Description

  The present invention relates to an apparatus for changing the order of transporting objects to be transported while being suspended on a hanger, for example, clothing. More specifically, the present invention relates to an apparatus for rearranging objects to be transported that rearranges objects to be transported randomly (irregularly) in a desired order.

  For example, in the clothing industry and the cleaning industry, clothes (conveyed objects) hung on hangers are lined up and conveyed to a predetermined processing position by a conveyor. In a cleaning factory or the like, an operation for sorting a large amount of processed clothing for each cleaning agency is performed. For this purpose, each garment is managed with a bar code on which predetermined information is recorded and a non-contact IC tag (collectively referred to as a tag).

  However, it is hard work to check the clothes that have been transported irregularly, for example, at each cleaning agency, remove the hangers from which the clothes are suspended, and rehang them at other positions. It takes time. Therefore, Patent Document 1 proposes a method and apparatus relating to clothing rearrangement in relation to this.

  In the technique proposed in Patent Document 1, first, an order number attached to a hanger on which clothes to be rearranged are read, and the read and supplied hangers are sequentially distributed to a plurality of circle conveyors. The distributed hangers are respectively supplied in the order of the permutation numbers attached to the engaging portions of the circle conveyor, and all the hangers are supplied to the circle conveyor. Thereafter, hangers are taken out from the respective circle conveyors in the preset order of the permutation numbers and supplied to the corresponding buffer units. Finally, the hangers are discharged and rearranged in the order of the order number read from the plurality of buffer units.

  In the technique proposed in Patent Document 1, a plurality of circle conveyors are arranged in order to rearrange irregularly arranged hangers (that is, hangers that suspend articles to be conveyed). Moreover, all the hangers are once supplied to one of the circle conveyors, and the state which temporarily places in a circle conveyor is formed. Therefore, since the device of Patent Document 1 includes a plurality of units, the entire device becomes large. In addition, it takes a long time to complete the rearrangement of all hangers because all hangers are supplied to the circle conveyor once, and the hangers are temporarily placed in the circle conveyor and removed one by one. Become.

  Further, the apparatus of Patent Document 1 is designed to perform batch processing for processing a predetermined amount (for example, 100) of objects to be conveyed at a time. Therefore, since the apparatus of Patent Document 1 starts processing after waiting for a certain amount of objects to be conveyed to accumulate, there is also a problem that it takes time.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rearrangement device for transported objects that can sequentially process the transported objects that are transported continuously and can shorten the processing time. .

  The above object is an apparatus for rearranging the transport order of the objects to be transported suspended on the hangers, and a plurality of carriers having receiving portions on which the hangers are hung, and the carriers arranged adjacent to each other And a carrier means for conveying the carrier in a predetermined conveyance direction, each of the carriers is detachable from the carrier means, and some of the carriers are removed from the adjacently arranged carriers. In some cases, this can be achieved by a rearrangement device of the objects to be transported formed so as to fill the removed space of the removed carrier with another carrier.

  According to the present invention, the object to be transported suspended on the hanger is transported using the carrier that is detachable from the transporting means. The carrier is easily removed from the conveying means and moved to another position, thereby changing the conveyance order of the objects to be conveyed. The space of the removed carrier is filled with the remaining carrier. Since the carriers on which the objects to be rearranged are placed in this way are sequentially removed and the space is filled, continuous processing can be performed even if the objects to be conveyed are supplied continuously. Since it is not necessary to provide a waiting time as in the case of batch processing in which rearrangement processing is performed after a certain amount of objects to be conveyed is accumulated, the processing time can be shortened according to the present invention.

  And if it further comprises a carrier transfer means for removing a part of the adjacently arranged carriers from the conveying means and attaching it to another position of the conveying means, the objects to be conveyed can be rearranged automatically. become. Moreover, it is preferable to further include a carrier stop mechanism for stopping the carrier at a desired position.

  The carrier transfer means preferably further comprises push-back means for pushing back the carrier located upstream from the carrier to be removed when the carrier is removed from the transport means. . When the push-back means is provided in this way, the carrier can be reliably transferred by the carrier transfer means.

