JP 2002-113292 A

  In recent years, contractors collect and wash laundry for hospitalized patients. For this reason, if it is a big hospital, a lot of laundry will generate | occur | produce. In this case, if there is only a lot of laundry, there is no problem if a large washing machine is used and a large dryer is used. However, it is not preferable to mix laundry of hospitalized patients with each other, and since it is impractical to sort later when they are mixed, it is necessary to wash and dry as laundry unit F collected in hospitalized patients. There is. Cannot be washed and dried together.

  When the laundry of the hospitalized patient is washed together in the washing unit F, if the laundry is put in the net bag and used as the washing unit F, the laundry is no longer mixed, so there is no problem. However, it is difficult to dry the laundry in the net bag, and the laundry must be taken out of the net bag and dried. If the dryer can dry only one washing unit F at a time, even if a large amount of washing units F in which the laundry is put in a net bag can be washed together, the dryer will eventually be dried at the stage of drying. The washing unit F can be dried only by the number. This takes too much time and effort and is not realistic.

  Here, the continuous dryer disclosed in Patent Document 1 includes a preliminary dryer and a main dryer, and pays attention to the point that two washing units F are sequentially dried without being mixed, for example, the preliminary dryer or the main dryer. It is conceivable to construct a continuous dryer that increases the number of dryers and sequentially dries more washing units F without mixing them. However, a continuous dryer in which a large number of preliminary dryers and a main dryer are inclined together is not practical and has the following problems.

  First, there is a problem in that the time for taking out or transferring the washing unit F increases and the time required for drying increases. A continuous dryer having a structure in which a large number of pre-dryers and main dryers are inclined integrally, and the final main drying is performed by inclining the pre-dryers and main dryers integrally and rolling the washing unit F from upper to lower. The washing unit F is taken out from the machine, or the washing unit F is transferred from the preliminary dryer to the main dryer. That is, in order to take out or transfer the washing unit F, it is necessary to incline the preliminary dryer and the main dryer integrally, and it takes time to operate the inclination mechanism. Further, in order to transfer the washing unit F so as not to be mixed, it is necessary to sequentially open and close the intermediate doors that serve as boundaries between a large number of preliminary dryers and the main dryer, and it takes time to open and close the intermediate doors.

  Further, there is a question as to whether the laundry taken out from the net bag can be properly transferred from the preliminary dryer to the main dryer as the washing unit F. The continuous dryer that transfers the washing unit F from the pre-dryer to the main dryer by tilting the pre-dryer and the main dryer integrally and rolling the washing unit F from the upper to the lower is the pre-dryer and the main dryer. There is a possibility that the washing unit F does not roll well depending on the inclination angle of the machine. In this regard, Patent Document 1 proposes measures such as vibrating the preliminary dryer and the main dryer (Patent Document 1 [0012] [0013]), but the number of the preliminary dryer and the main dryer is increased. If it is, it is difficult to vibrate the whole.

  The shortening of the time required for the operation of the tilting mechanism and the reliable transfer of the washing unit F can be realized, for example, by ignoring the manufacturing cost, so that a strong tilting mechanism can be constructed, or the preliminary dryer and the main dryer can be vibrated. It may be possible to solve it individually. However, the trouble of sequentially opening and closing the intermediate door so as not to mix the washing units F is not eliminated, and the time required for drying cannot be shortened. Thus, as long as patent document 1 is based, it cannot be set as the continuous dryer which dries in a short time, without mixing many washing units F. Therefore, in order for a hospital to collect and wash laundry for hospitalized inpatients, the laundry for each inpatient is used as a washing unit F, and a plurality of washing units F can be simultaneously dried without being mixed. Considered to develop.

