The chain 11 is driven from the motor 3 installed outside through the speed reduction mechanism 5, the coupling mechanism 4 and the airtight portion 6, and the holding vehicle 8 loaded with the tray 7 is moved so that it can be carried in or out.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tray loading / unloading device of a high temperature / high pressure cooking / sterilizing device (hereinafter referred to as a retort sterilizing device).

[0002]

[Prior art]

 In a conventional retort sterilizer, when loading a holding car loaded with trays containing the items to be sterilized into the sterilizer, place it on the rail provided at the bottom of the sterilizer, slide it in sequence, and push in multiple units. I was there. After carrying out the sterilization process, when the tray was carried out, it was pulled out manually by using a hook rod or a string. Therefore, in a high-temperature and high-pressure retort sterilization device, a device for automatically loading and unloading trays has not been considered.

[0003]

[Problems to be solved by the device]

 Since the holding vehicle with trays loaded as described above is a heavy object, a considerable amount of force was required to manually load and unload the vehicle even if it was slid on the rails. An object of the present invention is to provide a carrying-in / carrying-out device of a retort sterilization device which can carry in and carry out a tray, which is a heavy load, from the sterilization device with one button.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention uses a chain provided along the length direction at the bottom of the retort sterilizer, a shaft for driving the chain, a sprocket and other connecting mechanisms, and a speed reducing mechanism. An external motor that is connected to the sterilizer, an airtight part that is provided between the sterilizer and the outside in the connection mechanism, and a tray that stores the object to be sterilized and loaded along the rail inside the sterilizer. A plurality of holding wheels are provided, a stay is provided in a part of the chain via an attachment, and the holding vehicle that is loaded in the innermost position among the holding vehicles on which the trays are loaded is engaged with the stay. It was used as a tray loading / unloading device of a retort sterilizer equipped with an engaging part.

[0005]

[Action]

 The bottom of the retort sterilizer is equipped with a chain along the length of the retort sterilizer, and the motor as a drive source is installed outside the sterilizer. Since the retort sterilizer has high temperature and high pressure, safety is ensured by providing an airtight part between them. The motor and the chain in the sterilizer are connected by a shaft, a sprocket and other connecting mechanisms, and a speed reduction mechanism, and can be driven with a single button.

A stay is attached to the chain through an attachment, and an engaging portion that engages with the stay is provided on the holding vehicle. Therefore, the stay is engaged with the holding vehicle that is loaded at the innermost position. Then, the plurality of holding wheels are carried inward from the entrance side of the sterilizer according to the driving of the chain, or vice versa.

[0007]

【Example】

 The present invention will be described below with reference to the drawings shown as examples. 1 to 3, reference numeral 1 is a retort sterilizer, which sterilizes food, pharmaceutical products and other sterilized objects under high temperature and high pressure. Reference numeral 2 denotes a chain, which is the bottom of the retort sterilizer 1 and is provided in an oval shape so that it can be reciprocated or rotated. A motor 3 is installed outside the sterilizer. 4 is a connecting mechanism, which is equipped with a shaft, sprockets, chains, bearings, and the like. Reference numeral 5 is a reduction mechanism. Reference numeral 6 denotes an airtight portion, which projects to the side portion of the retort sterilizer 1 and is provided with a shaft support portion, an O-ring, a gasket, and the like. Reference numeral 7 denotes a tray, which stores the objects to be sterilized and is loaded on a holding vehicle 8. The holding vehicle 8 can load and unload trays 7 along rails 9 installed in the length direction.

In FIGS. 3 to 5, reference numeral 10 denotes a stay, which is attached to the chain 2 via an attachment 11 so as to be driven together with the chain 2. Numeral 12 is a rail that guides chain 2. Reference numeral 13 denotes an engaging portion, which is the lower end edge of the holding vehicle 8 which is loaded deepest. The engagement portion is not limited to this portion, and may be provided at any position where it can engage with the stay 10, and the shape thereof is not limited.

In this embodiment, when a plurality of trays 7 are carried in, they are loaded into the sterilization device 1 by sequentially sliding and pushing the holding wheels 8 on the rails 9 while engaging the rails 9. At the time of unloading, by driving the chain 2 by the motor 3, the engaging portion 13 of the holding car 8 is pressed toward the entrance side, and the holding car 8 loaded with a plurality of trays can be simultaneously moved and carried out. I am trying.

In the present embodiment, an example in which the stay 10 and the engaging portion 13 are engaged only at the time of carrying out is shown, but the present invention is not limited to this, and the stay 10 and the engaging portion 13 are engaged at the time of carrying in and carrying out. The transfer by the motor 3 can be enabled. For example, the rotation direction of the chain 2 may be opposite to that in the illustrated example, and the engagement portion 13 may be provided on the back side. In this case, the plurality of holding wheels may be sequentially connected at the entrance side of the sterilizer.

[0011]

[Effect of device]

 In the present invention, by loading a tray containing the sterilized object by operating one button, it becomes possible to carry in or carry out a heavy holding vehicle into or out of the sterilization device as the chain moves, and at the same time high temperature and high pressure are applied. Since the sterilizer and the motor as an external drive source are securely and safely isolated from each other, the operation is convenient and there is no problem in terms of safety.
