[1-6. Structure of Moving Mechanism]
Description of the moving mechanism of the tray will be given with reference to FIGS. 6 to 11.
FIG. 6 is a perspective view illustrating the configuration of the periphery of the slide tray according to embodiment 1, and FIG. 7 is a top view thereof. FIG. 8 is an end face view along line 8-8 of FIG. 7 and FIG. 9 is an end face view along line 9-9 of FIG. 7.
As illustrated in FIGS. 6 and 7, the tray 160 is movably attached on the bottom plate 155 of the transport space C. The bottom plate 155 has rails R1 (first engaging part) mounted. The rails R1 are engaged with the rails R2 (second engaging part) mounted to the back face of the mounting face of the tray 160. The rails R1 and R2 configure the moving mechanism that enables the tray 160 to move. The tray 160 has a plurality of penetrating holes 166 that are formed to penetrate from the mounting face to the back face so to enable sterilized gas to come around easily. Both ends of the tray 160 in the moving direction (X direction) have grips 164a, 164b formed in a manner curved downward from the mounting face. Therefore, the tray 160 can be easily pulled out into the first workspace A or the second workspace B by the worker holding and pulling the grips 164a, 164b when moving the tray 160. Additionally, the two ends in the direction (Y direction) orthogonal to the moving direction of the tray 160 have erected parts 165 formed to erect upward from the mounting face. Thereby, articles used for work are restrained from dropping when the tray 160 is moved to the first workspace A or the second workspace B while in a state having the articles placed on the mounting face. Further, a cushion member 167 is attached with a nut 168 to the corner of the tray 160 on the rotating axis side (−Y direction side) of the first and the second doors D1, D2. The cushion member 167 is a resin or a silicon member having a curved surface and is provided to abut against the first and the second doors D1, D2 with the curved surface. Therefore, the cushion member 167 not only restrains the first and the second doors D1, D2 and the tray 160 from being damaged when the tray 160 comes into contact with the first and the second doors D1, D2, but also restrains dust (particles) from being generated by a hitting. Furthermore, a stopper for restraining the moving range of the tray 160 is provided to the moving mechanism. Note that, the description of the stopper will be given later. The stopper restrains a worker from excessively pulling the tray 160 thereby enabling to restrain articles from dropping and the like.
Description of the rails R1 and R2 that configure the moving mechanism of the tray 160 will be given next with reference to FIGS. 8 to 11. FIGS. 10 and 11 are perspective views illustrating the first and second rails according to embodiment 1. FIGS. 10 and 11 illustrate the tray 160 etc. seen from below (−Z) toward above (+Z). FIG. 10 illustrates the tray 160 in a state when provided inside the pas box 150 (FIG. 5). FIG. 11 illustrates the tray 160 in a state when moved to the first workspace A side. Note that, the first guide units 156A, 156B in FIGS. 10 and 11 respectively correspond to the first guide unit 156 on the −Y side and the first guide unit 156 on the +Y side of the two first guide units 156 in FIG. 9. Further, the second guide units 161A, 161B in FIGS. 10 and 11 respectively correspond to the second guide unit 161 on the −Y side and the second guide unit 161 on the +Y side of the two second guide units 161 in FIG. 9. Furthermore, the spacers 162A, 162B in FIGS. 10 and 11 respectively correspond to the spacer 162 on the −Y side and the spacer 162 on the +Y side of the two spacers 162 in FIG. 9. Note that in FIGS. 10 and 11, descriptions of the plurality of holes are partially omitted.
The rails R1 and R2 are used for moving the tray 160 along the X direction between the first location and the second location. The first location is a location in the first workspace A. When the tray 160 is moved to the first location, at least the grip 164a of the grips 164a and 164b will be provided in the first workspace A. The second location is a location at, for example, the opposite side of the first location in the X direction with regard to the transport space C. The second location is a location in the second workspace B. When the tray 160 is moved to the second location, at least the grip 164b of the grips 164a and 164b will be provided in the second workspace B.
The rail R1 (FIG. 9) includes the first guide units 156 and nuts 157 which fix the first guide units 156 to the bottom plate 155. The first guide units 156 are formed with resin. The first guide units 156 are in elongated shapes extending along the X direction. The two first guide units 156 are provided in parallel to the X direction. The two first guide units 156 (156A, B in FIGS. 10 and 11) are arranged in the Y direction intersecting the moving direction (X direction). The two first guide units 156 are each configured of a part (also called the “first part”) fixed to the bottom plate 155 with the nuts 157, a part (also called the “second part”) extending to erect upward (+Z direction) from the part which is to be fixed, and a part (also called the “third part”) bending in the outward direction (Y direction) between the two first guide units 156 above the part extending upward. Hereby, a space (gap) for the second guide unit 161 to enter is formed between the bended part of the first guide unit 156 and the bottom plate 155. In other words, the one first guide unit 156A (second rail) of the two first guide units 156 has the aforementioned first to third parts, and is bended such that a space (also called a “first space”) is formed between the third part of the first guide unit 156A and the bottom plate 155. The third part of the first guide unit 156A is bended in the Y direction toward the direction (−Y) apart from the other first guide unit 156B. Further, the first guide unit 156B (first rail) has the aforementioned first to third parts, and is bended to form a space (also called a “second space”) between the third part (second bended piece) of the first guide unit 156B and the bottom plate 155. The third part (first bended piece) of the first guide unit 156B is bended in the Y direction toward the direction (+Y) apart from the first guide unit 156A.
