Purpose of the invention (industrial field of application) This invention removes oysters, pearl oysters, other aquaculture shells, seaweed and other nets used for marine aquaculture of Fuji jars, kasane hairpins, oyster shells and other calcium-like deposits. The present invention relates to a device for crushing and removing.

(Prior Art) To remove these deposits, which have been known in the past, place the net with the deposits on a wooden base and be careful not to break the net with a hammer. The deposits are crushed and removed.

On the other hand, one of a pair of sandwiching rollers that are in contact with each other is used as a drive roller, and another rotatable roller is elastically pressed against this roller,
There was a device on the market where this was entrained around the drive roller by frictional force, but when a part of the deposit was large, the net was not conveyed and the lower roller It spun around and broke the net, making it impossible to operate. Further, if the holding pressure is increased, the net itself may be crushed.

(Problems to be solved) As described above, manual work is inefficient and requires skill, and in the known device, when the upper roller is separated from the lower roller, The conveyance force is weakened, the lower roller idles against the net and damages the net at a high rate, and the efficiency is poor, and it is almost neglected by users today.

B. Configuration of the Invention (Means for Solving the Problems) In order to achieve the above-mentioned object, the invention is an aquaculture system in which a pair of sandwiching rollers are provided at the top and bottom, and a cradle is provided at the loading side and the unloading side. In the net-adhesion removing device, the upper roller of the pair of rollers is mounted on the machine frame such that the bearing portion of the upper roller is vertically slidable and elastically biased toward the lower roller. The upper and lower rollers are independently or interlocked with each other so as to rotate the approaching portions in the same direction and at the same speed, and are connected to a drive source. The drive source is a reversible rotation motor, and a start / stop switch and A net-for-adhesion removing device for aquaculture, which is provided with a forward / reverse switching switch.

In order to achieve the above object, the stopper for restricting the lower limit position of the upper roller of the device for removing aquatic net deposits according to the present invention is provided in the machine frame so that the position is vertically movable. There is also.

Further, a foreign matter detection sensor is provided at a predetermined height from the carry-in side cradle along the vicinity of the carry-in side of the gripping portion of the pair of gripping rollers, and a control signal for reversely rotating or stopping the normal rotation state of the motor by this detection signal. In some cases, a part is provided.

In order to achieve the above object, the tactile sensation of the detection sensor of the apparatus for removing deposits of aquaculture nets according to the present invention is a horizontal bar extending along the holding portion, and a color that can be easily distinguished from other members. In some cases, it is characterized by

(Operation of the device) In the device of claim 1, which is constructed as described above, when the device is first operated, the pair of upper and lower gripping rollers are respectively connected to the drive source, so It is forcibly driven.

Then, fold the aquaculture net with attached matter according to the roller width and insert it between the pair of holding rollers from the loading side pedestal. When sequentially conveyed to the unloading side and passing through the pair of holding rollers, the above-mentioned adhered matter adhering to the net is crushed, shattered, and separated from the net.

When the deposits are large or when the folding part of the net is partly thick, the upper roller moves upward against the elastic pressing force, while the upper roller rotates with the lower roller, Transport the aquaculture net.

Further, when the net is caught between the pair of gripping rollers or when the worker feels a danger, the start / stop switch or the forward / reverse rotation switch is operated to stop or reverse the forward / reverse rotation motor, and Stop or reverse the gripping roller.

In the apparatus according to claim 2, the stopper that regulates the lower limit position of the upper roller moves up and down according to the thickness of the net supplying the position and the amount and kind of the deposits prior to the operation. After adjusting to the optimum position, operate this device.

If necessary, the position of this stopper is adjusted to the optimum position during operation.

According to a third aspect of the present invention, the drive source is a reversible rotation motor, and foreign matter is detected at a predetermined height position from the carry-in side cradle along the vicinity of the carry-in side of the sandwiching portions of the pair of sandwiching rollers. Since a sensor is provided and a control unit that reversely rotates or stops the normal rotation state of the motor according to the detection signal is provided, the net supplied from the loading side is partially entangled and passes between the pair of rollers. Is difficult to achieve, or when the operator's hand reaches the sensor position, the motor as a drive source stops or reversely rotates.

According to a fourth aspect of the invention, since the tactile sensation of the foreign matter detection sensor is a rod extending along the holding portion, and has a color that can be easily distinguished from other members, Work with the net that supplies the tactile sense and your own hands not touching it. When the net or hand comes into contact with the tactile sensation for some reason, the motor stops or rotates in the reverse direction, and the subsequent transportation of the net is stopped.

(Embodiment) Next, a representative embodiment of the present invention including all the claims will be described.