As a result of the study, a continuous dryer in which a rotating drum having air permeability and water permeability is incorporated in a fixed drum, and the fixed drum is a cylinder that is n + 1 times the unit length W (n is an integer of 2 or more). The hot air drying means is provided on the side surface, the opening end can be opened and closed on the end face of the start end, and the discharge opening can be opened and closed on the end face of the end side, and the rotary drum is a cylinder of n times the unit length W. The drying chamber unit DC1 to the drying chamber unit DCn are formed by dividing the fixed drum in the extending direction by the unit length W, and the drying chamber unit DC1 to the drying chamber unit DCn are divided in half along the extending direction of the fixed drum. The fixed basket group composed of the fixed basket FC1 to the fixed basket FCn each having a width of the unit length W, and the movable basket group composed of the movable basket MC1 to the movable basket MCn each having a width of the unit length W. The fixed basket group brings the fixed basket FC1 close to the end face of the fixed drum. Fixed in position in the extending direction of the fixed drum, moving the car group, advanced position brought near the retracted position brought near the moving basket M C1 at the starting end side end face, the moving basket M Cn to the end-side end surface of the fixed drum of the fixed drum between, the unit is freely forward and backward by a length W in the extending direction of the fixed drum, stationary car group and moving the car group is rotatable integrally accordance parallel pivots to the extending direction of the fixed drum In the configuration, the washing unit F is made up of the fixed basket FC1 and the movable basket MC1 by moving the movable basket group forward and lowering the fixed basket group and entering the fixed basket FC1 through the inlet and moving the movable basket group backward. Put into the room unit DC1, move the moving basket group downward and move the moving basket group downward, move the fixed basket group downward to move the moving basket MC1 to the fixed basket FC2, and move the moving basket group backward to move the fixed basket FC2 and move Transfer to the drying chamber unit DC2 consisting of the basket MC2 By repeating the order, the units are sequentially transferred from the drying chamber unit DC1 to the drying chamber unit DCn, moved to the moving basket MCn with the moving basket group down, and then the moving basket group moved forward to bring the fixed basket group down. Developed a continuous dryer characterized in that the opening of the movable basket MCn brought close to the end side end face is dropped downward and taken out from the discharge port on the end side end face . The washing unit F includes, for example, laundry in units of hospitalized patients, and net bags used for washing.

  The continuous dryer according to the present invention moves the moving basket group forward and backward with respect to the fixed basket group, and sequentially mixes the washing unit F fed into the drying room unit DC1 from the inlet into the other drying unit F without mixing with the other washing units F. It is dried while being transferred from DC2 to the drying chamber unit DCn, and is finally taken out from the drying chamber unit DCn through the discharge port in a state where the drying is finished. This is because the moving basket group can move forward and backward within the fixed drum longer than the rotary drum by the unit length W, and further, the movement of the fixed basket FC1 to the fixed basket FCn and the movable basket MC1 to the movable basket MCn. This is the effect of making the width in the advancing and retreating direction of the cage group, that is, the width in the extending direction of the fixed drum, all the unit length W. Specifically, the washing unit F is put into the drying chamber unit DC1 as follows, the washing unit F is transferred from the previous drying chamber unit DC1 to the subsequent drying chamber unit DC2, and the washing unit F is moved to the last drying chamber. Taken from the unit DCn.

  First, the laundry unit F to be dried advances the moving basket group, and rotates the rotating drum in less than one rotation while facing the fixed basket FC2 to the fixed basket FCn and the moving basket MC1 to the moving basket MCn-1. With the fixed basket group facing down, enter the fixed basket FC1 through the inlet on the end face side. Here, at the stage where the washing unit F is inserted, the fixed basket FC1 is positioned below, so that the insertion port is preferably provided above the end surface on the start end side. Then, this time, the movable basket group is moved backward to face the fixed basket FC1 to the fixed basket FCn and the movable basket MC1 to the movable basket MCn, thereby washing in the drying room unit DC1 composed of the fixed basket FC1 and the movable basket MC1. Unit F can be input (more precisely, the washing unit F is confined in the drying chamber unit DC1).

  The washing unit F put into the drying chamber unit DC1 is dried by the hot air from the hot air drying means while continuously rotating the rotary drum. After a predetermined processing time elapses, the continuous rotation of the rotating drum is stopped, and the rotating basket is rotated by rotating the rotating drum less than one rotation while facing the fixed basket FC1 to the fixed basket FCn and the moving basket MC1 to the moving basket MCn. Down. At this time, the washing unit F put into the drying chamber unit DC1 is in the moving basket MC1.

