Description

[Detailed description of the invention] [Field of application of the invention] This invention applies temperature stress to products and parts in order to eliminate initial defects in the products and parts, and eliminates those that break due to this heating. This relates to the aging bath (constant temperature bath) used for this purpose.

[Background of the idea]

The conventional structure of this type of aging tank is as follows:
For example, there is one shown in FIG. This aging tank A with a conventional structure has double doors B and C for taking products and parts (hereinafter referred to as aging parts) in and out, and behind these double doors B and C, There are three component mounting tables D arranged in the upper and lower tiers, and a plurality of aging components can be placed on each of the component mounting tables D. E is a constant voltage power supply operation panel installed at the lower front of aging tank A, F is a control panel, and G is a power supply cord. Aging tank A with these structures is a well-known commercially available Since this is just a structure, detailed explanation will be omitted.

During aging processing using the aging tank A having such a structure, first, double doors B and C are fully opened and a predetermined number of parts to be aged prepared in advance are placed on each mounting table D. Since 4 parts to be aged can be placed on each stage, 4 parts x 3 stages = 12 parts to be aged can be stored. In this way, when the storage of the parts to be aged in the aging tank A is completed, the double doors B and C are closed, and then the power operation panel E and the control panel F are operated for a predetermined period of time (for example, 90 minutes). Start aging. After a predetermined period of time has elapsed, doors B and C are opened, all aged parts in aging tank A are taken out, replaced with new aged parts that are on standby, and the same operation as above is repeated. .

However, because such conventional aging tanks have a batch processing structure, it is necessary to open both doors each time a part to be aged is taken in or taken out, which results in the accumulation of waste inside the aging tank. Thermal energy is wasted because all of it is exhausted. Moreover, the time required to raise the inside of the aging tank A to a predetermined temperature again becomes long, resulting in problems such as a decrease in aging treatment efficiency.

[Purpose of invention]

The present invention was made to solve the problems of the conventional aging tank.The aging tank is provided with a plurality of pallets that can be pulled out individually, and any one of the pallets can be selectively taken out and put in to remove the aging tank. The purpose of the present invention is to provide an aging tank that can suppress the amount of thermal energy discharged in the aging tank by replacing parts, thereby saving labor on thermal energy and increasing the efficiency of aging processing. It is something.

[Example of idea]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 6.

Reference numeral 1 denotes an aging tank main body, and on the front side of this aging tank main body 1, a total of 12 drawer means 2 in 4 vertical stages and 3 horizontal rows are provided so as to be removable. The container is configured such that a single aging component (not shown) can be placed and stored therein. As shown in FIGS. 2 and 3, the detailed structure of this pull-out means 2 includes a pallet 201 on which parts to be aged are placed. This pallet portion 201 has high air permeability,
Moreover, the entire network is formed with sufficient strength to withstand the weight of the parts to be aged. Also, this palette part 2
At the front end of the aging tank body 1, there is a front cover 2 which is formed to be slightly larger than the shape of the drawer opening 101 of the drawer means 2 provided on the front surface of the aging tank main body 1, and which can close the drawer opening 101 when the drawer means 2 is pushed in.
02, and at the rear end of the pallet portion 201 is provided a rear lid 203 having the same shape as the front lid 202 and capable of closing the drawer opening 101 when the drawer means 2 is pulled out. 204

206 are integrally formed on both side edges of the pallet portion 201. As shown in FIG. The rail 206, which has a U-shaped cross section, is guided by rollers 207 installed in the aging tank main body 1, and supports the drawer means 2 so as to be freely inserted and removed. Reference numeral 208 denotes a connector attached to the pallet portion 201 for supplying power to electrical components provided in the drawer means 2, and this connector 208 is connected to a power connection plug (not shown) via a cable 209. This is what is being done. Since this cable 209 must expand and contract following the insertion and removal of the pull-out means 2, this cable 209 is connected to a horizontally extendable pantograph type flexible arm 210 installed in the front and back direction of the aging tank main body 1.
The cable 209 is suspended to prevent the cable 209 from coming into contact with other objects and being pulled when the pull-out means 2 is pulled out or pushed in, or to prevent abnormal tension from acting on it. In addition, as another embodiment instead of the above-mentioned flexible arm 210, the sixth
As shown in the figure, an extendable pantograph type flexible arm 210' may be provided vertically in the front-rear direction of the aging tank main body 1, and the cable 209 may be suspended from this pantograph type flexible arm 210'.
A detection switch 211 is attached to the pallet section 201 and detects whether or not a part to be aged is placed on the pallet section 201. A detection switch 212 is attached to the front cover 202 to detect whether or not a part to be aged is placed on the pallet section 201. This is a limit switch that detects whether it is pulled out or pushed in.