Embodiment 1 As shown in FIGS. 1 and 2, 10 is a pair of upper and lower sandwiching rollers, each of which has a surface layer made of hard synthetic rubber, and a bearing portion 11 of a lower roller 10a has a machine frame 12 The bearing portion 13 of the upper roller 10b is fixed to the vertical guide 14 provided in the machine frame 12 so as to be vertically movable.
The stopper 15 that determines the lower limit position is provided so that the position can be moved up and down with respect to the machine frame 12.

The stopper 15 will be described in detail. The upper end of the screw rod 16 whose lower end is fixed to the upper part of the upper bearing portion 13 has the machine frame 12
A nut that is a stopper 15 is formed on the upper side of the horizontal rail 12a by penetrating through the horizontal rail 12a that is a part of the above, and the position of the nut 15 with respect to the screw rod 16 is adjusted. Thus, the lower limit position of the upper bearing portion 13 can be adjusted.
Reference numeral 17 is a lock nut for fixing the nut 15.

A compression spring 18 is provided between the upper bearing portion 13 and the horizontal rail 12a, and the upper bearing portion 13 stops at the position where the stopper 15 contacts the horizontal rail 12a unless external force is applied. ing.

As shown in FIG. 3, the stopper 15 may be a bolt 15a screwed into the machine casing 12 below the upper bearing portion 13. The point is that the lower limit position of the upper bearing portion 13 can be limited. In the example of FIG. 3, the screw rod of FIG.
The member corresponding to 16 may be a mere guide rod.

The lower roller 10a is connected to a reversible rotary motor (preferably for three-phase or single-phase) 20 mounted on the machine frame 12 directly or through an appropriate transmission means 21 (for example, an endless chain drive mechanism). The upper roller 10b is also transmitted to the lower roller shaft via the intermediate shaft 22 and the endless chain drive mechanisms 23 and 24.
The endless chain drive mechanism 24 connecting the upper roller 10b and the upper roller 10b has a sufficient length to allow the upper bearing portion 13 to move up and down, and is tensioned by the tension sprocket gear 25. Therefore, it is preferable that the direction of the straight portion of the endless chain drive mechanism 24 is largely different from the sliding direction of the upper bearing portion 13.

The upper roller 10b is also driven by the second reversible rotation motor 20 and the pair of upper and lower holding rollers 10 are rotated at the same speed at the same speed, but the invention is the same. At this time, the above-mentioned endless chain drive mechanism 23, 24 is used. Needless to say, it is unnecessary.

Reference numerals 26 and 27 denote a loading-side pedestal and an unloading-side pedestal mounted on the loading and unloading sides at the height of the holding portion P of the pair of rollers 10.

Reference numeral 28 is a foreign matter detection sensor provided on the loading side cradle 26, and the horizontal bar 29, which is a tactile sensor, is the upper roller 10b.
It is provided along with, and when foreign matter comes into contact with this horizontal bar 29,
The foreign matter detection sensor 28 is configured by providing the microswitch 30 so as to emit an output signal. This foreign matter detection sensor 28
The whole is provided so that its position can be adjusted vertically with respect to the machine frame 12. The bar 29 is of a color that is clearly distinguishable from the rest of the device and the net to be treated, and is usually yellow, white or red. The horizontal bar 29 is preferably a roller provided rotatably with respect to the horizontal axis, and when a certain force acts on the horizontal bar 29 in the transport direction,
It is preferable that the horizontal bar 29 is rotated around the axis of the sensor 28 so that the sensor 28 outputs an output signal and the net being conveyed is slightly in contact with the sensor 28, and the sensor 28 does not output an output signal.

The reversible rotation motor 20 is provided with a start / stop switch 31 and a forward / reverse switching switch 32. These are the receiving pedestals
A start / stop push button 31a and a forward / reverse rotation switching button 32a, which are the respective input parts, are attached to a part of the machine frame 12 at a position where an operator on the 26 side can operate with one hand.

In the embodiment, this forward / reverse changeover switch 32
Further, a control unit C for rotating the reversible rotation motor 20 in the reverse direction manually or by an output signal of the foreign matter detection sensor 28 is connected.

In the illustrated example, the forward / reverse rotation changeover switch 32 is switched to the reverse rotation side, and then returned to the original normal rotation side, for example, after 5 to 10 seconds from the set value variable timer 33. The control unit C may also issue a signal for switching the start / stop switch 31 to the stop side.

Operation of Embodiment 1 In order to use this embodiment having the above-described structure, first, the net to be treated is folded slightly narrower than the width of the pair of gripping rollers 10, and the thickness and the amount or kind of the deposits are set. First, the position of the stopper 15 (or 15a) is adjusted to the optimum position according to the situation. Therefore, the holding portion P of the pair of rollers 10 is
Is in a state in which a slight gap is formed.

