Description

Conveyor for plate conveying and dishwasher using the same

The present invention relates to a plate transport conveyor for automatically transporting a standing plate, and a dishwasher including the same.

In general, in various public facilities such as companies, factories, and schools, group catering facilities that provide meals and related services to a large number of people collectively are operated. As the importance of overall aspects of meals such as meal quality, service, and sanitation has been highlighted in these group catering establishments, it is a trend that these tasks are outsourced to an external professional company and managed.

The catering business of the external specialized company has different characteristics from general distribution, and the biggest characteristic of them is in manufacturing and supplying meals for human consumption. Therefore, rather than selling industrial products, it is a place where food that can directly affect the human body is prepared and leftover food is processed, so quality and safety are more important than anything else. Since it is a very important part to be used, it is self-evident that it is necessary to provide safe food, a sanitary place and tableware by frequently checking the sanitary condition of tableware used in common or when cooking food.

However, in the case of tableware, in order to overcome this problem, a large amount of tableware can be washed quickly and hygienically, because in a workplace that has to handle meals for hundreds or even thousands of people, an oversupply phenomenon may occur due to manpower. By having an automatic dishwasher, it is possible to automate the entire process of washing dishes, which used to be done manually, to minimize the manpower and to manage a large amount of tableware more quickly and hygienically.

In the case of dishwashers developed so far, most of the cases are washed while the plates are placed on the conveyor while being transported horizontally. A technique of washing while transporting while standing in a vertical direction is being considered as an alternative. However, in the case of the existing dishwasher technology, which washes dishes while transporting them while standing, in a situation in which the time intervals at which the plates are seated in sequence are different, the intervals between the attachments of the conveyor are the same, so that the plates are stably fixed for all plates. There is a problem in that it is difficult to transport, and also has an irregular directionality when the plate is dropped and seated, so it is difficult to stably accommodate and transport the plate.

The present invention was derived to solve the above problems, stably accommodating the plate that is seated at irregular time intervals, and falls in an irregular direction, while stably accommodating the plate so that the plate does not slide in the direction opposite to the transport direction of the plate. An object of the present invention is to provide a conveyor for transferring a plate that can be transferred.

In the present invention, in order to enable interaction between the anti-skid part and the stopper with a simple structure in the transport situation of the plate, the attachment part is preferably integrally formed with the anti-skid part at a predetermined inclination with the stopper. . This is because in a situation where the plate is not seated, the stopper rotates until the stopper is caught by the adjacent support rod and no longer rotates because the weight of the stopper is greater than that of the anti-skid part, and at this time, while forming an inclination with the stopper The integrally formed anti-skid portion is maintained while being lifted upward as much as the stopper rotates.

On the other hand, in a situation in which the plate is seated, the attachment part located within the seating range of the plate is pressed down by the weight of the seated plate until the anti-skid part crosses the adjacent support rod part, and the anti-skid part and The stopper integrally formed with an inclination is lifted and separated from the supporting rod over which the plate is placed, and the attachment part located outside the seating range of the plate is in contact with the side end of the plate while the anti-skid part is lifted, and the anti-skid Since the stopper formed integrally is placed in a state in which rotation is impossible because the stopper is caught on the adjacent support rod, it is possible to suppress the plate from being pushed in the opposite direction to the conveying direction.

Since the rod part is hollow in the attachment part, the fastening part is inserted through and serves as a rotation axis of the attachment part and at the same time serves to enable the attachment part to be fastened with the link part, and the present invention is not particularly limited, but a plate In order to enable interaction between the anti-skid part and the stopper with a simple structure in the transport situation of

In the attachment part, the anti-skid part is formed with a shock absorbing layer that absorbs the impact applied when the plate is seated in order to minimize the damage of the anti-skid part or the plate due to the accumulation of shocks due to the continuous seating of the plate. The material of the shock absorbing layer may be any material capable of absorbing or dispersing the shock applied while the plate is descending, for example, it may be a foamable resin material or an elastic material such as rubber.

On the other hand, the stopper stably guides and accommodates the plate to be seated by falling in an irregular direction in a wide range, and a pair of wings protruding symmetrically in the vertical direction in a spaced state to minimize the separation of the plate is formed. may be desirable.

In addition, in order to prevent the plate being transported from being pushed in the opposite direction to the transport direction, and to minimize the plate separation while accommodating the plate widely, it may be preferable that a groove is formed in the portion in contact with the plate. . For example, the groove may be a 'U'-shaped groove.

Another aspect of the present invention relates to a dishwasher, characterized in that it uses the conveyor for transferring the plate, and more specifically, a tableware and plate input unit for separating the tableware and the plate while transporting the plate including the dishes placed sequentially. ; a plate transport unit for transporting the plate discharged from the tableware and plate input unit; a plate washing unit for washing the plate transferred through the plate transport unit; and a plate discharging unit for discharging the plate after washing by the plate washing unit, wherein the plate transport unit includes: a first transport unit for transporting the plate while being placed horizontally or inclined; a plate conversion unit that rotates the plate being transported horizontally or obliquely from the first transport unit and erects in a vertical direction; In the plate conversion unit, the plate is transferred while standing in the vertical direction in the vertical direction, but a second transfer unit for transferring using the conveyor for transferring the plate; includes, wherein the plate conversion unit is outside the end of the first transfer unit It is characterized in that it comprises a rotation inducing member in the form of a curved surface for guiding one end of the rotating plate to be seated on the conveyor of the second transfer unit.

