Conveyor belt sushi in Japan
Conveyor Belt sushi, known there as ‘kaiten-zushi’ (回転寿司) is a popular way of eating sushi in Japan. These photos are from one of the Hamazushi restaurants which you can find all over Japan.
Above is one of the seating booths. There is a Conveyor Belt running by your table with many dishes rotating round. You can pick what you want off the conveyor belt.
Here is a closer view of what it looks like from your seat. Above the conveyor belt is a list of all the dishes, a touch screen for ordering items if you can’t get them off the belt, and cutlery.
Below the Conveyor Belt are some condiments, and a hot water tap. With the hot water tap you can make yourself some free powdered tea. You need a small spoon of the green powder (it is very strong so don’t take too much), then you push your cup against the black button to get the hot water.
When you enter you are given a card with your table number. You’ll need to give it back after your meal so they know which table you were sitting at.
If you go at a busy time the dishes will be plentiful and fresh from the kitchen. If you go at a quite time there might not much much of a selection, and the food which is on the belt might be a bit old. It is not just sushi on the conveyor belt; you’ll also find cartons of soft drink and desserts.
Don’t worry though if you can’t see what you want, as you can order anything on the menu from your own touch screen. All the dishes are numbered on the menu, so you can quickly flick through the touch screen system to select which dish you want, and how many of them you want. They will be freshly prepared for you and put onto the belt.
They are put onto special ‘customer order’ plates, which have some kind of sensor in them. When the plate gets near your table, your screen will start beeping. It will even flash a photo of the dish on the touch screen in case you forgot what you ordered.
It is therefore very important that when taking ‘non ordered’ food from the belt that you don’t take them off these ‘customer order’ plates. You’ll be stealing someone elses order if you do!
A quick note for vegetarians – there are some things you can eat but not very many. Most of the dishes are fish (obviously), but even some of the non-fish dishes have fish flakes, or fish dashi on them so you have to be very careful.
Optional belt Required
Optional Belt:
1, accurately specify the name of the material nature. Especially particle size, temperature, can have acid, alkali and other corrosive and special requirements. Heat-resistant Conveyor Belt, such as the use of temperature to show.
2, indicating the specific applications, requirements specifications (width, length, number of layers, thickness, etc.), especially the use of temperature and heat-resistant Conveyor Belt volume size.
Storage:
1, the Conveyor Belt in the transport and storage, should be kept clean to avoid direct sunlight or rain and snow soaked shower, prevent acid, alkali, oils, organic solvents and other substances in contact, and one meter away from the heating device.
2, the conveyor belt when the warehouse storage temperature should maintain a 18-40 ℃, relative humidity should be maintained at 50 – 80%.
3, the conveyor belt during storage, the product must be placed into a roll, not fold, flip a conveyor belt should be on a quarterly basis.
Belt use:
1, to prevent the conveyor belt load to start.
2, the conveyor belt deviation occurs, it is timely to take measures to correct it.
3, different types of layers specifications should not be connected with the use of conveyor belts, the joint preferably bonding method.
4, the conveyor belt of the type, structure, size, number of storeys shall use reasonable choice.
5, the conveyor belt speed generally not more than 2.5m / s, block degree, abrasive materials and the use of large fixed-pear low discharge devices should be used.
6, the roller conveyor belt drive pulley diameter and the relationship between fabric layers, the drive roller, bend the supporting roller and the roller groove angle of the transport requirements of the design requirements should be based on reasonable selection.
7, to the expected direction, the direction should be along the conveyor, the conveyor reduces material impact on the whereabouts of the chute should be adopted, reducing the distance gap materials; conveyor belt by the material section, should be shortened and the use of the buffer distance between rollers of roller For the leakage, belt conform to appropriate block of soft material plate, so as not to stall plate mark, scratch the surface of the conveyor belt.
8, the conveyor in use, the lack of any roller is necessary to add and repair; roller covered by material, resulting in rotation not working, to prevent leakage of material between the cards in the drum and the belt, pay attention to the lubrication of conveyor belt moving parts, But not oil belt.
9, to avoid the conveyor belt being rack, post or block material block to prevent the misfortune to scratch the rip, when the local damage that conveyor belt, rayon and timely application of patches, so as not to expand.
Steep sidewall conveyor belt and Selection Caution
1, steep wall storage and use of conveyor belt and heat conveyor belt with the same common.
2, inclined conveyor belt more than 70 degree angle wall should be covered with, (with the benefit of using the cover to prevent leakage of material damage on the base band; but also can increase the volume of material.)
3, inclined ribs on the roller conveyor belt requirements required is much higher than that, if the case of the same model with a flat belt use than the larger cylinder models.