  Here, after the moving basket group is moved forward, this time, when the rotating drum is rotated by less than one rotation and the fixed basket group is lowered, the fixed basket FC2 to the fixed basket FCn and the movable basket MC1 to the movable basket MCn-1 are moved. The washing unit F moves from the moving basket MC1 to the fixed basket FC2. Then, when the movable basket group is moved backward again to face the fixed basket FC1 to the fixed basket FCn and the movable basket MC1 to the movable basket MCn, the washing unit F previously put into the drying chamber unit DC1 is moved to the fixed basket FC2 and the movable basket FC1. It is transferred to the drying chamber unit DC2 composed of the basket MC2.

  The washing unit F, which is sequentially transferred toward the drying chamber unit DC1 to the drying chamber unit DCn while being dried as described above, is taken out from the moving basket unit MCn viewed through the discharge port. When the continuous rotation of the rotating drum is stopped, the rotating drum is rotated by less than one rotation with the fixed basket FC1 to the fixed basket FCn and the moving basket MC1 to the moving basket MCn facing each other, and the moving basket group is lowered, the drying chamber The washing unit F stored in the unit DCn moves to the moving basket MCn. Then, when the moving basket group is moved forward, the rotating drum is rotated again by less than one rotation and the fixed basket group is lowered, the fixed basket FC2 to the fixed basket FCn and the moving basket MC1 to the moving basket MCn-1 face each other. The opening of the moving basket MCn brought close to the end face is exposed downward. As a result, the washing unit F that has moved to the movable basket MCn falls from the movable basket MCn and can be taken out from the discharge port on the end surface on the end side. From this, in order to smoothly take out the washing unit F, the rotating drum is discharged in a downward gradient with the fixed basket FCn opened upward between the fixed basket FCn of the fixed basket group and the end side end surface of the fixed drum. A slope should be provided. Moreover, since the washing unit F falls from the upper side to the lower side, the discharge port may be provided below the end surface on the end side.

  The rotating drum is made of punched metal, expanded metal or net body with air permeability and water permeability, but in order to maintain the temperature difference of the hot air sent from the drying chamber unit DC1 to the drying chamber unit DCn, the partition plate is It is good to comprise by the face material which does not provide air permeability or water permeability. The washing unit F is stored in the drying chamber unit DC1 to the drying chamber unit DCn of the rotary drum, and is dried while being stirred according to the rotation of the rotary drum while receiving the warm air sent into the fixed drum by the hot air drying means. . The hot air drying means is configured as a set of a heater and a suction fan, similarly to a conventional dryer of the same type. The hot air drying means is preferably provided with n groups corresponding to the drying chamber unit DC1 to the drying chamber unit DCn, but the drying chamber unit DC1 to the drying chamber unit DCn communicate with each other by the air permeability. One hot air drying means may be provided for each of the plurality of drying chamber units DC1, DC2.

  The rotating drum is incorporated in the fixed drum so that the fixed basket group and the movable basket group are rotated integrally with each other, and the movable basket group is advanced and retracted in the extending direction of the fixed drum with respect to the fixed basket group. A fixed cage group is attached to the end side rotating ring and the starting end side rotating ring that rotate in a plane parallel to the extending orthogonal direction, and along the guide bar for the moving cage group that spans the terminal side rotating ring and the starting end side rotating ring. It is preferable that the moving basket group is attached in such a manner that it can freely move forward and backward. For example, the rotary drum directly supports the fixed cage group with respect to the terminal-side rotary ring and the start-side rotary ring, and also moves with respect to the terminal-side rotary ring and the start-side rotary ring via the moving cage group guide bar. The group is indirectly supported, and the fixed cage group and the movable cage group are integrally rotated according to the rotation of the terminal side rotation ring and the start end side rotation ring.

  Further, the rotary drum allows the movable basket group to advance and retreat along the guide cage for the movable cage group that spans the terminal-side rotary ring and the start-side rotary ring. Therefore, the terminal-side rotary ring and the start-side rotary ring The moving cage group can be advanced and retracted in the extending direction of the fixed drum with respect to the fixed cage group whose position is fixed at the position. As the moving and retracting means of the moving car group along the moving car group guide bar, various conventionally known driving means can be used. For example, an advancing and retracting linear cylinder that extends and retracts the rod in parallel with the moving car group guide bar is exemplified. be able to.

