<Elevating device 3>
The lifting / lowering device 3 shown in FIGS. 1 and 2 includes a filter unit that removes invisible hazard substances such as powder and gas adhering to the processing object M. In other words, the lifting device 3 is an example of a filter unit mounting type delivery unit. The position of the lifting / lowering device 3 can be moved by using a movable caster 2T and can be positioned.

  Particularly preferably, the lifting device 3 is equipped with a HEPA filter unit 14 in order to remove invisible hazard substances such as powder and gas adhering to the processing object M. The lifting device 3 is disposed between the vacuum constant temperature dryer 2 and the enclosure 4.

  FIG. 6 is a side view showing the structure of the lifting device 3. FIG. 7 is a diagram illustrating a structure example of the lifting platform 11 of the lifting device 3. FIG. 8 is a front view showing the structure of the lifting device 3. FIG. 9 is a plan view showing the structure of the lifting device 3.

  The lifting device 3 shown in FIGS. 1, 2 and 6 to 9 is made of a heat-resistant metal, such as stainless steel. As shown in FIGS. 1 and 6, the lifting device 3 includes a base 10, a rectangular lifting platform 11, an lifting actuator 12, and preferably a HEPA filter unit 14 that is a filter unit.

  As shown in FIGS. 2 and 6, the base 10 supports the lifting platform 11 and accommodates the HEPA filter unit 14. The base 10 is rectangular and has a box shape so as to be long along the Y direction. The base 10 has a region 10A that supports the lifting platform 11 and a region 10B that protrudes from the lifting platform 11 in the Y direction and accommodates the HEPA filter unit 14.

  The elevator 11 shown in FIGS. 1 and 2 is made of a particularly heat-resistant metal such as steel. As shown in FIG. 7, the lifting platform 11 is a rectangular hollow member, for example. As shown in FIGS. 1, 2, and 7, a work surface portion 13 that forms a work surface is detachably disposed on an upper surface portion of the lifting platform 11. The work surface portion 13 is preferably a heat-resistant, for example, stainless punched rectangular plate member.

  As shown in FIGS. 2 and 7, the work surface portion 13 is preferably formed with a plurality of holes 13H, for example, over the entire surface. Since the work surface part 13 can be removed from the elevator 11 as necessary, maintenance work such as cleaning when the hole 13H of the work surface part 13 is clogged can be facilitated.

  Thus, when the processing object M vacuum-heated in the vacuum constant temperature dryer 2 is placed on the work surface part 13 of the lifting platform 11 during delivery, the work surface part 13 becomes heated. The heat generated is dissipated through the plurality of holes 13H. In addition, as illustrated in FIG. 7, the work surface portion 13 allows the air DR including a hazard substance such as powder of the processing object M to pass through the plurality of holes 13 </ b> H into the space 11 </ b> S of the lifting platform 11.

  As shown in FIGS. 6 and 8, a fixed plate portion 85 is horizontally fixed on the region 10 </ b> A of the base portion 10. The lower part of the elevator 11 is fixed to the upper part of the support member 87. The lower part of the support member 87 is fixed on the movable plate part 86.

  The movable plate portion 86 is arranged in parallel with the upper portion of the fixed plate portion 85, and the movable plate portion 86 and the fixed plate portion 85 are connected by left and right link portions 80 and 80 as shown in FIG. An intermediate portion between the first link member 81 and the second link member 82 of each link portion 80 is connected by a connecting member 83. Thereby, the movable plate part 86 and the lifting platform 11 are movable along the Z direction with respect to the fixed plate part 85.

  As shown in FIGS. 2 and 8, the end of the main body of the lifting actuator 12 is attached to the fixing plate 85 on the region 10 </ b> A side of the base 10 using, for example, a pin. As shown in FIG. 8, the telescopic rod 12 </ b> R of the lifting / lowering actuator 12 is attached to the movable plate 86 at the lower part of the lifting / lowering base 11 using, for example, a pin. As the lifting / lowering actuator 12, for example, a hydraulic cylinder, a pneumatic cylinder or an electric cylinder can be adopted. Alternatively, the lifting / lowering actuator 12 may be a linear actuator including a motor and a feed screw connected to the output shaft of the motor.

  The elevator actuator 12 shown in FIG. 8 is moved to the upper limit position by a predetermined stroke ST along the Z direction on the work surface portion 13 of the elevator base 11 shown in FIG. The work surface part 13 of the lifting platform 11 is moved up and down between the UL and the lower limit position LL. Thereby, the work surface part 13 of the lifting platform 11 can be positioned at a plurality of height positions between the strokes ST.

  Preferably, the height position in the Z direction of the upper limit position UL shown in FIGS. 1 and 6 corresponds to the position of the uppermost shelf in the region of the vacuum heat treatment space SR of the vacuum constant temperature dryer 2. Further, the height position in the Z direction of the lower limit position LL is set in accordance with the position of the opening 20 for insertion of the enclosure 4 to be described next. For example, the elevator 11 has a plurality of height positions between the upper limit position UL and the lower limit position LL in accordance with the positions of the plurality of shelves arranged in the vacuum heat treatment space SR of the vacuum constant temperature dryer 2. In FIG.

