeover switch SO. Timer T
1 adjusts the reversal time at the time of activation.

A specific example of a circuit diagram of the timer Tl and the changeover switch SO is shown in FIG.

In FIG. 9, the electromagnetic filter TC1 of the timer TI is connected to the power supply through the main switch SM, and the b
The H point Tub is connected in series to the electromagnetic coil MC2 of the motor reversal relay.

Furthermore, the aH point Tla of the timer Tl is connected in series with the electromagnetic coil Tc2 of the timer T2 which delays the starting time of normal rotation. The a contact MC1a of a relay directly controlled by the main switch SM is connected in series to the b contact Tlb of the timer Tl, and this MC1a stops the operation of the motor 22 when the main switch SM is turned off.

The operation of this circuit is that when the main switch SM is turned on, the aH point MC1a of the relay is closed, and the electromagnetic filter MC passes through the bH point Tlb of the timer, which is maintained in the closed state.
2 is energized, the a contact MC2a for reverse rotation is closed, and the motor 22 is rotated in reverse.

At this time, immediately after starting, the boss 37 of the clutch body and the wheel 40 shown in FIGS. 5 to 8 are mutually rotatable, so the motor 22 is started with no load or a state close to it. After a predetermined number of rotations, the boss 37 and the wheel 40 are integrally connected, the clutch body C1 is connected, and the discharge conveyor 2 is reversed. Therefore, the set time of the timer Tl is set to a longer time than it takes for the motor 22 to start and the clutch body C1 to be connected.

When timer T1 reaches the set time, timer bH point Tlb
is opened, timer aH point Tia is closed, and timer T2 starts counting. In this state, timer T2
Since the a contact T2a of the timer T2 is open and the bH point Tlb of the timer Tz is also open, the motor 22 is not energized and this state continues until the motor 22 completely or almost stops.When the timer T2 reaches the set time, the timer T2 The a contact T2a is closed, and the motor 22 starts normal rotation. At this time, as well as when starting in reverse, the boss 3T of the clutch body C1 and the wheel 40 are rotatable by a predetermined angle immediately after starting, so the motor 22
The motor 22 is rapidly accelerated in a no-load state until the motor 22 rotates in the normal direction and the pin is hooked, causing the boss 37 and the wheel 40 to rotate together. After reaching a predetermined rotational speed, the clutch body C1 is connected, the discharge conveyor 2 is operated normally, and the crushed ice is discharged outside. When the main switch SM is turned off to stop discharging the crushed ice, the electromagnetic coil TC2 of the timer T2 is de-energized and the operation of the motor 22 is stopped. At the same time, the b contact T of timer TI
lb is closed, but the relay a connected in series with this
The motor 22 is not operated at d when the contact MC1a is opened.

As shown in FIGS. 5 to 8, the clutch main body C1 is in a state where it does not slip at all when it is in a connected state, and is in a state where it can rotate freely when it is not connected, and furthermore, the motor 22 is reversed for a certain period of time. According to a structure that stores sufficient kinetic energy and rapidly connects, it is possible to realize the feature that an extremely large torque is generated at the time of startup.

The crusher 4 shown in FIGS. 3 and 4 is.

A large number of scratching claws 16 are fixed to a shaft 15, and the plurality of shafts 15 are arranged horizontally and parallel to each other directly above the discharge conveyor.

Specific examples of the scratching claws 16 of the crusher 4 are shown in FIGS.
This is shown in Figure 2. Scratching claw 1 in Figures 10 and 11
6 is formed in a wide shape extending in the longitudinal direction of the shaft 15, and is 1iiiI! in the rotational direction. The contacting claws 16 are somewhat ramped. This crusher 4 has the feature of uniformly scraping off crushed ice over the entire length of the shaft 15 by being rotated.

The scratching claw 16 in FIG. 12 is a pin, and this pin is fixed around the shaft 15 according to the size of the crushed ice.

The pin spacing, H, is usually determined to be 100 mm or less.

A sprocket wheel 17 is fixed to one end of the plurality of shafts 15, and this sprocket wheel 17 is connected to the chain 1.
8 to a gear motor 19, which rotates all the shafts 15, thereby scraping off the crushed ice in the storage chamber from the center.

A clutch similar to that of the above-mentioned discharge conveyor can be used for the drive member of the crusher. In this case, like the sprocket wheel 35 of the discharge conveyor, the clutch body C1 can be built into the sprocket wheel 17 fixed to the shaft 15.

The operation of the gear motor 19 of the crusher 4 is controlled by the load sensor of the control member belt discharge conveyor 2.