4, baseband
Corrugated sidewall conveyor belt is mainly exposed to rally the base, but in the course of its lateral stiffness and the effect of the use of performance plays a big role. Such as the conveyor belt rigidity is too small, the transverse deformation of the conveyor belt, causing phenomena such as scattering materials. (Such as the selection of CC-56 cotton canvas core conveyor belt, tearing strength 56N/mm, at least 6 or more layers of the core layer – with 6 layers, thickness = 4.5mm plastic cover over the next thickness = 1.5mm plastic cover over .)
5, divisions, skirts
Skirts in the choice of partition should first consider the throughput conveyors, such as: skirt height, baffle spacing, the size of the effective bandwidth.
Mean anything abnormal sound transmission belt
Product:Conveyor Belt
Belt squeak squeaky sound, under normal circumstances that greatly reduce surface friction coefficient belt, has excessive wear. If the vehicle load, fat sound, one might observe with the drive belt, you will find belts, automatic belt tensioning device or the resistance on the belt tensioner or increase abnormally elastic. Most automatic belt tensioner and tensioner at the bottom between the arms, somewhere along the slide direction of the length of a set of belt wear indicator. The sign by the pointer and two or three tokens, which indicate the scope of work of the belt tensioner. If the pointer outside this range, then the belt is probably stretched too far, should be replaced.
In the automatic belt tensioner is not installed in the car, in the middle of the two pulley belt with a standard ruler to measure the elongation measurement. If there are differences with the standard value, the best replacement belt. If the drive belt elongation did not exceed its limit, so if your car is to install an automatic tensioner, you should focus on looking at it. First, start the engine, transmission as much as possible to the auxiliary loads (such as opening lights, air conditioning, turn the wheel, etc.), then observe the belt tensioner cantilever; in the engine work, hanging belt tensioner there should be a small tube Small amount of displacement.
If the belt tensioner cantilever does not move, shut down the engine, suspension control in the belt tensioner working manually move it within the schedule, about 1 / 4 inch displacement. If the cantilever can not move the belt tensioner, belt tensioner to show that the failure, and should be replaced; belt tensioners if the displacement of the cantilever more than 1 / 4 inch, indicating that the spring load is too small to make the belt slip, and then Measuring time, if still the case, only the replacement of the belt tensioner.
If the belt is not over-stretched, and the automatic tensioner good working condition, then take a look at the working surface of the belt is worn as smooth as mirror. This is typical of the excessive wear caused by belt in a load skidding, pulley off the surface of the paint is the best proof of skidding. If the belt ringing creak do only occur in wet weather, and the belt and pulley surface is relatively smooth. We do a similar test: Let aid agencies working under the load drive system, while throwing water bottles to the belt with a sprinkler, if there is noise, replace the belt.
Although long screaming or ear-piercing noise belt surface due to dirt or piles of sand, used the reverse installation of the belt issue will lead to a long belt or ear-piercing screaming noise, but usually due to improper assembly drive supporting institutions and Caused. If the noise occurs in a moving car on the near, it may be due to the original high-quality manufacturing plant caused by the assembly. Check you think may lead to failure of related components. If the noise occurs in a used car, then you should consider a number of subsidiary bodies related accessories drive if you want to completely replaced.
Careful observation may have replaced parts (such as the alternator, power steering pump, etc.), look at their mounting brackets are solid and reliable. Must also pay attention to whether the installation process washers or bushings leave, they may cause inaccurate pulley assembly. Between belt and pulley surface that stained with dirt or sand can also lead to the noise, so if the cars stay dirty work environment, check whether all the dirt on the surface of the pulley there. Purchase of the air boom has told me it is very necessary.
Take the timing gear belt, the adjustment immediately after installation. This is why the timing gear to indicate the direction of rotation causes the belt. If for other maintenance work to remove the timing gear belt after the installation of anti-fashion, and when you will hear the belt running sharp, piercing scream. You try to reverse the installation direction of the belt to see if the fault disappears. Hiss, rattle, growl or whine or hiss continuous rattle and with increased engine speed increases, it usually means short of oil bearing secondary transmission.
With a stethoscope, you can hear the noise further investigation. Remove the drive belt and then, turning his hand suspected fault in the components. If the rotation difficult or harsh sounds rough, issued rattle, do not hesitate to either replace the bearings, or replace the corresponding parts. But note that: every time you replace auxiliary transmission parts, do not forget to replace the belt tensioner and automatic tensioning device.
If, with the engine speed increases, the continuous roar gradually into whine, that will soon be the corresponding bearing failure. Repeat the test system at a critical time to avoid disaster. Rumble rumble is a more typical belt vibration and sound, especially in the secondary sector work load drive, when the engine reaches a certain speed, the noise will be significantly increased. The reason for such failure is due to drive belt generally too loose, the belt tension or tensioner too long, tension wheel damage.
As I said earlier, the auxiliary transmission system failures in a number of institutions are indeed more common models. The diagnostic techniques that can help you diagnose and eliminate the noise of such drive belt failure.
