Description

[Detailed description of the invention] <<Purpose of the invention>><Industrial application field> The present invention is a method for maintaining the transfer posture of a lunch box, which is an object to be processed, in a predetermined state in a cleaning device for lunch boxes, etc. It concerns the configuration mechanism.

<Background of the invention> The applicant has developed a device that automatically cleans lunch boxes, etc. for catering, and has already developed a device for cleaning lunch boxes, etc.
(Patent Application No. 61-261491). As schematically shown in Fig. 6, the object to be processed A, such as a lunch box, is placed on a supply conveyor 4' constituting a conveyance zone with its open side facing upward, and the object to be processed is allowed to fall freely in a reversing zone. The body A, such as a lunch box, is inverted and dropped so that the open side faces downward, then slid downward in the chute zone, and further transferred to the cleaning conveyor 8' while remaining face down in the transfer zone.
Next, in the cleaning zone constituted by the cleaning conveyor 8', the cleaning liquid L is sprayed onto the object to be processed A, such as a lunch box, to clean the inside thereof, and then the object is taken out from the take-out zone.

By the way, the object to be processed A, such as a lunch box, has its shape,
In the case of a heat-retaining type lunch box, which has a wide variety of weights, even with the above-mentioned prior art, there have been rare cases in which the desired state of operation in the transfer zone cannot be obtained. In other words, as soon as the relatively heavy lunch box leaves the sliding section 6 that forms the lower side of the reversing guide chute 5', which is a supporting member, in the transfer zone, the tip of the box drops, and only the tip of the box moves to the washing conveyor below. 8', is pushed into the transfer locking protrusion 10' there, and is pushed back as it is.
As a result, there are rare cases where the cleaning conveyor 8' gets caught between the tip of the sliding section or a member near it, and smooth transfer is not possible, and there is still room for improvement in this respect.

<Technical matters attempted to be solved> The present invention was made in an attempt to solve the technical problems in the prior art, and it is designed to ensure that all kinds of bento boxes can be delivered in the transfer zone. This was an attempt to develop an improved mechanism to do so.

《Structure of the invention》 〈Means for achieving the purpose〉 That is, the transfer posture setting mechanism of the cleaning device for lunch boxes, etc., according to the present invention, is arranged so that the transfer position setting mechanism of the present invention is arranged so that the transfer position setting mechanism in the cleaning device for lunch boxes, etc. is provided with a nozzle for position setting, and this nozzle is configured to inject a fluid toward the lower surface of the object to be processed, and the jet of this fluid also removes the object that is about to come off the support member. This is characterized by the fact that the vehicle travels while maintaining almost the same vertical position, thereby achieving the above-mentioned object.

<Operation of the invention> In the present invention, the object to be processed is transported in a sliding state by the support member disposed in a downwardly facing state. When the object to be processed begins to come off the tip of the support member, fluid is ejected from the nozzle downwards on the object to be processed, and the object to be processed maintains its vertical posture as if it were supported by the fluid. It is sent out from the support member as it is.

<Example> The present invention will be specifically described below based on the illustrated example. First, a prior art cleaning device for lunch boxes and the like to which the present invention is applied will be briefly explained. As already mentioned, this cleaning device 1 was developed by the applicant, and the cleaning chamber 3 is divided into a frame 2 which is formed in the shape of a rectangular parallelepiped. It incorporates various mechanisms that perform cleaning functions and the like. Reference numeral 4 denotes a supply conveyor, which supplies objects to be processed A, such as lunch boxes, into the cleaning apparatus 1 from the outside, and substantially forms a conveyance zone. It should be noted that the object to be processed A, such as a lunch box, is placed on the supply conveyor 4 with its open end facing upward and transferred. This supply conveyor 4
A reversing guide chute 5 is formed at the leading end of the feed conveyor 4, and the space between the leading end of the supply conveyor 4 and the reversing guide chute 5 substantially constitutes a reversing zone. Further, the reversing guide chute 5 has a substantially linear downwardly inclined sliding portion 6 at its lower side, and this sliding portion 6 substantially constitutes a chute zone. In particular, the sliding portion 6 of this reversing guide chute 5 is for guiding the object A to be processed substantially in a sliding state, and is one of the embodiments of the support member defined in the claims of the utility model registration. A stopper 7 is provided in front of the shoot zone.
will be established. Further, there is provided a cleaning conveyor 8 whose transport track is substantially starting from below the stopper 7. For example, this cleaning conveyor 8 has a transport track which is inclined so that the side to be transported faces upward. It consists of The tip of the sliding section 6, the stopper 7, and the vicinity of the starting point of the transfer trajectory of the cleaning conveyor 8 substantially become a transfer zone. The conveying action of the cleaning conveyor 8 is directly performed by a large number of link pieces 9 that constitute the cleaning conveyor 8, and a part of the link pieces 9 is provided with objects to be processed A such as lunch boxes at regular intervals. A locking protrusion 10 is provided to ensure the transfer of the material. The range up to the terminal end of the transport track of the cleaning conveyor 8 is defined as a cleaning zone, and a take-out chute 11 is provided following this, and substantially constitutes a take-out zone.
Incidentally, in the cleaning conveyor 8, cleaning part water sprinkling pipes 12a, which constitute a part of the water sprinkling pipe 12, are provided above and below, and the cleaning liquid L is spouted onto the object to be processed A, such as a lunch box, on the cleaning conveyor 8. It is used for cleaning.