  Here, if the gap between the inner peripheral surface of the fixed drum and the outer peripheral surface of the rotating drum changes in size, the hot air is blown into a large portion of the gap and becomes difficult to flow into the rotating drum, and the washing unit F can be dried well. There is a risk of disappearing. Therefore, the specific fixed drum has a circular cross section, and the rotary drum has an outer peripheral surface close to the inner peripheral surface of the fixed drum (an outer peripheral surface surrounding each opening of the fixed basket FC1 to the fixed basket FCn and the movable basket MC1 to the movable basket MCn. It is preferable that the moving cage group guide bar is bridged between the terminal-side rotating ring and the starting-end rotating ring so as to be within the cross-sectional shape of the rotating drum. Thereby, the outer peripheral surface surrounding each opening of the fixed basket FC1 to the fixed basket FCn and the movable basket MC1 to the movable basket MCn constituting the drying chamber unit DC1 to the drying chamber unit DCn has a gap with the inner peripheral surface of the fixed drum as much as possible. It can be configured to be constant, and warm air can be allowed to flow into the rotating drum without creating a puddle.

  The continuous dryer of the present invention can dry a plurality of washing units F at the same time without being mixed, and for example, a laundry of a hospitalized patient in a hospital can be collected and washed. This halves the rotating drum that forms the drying chamber unit DC1 to the drying chamber unit DCn to form a fixed basket group composed of the fixed basket FC1 to the fixed basket FCn and a movable basket group composed of the movable basket MC1 to the movable basket MCn. This is an effect brought about by transferring the washing unit F from the drying chamber unit DC1 to the drying chamber unit DCn by moving the moving basket group forward and backward with respect to the fixed basket group. Further, the continuous dryer of the present invention does not need to drive the tilting mechanism to transfer the washing unit F or open / close the intermediate door, so that it takes a processing time in addition to drying the washing unit F. In addition, the present invention has an effect of realizing processing with a short drying time as a whole while handling a large number of washing units F.

  Furthermore, the continuous dryer of the present invention is a dryer that handles a plurality of selected units, and saves human work and is easy to automate. For example, if the dryer is provided with an inlet and outlet in each of the drying chamber unit DC1 to the drying chamber unit DCn formed on the rotating drum, the drying time applied to the drying chamber unit DC1 to the drying chamber unit DCn is equal, and the drying chamber unit It is necessary to put in and take out the washing unit F at the same time from the DC1 to the drying chamber unit DCn, and human work is required for each drying chamber unit DC1 to the drying chamber unit DCn. On the other hand, the continuous dryer of the present invention has only one insertion port and one discharge port for the washing unit F, so that human work is only required for the input port and the discharge port, and overall labor can be saved. . Since the human work is limited to one place each of the inlet and outlet, it can be easily automated if the human work is mechanized. As described above, the continuous dryer of the present invention has an effect of saving labor or automation as a dryer that handles a plurality of selection units.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The continuous dryer of this invention is comprised by incorporating the rotating drum 2 which has air permeability and water permeability in the fixed drum 1, as seen, for example in FIGS. The continuous dryer of this example has a unit length W (see FIG. 8) of 400 mm, and six drying room units DC1 to DC6 are formed, that is, a maximum of 6 washing units F at the same time. Can be dried. In the continuous dryer according to the present invention, any number of drying chamber units DCn (n is an integer of 2 or more) can be used. However, if n is too large, the transfer operation of the washing unit F becomes complicated and a large number of units are required. Since the efficiency of drying the washing unit F is decreased, n is 4 to 8, and preferably n is 5 to 7.

  The fixed drum 1 is a metal cylinder having an internal length (2800 mm in the above example) that is 7 times the unit length W start side. The heater 11 and the suction fan 12 constituting the hot air drying means are respectively connected to the upper duct. It is attached via 111 and the lower duct 121. The warm air drying means (heater 11 and suction fan 12) in this example is one for the drying chamber unit DC1, one for the drying chamber unit DC2 and the drying chamber unit DC3, one for the drying chamber unit DC4 and the drying chamber unit DC5. In addition, one unit is assigned to the drying chamber unit DC6, and an openable and closable intake port 112 that can take outside air into the heater 12 assigned to the drying chamber unit DC6 is provided. The air inlet 112 is opened when it is desired to send cold air to the washing unit F stored in the drying chamber unit DC6.