The rail R2 includes second guide units 161 and spacers 162 positioned between the tray 160 and the second guide units 161, and nuts 163 for fixing the second guide units 161 and the spacers to the back face of the tray 160. The second guide units 161 are formed with stainless steel plates which are made of metal. The spacers 162 are formed of resin. The second guide units 161 are in elongated shapes extending along the X direction. The two second guide units 161 are provided in parallel (X direction) to the first guide unit 156. The two second guide units 161 (161A, B in FIGS. 10 and 11) are arranged in the Y direction intersecting the moving direction (X direction). The two second guide units 161 are each configured of a part (also called the “fourth part”) fixed to the spacer 162 (162A, B in FIGS. 10, 11) with the nuts 163, a part (also called the “fifth part”) extending to bend downward (−Z direction) from the part which is to be fixed to the spacer 162, and a part (also called the “sixth part”) bending in the inward direction (Y direction) between the two second guide units 161 below the part extending downward. Hereby, a space for the first guide unit 156 to enter is formed between the second guide unit 161 and the spacer 162. In other words, the second guide unit 161A (fourth rail) has the aforementioned fourth to sixth parts and the sixth part (second inserting piece) of the second guide unit 161A is bended to be inserted in the first space. The sixth part of the second guide unit 161A is bended in the Y direction toward the direction (+Y) approaching the second guide unit 161B. And the second guide unit 161B (third rail) has the aforementioned fourth to sixth parts and the sixth part (first inserting piece) of the second guide unit 161B is bended to be inserted in the second space. The sixth part of the second guide unit 161B is bended in the Y direction toward the direction (−Y) approaching the second guide unit 161A. Here the spacers 162 are provided so that the grips 164a, 164b formed to the two ends of the tray 160 in the moving direction (X direction) do not hit the first guide unit 156 when the tray 160 is moved.
With the above configuration, the rails R1 and R2 are engaged so that the first guide unit 156 and the second guide unit 161 engage in a latching manner while the tray 160 is freely movable in both sides in the X direction. The rails R1 and R2 are engaged in a manner prevented from moving away from each other in the Z direction by the first guide unit 156 and the second guide unit 161 being engaged.
Description of the first and the second stoppers that restrain the movement of the tray 160 will be given in the following with reference to FIGS. 10 and 11.
<Structure>
The first guide unit 156B and the second guide unit 161B have provided a protrusion 51B (first protruding piece) and a rest 52B (first abutment) that exhibit a function as the first stopper. The protrusion 51B and the rest 52B restrain the tray 160 moved to the first location from moving further to the first isolator 110 side (−X).
The protrusion 51B is a protruding piece that protrudes from the sixth part of the second guide unit 161B toward the −Y side in the second space. For example, the protrusion 51B is provided on the +X side with regard to approximately the center of the second guide unit 161B in the longitudinal direction (X direction) of the second guide unit 161B.
The rest 52B is an abutment that abuts and engages the protrusion 51B in the second space to restrain the tray 160 moved to the first location from moving further to the first isolator 110 side (−X). In other words the rest 52B has a function of making the tray 160 come to a rest at the first location by abutting against the protrusion 51B. The rest 52B is detachably (freely detachable) mounted to the −X side end part of the first guide unit 156B so that the tray 160 can be provided on the moving path of the protrusion 51B when moving the tray 160 in the −X direction. The rest 52B includes a first piece 521 and a second piece 522. The first piece 521 is in a state substantially parallel to the YZ plane, and is detachably attached to the end part on the −X side of the first guide unit 156B with, for example, a screw 523. The second piece 522 is bended from the end on the −Z side of the first piece 521 toward the +X side so to be inserted in the second space.
The first guide unit 156A and the second guide unit 161A have a protrusion 51A (second protruding piece) and a rest 52A (second abutment) that exhibit a function as the second stopper. The protrusion 51A and the rest 52A restrain the tray 160 moved to the second location from moving further to the second isolator 130 side (+X).