The cleaning device 1 to which the present invention is applied includes the main components as described above, and the present invention is applied to a transfer zone in the cleaning device 1 as an example. This part will be explained below. Code 12b
is a posture setting nozzle which is one of the characteristic configurations of the present invention, and has almost the same mechanism as the water spray pipe 12 described above, and is supplied with a portion of the cleaning liquid L from the same supply source as an example. Configure it so that Specifically, a large number of pores are formed in a tubular member, and the direction of jetting the cleaning liquid L from this nozzle 12b is set to be approximately horizontally forward in the figure or to a slightly upward position. As an example, the stopper 7 provided in the front has a horizontal V.
It consists of a plate-like member formed in a letter shape, with its upper surface serving as an upper surface plate 13 and its lower surface serving as a mounting plate 14. This upper surface plate 13 is stretched in a substantially horizontal direction, and the mounting plate 14 is arranged so that the object to be processed A, such as a lunch box, etc., is slid from the sliding section 6 in a direction in which it is returned. Take shape. In this embodiment, the entire stopper 7 is made of a transparent synthetic resin material, and in this case, the transfer zone where the most trouble is expected can be seen from the outside, and inspection and maintenance work can be easily carried out. obtain. Furthermore, in this embodiment, the stopper 7 itself is configured to be removable for ease of inspection, etc. Specifically, a latching protrusion 16 is provided on the side plate 15 of the stopper 7, and correspondingly, a set hook 17 is provided on the frame 2 side, and these are simply latched to the stopper 7. This made it possible to install it. Of course, the stopper 7 may be a member that simply stops the movement of the object A by coming into contact with the tip of the object A that slides from the sliding section 6 while maintaining almost the same posture, or it may be a member that stops the movement of the object A, or it may be a member that stops the movement of the object A that slides from the sliding section 6 while maintaining almost the same posture. Although the shape is similar to that of the embodiment of the stopper 7 described above, for example, several steel rods may be arranged in a fence shape, and this may be further covered with a panel board etc. that can be viewed from the outside. Of course, there is no problem.

The present invention has the specific configuration as described above, and operates as follows. First, when the object A to be processed, such as a lunch box, sent into the cleaning device 1 is placed face down in the reversal zone and slides through the chute zone, the support member constituting the tip side of the reversal guide chute 5 slides. Part 6
The state is such that the object to be processed A, such as a lunch box, comes off from the lower tip. At this time, the cleaning liquid L is vigorously jetted from the nozzle 12b, and due to the direction of the jetting, the cleaning liquid L is sprayed from the bottom to the top of the object to be treated A, such as a lunch box. As a result, the object to be processed A, such as a lunch box, which is almost no longer supported by the sliding portion 6, is supported instead, and the object is brought to the stopper 7 while maintaining almost the same vertical posture. Of course, if the spraying state of the cleaning liquid L from the nozzle 12b is extremely strong, the object A to be treated, such as a lunch box, will come into contact with the top plate 13 of the stopper 7, and the residue inside it will also be removed. There is some exclusion here. When the object to be processed A, such as a lunch box, comes into contact with the innermost part of the stopper 7, the nozzle 12b
Since the action of the cleaning liquid L from the cleaning liquid L weakens, the object to be processed A, such as a lunch box, falls directly onto the mounting plate 14 forming the lower surface of the stopper 7, and then runs facing near the tip of the lower surface of the mounting plate 14. For example, the object to be processed A, such as a lunch box, is hooked from the inside of the object to be processed A, such as a lunch box, and transferred.
The cleaning action takes place in the subsequent cleaning zone.

The present invention has the above-mentioned configuration, and basically, even if the object to be processed A, such as a lunch box, is transported by a chute or a conveyor, etc., and the supporting state of the object is released at its tip, This mechanism can be applied to cases where the posture is to be maintained somewhat as it is, and this mechanism is not limited to being applied to the cleaning apparatus for lunch boxes and the like mentioned above. In addition, nozzle 1 is directly responsible for attitude control.
The cleaning liquid L sprayed from 2b may be any fluid as long as it is an air flow or other gas flow.

<<Effects of the invention>> The present invention has the above-described configuration, and even when the object to be processed A, such as a lunch box, is about to come off the sliding part, which is an example of a supporting member, while being transferred, Since it is supported by a separate fluid for a certain period of time, it is possible to prepare for the next transfer or operation while maintaining its vertical transfer posture for a while, and a reliable transfer form can be obtained. Furthermore, the transfer at this time is sliding transfer using a supporting member, and this structure is simple and the occurrence of failures can be minimized.