In the present invention, the tableware and plate input unit separates the tableware and the plate while transferring the plate containing the sequentially placed dishes. The dishwasher according to the present invention separates and washes the tableware and the plate, so that the plate including the tableware It is important to separate the plate from the tableware in the step of putting it into the automated washing system. The tableware and plate input unit of the present invention comprises: an input conveyor for transporting a plate containing horizontally placed dishes; and an inclined separating unit that separates the dishes from the plate while the plate including the transported plate is tilted because the surface of one region in the vertical direction to the transporting direction of the plate including the plate is an inclined plane on which a roller is formed; It is preferable to include

It is preferable that the input conveyor unit has a lifting prevention member for preventing the plate from being lifted by hooking at least one end of the plate being transported at both ends in a direction perpendicular to the direction in which the plate containing the tableware is transported. The anti-lift member may be, for example, a pair of symmetrical 'L'-shaped structures. Furthermore, it may be more preferable that the anti-lift member has a dish guide member that serves to gather the dishes on the plate being transferred to a specific part on the plate in one region of the upper surface. This is because when the plate is tilted in either direction while passing through the inclination separator, if the dishes placed on the plate are concentrated on the side of the plate in the inclined direction, the plate is tilted more smoothly and the plate is separated from the plate well. , this is because it is possible to prevent dishes from being thrown out in an unintended direction as the plate is tilted.

On the other hand, it may be preferable that a roller unit rotating with its own power is provided between the input conveyor unit and the inclination separation unit. This is because the power transmitted from the input conveyor to the plate becomes weaker and weaker at the part where the plate on which the dishes are placed passes from the input conveyor to the incline part, and this compensates for this. in order to be able to Furthermore, it is more preferable that the roller part is a two-stage roller part having a structure in which two rollers are positioned side by side and rotate in the same direction so that the plate on which the dishes are placed can pass more smoothly and smoothly from the input conveyor part to the inclined separator part can

In addition, in order to prevent the plate from causing a malfunction due to the dish and the inner part of the plate input unit being caught in the direction of the inclined plate being severely misaligned, the inclined separating part is formed to protrude on the surface of the other side area which is a horizontal plane and is made of a rotating ball bearing. It is preferable that the ball bearing part is formed. The ball bearing unit may be composed of one or two or more ball bearings, and when it is composed of a plurality of ball bearings, it is preferable to have a structure in which the ball bearings are arranged in series along the direction in which the plate is transported in terms of preventing distortion of the plate. can

In the present invention, the plate transport unit transports the plate discharged from the tableware and plate input unit, and the plate transport unit of the present invention washes the plate placed horizontally or obliquely in the vertical direction while the plate is transported to the plate washing part.

In particular, in the present invention, the plate conversion unit comprises a curved rotation inducing member for guiding one end of the plate rotating while leaving the end of the first transfer unit to be seated on the conveyor of the second transfer unit. According to the present invention, by using a curved rotation inducing member to vertically erect a horizontally placed plate in the plate conversion unit, a large amount of plate can be sequentially erected with a simple structure without additional power. The rotation inducing member faces the first transfer unit, but is spaced apart from the end of the first transfer unit at a predetermined interval, and it is preferable to have a convex curved surface shape away from the first transfer unit for smooth vertical transformation of the plate. .

It may be preferable that the second transfer unit be provided with a plate support rod part comprising two rows of array guides spaced apart from each other to support the vertically erected plate to maintain the erected state during transport.

Furthermore, it is more preferable that the plate support rod part is inclined so that the guide positioned closer to the first transfer part among the rods of the two-row arrangement extends into the plate conversion part, and the distance from the rotation inducing member is gradually widened. can This is to prevent the occurrence of a phenomenon in which a large number of plates are sequentially rotated through the rotation inducing member, and the end of the plate is stamped on the surface of the rotation inducing member in the middle, thereby causing the plate to be jammed.

In the present invention, the plate washing unit washes while transporting the plate transferred through the plate transport unit, and the washing, rinsing, and drying processes of the plate are sequentially performed in the plate washing unit. The plate washing unit may have a structure in which the plate is washed while being transported in a horizontal state, or may have a structure in which the plate is washed while transported in a vertical state. .

In the present invention, the plate discharging unit discharges the plates washed by the plate washing unit, and the washing-finished plates sequentially discharged through the plate discharging unit are loaded into the plate loading cart and managed separately.

According to the conveyor for transferring the plate according to the present invention, the plate is arranged at irregular intervals, and the plate is stably accommodated while falling in an irregular direction, and the plate is transported while standing so that the plate is not pushed in the opposite direction to the transport direction of the plate.