The protrusion 51A is a protruding piece that protrudes from the sixth part of the second guide unit 161A toward the +Y direction in the first space. For example, the protrusion 51A is provided on the −X side with regard to approximately the center of the second guide unit 161A in the longitudinal direction (X direction) of the second guide unit 161A.
The rest 52A is an abutment that abuts and engages the protrusion 51A in the first space to restrain the tray 160 moved to the second location from moving further to the second isolator 130 side (+X). In other words the rest 52A has a function of making the tray 160 come to a rest at the second location by abutting the protrusion 51A. The rest 52A is detachably (freely detachable) mounted to the +X side end part of the first guide unit 156A so that the tray 160 can be provided on the moving path of the protrusion 51A when moving the tray 160 in the +X direction. Note that the configuration of the rest 52A is similar to that of the rest 52B and thus the description thereof is omitted.
<Mounting>
The tray 160 to which the second guide units 161A, 161B are fixed, is mounted to the bottom plate 155 to which the first guide units 156A, 156B are fixed by, for example, the first mounting procedure or the second mounting procedure.
First Mounting Procedure
The rest 52A is disengaged from the first guide unit 156A. The end parts on the −X side of the sixth part of the second guide units 161A, 161B are each inserted into the first and second spaces from the +X side end of the first guide units 156A, 156B. In other words the tray 160 is mounted to the bottom plate 155 by sliding from the second workspace B side (+X) toward the transport space C side (−X). Thereafter, the rest 52A is mounted to the first guide unit 156A.
Second Mounting Procedure
The rest 52B is disengaged from the first guide unit 156B. The end parts on the +X side of the sixth part of the second guide units 161A, 161B are each inserted into the first and second spaces from the −X side end of the first guide units 156A, 156B. In other words the tray 160 is mounted to the bottom plate 155 by sliding from the first workspace A side (−X) toward the transport space C side (+X). Thereafter, the rest 52B is mounted to the first guide unit 156B.
Movement
For example, when a force is applied to the grip 164a in a direction from +X to −X, the tray 160 moves to the first isolator 110 side. When the tray 160 moves to the first location, the protrusion 51B and the rest 52B abuts and engages with each other. With such circumstances, the tray 160 is restrained from moving further to the first isolator 110 side and comes to a standstill at the first location. And for example, when a force is applied to the grip 164b in a direction oriented from −X to +X, the tray 160 moves to the second isolator 130 side. When the tray 160 moves to the second location, the protrusion 51A and the rest 52A abuts and engages with each other. With such circumstances, the tray 160 is restrained from moving further to the second isolator 130 side and comes to a standstill at the second location.
[2. Effects Etc.]
The isolator system 100 according to the present disclosure includes a first isolator 110 forming the first workspace A that is hermetically sealed from the ambient environment, a second isolator 130 forming the second workspace B that is hermetically sealed from the ambient environment, and a pass box 150 being provided between the first isolator 110 and the second isolator 130 and forming a transport space C that can communicate the first workspace A and the second workspace B while maintaining airtightness. The pass box 150 has a plate-like tray 160 for placing thereon articles used for work and a moving mechanism (rails R1 and R2) which enables the tray 160 to move to both the first isolator 110 side and the second isolator 130 side, at the bottom plate 155 of the transport space C. The grip 164a (first end) on the first isolator 110 side is positioned in the first workspace A when the tray 160 is moved to the first isolator 110 side, and the grip 164b (second end) on the second isolator 130 side is positioned in the second workspace B when the tray 160 is moved to the second isolator 130 side.
Hereby, for example, articles placed on the tray 160 in the pass box 150 can be easily taken out regardless of whether the worker works at the first isolator 110 or the second isolator 130. Therefore, the operability of the isolator system 100 can be improved.
Further, in the isolator system 100 according to the present disclosure, the first isolator 110 has a first opening H1 formed to the second side face 117a on the pass box 150 side, and the second isolator 130 has a second opening H2 formed to the side face 137b on the pass box 150 side. The pass box 150 has formed a first delivery opening 153 hermetically connected to the first opening H1 on the right side face 117a of the first isolator 110 and a second delivery opening 154 hermetically connected to the second opening H2 on the side face 137b of the second isolator 130. The first delivery opening 153 has provided a first door D1 capable of sealing the first delivery opening 153, and the second delivery opening 154 has a second door D2 capable of sealing the second delivery opening 154. The first door D1 can open and close a side of the first workspace A and the second door D2 can open and close a side of the second workspace B.
Hereby, for example, the doors on the two sides are opened to and close the inside so that the mounting area of the tray 160 can be secured and also allows the tray 160 to be taken out easily into the first workspace A or the second workspace B. Therefore, the operability of the isolator system 100 can be improved. Although in the present embodiment, the first door D1 was provided to the first delivery opening 153, and the second door D2 was provided to the second delivery opening 154, a configuration in which the first door D1 is provided to the first opening H1 and the second door D2 is provided to the second opening H2 can be adopted. In other words, it will do as long as at least one of the doors provided on the two sides can open and close the inside.