FIG. 13 shows an example of the m-control member 20 and the load sensor 21 that control the operation of the discharge conveyor 2. In this figure, the load sensor 21 of the discharge conveyor 2 is a current sensor that detects the operating current of the discharge conveyor driving motor 22, and the control member 20 is controlled by the output of this current sensor.

For example, a meter relay can be used as the current sensor and the control member 20.

The current sensor outputs a signal corresponding to the load current of the motor 22, usually a voltage output signal proportional to the current. In response to this output signal, the control member 20 is turned on and the crusher 4 is operated when the motor is under a certain load, that is, when the discharge conveyor 2 is idle in the crushed ice or discharges a small amount of crushed ice. When the crusher 4 is operated and crushed ice is scraped onto the discharge conveyor 2, the discharge conveyor 2 sends out a large amount of crushed ice, and the operating current of the motor 22 increases. This is detected by the current sensor, the control member 20 is turned off, and the operation of the crusher 4 is stopped.

The operation of the crusher 4 can be stopped by detecting that the torque of the discharge conveyor 2 has increased, but it can also be stopped by the timer 23. In this case, the crusher 4 uses the torque of the discharge conveyor 2, that is, the motor 22
It is turned on when the operating current of the motor 22 becomes less than the set value, and then, for example, after 0.5 to 2 seconds, the timer 23 forcibly stops the operation even if the operating current of the motor 22 does not increase to the set value. let

If the operating time of the crusher 4 is controlled by the timer 23, the operating time of the crusher 4 is too long and the crushed ice is not crushed into small pieces.
There is no possibility that the discharge conveyor 2 will be overloaded with crushed ice. When the crusher 4 is in the off state, the discharge conveyor 2
However, according to this method, there is a time delay in increasing the torque of the discharge conveyor 2,
Even if the crusher 4 crushes a considerable amount of crushed ice, the driving torque of the discharge conveyor 2 immediately increases, causing the problem that the crusher 4 is operated for a longer time than necessary. Therefore, in the most preferred embodiment, the discharge conveyor 2
It is preferable that the crusher 4 starts operating when the torque is detected and the torque is below the set value, and the operation of the crusher 4 is forcibly stopped after, for example, 0.5 to 2 seconds using a timer.

When the operating time of the crusher 4 is set by the timer 23, the operation of the crusher 4 is stopped before the motor current of the discharge conveyor increases. 2. Immediately after the crusher 4 is stopped using this method, the current of the motor 22 for the discharge conveyor 2 is less than the set value, and the crusher 4 may be restarted. This problem is caused by another off timer 23.
The crusher 4 may be prevented from restarting for a certain period of time after the operation is stopped. The off-timer 23' is set to a time longer than the time required for the crushed ice scraped by the crusher 4 to be sent to the discharge conveyor 2 and for the current of the motor 22 to increase, for example, 0.1 to 10 seconds.

Also, if the set torque value of the control member 20 is kept low,
The amount of crushed ice in the discharge conveyor 2 is always small, the torque at the time of starting the discharge conveyor 2 is small, and the feature is that the discharge conveyor 2 can be started easily. In this case, since the discharge conveyor 2 discharges a fixed amount of crushed ice from the time of startup, the discharge amount can be determined by controlling the operation time of the discharge conveyor 2, and a fixed discharge characteristic can be realized.

In FIG. 14, the load sensor 21 is a torque sensor, and this load sensor 21 is fixed to the output shaft of the discharge conveyor driving motor 22, and the load sensor 21 is used to drive the discharge conveyor 2.
directly detects the rotational torque of The output signal of the load sensor 21 is sent to the control member 20, and based on the output signal of the load sensor 21, the control member 20 is turned on when the drive torque of the motor 22 is below a certain amount, and turned off when it is above a certain amount.

The shaft of the crusher does not necessarily need to be rotated, but can also be oscillated at a constant angle.

In FIG. 15, the motor 22 for driving the discharge conveyor is also used as the motor for driving the crusher 4. In FIG. The crusher shaft 15 is connected via a clutch 24 to a motor 22 for driving a discharge conveyor. The on/off state of the clutch 24 is controlled by the control member 20 . The control member 20 is controlled by an input signal from a load sensor 21.

The operation of the crusher 4 is such that when the load torque of the discharge conveyor 2 becomes below a certain level, this is detected by the load sensor 21, and the output signal of the load sensor 21 is used to control the control member 2.
0 connects the clutch 24 and operates the crusher 4.

The crusher 4 scrapes the crushed ice onto the discharge conveyor 2,
When the discharge conveyor 2 is in a state to send out a predetermined amount of crushed ice, the control member 20 and the clutch 24 are released to stop the operation of the crusher 4, thL, . . . This is repeated thereafter to take out the crushed ice.