  Moreover, it is desirable to further include an adhesion confirmation mechanism for confirming that the adjacently arranged carriers are adhered to each other. When the adhesion confirmation mechanism is provided in this way, it can be confirmed that the carrier is being conveyed normally.

  And the said conveyance means is a conveyor, The 1st surface on the said conveyor side and the 2nd surface on the said carrier side mutually contact, The conveyance force of the said conveyor is the said 1st surface and the said It can be set as the structure currently transmitted to each of the said carrier based on the frictional force which arises between 2nd surfaces.

  Also, information reading means for reading the information on the tag attached to each of the objects to be conveyed, instruction input means for inputting an instruction to rearrange the objects to be conveyed, signals from the instruction input means and the information reading means It is good also as a to-be-conveyed object rearrangement apparatus further containing the control means which controls the said conveyance means and the said carrier transfer means based on the signal from, and rearranges the said to-be-conveyed object.

  As described above, according to the present invention, the hanger is hung on the carrier that is detachable from the conveying means. When the carrier is removed, the remaining carriers are packed to fill the space so that continuous processing is possible. By performing continuous processing, processing time can be shortened. The removed carrier can be rearranged by moving it to another position together with the hanger.

  Hereinafter, a rearrangement device for transported objects according to an embodiment of the present invention will be described with reference to the drawings. Here, as an example, a rearrangement device in the case where clothing is a transported object will be described. FIG. 1 is a block diagram showing the overall configuration of the rearrangement device 1. The rearrangement device 1 includes a transport device 2 as a transport unit, a cutting device 3 that cuts out the hangers H on which clothes W are suspended at a predetermined position (work set station) of the transport device 2, one by one. The tag information reading device 4 as information reading means for reading management information from the tag TG attached to the garment W before the hanger H is cut out by the device 3, the instruction input device 5 for inputting an instruction to rearrange the garment W, and the conveyance A transfer device 6 as a transfer means for moving the position of the hanger H to be transported by the device 2 and a payout device 7 for paying out the rearranged hanger H from a predetermined position (dispensing station) of the transport device 2 are provided. Yes. The transport device 2 is rotationally driven in the CW direction by a drive device 21 having a drive motor (not shown).

  The driving device 21 of the transport device 2 and the devices 3 to 7 are controlled by a control device 8 that is configured around a computer. In particular, the control device 8 identifies the hanger H that is hanging the clothes W designated by the instruction input device 5 based on the management information from the tag information reading device 4, and drives the transfer device 6 to select the hanger H. Perform the sort operation. Below, each part structure with which the clothing rearrangement apparatus 1 is provided is demonstrated in detail.

  A carrier 10 that is detachable with respect to the transport device 2 is disposed adjacent to the line so as to surround a peripheral portion of the transport device 2. The carrier 10 receives the driving force of the transport device 2 and is transported in the arrow CW direction. FIG. 2 is a diagram showing the rearrangement device 1 as viewed in the direction of the arrow X in FIG. On the support member 23 fixed to the frame 22 of the transport device 2, a pair of conveyor support members 24, 24 rises at an interval. These conveyor support members 24, 24 extend in a direction perpendicular to the paper surface of FIG. 2 (the left-right direction in FIG. 1) and are connected by arc portions at both ends. That is, the conveyor support member 24 shown in FIG. 2 is formed in a loop shape as a whole (see FIG. 1). An endless conveyor 25 is provided on the outer periphery of the conveyor support member 24. The conveyor 25 is movably supported by the conveyor support member 24 and is designed to receive a driving force from the driving device 21 and rotate in a predetermined direction (see CW in FIG. 1).

  Further, the carrier 10 is engaged with the conveyor support member 24 so as to protrude to the outer periphery. The conveyor support member 24 also functions as a rail that guides the carrier 10 in the conveyance direction (CW direction). Although this point will be described in detail later, the carrier 10 receives a conveying force by contacting the conveyor 25 and moves along the conveyor support member 24.