When this device is connected to a household single-phase or three-phase power supply and the power supply start / stop switch 31 is turned on by its start / stop push button 31a, the reversible rotation motor 20 rotates forward and the upper and lower rollers are rotated.
Both 10a and 10b are forcibly driven and rotate at the same speed.

Next, when the net to be processed is supplied from the top of the carrying-in side pedestal 26 to the holding portions P of the pair of holding rollers 10, the net is held and conveyed by the pair of holding rollers 10 while passing through the holding portion P. Further, the deposits adhering to the net are crushed and separated from the net, and as the net is carried out onto the carry-out side cradle 27, the separated shells and the like are also pushed out to the carry-out side cradle 27.

Depending on the thickness of the net supplied and the amount of the attached matter, the thickness passing through the gripping portion 29 changes, and the thickness is the stopper.
When it becomes thicker than the spacing dimension of the holding portion P of the roller which is regulated by 15 (or 15a), the upper roller 10b
Receives a force to move upward, its bearing portion 13 moves upward against the force of the compression spring 18, and the upper and lower rollers 10a and 10b are also transmitted by the chain drive mechanisms 23 and 24 during this time. Therefore, the net continues to rotate, and while the net is being conveyed by the pair of gripping rollers 10, the attached matter that receives a certain pressing force is crushed or crushed.

When this net is inserted between the pair of holding rollers 10 from the receiving side pedestal 26, the net to be fed becomes entangled and becomes abnormally bulky, or when the operator's hand touches the tactile horizontal bar 29, The foreign matter detection sensor 28 outputs an output signal, the forward / reverse rotation changeover switch 32 is activated, and the reversible rotation motor 20 reversely rotates for a very short time. During this time, the bulky net is corrected to a normal state, or the start / stop switch 31 is operated by its push button 31a to turn it off, and the bulky net is similarly corrected to a normal state. .

When the operator's hand touches the horizontal bar 29, the timer 33
Wait for the normal rotation operation to be resumed by automatically releasing the changeover switch 32 by the time-up signal.

Embodiment 2 This is shown in FIG. 4 and includes the inventions according to claims 1 to 3 which are simplified from Embodiment 1. The same reference numerals as in the first embodiment indicate the same constituent elements or members, and perform the same operation.

The difference is that when an abnormal contact pressure is applied to the horizontal bar 29 of the foreign matter detection sensor 28, this output causes the alarm device 35 to generate an output signal. That is, the alarm device 35 includes one or both of a blinking lamp and a buzzer.

Further, the forward / reverse rotation motor 20 can be manually operated only by the start / stop push button 31a for operating the start / stop switch 31 and the forward / reverse rotation switch 32 and the forward / reverse rotation switching knob 32b.
It is provided on the front of the.

The case in which the sensor 28 of the second embodiment is not provided and only the horizontal bar 29 is provided and is not particularly linked to the alarm device 35 is also included in the embodiments of claims 1 and 2. In this case, the horizontal bar 29
It is preferable to set the color so that it can be distinguished from other members.

Operation of Embodiment 2 In Embodiment 2 as well, the net to be processed is supplied from the loading side cradle 26 in the same manner as in Embodiment 1, the forward / reverse rotation switching knob 32b is switched to the forward rotation side, and the reversible rotation motor is pressed by the start / stop push button 31a. When the pair of holding rollers 10 is driven, the pair of holding rollers 10 rotates in the forward direction, and when the holding portion P is supplied with the net, the net holds the pair of holding rollers.
While being conveyed by 10, the deposits adhering to it are crushed and removed from the net.

During this process, the net to be processed becomes extraordinarily bulky, and when the operator's hand is pulled together with the net and hits the horizontal bar 29 hard, the alarm device 35 gives an alarm.

At this time, the operator should press the start / stop push button 31 with the free hand.
By operating a or the forward / reverse rotation switching knob 32b, the reversible rotation motor 20 is stopped or reversely rotated, and the pair of holding rollers 10 is stopped or reversely rotated.

Then, the net is re-arranged and the operation is restarted in the same procedure as the last time.

In addition, in the case where only the horizontal bar 29 is provided,
When the net is supported by this and feeding of the net becomes difficult or impossible, the same operation as in the second embodiment is performed.

C. Effect of the Invention In the device of this invention configured and acting as described above, since the upper and lower rollers 10a and 10b of the sandwiching roller 10 are both forcibly driven, the rollers 10a and 10b are in contact with each other. Even if it does not exist, it is possible to operate at the same speed completely synchronously, there is no risk of slipping on the net, and there is almost no risk of breaking the net.