Although the structure of the drawer means 2 and its surroundings has been described above, a constant voltage power supply panel 4 and a control device panel 5 are provided at the upper front of the aging tank main body 1. 6

The above is the structure of this embodiment.Next, its operation will be described.First, the heater 8 and motor 6 are operated to maintain the inside of the aging tank 1 at a predetermined heating temperature, and then the supply is sequentially supplied from the production line. A worker sequentially places and accommodates each aged part on the pallet of each drawn-out means 2, and aging is carried out. In order to set one of the drawer means 2, the rear cover 203 of the drawer means is attached to the aging tank main body 1.
Pull it out to a position where it closes the opening 101. This allows heated air in the aging tank 1 to flow through the opening 1.
Aging tank body 1 without being discharged from 01
This prevents wasteful exhaustion of thermal energy inside. The pallet portion 201 of the pull-out means 2 thus pulled out
When a part to be aged is placed on top of the switch 21
1 works. After the parts to be aged are placed on this pallet section 201, when the pull-out means 2 is pushed into the aging tank 1, the switch 212 is operated and a signal is output from the AND circuit 216 in cooperation with the switch 211 described above. Te timer 217
aging starts as soon as it operates. When the set time is reached, the transistor 220 is turned on and the display 205a is lit to indicate that the aging of the aging component has been completed. Each part to be aged is placed and accommodated on the drawer means 2. The display device 205a lights up in the order of the drawer means 2 in which the parts to be aged are set first, to notify that the aging process for a predetermined period of time (90 minutes in this embodiment) has elapsed. Drawer means 2 with indicator 205a lit
When the switch 212 is pulled out, the switch 212 is activated, thereby resetting the timer 217. Next, when the parts on the pull-out means 2 that have been aged are picked up by the pallet 201, the switch 211 is operated, and the output of the inverter 219 becomes high level, which turns on the transistor 221 and makes the part on the pallet 201 empty. The display 205b indicates that this has become the case. Next, a new part to be aged is placed on the now empty drawer means 2, and the puller means 2 is pushed in again to continue the aging process in the same manner as described above.
Thereafter, by sequentially replacing the aged parts in each drawer means 2 with new parts,
Continuously aging parts are obtained one after another.

In this way, by using the aging tank according to the present embodiment, it is possible to sequentially pull out each of the 12 drawer means 2, take out aged parts that have undergone aging, and replace the storage with new aged parts. Therefore, during the rotation of each pull-out means, the parts to be aged can be processed one after another without being delayed in the transfer process, and the aging process can be completed in connection with this. Since processed parts can be obtained continuously, aging can be performed with high production efficiency.

In addition, when all the drawer means 2 are pushed into the aging tank main body 1, the front cover 20
Since the opening 101 is closed by the opening 101, the hot air inside the aging tank body 1 is not leaked (discharged). Since the opening 101 is temporarily closed, the hot air inside the aging tank main body 1 is not leaked, and therefore it is possible to save the thermal energy inside the aging tank main body 1, and the inside of the aging tank main body 1 can be saved. The internal temperature of the aging tank body can be stabilized by keeping the temperature substantially constant at all times, which also has the effect of improving the quality and processing efficiency of the aging process. Further, according to this embodiment, a guide rod 210 or a pantograph-type flexible arm 210' is provided inside the aging tank main body 1 in the front-rear direction, and a cable connected to the guide rod or arm to the pull-out means 2 is provided. Since the cable 209 is suspended, there is no risk that the cable 209 may come into contact with or interfere with other objects and cause damage due to abrasion or the like when the pull-out means 2 is pulled out or pushed in, or that the cable 209 gets in the way. This has the effect of eliminating problems that may occur and maintaining a safe and stable cable arrangement.

Furthermore, according to this embodiment, each of the drawer means 2 is provided with an empty indicator 205b that indicates that no component is placed, and an indicator 2 that lights up when the aging processing time for the aging target member reaches a predetermined time.
05a, the presence or absence of the aging member in the pull-out means 2 and the completion state of aging can be visually recognized very easily, which also has the effect of increasing the efficiency of the aging process.