The crusher 4 shown in FIGS. 16, 17, and 18 is
A shaft 15 is arranged vertically and moves along the discharge conveyor 2. The crusher 4 includes a traveling base 25, a gear motor 19 for driving a shaft, and a traveling motor 26 for moving the traveling base 25. The operation of the gear motor 19 for driving the shaft is controlled by the member 20. controlled by

The traveling platform 25 moves along a rail 27 fixed near the ceiling of the storage room in parallel with the discharge conveyor 2, and is driven by wheels 28 by a traveling motor 26 to travel.

The travel motor 26 is energized together with the gear motor 19 for driving the shaft, and the shaft of the crusher is rotated to move while scraping off the crushed ice.

However, this traveling motor 26 can also be turned on and off by detecting the driving torque of the shaft. In this case, a shaft drive gear motor 19 is used, similar to the discharge conveyor motor.
Detect the current with a meter relay, for example, and with this,
The gear motor 19 operates the travel motor 26 at a constant torque or less, and the gear motor 19 stops the travel motor 26 at a constant torque or less.

The crusher shown in FIG. 18 has two shafts 15 arranged in parallel, spiral claws 16 are fixed to both shafts, and the shafts 15 are rotated to scrape crushed ice upward.

According to this method, the scraped crushed ice is not compressed at the lower end, and the crushed ice can be continuously scraped up and down by the scraping claws 16 on the surface of the shaft 15.

19 to 23 show a crusher 4 whose shaft 15 can move up and down.

The crusher shaft 15 is parallel to the discharge conveyor 2, and both ends of the crusher shaft 15 are supported by bearings 29 so as to move downward in a vertical plane including the discharge conveyor 2, and the bearings 29 are fixed vertically. In order to move up and down along the guide rail 30,
It is connected to a string 31 such as a chain or wire. The string 31 is hung on a winch drum 34 connected to a motor 33 via a worm reducer 32, and the winch drum 34 drives the string 31 to move the bearing 29 up and down.

A gear motor 19 for driving the shaft is fixed to the bearing 29.
This drives the crusher shaft 15.

The gear motor 19 for driving the shaft of the crusher is operated at the same time as the motor 34 that moves the shaft up and down, or the motor 34 that moves the shaft up and down is the same as the motor 34 that moves the shaft of the crusher in the horizontal direction. It operates only when the driving torque is below a certain level.

As shown in FIGS. 16 to 23, in the case where the shaft 15 of the crusher 4 moves horizontally or vertically, when the shaft 15 of the crusher 4 is rotated without moving, the scratching pawl 16 of the shaft 15 is moved. The shaft 15 rotates lightly without scraping off the crushed ice. Therefore, the shaft 15 of the crusher 4 is rotated simultaneously with the operation of the discharge conveyor 2, the travel motor 26 or the motor 33 is operated when the rotational torque of the discharge conveyor 2 is below the set value, and after a certain period of time, the timer drive motor 2
It is preferable to stop the operation of the motor 6 or the motor 33, or to detect the torque of the discharge conveyor 2 and stop it when the torque of the discharge conveyor 2 exceeds a set value.

In the storage device shown in FIG. 24, a discharge conveyor 2 is disposed on one side of a storage chamber 1, and a bottom surface 12 is inclined downward toward the discharge conveyor 2.

(Effects) In the powder storage device configured as described above, the drive member of the scraping means is equipped with a clutch, and this clutch member does not connect the motor and the scraping means when the motor is started, so that the motor is unloaded or The specified rotational speed is smoothly and quickly reached with almost no load, and then the clutch is engaged and the scraping means is driven, so when the clutch is engaged, the motor is accelerated to a sufficient torque generation range, and the motor Since the inertial force is also quite strong, when the clutch is engaged, the motor activates the scraping means with extremely strong torque, and the scraping member, which is difficult to start when it is inside the solidified powder, can be easily and smoothly removed. Moreover, it is extremely effective and can be activated reliably under any circumstances.

A three-phase induction motor is often used as a driving member of this type of device. This type of motor has a fairly low torque at startup, that is, when the rotational speed is low, and the torque increases as it approaches the synchronous speed, so you can start the motor with no load and start it at a rotational speed that generates a large torque. The motor that starts the motor is very effective in making the most effective use of the characteristics of the motor.

Conventionally, the size of the motor was determined by the starting torque, so even though a very large torque was not required during operation, a motor with a considerably high horsepower was used, resulting in low efficiency in the use of the motor and power supply, and a reduction in equipment and running performance. The drawback was that the cost was high.In contrast, the storage device of the present application is reliably started with a small horsepower motor, so the small motor can always be used with high efficiency, and the motor and electric power can be used effectively. It is also extremely effective in reducing running costs and equipment costs.