Further, the upper and lower rollers 10b of the pair of upper and lower gripping rollers 10 are elastically equipped in the direction of the lower roller 10a. While sequentially transferring the net, an appropriate pressure is applied to the adhered substance, and the adhered substance is crushed or crushed.

The drive source is a reversible rotation motor 20, and when the net becomes abnormally bulky, conveyance by a pair of gripping rollers becomes impossible, or when the worker feels a danger, the worker immediately starts and stops switch 31 or forward and reverse rotation. Operate the switching switch 32,
It is safe to stop or reverse the pair of holding rollers 10.

In particular, since it can be reversed, it is easy to convey the net to be processed back to the optimum state and rearrange the form.

The stopper 15 for restricting the lower limit position of the upper roller 10b according to claim 2 is provided in the machine frame so that the position can be moved up and down. Since it can be kept moderate, there is no danger of crushing the net itself because it is too strong, and no extra pressure is applied to the pair of rollers 10 themselves when not in use, and there is no risk of part of the rollers 10 denting, and the device as a whole Lifespan is extended.

As in the apparatus according to claim 3, the drive source is a reversible rotation motor 20, and at a predetermined height position from the carry-in side pedestal 26 along the vicinity of the carry-in side of the sandwiching portions of the pair of sandwiching rollers 10. In the case where the foreign matter detection sensor 28 is provided and the control unit C that causes the forward rotation state of the motor 20 to reversely rotate or stop according to the detection signal is provided, the net to be processed is entangled with a large volume, Even if the hand reaches the vicinity of the holding roller 10, the reversible rotation motor 20 is reversely rotated or stopped, which is safe and there is no possibility of damaging the device itself.

In addition, the operator hardly needs to manually operate the switch during driving, and can concentrate only on adjusting the shape of the net, and the workability is very good.

The tactile sensation of the detection sensor is a horizontal bar 29 extending along the holding portion P, and has a color that can be easily distinguished from other members, as in the apparatus according to claim 4. The worker can recognize the danger enough by the color,
Attention is always alerted to this so that the net or hands do not come into contact with it, making it safer and improving work efficiency.

(Effects peculiar to the embodiment) In the embodiment 1 shown in FIG. 1, the stopper 15 locks the nut 15 exposed on the horizontal rail 12a of the machine frame 12 with the lock nut 17
Since it can be loosened and adjusted, the adjustment is easy and no special tools are required.

Further, since the control unit C capable of temporarily reversing the reversible rotation motor 20 by the output signal of the sensor 28 and the OR signal of the manual input signal is provided, there is no possibility that the net is supported by the pair of rollers 10 or the hand is caught. .

The upper roller 10b is driven by the endless chain drive mechanism 2
3 and 24, of which the chain of the endless chain drive mechanism 24 has a margin in length, and the direction of the linear part of the chain is largely different from the sliding direction of the upper bearing part 13, that is, the direction of the guide 14. Therefore, even if the upper bearing portion 13 moves up and down, there is no great difference in the size between the upper roller 10b and the intermediate shaft 22, and the chain drive mechanism 24 between them has the tension sprocket gear 25. The upper roller 10b can be surely rotated without any problem in driving.

In addition, if the position of the sensor 28 can be moved up and down with respect to the pedestal, the height of this sensor 28 can also be adjusted according to the size and thickness of the net itself so that the sensor 28 does not emit an output signal indiscriminately. You can

Also, in the case of the embodiment in which the horizontal bar 29 is a rotatable roller and the sensor 28 does not output an output signal unless a certain amount of force acts in the transport direction, the sensor 28 does not output an output signal unnecessarily, so that it is frequently When the pair of gripping rollers 10 does not stop, the work efficiency is good, the net is entangled, or the operator's hand pulls the net, and the horizontal bar 29
Since a considerable force is applied to the conveying direction, the pinching roller 10 surely stops at this time, which is safe.

In the device of the second embodiment shown in FIG. 4, there is no particularly complicated control unit, and the start / stop push button 31a and the forward / reverse switching knob 32b are used.
Is provided in the machine frame 12 on the loading side cradle 26 side, so that an operator supplying the net can easily and quickly operate the start / stop push button 31a and the forward / reverse rotation switching knob 32b.

If the horizontal bar 29 is provided without the foreign matter detection sensor 28, the operator can know that there is a limit of danger if the horizontal bar 29 is touched by the hand. It has the effect of becoming a gauge showing the limit of the bulkiness of the net. When these are colorfully colored, the guard effect is more remarkable.
