Description

  The present invention relates to a container lifting and lowering device for raising and lowering another container so as to horizontally move a lowermost container or the like of a multi-tiered stacked container, and a container transfer device attached thereto.

  The steamer used for steaming glutinous rice, steamed sweets and the like housed inside is usually square-shaped, with projections formed at the four corners. And when steaming the contents, in order to stack multiple stages of steaming on the steaming table and sequentially withdraw it from the lowest stage of steaming first, the upper stage steaming except this is picked up and lifted . At that time, if it is done by hand, it is heavy and extremely heavy labor.

  In order to reduce the burden, a pantograph link is provided by sandwiching the steam, and by operating the handle that can be expanded and contracted by the rotation operation of the worm gear, an air gap is formed between the lowermost stage and the other steams. There has been proposed a steaming elevating device capable of extracting the steamed state of (see Patent Document 1).

  In addition, using the principle of leverage, the elevator rods connected to the chain wound around the sprocket automatically lift the vapor other than the lowermost to form a space between the lowermost and the lowermost. There has been proposed a steam conveying device for pulling out the steam while lifting it (see Patent Document 2).

Japanese Patent Application Laid-Open No. 10-295543 JP-A-8-168438

  However, in the proposal of Patent Document 1, since the handle operation is manually performed, considerable labor is still required in consideration of the weight of the steam which is stacked in the presence of the contents. Here, in a food factory where steaming is mainly used, there are usually many people who are relatively weak like women such as housewives. Therefore, in this proposal, the person who can actually work is limited, and the load on the person tends to be excessive.

  In the proposal of Patent Document 2, since the vapor is lifted by suspending the vapor by the rotational force of the sprocket, it is difficult to take balance in consideration of the weight and size of the vapor, and the contents are unevenly steamed up and down at the time of lifting. Unevenness may occur, or there may be a collapse of cargo because the steam is not stacked in order. In addition, in this proposal, there is a possibility that parts such as a chain and a ball screw may rust over time and the function of the device may be deteriorated or damaged. On the other hand, when a rust preventive such as grease is used, the apparatus is located above the steam, so there is a risk of contamination with the food in the steam, which is not preferable from the viewpoint of hygiene. Furthermore, since the apparatus configuration spans up and down sandwiching the steam, there is also a problem that the installation becomes large and the installation cost increases.

[First embodiment]
FIG. 1 is a photograph showing an example of the overall configuration of a container lifting apparatus according to a first embodiment of the present invention, and FIG. 2 is a photograph showing the main part thereof.

  As shown in FIG. 1, the container lifting apparatus 1 of the present invention mainly includes a control unit 10, an apparatus main body 20, and a container transfer member (hereinafter simply referred to as a "transfer member") 30 connected thereto. Configured

  The apparatus main body 20 is electrically connected to the control unit 10 by the cord 15, and the operation of the elevating mechanism provided therein is controlled by the operation of the control unit 10.

  The apparatus main body 20 has a symmetrical shape with the transport member 30 interposed therebetween, is formed such that the top 21 is connected to the transport member 30 without any level difference, and serves as a mounting table on which a plurality of containers of the same shape are stacked. In the example of FIG. 1, the steamers 50a and 50b are stacked in two stages as containers, and when the steamers are stacked in this way, the top 21 functions as a steaming platform. In the illustrated example, substantially U-shaped reinforcing plates 22 are attached to both ends of the conveying member 30 of the top 21 in order to prevent positional displacement of stacked containers in the illustrated example. Further, in the example of FIG. 1, a cover 60 is attached to the lower portion of the device body 20 in order to protect the internal mechanism. Needless to say, steaming may be further stacked.

  When the cover 60 is removed, as shown in FIG. 2, the apparatus main body 20 is mainly composed of a cylindrical cam 70 as an elevating mechanism for the second stage steamer 50b from the bottom and an elevating rod 80 functioning as this follower. The provided mechanism is provided. In other words, they are provided below the steamed vessels 50a and 50b. The elevating mechanism is provided in a symmetrical shape forming a pair on the front side and the rear side of the steamers 50a and 50b stacked with the reinforcing plate 22 in between, and the similar mechanism is also provided on the opposite side across the transport member 30. . That is, as shown in FIG. 1, the steaming pipes 50 a and 50 b have a square opening surface, and the projections 51 a and 51 b are formed at the four corners, and an elevating mechanism is provided corresponding to each of these projections. In the illustrated example, in order to improve the stability at the time of installation of the device main body 20, leg portions 23 in contact with the floor are provided at four corners.