  Thereby, the operator opens the open / close door 2B of the vacuum constant temperature dryer 2 shown in FIG. 1, takes out the processing object M from the shelf board in the vacuum heating processing space SR, and quickly places it on the lifting platform 11. Then, the processing object M can be quickly transferred from the elevator 11 to the working space G in the enclosure 4 through the opening 20 of the enclosure 4 and delivered. For this reason, the delivery work of the processing object M can be easily and safely performed by using the lifting device 3.

  Further, as described above, a plurality of elevators 11 are provided between the upper limit position UL and the lower limit position LL in accordance with the positions of the plurality of shelves arranged in the vacuum heat treatment space SR of the vacuum constant temperature dryer 2. Can be positioned at each of the height positions. For this reason, for example, when the unprocessed or semi-dried processing object M is put into the vacuum heat treatment space SR of the vacuum constant temperature dryer 2 and is to be dried, this processing placed on the lifting platform 11 is performed. The object M can be easily put and placed on each shelf board arranged in the vacuum heat treatment space SR of the vacuum constant temperature dryer 2.

  As shown in FIGS. 6 and 8, the arrangement position of the HEPA filter unit 14 is arranged in the base 10 at a position different from the arrangement position of the lifting platform 11, that is, a position shifted in the Y direction. That is, the HEPA filter unit 14 is disposed not in the area 10 </ b> A of the base 10 but in the area 10 </ b> B of the base 10.

  An example of the structure of the HEPA filter unit 14 is shown in FIGS. As shown in FIGS. 6 and 9, the filter unit 14 is a fan filter unit with a built-in HEPA composed of a filter 15 and a blower fan 16, and is an apparatus with an indoor open type silencer. The filter 15 can be replaced as necessary.

  As the filter 15, it is preferable to use a HEPA filter that is a high-performance filter used in a field where air purification is required, for example, as an exhaust filter. However, as the filter 15, in addition to the HEPA filter, an adsorbent filter using an adsorbent such as activated carbon can be used, but is not particularly limited.

  As shown in FIGS. 6 and 9, the position of the lifting platform 11 and the position of the filter unit 14 are shifted with respect to the Y direction. Moreover, the elevator 11 moves up and down in the Z direction. Therefore, in order to connect the lifting platform 11 and the filter unit 14 at different positions by a connection tube, the lifting platform 11 and the filter unit 14 are connected by a flexible tube 17 as a telescopic connection tube.

  As shown in FIG. 7, one end 17 </ b> A of the flexible tube 17 is detachably attached to the connection port 11 </ b> P of the lifting platform 11. The connection port 11P is connected to the space 11S of the lifting platform 11. As shown in FIGS. 6 and 9, the other end 17 </ b> B of the flexible tube 17 is detachably attached to the connection port 14 </ b> P of the filter unit 14. This connection port 14 </ b> P is located in the upper part of the blower fan 16 of the filter unit 14.

  As described above, the elevator base 11 and the filter unit 14 are connected by the flexible tube 17 as an extendable connecting pipe, so that the flexible tube 17 can be moved even when the elevator base 11 moves up and down as shown in FIG. Is able to reliably maintain the connection state by elastically deforming the lifting platform 11 and the filter unit 14 while following the lifting operation of the lifting platform 11.

  As illustrated in FIGS. 8 and 9, in the filter unit 14, the blower fan 16 is disposed on the upstream side of the filter 15. On the downstream side of the filter 15, a lower exhaust part 19 is arranged as an air discharge part. The lower exhaust part 19 is also referred to as a lower exhaust slit part.

  When the blower fan 16 of the filter unit 14 is driven, as shown in FIG. 7, the air DR including the hazard substance such as powder from the processing object M passes through the hole 13 </ b> H of the work surface portion 13 and the lift 11 By passing through the flexible tube 17 shown in FIG. 6 through the space 11S, it is sent to the filter unit 14 side.

  Thereby, in FIG. 8, hazard substances, such as powder, are captured by the filter 15 of this filter unit 14, and the air N becomes clean. The cleaned air N can be discharged to the outside through the lower exhaust part 17 from the exhaust opening 201 which is a slit.

  The filter 15 such as the HEPA filter after use shown in FIGS. 5 and 6 is put in, for example, a storage bag, and more preferably in the collection bag, the filter 15 is put together with the storage bag. The filter 15 can be removed while being wrapped. Thereby, when the processing object M is moved from the vacuum constant temperature dryer 2 into the enclosure 4, it is possible to prevent the hazard substance such as powder from scattering from the used filter 15.