  The fixed drum 1 of this example is configured by joining a semi-cylindrical body obtained by halving a metal cylindrical body up and down with a flange provided at each end face and by bolting. In order to maintain the temperature difference of the hot air provided for each of the hot air drying means described above, a boundary plate 16 is provided on the inner peripheral surface of the fixed drum 1 to divide a gap with the outer peripheral surface of the rotating drum 2 in the radial direction, A reinforcing ring 161 is assembled to the boundary plate. A sliding block 232, a terminal side driving roller 241, a terminal side driven roller 242, a starting side driving roller 251, and a starting side driven roller 252 to be described later are opened from an opening provided in a section partitioned by the boundary plate 16 and the reinforcing ring 161. It is inserted into the inside of the fixed drum 1.

  The fixed drum 1 has a rectangular parallelepiped outer shape formed by assembling square pipes, and a front end face 131 and a terminal end face 141 attached to the front side and the rear side of the main body frame 15 and the front end face and the rear end face opened. The peripheral flanges are in contact with each other and bolted to be supported by the main body frame 15. The main body frame 15 is not shown in the figure, but a plate material is also attached to the side surface (a surface parallel to the paper surface in FIG. 1) to conceal the fixed drum 1 that becomes hot in the operation state from the outside. A drive motor 243 that rotates the rotating drum 2 and a forward / backward moving cylinder 231 that moves the moving basket group 22 forward / backward are housed between the fixed drum 1 and a plate attached to the side surface.

  As shown in FIG. 2, the insertion port 13 is opened above the start end side end surface 131 (more precisely, the upper half), and is moved up and down by an insertion port cylinder 133 that expands and contracts the rod downward. It can be opened and closed freely. Further, as shown in FIG. 7, the discharge port 14 is opened below the end-side end surface 141 (more precisely, the lower half), and is raised and lowered by a discharge port cylinder 143 that expands and contracts the rod upward. The shutter 142 can be opened and closed freely. Although raising / lowering of the inlet shutter 132 and the outlet cylinder 143 is automated, it may be a manual type in which the operator raises / lowers manually.

  The rotating drum 2 is a cylindrical body having an outer peripheral surface made of punching metal and having air permeability and water permeability, and has an inner length (2400 mm in the above example) that is 6 times the unit length W start side. Using the metal face material as partition plates 215 and 224, the drying chamber units DC1 to DC6 are formed by dividing the stationary drum 1 by the unit length W in the extending direction of the fixed drum 1, and the drying chamber units DC1 to DC6 are further extended in the extending direction of the fixed drum 1. A half-cylinder fixed basket group 21 consisting of fixed baskets FC1 to FC6 each having a width of unit length W, and moving baskets MC1 to MC6 each having a width of unit length W. And a semi-cylindrical movable cage group 22 made of Similarly to the partition plates 215 and 224, the side surfaces of the fixed cage FC1 and the movable cage MC1 facing the start end side surface 131 and the side surfaces of the fixed cage FC6 and the movable cage MC6 facing the end side end surface 141 are also made of a metal surface material. .

  The fixed basket group 21 and the movable basket group 22 of this example are substantially the same shape, and the fixed basket group concave groove 212 and the movable basket group concave groove through which the later-described movable basket group guide bar 244 and fixed basket group guide bar 245 pass. Except 222, it is a semi-cylindrical cage having a semi-circular front view (see FIGS. 2 to 6) whose width is equal to the unit length W. The trapezoidal ribs 214 and 223 having a trapezoidal cross section are attached to the inner periphery of each opening of the fixed basket FC1 to the fixed basket FC6 and the movable basket MC1 to the movable basket MC6 in order to ensure shape retention of the opening and smooth movement of the washing unit F. (In FIG. 1, the rotating drum 2 is not broken, and the ribs 214 and 223 are not visible. For convenience of illustration, punching metal holes appearing on the outer peripheral surface of the rotating drum 2 are not shown in FIG. 1. ).