  Next, the cylindrical cam 70 will be described. FIG. 3 is a view showing a cylindrical cam, where (a) is a side view and (b) is a partially broken front view. FIG. 4 is a photograph showing an example of a cylindrical cam.

  As shown in FIGS. 3 and 4, the cam grooves 71 formed in the cylindrical cam 70 are straight lines (hereinafter simply referred to as "straight lines") 72a extending along a pair of height directions (vertical directions). An edge is constituted by 72b, inclined lines 73a and 73b, and insertion parts 74a and 74b between them.

  The inclined lines 73a and 73b are formed such that one inclined line 73a is relatively on the upper end side and the other inclined line 73b is relatively equal on the lower end side. The edges of the inclined lines 73a and 73b are formed in a curved shape because they are formed on the circumference of the cylindrical cam 70 as particularly shown in FIG.

  The straight lines 72a and 72b are formed such that the straight line 72a is located on the upper end side of the straight line 72b, that is, higher when installed, through the inclined lines 73a and 73b, and the upper end of the straight line 72a and the lower end of the straight line 72b The insertion parts 74a and 74b are respectively formed continuously.

  In the insertion parts 74a and 74b, the insertion part 74a on the upper end side is formed in a long hole shape, while the insertion part 74b on the lower end side is formed in a substantially semicircular shape. Further, since the upper end side insertion portion 74a is formed to be longer in this manner, the straight line 72a located at a relatively high position extends so as to constitute one end of the insertion portion 74a. It is formed longer than the straight line 72b at the lower position.

  The straight line 72a at a relatively high position is formed continuously with the upper end of the lower end side inclined line 73b at the lower end, while the straight line 72b at a relatively lower position is an upper end inclined line at the upper end It is formed continuously with the lower end of 73a. The portions where the straight lines 72a and 72b and the inclined lines 73a and 73b are connected are formed in a slightly curved shape for the convenience of sliding of the follower and manufacturing.

  As described above, the cam groove 71 is continuously connected to the inclined line 73a → the straight line 72b → the insertion portion 74b → the inclined line 73b → the straight line 72a → the insertion portion 74a → the inclined line 73a.

  Next, the configuration and operation of the lift bar 80 will be described. FIG. 5 is a view for explaining the operation of the elevating rod, and FIG. 6 is a photograph showing a state in which the top plate of the elevating rod is in contact with the projection of the steaming rod.

  As shown in FIG. 5, a pin (contactor) 81 in contact with the cam groove 71 is attached to the lower end portion of the elevating rod 80, and the pin 81 as a follower of the cylindrical cam 70 by sliding on the cam groove 71. Function. In addition, a top plate 82 is attached to the top, and as shown in FIG. 6, by supporting the projections 51 b of the second stage of the steam 50 b from the bottom, the steam can be raised and lowered.

  In the top plate 82, the back side (the side away from the main body of the elevating rod 80) which is the contact portion of the protrusion 51b is formed wider than the base end side, and can reliably support the steam 50b when in contact with the protrusion 51b On the other hand, the other parts are made smaller to reduce the member cost.

  In this configuration, when raising the steam, at first, the pin 81 is inserted into the insertion portion 74b on the lower end side. In this state, when the mechanism is operated by the operation of the control unit 10 (see FIG. 1) described above, the pin 81 first rises along the edge of the straight line 72b located at a relatively low position (upper and lower in FIG. See arrow). By this rise, the position of the top plate 82 becomes higher than the position of the protrusion 51 a of the lowermost stage of the steam 50 a shown in FIGS. 1 and 2.

  Subsequently, when the pin 81 ascends to the upper end of the edge of the straight line 72b, it moves to the edge of the inclined line 73a on the upper end side, and along with this, the lift bar 80 starts pivoting (see circular arrow in FIG. 5) ). When the pin 81 moves to the upper end of the edge of the inclined line 73a, the rotation is finished, and at this stage, the top plate 82 faces the bottom of the protrusion 51b (see FIG. 6) of the second stage of steam 50b from the bottom.