Furthermore, the moving mechanism of the isolator system 100 according to the present disclosure is provided to the bottom plate 155 of the transport space C and includes a rail R1 (first engaging part) which guides the movement of the tray 160 and a rail R2 (second engaging part) which is provided on the back side of the mounting face of the tray 160 for having articles used in work mounted thereon, and is engaged to the rail R1.
Hereby, for example, the tray 160 is strengthened so that the tray 160 is movable while having an article stably placed on the mounting face of the tray 160. And thus the operability of the isolator system 100 can be improved.
Yet further still, the two rails R1 and R2 according to the isolator system 100 of the present disclosure are linear and in parallel to the moving direction of the tray 160.
Hereby, for example, the movement of the tray 160 is made smooth. And thus the operability of the isolator system 100 can be improved.
Even further still, the two ends (first end and the second end) of the tray 160 according to the isolator system 100 of the present disclosure has formed a grip 164 bended downward from the mounting face of the tray 160.
Hereby, for example, the worker can hold the grips 164a, 164b to pull out the tray 160 allowing the tray 160 to be pulled out easily. And thus the operability of the isolator system 100 can be improved.
Even further still, the rail R1 according to the isolator system 100 of the present disclosure includes a spacer 162 which is fixed to the back face of the mounting face of the tray 160, and a first guide unit 161 which is fixed to the spacer 162 and restrains the tray 160 from coming off of the rail R2. The length of the spacer 162 in the vertical direction (Z direction) is configured to be longer than the length of the grips 164a, 164b in the vertical direction (Z direction).
Hereby, the moving range of the tray 160 can be widened. And thus the operability of the isolator system 100 can be improved.
Even further still, the moving mechanism of the isolator system 100 according to the present disclosure has provided a protrusion 51B and a rest 52B as the first stopper and a protrusion 51A and a rest 51A as the second stopper which restrain the moving range of the tray 160.
Hereby, the tray 160 can be restrained from being excessively pulled out by the worker and dropping and the like of articles can be restrained. And thus the operability of the isolator system 100 can be improved.
Even further still, the first guide units 156A, 156B and the second guide units 161A, 161B are each two linear members parallel to the moving direction (X direction) of the tray 160. The protrusion 51B, the rest 52B, the protrusion 51A, and the rest 51A are respectively provided to the second guide unit 161B, the first guide unit 156B, the second guide unit 161A and the first guide unit 156A. The first guide units 156A, 156B and the second guide units 161A, 161B have the first and second stoppers provided in this way.
Hereby, for example, the first and second stoppers can be miniaturized. And thus, for example, the space of the transport space C can be widened.
Even further still, the protrusion 51B protrudes from a location to the side closer to the +X side end of the second guide unit 161B. The protrusion 51A protrudes from a location to the side closer to the −X side end of the second guide unit 161A. The rest 52B engages with the protrusion 51B at the −X side end of the first guide unit 156B when exercising the function as the first stopper. The rest 52A engages with the protrusion 51A at the +X side end of the second guide unit 156A when exercising the function as the second stopper.
Hereby, for example, the tray 160 can be made to come to a standstill at the first or the second locations. Thus for example, there can be provided a convenient isolator system 100 which makes the moving of the devices mounted on the tray 160 to the first workspace A and the second workspace B easy.
Even further still, the rests 52A, 52B are respectively detachably attached to the first guide units 156A, 156B. Therefore, the tray 160 can be relatively easily mounted to the bottom plate 155 according to, for example, the first or the second mounting procedure.
Even further still, the first guide units 156A, 156B are in elongated states extending along the moving direction (X direction) of the tray 160 and are arranged in the Y direction that intersects the X direction. The second guide units 161A, 161B are in elongated states extending along the X direction and engage with the first guide units 156A, 156B. Since the each of the guide units are, for example, arranged in the Y direction in twos, for example, the tray 160 can be moved while the tray 160 is maintained in a substantially parallel state.
Even further still, the third parts of the first guide units 156A, 156B are bended to form a first and a second space between the bottom plate 155. The sixth part of the second guide units 161A, 161B is inserted between the first and the second spaces to move the tray 160 in the X direction.
Therefore, the tray 160 can be certainly moved in the X direction while the movement of the tray 160 in the vertical direction (Z direction) is in a restrained state.
Even further still, the rest 52A is detachably attached to the +X side end of the first guide unit 156A. The rest 52B is detachably attached to the −X side end of the first guide unit 156B. Hereby, the rests 52A, 52B can be easily detached. Therefore, the tray 160 can be further easily mounted to the bottom plate 155 by, for example, the first or the second mounting procedure.