  By the way, the vacuum constant temperature dryer 2 rotates the blower fan 16 of the filter unit 14 of the lifting / lowering device 3 described above in the vacuum heat treatment space SR in the tank when opening and closing the door 2B. Can be exhausted. Thereby, the powder in the vacuum heat treatment space SR of the vacuum constant temperature dryer 2 is not scattered outside the vacuum constant temperature dryer 2.

<Enclosure 4>
The enclosure 4 shown in FIGS. 1 and 2 is arranged on the left side of the lifting device 3.

  As described above, the enclosure 4 preferably contains the processing object M that has been subjected to the vacuum heat treatment and a target device for processing the processing target M in the work space G, and uses this device. Then, a predetermined processing operation is performed. As this predetermined processing operation, for example, the processing object M such as a crystal sample is weighed with a balance, and the processing object M is subdivided.

  The enclosure 4 is preferably a low airflow draft chamber that allows air to pass through with a low airflow draft when the operator performs the required work using the device M in the work space G in the warehouse. As described above, this work is a process in which the amount of the dried processing object M such as a crystal sample is weighed and subdivided using a balance, but is not particularly limited.

  In recent years, the enclosure 4 is required to be able to operate with an exhaust air volume smaller than a conventional air volume from the viewpoint of energy saving. As the enclosure 4, for example, a constant air volume type in which the exhaust air volume is always constant (CAV: constant air volume control) can be adopted. However, the enclosure 4 is not limited to this, and from the viewpoint of further energy saving, a variable airflow type that combines a VAV (variable airflow control) method with this constant airflow type may be used.

  The enclosure 4 isolates the atmosphere of the internal working space G from the outside so that the worker is not affected by the processed material or harmful substances when processing the processed material in work or experiments in the internal working space. It has the structure to do. The enclosure 4 is a local exhaust device for the purpose of protecting workers, and has an enclosed work space G having a function of containing dangerous substances and harmful substances and an exhaust function.

  As shown in FIGS. 1 and 2, the case portion 31 includes a front surface portion 40, an upper surface portion 41, a back surface portion 42, and left and right side surface portions 43 and 44. The work space G is a space having a horizontally long and substantially rectangular parallelepiped shape. A front surface 45 of a horizontally long rectangular shape is provided on the front surface of the case portion 11. The front opening 45 is used by an operator for carrying the target device M into or out of the work space G, for example.

  As shown in FIGS. 1 and 2, the front opening 45 of the case portion 31 is closed by a left first front door 51, a central third front door 52, and a right third front door 53. . The front opening 45 can be opened and closed by manually sliding the first front door 51, the third front door 52, and the third front door 53 in the left-right direction (X direction).

  Since the 1st front door 51, the 3rd front door 52, and the 3rd front door 53 are the slide sash doors which have transparent tempered glass, respectively, an operator is the 1st front door 51 and the 3rd front door 52. Through the third front door 53, it is possible to directly observe equipment in the work space G, such as a balance.

  The left and right side surfaces 43 and 44 shown in FIGS. 3 and 4 are preferably tempered glass transparent plates so that the inside of the work space G can be seen. A glove port 46 is provided on the left side surface portion 43. The glove port 46 is an insertion opening for inserting a worker's hand and performing work in the work space G.

  In step ST5 of FIG. 10, a predetermined process is performed on the processing object M in the work space G in the enclosure 4 shown in FIG. The predetermined processing is, for example, an operation of weighing the processing object M such as a dried crystal sample with a balance and subdividing it into a predetermined amount, but is not particularly limited.

  In step ST6 of FIG. 10, during processing of the processing object M in the enclosure 4, the drive fan 70 shown in FIG. 3 is driven by a command from the control unit 100 shown in FIG. The air BR containing a hazard substance such as powder in the case part 31 of the fourth case 31 is taken into the main body 71 through the exhaust pipe 220 of the exhaust system 200.

  As a result, the prefilter 61 in FIG. 3 removes large substances from the air BR containing the hazard substances such as powders in advance, and then the HEPA filter 62 removes smaller substances from the air BR and cleans them from the exhaust section 72. It is discharged as converted air N. Powder or the like is no longer scattered from the work space G in the enclosure 4, and the surrounding environment where the containment system 1 is disposed is not adversely affected.

  Thereafter, in step ST7 of FIG. 10, the processed processing object M is taken out from the work space G in the enclosure 4 shown in FIG.

  As described above, when the used filters 15, 61, 62 shown in FIGS. 5 and 3 are collected and replaced with new filters, the used filters 15, 61, 62 are preferably accommodated respectively. More preferably, the filter 15, 61, 62 can be removed in the state where the filter 15, 61, 62 is put together with the bag for storage in the collection bag.

  Thereby, when the used filters 15, 61, 62 are collected and replaced, it is possible to prevent hazard substances such as powder from scattering from the used filters 15, 61, 62 to the surroundings. A method of removing the filters 15, 61, 62 can be called a bagout method (Bagout method).