  In FIG. 2, a hanger H in which a garment W is suspended is hung on the left carrier 10. The carrier 10 on the left side in FIG. 2 is the sending side. The carrier 10 on the right side is an empty carrier 10 that has been returned after being used for clothing sorting. In the rearrangement device 1, the carriers 10 in the state shown on the left side of FIG. 2 form a state in which the carriers 10 are adjacent to each other in the front-rear direction (see FIG. 1). Note that the return empty carrier 10 does not need to be in contact with another carrier 10. Each carrier 10 includes a receiving portion 10a, and a hook portion FK of the hanger H is hung on the receiving portion 10a.

  FIG. 3 is an enlarged view of the peripheral portion of the carrier 10. 4 is a diagram showing the state of the carrier 10 as viewed in the direction of arrow A in FIG. 3, and FIG. 5 is a diagram showing the state of the carrier 10 as viewed in the direction of arrow B in FIG. The relationship among the carrier 10, the conveyor support member 24, and the conveyor 25 will be described in more detail with reference to these drawings. As shown in FIG. 3, the main body 10M of the carrier 10 has a substantially crank-shaped cross section, and a receiving portion 10a is fixed to the end of the main body. The receiving portion 10a is a state in which two plate members 10a-1 and 10a-2 are raised from the main body 10M, and a V-shaped notch is formed at the center of the upper end thereof (see FIG. 4). By making the receiving part 10a into such a shape, the hook part FK of the hanger H can be stably held at a fixed position (V-shaped part).

  As shown in FIGS. 3 and 4, a first side plate 26 and a second side plate 27 are fixed to the side portion of the conveyor support member 24. The main body 10M is provided with a first bearing 11 at a position corresponding to the first side plate 26 and a second bearing 12 at a position corresponding to the second side plate 27. The first bearing 11 is in contact with the back side of the first side plate 26 (right side in FIG. 3), and the second bearing 12 is in contact with the front side of the second side plate 27 (left side in FIG. 3). The position is set. Therefore, when the carrier 10 is set from above the conveyor support member 24, the carrier 10 can be positioned by the first bearing 11 and the second bearing 12.

  After the carrier 10 is set on the conveyor support member 24, the first side plate 26 and the second side plate 27 of the conveyor support member 24 function as guide rails for the carrier 10. As described above, the rearrangement device 1 realizes a structure in which the carrier 10 is detachable from the transport device 2 and the carrier 10 moves along the transport device 2. As shown in FIG. 4, the carrier 10 is provided with two second bearings 12 before and after the conveying direction. When a plurality of bearings 12 are arranged in this manner, the running stability of the carrier 10 is improved. The same applies to the first bearing 11 although it is not visible in FIG.

  Further, as shown in FIG. 3, the conveyor 25 is disposed in a space formed between the upper surface of the conveyor support member 24 and the lower surface of the carrier 10. The conveyor 25 includes a chain 28 and a resin cover 29 having a U-shaped cross section formed so as to surround the outer periphery of the chain 28. The resin cover 29 is fixed to each block constituting the chain 28 as can be confirmed with reference to FIG. The resin cover 29 moves while its lower surface 29 </ b> B is in contact with the upper surface of the conveyor support member 24. Therefore, the conveyor 25 can move while maintaining the height position stably.

  The carrier 10 is arranged so that the lower surface 10B (second surface) is in contact with the upper surface (first surface) 29T of the resin cover 29. Therefore, the carrier 10 receives the conveying force via the lower surface 10B when the resin cover 29 moves, and therefore moves with the resin cover 29. The conveying force transmitted to the carrier 10 is transmitted based on a frictional force generated between the upper surface 29T of the resin cover 29 and the lower surface 10B of the carrier 10.

  Therefore, when the carrier 10 is pressed with a force stronger than the frictional force, a slip occurs (slides) between the carrier 10 and the resin cover 29, and the carrier 10 stops but the resin cover 29 moves. Can be formed. If a carrier stop mechanism for stopping the carrier 10 at a desired position is provided, it is convenient when performing an operation of rearranging clothes. Therefore, the rearrangement device 1 includes a carrier stop mechanism for holding the carrier 10 at a desired position. This carrier stopping mechanism will be described with reference to FIG.