  The fixed basket group 21 is provided with a discharge slope 211 having a downward slope with the fixed basket FC6 opened upward between the fixed basket FC6 and the terminal end surface 141 (see FIG. 1). The discharge slope 211 rotates integrally with the fixed basket group 21. Further, the fixed basket group 21 of this example is provided with a detection plate 213 at a position close to the lower end of the discharge slope 211, that is, the end side end surface 141, and is fixed by upper and lower proximity sensors 153 and 154 provided on the end side end surface 141. Whether the basket group 21 is in the upper stage or the lower stage can be detected (see FIG. 7). As a result, the rotating drum 2 rotated for drying can be stopped by determining whether the fixed basket group 21 is set to the upper stage or the lower stage, and the stopped drying drum 2 can be turned 180 if necessary. It is also possible to reverse the vertical relationship between the fixed basket group 21 and the movable basket group 22 by rotating it by a degree.

  The rotary drum 2 moves the fixed basket FC1 toward the start end side end face 131 to fix the position of the fixed basket group 21 in the extending direction of the fixed drum 1, and moves the moving basket FC1 toward the start end end face 131 and the end side end face. The fixed basket group 21 and the movable basket group 22 are fixed to the fixed drum 1 while the movable basket group 22 can move forward and backward by a unit length W in the extending direction of the fixed drum 1 between the forward movement position where the movable basket FC6 is brought close to 141. It is possible to rotate as a unit according to the center of rotation parallel to the extending direction. There are various possible configurations for realizing the forward and backward movement of the movable cage group 22 and the rotation of the fixed cage group 21 and the movable cage group 22 as one body. In this example, the starting end side driving roller 251 and the starting end side driven roller 252 rotate. The fixed basket group 21 is fixed in position, and the movable basket group 22 is supported by the movable basket group guide bar 245 installed on the start end side driving roller 251 and the start end side driven roller 252 so as to be able to advance and retract. .

  The end-side rotation ring 24 is placed across the end-side drive roller 241 and the end-side driven roller 242 supported by the main body frame 15. The end-side drive roller 241 and the end-side driven roller 242 are provided with guide plates on the side surfaces to prevent the end-side rotation ring 24 from departing. The start end side rotation ring 25 is placed across the start end side drive roller 251 and the start end side driven roller 252 supported by the main body frame 15. The start end side driving roller 251 and the start end side driven roller 252 are also provided with guide plates on the side surfaces to prevent the start end side rotating ring 25 from departing. Since the rotating drum 2 is very heavy, the terminal-side rotating ring 24 and the starting-end-side rotating ring 25 and the terminal-side driving roller 241, the terminal-side driven roller 242, the starting-end driving roller 251, and the starting-end driven roller 252 are in friction. When one of them rotates, the rest rotates with it.

  The end side drive roller 241 is connected to the drive motor 243 supported by the main body frame 15, and is connected to the start end side drive roller 251 by the drive transmission rod 253, and the drive transmission rod 253 and the start end side drive roller 251 are synchronized. The drive is rotated. The end-side driven roller 242 and the start-end side roller 252 are connected by a driven interlocking rod 254, and according to the rotation of the end-side rotation ring 24 and the start-end side rotation ring 25 according to the drive rotation of the drive transmission rod 253 and the start-end side drive roller 251. And follow-up rotation synchronously. As described above, the terminal-side rotating ring 24 and the starting-end side rotating ring 25 are engaged with the terminal-side driving roller 241, the terminal-side driven roller 242, the starting-end side driving roller 251, and the starting-end driven roller 252 by friction. Since the remainder rotates along with the rotation, for example, a pair of drive rollers may be arranged on the end side and a pair of driven rollers on the start side.

  The fixed basket group 21 is fixed in position to the end-side rotation ring 24 and the start-side rotation ring 25 with the fixed basket FC1 brought close to the start-side end surface 131. As a result, the fixed basket group 22 rotates in accordance with the end-side rotation ring 24 and the start-end side rotation ring 25 but is fixed in the extending direction of the fixed drum 1. The fixed basket group guide bar 244 has two fixed baskets on the start side drive roller 251 and the start side rotation ring 25 so as to fit in the fixed basket group concave groove 212 formed on the outer peripheral surface of the fixed basket group 21. A group guide bar 244 is stretched over, so that the start-end side drive roller 251 and the start-end side rotation ring 25 can rotate together. From this, the fixed basket group 21 may be fixed to the fixed basket group guide bar 244.

