Description

[Detailed description of the invention] (Industrial application field) This invention is capable of transporting large numbers of foods, mainly fried tofu, immediately after cooking in oil, to the next process without disturbing the line while cooling and draining the oil. The present invention relates to conveyors, and particularly relates to a roller-type conveyor with a structure that allows for easy roller replacement and cleaning.

(Prior Art) When cooking a large amount of fried tofu, etc., a large number of doughs were put into an oil pot at the same time, and the dough was pulled up at the same time and transferred to a conveyor or the like to be sent to the next process. In order to transfer the fried tofu from the oil pan to the conveyor, conventionally a chute is provided that runs from the edge of the pan to the conveyor, and the fried tofu is dropped into this chute and transferred by sliding on the top of the chute to the conveyor. I was changing it.

(Problem that the invention aims to solve) It is better to place the fried tofu that has run out of oil as neatly as possible on the conveyor. However, with this conventional method, the sliding of the fried tofu is not uniform, so it is placed in a disorderly manner on the conveyor, and the oil also flows in the same direction, making it difficult to drain the oil, resulting in poor cooling efficiency and oil recovery. The efficiency was poor, and there were also problems such as oil sticking to the chute and making it slippery.

In addition, there was a problem in that, depending on the height difference and distance between the lifting position from the oil pot and the conveyor, a satisfactory inclination angle of the chute could not be obtained, making it impossible to obtain an appropriate sliding speed. Further, when using a roller type conveyor with a shaft fixed to a frame, there is a problem in that it is difficult to replace and clean the rollers.

As a roller conveyor that solves this problem, a roller conveyor in which rollers can be detachably attached from above is known from Japanese Utility Model Application Publication No. 55-140014. However, with the roller conveyor of this publication, it is difficult to change the feed speed of the rollers during conveyance. Another problem is that oil and liquid adhering to the rollers flow in the axial direction of the rollers and adhere to the bearings, staining the area around the bearings and impairing the rotation of the rollers. There was a problem in that old oil and the like adhering to the rollers adhered to the products being fed by the rollers, deteriorating the quality.

(Means for solving the problem) The present invention was made to solve this problem, and it is a device that transfers fried tofu etc. from an oil pan to a conveyor etc. for the next process. Excess oil can be removed from the lifted items, which improves cooling and oil recovery, prevents oil from sticking, prevents poor feeding, and improves the height of the oil pan and conveyor. The purpose is to provide a roller conveyor that can obtain an appropriate speed regardless of the difference or distance, is easy to disassemble, and can be easily replaced and cleaned. A bearing holder is provided with a number of openings at a predetermined pitch on the upper side and on the side faces facing each other,
Bearings rotatably fixed to both ends of the small-diameter rollers are detachably inserted into the openings of the bearing holder, a large number of small-diameter rollers are arranged in parallel on the frame, and a belt hooking groove is provided at the end of the small-diameter rollers; A small-diameter roller and a drive shaft orthogonal to each other at its end are provided, a number of pulleys are fixed to the drive shaft, and the pulleys and the roller's belt hanging groove are connected and interlocked by a rubber belt, and an oil drain groove is installed at the end of the small-diameter roller. A roller conveyor for conveying fried tofu, etc., which is provided with a small-diameter roller and a thin member for removing oil in contact with the small-diameter roller in the downward longitudinal direction thereof.

(Function) In the roller conveyor of the present invention, a large number of small diameter rollers are arranged in parallel over substantially the entire length of the frame. Furthermore, bearings rotatably fixed to both ends of the small diameter roller are used by being removably inserted into the bearing holding portion.

The small-diameter roller is connected to the drive shaft via a pulley and a rubber belt, so the fried tofu, etc. is conveyed by the rotation of the small-diameter roller. Since a large number of these small diameter rollers are installed in parallel, several small diameter rollers are in contact with the bottom of the fried tofu at the same time, and the driving force is applied to the entire bottom of the frying pan, causing the traveling direction to go out of order or slipping. The fried tofu, etc. is fed without disturbing the entire row, and with oil adhering to the surfaces of the large number of small diameter rollers. At this time, the oil adhering to the small diameter roller immediately moves below the roller, is drained by an oil draining material such as piano wire, and immediately drips downward. This prevents this from adhering to the fried tofu again, improving the cooling effect and oil recovery. Oil won't stick to it. Further, even if oil or the like moves in the axial direction of the roller, the oil cutting groove provided at the end of the roller prevents it from flowing to the bearing, thereby preventing the bearing and its surroundings from becoming contaminated with oil or the like.