  Next, the pin 81 moves to the insertion portion 74a and ascends to the upper end. At this time, after the top plate 82 abuts against the projection 51b, the elevating rod 80 further rises slightly to create a gap between the lowermost steaming 50a and the second steaming 50b from the bottom. Stop rising. That is, the upper end side insertion portion 74a is at least able to rise until the top plate 82 abuts against the protrusion 51b and a gap is generated between the lowermost steaming layer 50a and the second lower steaming layer 50b. It needs to be formed in the distance. Therefore, the insertion portion 74a on the upper end side is formed in a long hole shape.

  As a result, the top plate 82 supports the steamer 50b with the projections 51b, and the lowermost steamer 50a can be moved in the horizontal direction, so that it is moved to the transport member and transported.

  On the other hand, when lowering the steam 50b, when the mechanism is operated by the operation of the control unit 10 (see FIG. 1), the pin 81 is at the edge of the straight line 72a relatively higher than the insertion portion 74a on the upper end side. It descends along (see the up and down arrows in FIG. 5). At this time, as shown in FIG. 6, the top plate 82 descends while supporting the protrusions 51b of the steam 50b until the steam 50b contacts the top 21 of the apparatus main body 20, that is, the steam 50b becomes the lowermost stage. Let down.

  Subsequently, when the pin 81 is lowered to the lower end of the straight line 72a, the pin 81 moves to the edge of the inclined line 73b on the lower end side, and the elevating rod 80 starts rotating accordingly (see circular arrow in FIG. 5) The top 82 of the top 82 is separated from the steam 50 b, and the contact with the protrusion 51 b is released. The contact release between the top plate 82 and the protrusion 51 b may be released by lowering the vapor 50 b after the straight line 72 a of the pin 81 is lowered, and further lowering the pin 81. In any case, if the lift bar 80 is not rotated, the top plate 82 hits the projection 51a of the lowermost steamer 50a at the time of rising again, and the desired lifting operation becomes impossible. .

  Next, when the pin 81 moves to the lower end of the inclined line 73b, the lift bar 80 finishes rotating. Furthermore, the pin 81 enters the fitting portion 74b on the lower end side and stops its movement, and the lowering of the elevation 80 also stops accordingly. The inclined line 73b is formed to have the same length as the length of the inclined line 73a on the upper end side so that the elevating rod 80 can turn so as to return to the posture before rising.

  As described above, in the container lifting apparatus 1 according to the first embodiment of the present invention, the top plate 82 is provided on the lifting rod 80 functioning as a follower of the cylindrical cam 70, and the top plate 82 is the protrusion 51a of the lowermost steaming 50a. The cam groove 71 is formed in the cylindrical cam 70 so as to abut on the protrusion 51b of the steam 50b located at the second stage from the bottom, although it does not. Further, the cam groove 71 was formed so that the steam 50b could be lowered to the lowermost stage while maintaining the top plate 82 in contact with the projection 51b. Therefore, the steamer 50b can be automatically raised and lowered only by the mechanical operation of the cylindrical cam 70 and the lift bar 80.

  The material of the cylindrical cam 70 and the elevating rod 80 is not particularly limited as long as it can be applied. For example, a metal such as stainless steel that is hard to rust and is lightweight and inexpensive is preferable.

  The edge of the cam groove 71 is composed of the above-mentioned straight lines 72a and 72b, inclined lines 73a and 73b, and insertion parts 74a and 74b, and if the desired operation of the present invention is possible, the length and position are the device body 10 The size of steamer 50a, 50b may be taken into consideration as appropriate.

  The lift bar 80 is configured to be able to move up and down while maintaining balance between front and back. The configuration will be described based on FIG. FIG. 7 is a photograph showing a chain gear constituting the container lifting and lowering device of the present invention.

  As shown in FIG. 7, a balance plate 90 is attached via a bearing 85 between the pair of front and rear lifting rods 80 and 80.

  In the central portion of the balance plate 90, a circular insertion hole 91a is formed at the central position of the balance plate 90, and a laterally long oval insertion hole 91b is formed at a slightly rearward position thereof. On the other hand, a chain gear 100 is provided in the apparatus main body 20 in a direction (vertical direction) perpendicular to the balance plate 90.