  As shown in FIG. 3, the carrier 10 has a third bearing 13 serving as a contact portion on the rear side (right side in FIG. 3). A stopper device 30 is formed by the stopper 31 that comes into contact with the third bearing 13 and the actuator 32 that drives the stopper 31. Such a stopper device 30 can be disposed at a desired position in the conveyance path of FIG. The actuator 32 is driven to move the stopper 31 between the contact position where the stopper 31 contacts the third bearing 13 and the retracted position retracted from this position. When the stopper 31 is moved to the contact position, the carrier 10 can be stopped at that position. The actuator 32 may be controlled by the control device 8 (see FIG. 1).

  6 and 7 are views showing the transfer device 6 for changing the position of the carrier 10 shown in FIG. 6 is a diagram showing a configuration when the transfer device 6 and its peripheral devices are viewed in the transport direction (leftward in FIG. 1), and FIG. 7 is a front view of the transfer device 6 (upward in FIG. 1). It is a figure which shows a structure when it sees. The transfer device 6 shown in FIG. 1 has two sets of hand mechanisms 60 for transferring the carrier 10. Since these structures are the same, FIGS. 6 and 7 show the hand mechanism 60 on one side. As shown in FIG. 1, the hand mechanism 60 is fixed to a slider 9 that moves along the transport direction. The moving position of the slider 9 is controlled by the control device 8. Since the hand mechanism 60 shown in FIG. 1 is schematically shown, the holding hand faces in the horizontal direction, but the holding hand 61 shown in FIGS. 6 and 7 faces downward.

  6 and 7, the hand mechanism 60 is moved to a position approaching the carrier 10 and a position retracted by an actuator (not shown) disposed inside the slider 9. FIG. 6 shows a state where the hand mechanism 60 is close to the carrier 10. The hand mechanism 60 includes an actuator 63 that drives the holding hand 61. As shown in FIG. 7, the clamping hand 61 is formed as a pair of left and right. The sandwiching hand 61 is moved up and down by an actuator 63 and performs an operation of narrowing the width. The clamping hand 61 descends from the position shown in FIG. 6 and starts a clamping operation at a position where it comes into contact with the hanger H.

  The carrier 10 has a fourth bearing 14 that serves as an engaging portion. A ring member 14a is fixed to the front end side of the fourth bearing 14, and a portion of the fourth bearing 14 is a recess between the carrier body 10M and the ring member 14a. Further, on the hand mechanism 60 side, a pickup portion 64 that engages with the fourth bearing 14 serving as the concave portion is formed. The pickup portion 64 is formed so as to be lowered together with the sandwiching hand 61 so as to slide under the fourth bearing 14. Therefore, when the operation of clamping the hanger H by the clamping hand 61 is completed and the actuator 63 is raised, the pickup unit 64 is positioned below the fourth bearing 14. Therefore, if the hanger H is clamped and the clamping hand 61 is raised, the carrier 10 can also be lifted upward.

  By the way, when the transfer device 6 is driven as described above and the carrier 10 is removed from the conveyor support member 24 of the transport device 2, the operation is easy to perform if the carrier 10 is in a stopped state. Therefore, in the replacement device 1, the above-described stopper device 30 is disposed at a predetermined position of the transport device 2 to form a row in which the carriers 10 are stopped (FIG. 1). And the control apparatus 8 controls the transfer apparatus 6 based on the input of the instruction | indication input apparatus 5, removes the object carrier 10 from the conveyor support member 24, and moves (transfers) to another position. A series of operations for rearranging the carriers 10 will be described later.

  By the way, when one of the carriers 10 in the row as described above is removed by the rearrangement device 1, the carrier 10 upstream from the removed carrier 10 moves so as to fill the space. The space of the carrier 10 thus removed can be eliminated because each carrier 10 receives the conveying force from the conveyor 25 on the lower surface 10B as described above. In the conventional rearrangement device and transport device, the space from which clothes (conveyed objects) are removed remains as it is. However, since the rearrangement device 1 uses a detachable carrier, useless space is removed from the transport device 2. In the rearrangement device 1, since a useless space is immediately filled, continuous processing while continuously receiving clothes being conveyed is possible.