  The movable cage group 22 is bridged between the terminal-side rotary ring 24 and the start-side rotary ring 25 on a guide bar sliding block 221 that is fixed in a groove 222 for movable cage group formed on the outer peripheral surface. A movable basket group guide bar 245 is passed therethrough. The moving cage group guide bar 245 constitutes the advancing and retreating trajectory of the moving cage group 22 that advances and retreats, and, like the fixed cage group guide bar 244, fixes the positional relationship between the terminal side rotating ring 24 and the starting end side rotating ring 25, It also has the function of rotating together. In order to stably maintain the positional relationship of the four fixed cage group guide bars 244 and the movable cage group guide bar 245 spanned over the end side rotation ring 24 and the start end side rotation ring 25, for example, the end side rotation An intermediate ring may be provided between the ring 24 and the starting end side rotating ring 25 so as to pass through all of the fixed basket group guide bar 244 and the movable basket group guide bar 245.

  The moving basket group 22 of this example further has an advancing / retreating ring 23 attached to the end face of the moving basket MC6. The forward / backward direct acting cylinder 231 fixed to the cylinder support flange 151 provided on the main body frame 15 allows the forward / backward movement ring 23 to be slidable by a U-shaped resin ring sliding block 232 provided at the rod end. I'm holding it. The sliding block 232 can move forward and backward along a slider 152 fixed to the cylinder support flange 151 (see FIG. 1). As a result, the moving cage group 21 rotates in accordance with the end-side rotation ring 24 and the start-side rotation ring 25, but when the advancing / retracting linear cylinder 231 expands / contracts the rod, the advancing / retreating ring 23 is pushed and pulled, and the fixed drum 1 Advance and retreat in the extending direction.

  The rotating drum 2 of this example rotates at the end side so that the fixed basket group guide bar 244 and the movable basket group guide bar 245 are all received in the fixed basket group concave groove 212 and the movable basket group concave groove 222. It is spanned between the ring 24 and the starting end side rotating ring 25. In addition, the forward / backward direct acting cylinder 23 only rotates the ring sliding block 232 provided at the rod end, and the terminal side driving roller 241, the terminal side driven roller 242, the starting side driving roller 251, and the starting side driven roller 252 rotate on the terminal side. As long as it engages with the ring 24 and the starting end side rotating ring 25 by friction, it is inserted into the fixed drum 1 within the area surrounded by the boundary plate 16 and the reinforcing ring 161, respectively. As a result, the gap between the inner peripheral surface of the fixed drum 1 and the outer peripheral surface of the rotary drum 2 is configured to be constant, and warm air from the heater 11 to the suction fan 12 is allowed to flow into the rotary drum 2 without waste.

  Next, a procedure for drying a large number of washing units F by the continuous dryer of this example will be described from a state in which the washing unit F is not contained in all the drying room units DC1 to DC6. First, as shown in FIG. 8, the lower proximity sensor 154 detects the detection plate 213, so that the fixed basket group 21 of the rotating drum 2 is down and the movable basket group 22 is in the upper stage. The rod of the moving cylinder 231 is extended and the moving cage group 22 is advanced by pushing the advancing / retracting ring by the ring sliding block 232 moved to the end side, and the fixed basket FC2 to the fixed basket FC6 and the movable basket MC1 to the movable basket The fixed basket FC1 can be seen from above, facing the MC5.

  From the state in which the washing unit F can be put in this manner, the rod of the inlet direct acting cylinder 133 is extended to lower the inlet shutter 132 and the inlet 13 above the starting end surface 131 is opened. The laundry unit F to be dried is put into the fixed basket FC1. As shown in FIG. 9, the rod of the direct acting cylinder for inlet port 133 is shortened to raise the shutter 132 for inlet and close the inlet 13, and then the rod of the linear cylinder 231 for advancing and retracting is moved. The moving cage group 22 is retracted by pulling the advancing and retreating ring with the ring sliding block 232 that has been shortened and moved to the starting end side, and is opposed to the fixed basket FC1 to the fixed basket FC6 and the movable basket MC1 to the movable basket MC6. The washing unit F is confined in the drying chamber unit DC1 composed of the fixed basket FC1 and the movable basket MC1.