Furthermore, when replacing or cleaning rollers and bearings, the rollers and bearings must be removed from the frame. Furthermore, the rotational speed of the roller can be locally changed to an optimum speed by changing the diameter of the pulley.

(Example) Examples of the present invention will be described below based on the drawings.

In this embodiment, a drive shaft that is orthogonal to the small diameter roller and has a connecting part with the roller whose diameter is successively changed is used as a means for driving the small diameter roller, and this drive shaft and a large number of small diameter rollers are connected with a rubber belt. All the small-diameter rollers arranged in parallel on the frame are driven by one axis of the drive shaft, and the rotational speed is varied.
In the example, the receiving side of fried tofu is the slowest,
In addition, the conveyor side of the next process is set to be the fastest, and the speed is changed in four steps in total.

Additionally, oil drains are provided at both ends of the small diameter roller. In this case, since the rotational speed of the roller is variable, no collar is provided and only a groove for draining oil is provided, and a double groove is formed on the side where the rubber belt is connected.

Furthermore, a piano wire is stretched across the axial direction of the lowermost surface of the small-diameter roller and touches it to scrape off oil and residue adhering to the roller surface.

Further, the bearing holding portion provided on the frame is partitioned by an integrally formed partition wall, and one bearing is inserted into each partition from above the frame and held therein. Since this bearing holder is connected to the roller drive means through a rubber belt, there is no need to ensure precision in fitting, and the fitting can be made looser to make it easier to attach and detach the roller, and the structure is simple. Multiple speed adjustments can be made simultaneously on a single axis. In addition, since the load applied to the roller is small, it is sufficient to use bearings at both ends for light loads.For this reason, it is possible to use bearings with an outer diameter that is approximately the same as the outer diameter of the small-diameter roller, so the small-diameter roller is They can be placed side by side almost in contact.

In the figure, 1 is a frame, 2 is a bearing holding part, 3 is a small diameter roller, 4 is a shaft part of the small diameter roller 3, 5 is a belt hanging groove formed in the small diameter roller 3, 6 is an oil drain groove, 7
is a roller bearing as a bearing, 8 is a rubber belt, 9 is a drive shaft, 10 is a first pulley with the smallest diameter,
11 is a second pulley, 12 is a third pulley, and 13 is a fourth pulley with the largest diameter, and the pulley diameter increases from the first pulley 10 to the fourth pulley 13.

Further, 14 is a partition wall, 15 is a piano wire for draining oil, 16 is an oil pan, 17 is a speed adjustable motor, 18 is an endless roller chain, 19 is oil, 20 is a fryer, and 21 is a fryer.

In this embodiment, a belt hooking groove is formed in the small diameter roller 3, and this is connected to the first to fourth pulleys 10, 11, 12, 13 of the drive shaft 9 by the rubber belt 8, so that the rubber belt 8 is not attached to the premises. The small diameter roller 3 can be brought closest to the small diameter roller 3 without being a hindrance. In addition, the speed of each roller can be easily adjusted, and since the shaft support portion of the roller does not require precision machining and installation, it can be manufactured at low cost.

Although the embodiment of the present invention has been described above based on the drawings, the specific configuration of the present invention is not limited to this embodiment.

(Effects of the invention) As described above, according to the invention, oil can be efficiently removed from deep-fried tofu after cooking, resulting in good oil recovery and cooling efficiency. In addition, it is possible to place the product in an orderly manner on the carrier for the next process, and an appropriate speed can be obtained regardless of the difference in height or distance from the oil pan or the carrier.
Moreover, since it is easy to disassemble, parts can be easily replaced and cleaned, allowing you to work efficiently and cleanly at all times.

Furthermore, the oil and liquid adhering to the roller are drained by a thin oil-cutting line that is in contact with the roller and dripped downward, and the oil-cutting groove provided on the roller prevents the oil and liquid from flowing to the bearing. Prevents surrounding dirt and deterioration of roller rotation.