  The chain gear 100 mainly includes an upper sprocket 101a and a lower sprocket 101b, and a chain 102 wound around the upper sprocket 101a and the lower sprocket 101b. The chain 102 is inserted into the insertion hole 91a having a circular shape on one side and the insertion hole 91b having an oval shape on the other side, and the chain 102 and the balance plate 90 are engaged in the insertion hole 91a. Is not in contact with the balance plate 90. Further, one end of an auxiliary chain gear 103 to which power is transmitted from a motor (not shown) is hung on the upper sprocket 101a. Furthermore, in the example of FIG. 7, stoppers 110 for stopping the operation of the lifting and lowering mechanism of the balance plate 90 are respectively provided above and below the balance plate 90.

  With this configuration, when the chain gear 100 drives the motor 103, power is transmitted from the auxiliary chain gear 104 via the upper sprocket 101a, and rotation of the chain 102 is started. Along with the rotation of the chain 102, the balance plate 90 is moved up and down via the circular insertion hole 91a to be stopped by the upper and lower stoppers 110 so that the up and down movement is stopped. That is, since the balance plate 90 is lifted and lowered while being suspended by the chain 102 at the central position, the balance plate 90 can be raised and lowered in a horizontal state.

  In addition, the elevating bar 80 moves up and down as the balance plate 90 moves up and down via the bearing 85. Therefore, the balance plate 90 does not cause a bias between the front and rear lifting rods 80 and 80, and the balance can be maintained.

  Next, the transport member 30 will be described. 8 is a photograph showing the container conveyance member, FIG. 9 is a side view showing the container drawer provided in the container conveyance member, FIG. 10 is a photograph showing the main part of the lower rail of the container conveyance member, and FIG. It is a photograph which shows the state which hung the stopper on steaming.

  As shown in FIG. 8, the transport member 30 is composed of a plurality of longitudinal members, and at the center, rails 31 extending along the longitudinal direction of the transport member 30 are provided on both sides of the rail 31. A transport bar 32 is provided which extends two by two in the same manner. The lowermost vapor 50 a drawn from the apparatus main body 20 is conveyed on the rails 31 and the conveying rods 32.

  The proximal end side of the transport member 30 is attached to the apparatus main body 20 via a mounting tool such as a screw by a proximal end mounting plate 33a. On the other hand, a stand 34 supporting the conveying member 30 in the horizontal direction is attached to the end side through the end side attachment plate 33 b.

  At the lower part of the rail 31, a container drawer 120 is straddled on the rail 31 at the upper surface, whereby the rail 31 can slide. As shown in FIG. 9, the container extractor 120 mainly includes a case 121, a shaft 122, a pair of pinions 123a and 123b, and a hook (a hook) 124.

  The case 121 has a box shape, and accommodates the shaft 122 and the pinions 123a and 123b inside. Both ends of the shaft 122 are provided outside the case 121, and the main body portion between the two passes through the inside of the case 121. Grooves 122a are formed in the main body at predetermined intervals, the lower pinion 123b is engaged with the grooves 122a, and the upper pinion 123a is engaged with the pinion 123b. A hook 124 is provided on the upper pinion 123 a so as to protrude from the case 121. With this configuration, in the container extractor 120, the hook 124 is moved up and down by the forward and backward movement of the shaft 122 (see the front and rear arrows in FIG. 9) (see the arcuate arrow in FIG. 9). That is, it has a so-called rack-and-pinion configuration.

  Here, as shown in FIG. 10, at a position below the rail 31 at the base end of the transport member 30, a biasing member 35 in which a spring or the like is accommodated is provided. Therefore, when the container drawer member 120 is slid to the base end side along the lower end of the rail 31, one end of the shaft 122 abuts against the biasing member 35, and the hook 124 is moved upward of the rail 31 by the biasing force. Stand out. The auxiliary rail 36 of the transport member 30 passes through the center of the lower portion of the container drawer 120, and guides the slide of the container drawer 120 together with the rail 31 to drop or shift the container drawer 120. It is preventing etc. In addition, a chain rail 37 is provided in the auxiliary rail 36, and the container extractor 120 can be made to travel automatically by transmitting power.