  The washing unit F confined in the drying chamber unit DC1 is dried by hot air from the hot air drying means (hot air from the heater 11 to the suction fan 12) while continuously rotating the rotary drum 2. After a predetermined processing time has elapsed, as shown in FIG. 10, by moving the rotating basket 2 downward with the moving basket group 22 down, the washing unit F confined in the drying chamber unit DC1 is moved to the moving basket MC1. I'll send it to you. In the drying drum 2 of this example, the upper proximity sensor 153 detects the detection plate 213 provided on the discharge slope 211, so that the moving basket group 22 is turned down when the rotation is stopped. In addition, for example, after the rotating drum 2 is stopped at an arbitrary rotation position, the rotating drum 2 is rotated by less than one rotation until the detection plate 213 is detected by the lower proximity sensor 153, so that the movable basket group 22 is lowered. May be.

  After the washing unit F is moved to the moving basket MC1, as shown in FIG. 11, the rod of the forward / backward direct acting cylinder 231 is extended and the forward / backward ring is pushed by the ring sliding block 232 moved to the end side. FIG. 12 shows the case where the movable basket group 22 is moved forward by rotating the rotating drum 2 at 180 degrees and the fixed basket group 21 is moved down until the detection plate 213 is detected by the lower proximity sensor 154. As described above, the fixed baskets FC2 to FC6 and the movable baskets MC1 to MC5 face each other, and the washing unit F moves from the movable basket MC1 to the fixed basket FC2. This is because the washing unit F has been transferred to the drying chamber unit DC2 composed of the fixed basket FC2 and the movable basket MC2 if the movable basket group 22 is moved backward and the fixed basket FC2 and the movable basket MC2 are opposed to each other. Is the same. Thus, the washing unit F is transferred from the drying chamber unit DC1 to the drying chamber unit DC6.

  At this time, the movable basket MC1 is detached from the fixed basket FC1, and the fixed basket FC1 can be viewed with the opening facing upward. Since the actual work is to dry a large number of washing units F in sequence, as shown in FIG. 13, the rod of the inlet direct acting cylinder 133 is extended and the inlet shutter 132 is lowered as described above. After the opening 13 above the starting end side end face 131 is opened, the next washing unit F to be dried is put into the fixed basket FC1. As described above, the feature of the continuous dryer of the present invention is that the transfer of the washing unit F and the introduction of the next washing unit F proceed at the same time and work can be done without waste.

  By repeating the procedure up to the above, as shown in FIG. 14, the washing unit F is added to all the drying room units DC1 to DC6 composed of the fixed basket FC1 to the fixed basket FC6 and the moving basket MC1 to the moving basket MC6. Will be dressed. As shown in FIG. 15, the continuous rotation of the rotary drum 2 is stopped with the moving basket group 22 facing down, and the washing units F confined in the drying chamber units DC1 to DC6 are moved to the moving baskets MC1 to MC1. Moving to the moving basket MC6, the moving basket group 22 is advanced. This means that the movable basket MC6 protrudes opposite to the discharge slope 211 attached to the upper fixed drum group 21.

  From here, the rod of the direct acting cylinder 143 for the discharge port is shortened to lower the discharge port shutter 142 and the discharge port 14 below the terminal end face 141 is opened, and then the lower proximity sensor 153 detects the detection plate 213. Rotate the rotating drum 2 by 180 degrees until the movable basket group 22 is changed to the upper stage and the fixed basket group 21 is changed to the lower stage. As shown in FIG. 16, washing is performed from the movable basket MC6 toward the discharge slope 211. The washing unit F, which has fallen off the discharge slope 211 due to the unit F falling, can be taken out from the discharge port 14. As described above, when the movable basket group 22 in the upper stage is advanced, the fixed basket FC1 can be seen from above, so that when the input port 13 is opened at the same time, the washing unit that has finished drying At the same time as taking out F, a new washing unit F can be put into the fixed basket FC1.