  In addition, as shown in FIG. 11, the reinforcing rods 52 are inserted between the protrusions 51a and 51b in the steaming rods 50a and 50b, and the hooks 124 protruding upward are attached to the reinforcing rods 52 of the steaming rod 50a located at the lowermost stage. Can be suspended. As a result, when the steam 50a can move in the horizontal direction, the top of the transport member 30 can be pulled out by the container extractor 120 in a state in which the hook 124 is latched.

  That is, since the container extractor 120 slides on the lower portion of the rail 31, the evaporation of the steam 50a is carried out without being exposed on the conveying member 30 except that the hook 124 protrudes upward at the time of hooking to the steam 50a. It is possible to transport the steam 50a to the end of the transport member 30 without removing the container extractor 120.

  The transport member 30 may be removed from the apparatus main body 20 and attached to another container lifting device as a transport device.

[Second form]
Subsequently, a container lifting and lowering apparatus according to a second embodiment of the present invention will be described. FIG. 12 is a photograph showing an example of the overall configuration of the container lifting apparatus of the second embodiment, and FIG. 13 is a photograph showing the configuration of the gear member. The container lifting and lowering apparatus 1 of the first embodiment described above mainly lifts and lowers the container by the lifting and lowering mechanism using the cylindrical cam 70, but the container lifting and lowering apparatus 151 of the second embodiment shown in FIG. It is an apparatus which consists of a mechanism using expansion-contraction movement of an energizing member, and it is considered as compact composition compared with container rise-and-fall device 1 of the 1st form.

  As shown in FIG. 12, the elevating mechanism of the container elevating device 151 includes an elevating rod 160, a spring 170 as one biasing member, an engagement plate 180, a gear member 190, a pivoting rod 200, and a top plate And 210 mainly. Further, the elevating mechanism is supported by the pivot rods 200 being connected by the pair of support rods 220 via the pair of bearings 205. The configuration of the support rod 220 is substantially the same as that of the lift rod 80 in the lift device 1 of the first embodiment except that the cylindrical cam 70 and the top plate 82 are not provided. The plate 90 and the chain gear 100 can move up and down while maintaining the balance.

  Moreover, in the example shown in FIG. 12, the protrusion 51a (51b) of the steamed rice 50a (50b) (hereinafter, when steamed alone is referred to as the steamed rice 50a and the protrusion 51a, respectively) is formed along the side end A transport member 230 is provided. It goes without saying that the respective members or elements constituting these lifting and lowering mechanisms are also provided at the opposite side end across the steam 50a.

  The spring 170 is fitted on the lower end side of the lift bar 160, and both ends thereof are locked by a ring or cap-like locking tool 240 while the drop from the lift bar 160 is prevented.

  The engagement plate 180 is inserted and attached to the bearing holder 225 through which the support rod 220 is inserted at the proximal end side, and the elevating rod 160 is inserted at the distal end side. With this configuration, when the spring 170 ascends along with the ascent of the lift bar 160, the top side of the spring 170 engages with the engagement plate 180 via the abutment of the locking tool 240, and the spring 170 further ascends. Is supposed to be blocked.

  The gear member 190 is housed in a box-shaped case 191 with a pair of upper and lower pinions 192 a and 192 b engaged with each other, as shown in FIG. Penetrate in the longitudinal direction. Although not visible in FIG. 13, the lift bar 160 engages with both the pinions 192a and 192b so as to function as a so-called rack and pinion rack. Further, in the gear member 190, the pivoting rod 200 penetrates so that the width direction of the case 191 and the surface direction of the upper pinion 192a are orthogonal to the elevating rod 160.

  The second spring 250 as the other biasing member is locked by the case 191 and the locking tool 260 at the portion of the elevating rod 160 which protrudes from the case 191, and similarly to the spring 170, the second spring 250 is prevented from falling off. It is fitted as it is.

  The pivoting rod 200 is formed about the length between the protrusions 51a and 51a at the steam 50a side end, and the top plate 210 is attached to both ends in a rotatable state together with the pivoting rod 200.

  Next, the lifting and lowering operation of the container by the lifting and lowering mechanism of the second embodiment will be described. FIG. 14 is a photograph showing the state of the spring 170 before the start of the elevation operation, FIG. 15 is a photograph showing the state of the top plate 210, FIG. 16 is a photograph showing the state of the spring 170 during the elevation operation, FIG. It is a photograph which shows the state of 210.

  Before raising the steam, the spring 170 is in the extended state as shown in FIG. 14, and the top plate 210 is in the state where the tip is facing upward, ie, in the vertical direction, as shown in FIG. It is in the state of facing.

  When the chain gear 100 starts to rotate, the balance plate 90 and the support bar 220 rise, and the lift bar 160 rises accordingly. Here, since the bearing holder 225 is fixed, the engaging plate 180 attached thereto does not rise either. Therefore, although the spring 170 rises to the position of the engagement plate 180 as the elevation rod 160 rises, the spring 170 is engaged with the engagement plate 180 via the abutment of the top side stopper 240 to prevent further elevation. Ru. On the other hand, since the lift bar 160 continues to ascend, the spring 170 is contracted against the biasing force as shown in FIG.

  On the other hand, as shown in FIG. 17, the pivoting rod 220 ascends with the elevation of the elevating rod 160, and becomes higher than the protrusion 51a of the steam 50a. At the same time, when the spring 170 is contracted from the state shown in FIG. 14 to the state shown in FIG. 16, elastic energy as its biasing force is transmitted to the pinions 192 a and 192 b of the gear member 190 via the elevating rod 160. As they rotate. The top plate 210 turns so as to turn in the horizontal direction with the turning of the turning rod 200, and after facing the protrusion 51b of the second stage of steaming 50b from the bottom, the turning rod 200 is further slightly raised. By this, as shown in FIG. 17, it abuts on the bottom of the protrusion 51b.

  Here, when the pivoting rod 200 is pivoted, the second spring 250 is compressed against the biasing force in the same manner as the spring 170, as shown in FIG. 17, through the upper pinion 192a. That is, the spring 170 has elastic energy which can be turned until the top plate 210 is turned from the vertical direction to the horizontal direction through the gear member 190, and the second spring 250 has elastic energy which can absorb it. You need to have a similar stroke.

  Subsequently, if the top plate 210 abuts against the projection 51b, the lift rod 160 and the pivoting rod 200 rise with the further rise of the support rod 220 while maintaining this state, and the top plate 210 from below. The second stage steam 50b is supported in a state where a gap is formed between the second stage steam 50b and the lower stage steam 50a, whereby the lowest stage steam 50a can be moved in the horizontal direction. FIG. 17 shows a state in which the top plate 210 has already been slightly raised after coming into contact with the protrusion 51 b.

  After moving the lowermost steamer 50a, when moving down the steamer 50b, the top plate 210 comes into contact with the projection 51b as the elevating bar 160 and the pivoting bar 200 move down as the support bar 220 descends. While supporting steamer 50b in a state of being in contact, it is lowered to the lowest level.

  Subsequently, as the lift bar 160 further descends as the support bar 220 further descends, the pivot bar 200 similarly descends, and the top plate 210 separates from the protrusion 51 b of the steamer 50 b. When it has dropped so far, the engagement between the spring 170 and the engagement plate 180 is naturally released by gravity, and the spring 170 is extended by its elastic energy. Similarly, in the second spring 250 as well, elastic energy acts in the direction of gravity, and as the pinion 192a of the gear member 190 rotates by its action, the pivoting rod 200 pivots. At the same time, the top plate 210 pivots so as to turn in the vertical direction, and returns to the state before the elevating operation shown in FIG.

  As described above, the container lifting apparatus 151 of the second embodiment uses the elastic energy as the biasing force of the spring 170 and the second spring 250 to make the top plate 210 in contact with the protrusion 51 b of the vapor 50 b to be lifted and lowered. Since it was made to rotate, if it was a means to convey the urging | biasing force of the raising / lowering rod 160 and the spring 170 to a top plate, the steam 50b can be raised / lowered, and it becomes possible to simplify a raising / lowering mechanism.

  In the second embodiment, the material of each member is not particularly limited as long as it can be applied. For example, as the top plate 210, a plastic other than an inexpensive metal such as stainless steel can be suitably used. . The case 191 of the gear member 190 is preferably plastic because it is easy to process and can be colored, and nylon is particularly preferable because it is high in strength. Furthermore, for example, a member for improving the design, such as covering the second spring 250 with a cap, covering the entire elevating mechanism with a cover as in the first embodiment, or the like may be added as appropriate.

  Next, the transport member 230 will be described. Fig. 18 is a photograph showing the container conveyance member, Fig. 19 is a photograph taken from above of the sliding member provided in the container conveyance member, Fig. 20 is a photograph taken from the side of it, and Fig. 21 is a conveyance direction of the container guide of the sliding member. Is a photograph showing a state in which the steam is engaged from the opposite direction.

  As shown in FIG. 18, the conveying member 230 mainly includes a rail 270 extending along the side end of the steam 50a and a sliding body 280 sliding thereon.

  The rail 270 has a chain 271 attached thereto. The lower half of the chain 271 is inserted into the rail 270 while the upper half is provided above the rail 270 along the extending direction of the rail 270 and wound around the rail 270. Thus, it can rotate along the rail 270.

  As shown in FIGS. 19 and 20, the sliding body 280 is a case 281 made of plastic in this example, a pinion 282 inside the case 281, and a rod-shaped container guide inserted in the radial direction of the pinion 282. 283 and mainly.

  The case 281 opens in a concave shape on either side of the upper and lower ends, and the front face is formed in an H shape, and is inserted over the opening 284 a on the lower end side and straddled on the rail 270. Further, at the opening 284 b on the upper end side, the pinion 282 is exposed, and the container guide 283 protrudes from the pinion 282. The chain 271 is inserted into the central portion 284c of the case 281 along the extending direction of the rail 270, whereby the container guide 280 slides on the rail 270 as the chain 271 pivots. . That is, the chain 271 and the pinion 282 constitute a so-called rack and pinion configuration.

  Further, a spring 290 as an urging member is fitted to the chain 271 so that both ends thereof are locked by the locking tool 300 and the case 281 so that unintended rocking is prevented, and the sliding body 280 When sliding, it moves adjacent to the sliding body 280.

  When the sliding body 280 slides, the container guide 283 moves in the direction of the arrow in the example of FIG. 20 together with the spring 290 and then engages with the projection 51a of the steam 50a shown in FIG. Then, the sliding body 280 further slides on the rail 270 to maintain the container guide 283 and the projection 51 a engaged with each other, that is, press the steaming 50 a through the projection 51 a by the container guide 283. The steam 50a is to be transported. The container guide 283 may be connected to a container guide 283 on the opposite side end of the steam 50a by a rod or the like, and the steam may be conveyed by pushing the steam 50a with this rod.

  Further, as shown in FIG. 21, the transport member 230 transports the steam 50a, for example, the next steam 50b has already been lowered to the lowermost position, even before the sliding body 280 returns to the initial position, as shown in FIG. The container guide 283 contacts the projection 51b of the steam 50b and rotates in the horizontal direction, so that it can slide under the projection 51b and slide back on the rail 270 to the original position. The container guide 283 turns vertically after being under the protrusion 51b, and returns to the original state as shown in FIG. That is, when the container guide 283 rotates against the projection 51b in the return direction of the sliding body 280 (in the direction opposite to the conveying direction of the steam), the pinion 282 shown in FIG. Shrink against. In this state, when the container guide 283 descends below the protrusion 51 b and disengaged, the elastic energy of the spring 290 causes the pinion 282 to reversely rotate, and the container guide 283 rotates and returns to the original state.

  As described above, the transfer member 230 is provided at the side end of the steamer 50a where the protrusion 51a is formed, whereby the installation space and the number of members can be saved or simplified. In addition, by rotating the container guide 283 in the reverse direction by the biasing force of the spring 290, the sliding body 280 can be returned to the original position even in the state where the vapor is placed on the apparatus, which allows for ad hoc use. .

  The transport member 230 may also be attached to another container lifting device as a transport device, similarly to the transport member 30 described in the first embodiment. Further, also in the container lifting and lowering apparatus 151 of the second embodiment, the transport member 30 described in the first embodiment may be attached instead of the transport member 230. Furthermore, in the transport member 30 of the first embodiment, the container drawer 120 and the member provided for sliding may be used together with the transport member 230.