  Furthermore, the rearrangement device 1 includes a carrier push-back mechanism 70 attached to the hand mechanism 60 to push the carrier 10 back to the upstream side as a preferred configuration. The carrier push-back mechanism 70 is an auxiliary mechanism for reliably picking up the carrier 10 and the hanger H that are to be removed by the hand mechanism 60 described above. In FIG. 7, the carrier push-back mechanism 70 is illustrated. The carrier push-back mechanism 70 is fixed to the slider 9 adjacent to the hand mechanism 60. The carrier pushback mechanism 70 includes an actuator 71 and a pushback hand 72 moved by the actuator 71. The actuator 71 lowers the push-back hand 72 as indicated by the arrow Y and moves it upstream. When the push-back hand 72 operates in this way, the distance between the carrier 10 adjacent to the upstream side of the target carrier 10X can be increased. Therefore, the target carrier 10X and the hanger H can be reliably picked up by the hand mechanism 60. Although not shown in FIG. 7, a carrier push-back mechanism that increases the distance from the carrier 10 adjacent to the downstream side of the target carrier 10 </ b> X may be similarly provided.

  Furthermore, an outline of the operation when the control device 8 of the rearrangement device 1 receives an instruction of the clothing W to be rearranged from the instruction input device 5 will be described. FIG. 8 shows a state where the designated carrier 10 </ b> X is removed from the transport device 2 in order to rearrange the clothes W. In particular, after the carrier 10X is removed, the carrier 10Y is subsequently piped up. As is clear from the above description, each carrier 10 receives a conveying force from the conveyor 25 of the conveying device 2 in the conveying direction CW, so that the space of the previously removed carrier 10X is packed by the upstream carrier 10. .

  Therefore, for example, when the stopper device 30 described above is arranged at the reference position SP and the leading carrier 10A is stopped, the width of one of the carriers 10 is the same (for example, 70 mm). The position of the next carrier 10Y multiplied by W can be specified by the distance from the reference position SP. At this time, before the control device 8 controls the transfer device 6 to execute the removal operation, the information regarding the tag TG from the tag information reading device 4 and the latest arrangement changed by the carrier 10 removed by itself. With reference to the information, it is confirmed which distance the carrier 10Y to be removed next is from the reference position SP. Thereafter, the control device 8 controls the transfer device 6 to perform the removal operation of the carrier 10Y.

  As described above, the control device 8 can specify the target carrier 10 on the premise that the carriers are in close contact with each other. As described above, since each carrier 10 receives a conveyance force from the conveyor 25, adjacent carriers 10 come into contact with each other. However, if the carrier 10 does not move normally for some reason, the position of the removed symmetrical carrier 10 is shifted from the reference position SP. Therefore, the rearrangement device 1 includes an adhesion confirmation mechanism 80 for confirming that the carriers 10 are in close contact with each other.

  FIG. 8 shows an adhesion confirmation mechanism 80. The adhesion confirmation mechanism 80 includes a first energization device 81 installed at the reference position SP and a second energization device 84 (see FIG. 6) attached to the hand mechanism 60 of the transfer device 6. The first energization device 81 has an electrode 82, and the second energization device 84 has an electrode 85. These electrodes 82 and 85 are disposed so as to contact the contact 18 of the carrier 10, and the vertical movement control and conduction control are performed by the control device 8. The carrier 10 is formed of a conductive member such as an aluminum alloy.

  The control device 8 specifies the carrier 10 on which the corresponding hanger H is hung as described above when receiving an instruction to remove the predetermined clothing W by the instruction input device 5, and The electrode 82 and the electrode 85 of the second energization device 84 are brought into contact with the contact 18 of the carrier 10 to confirm whether there is electrical continuity. When the continuity is confirmed, the carriers 10 are normally arranged. Therefore, the control device 8 controls the removal of the carrier 10 by the above-described operation. When conduction cannot be confirmed, it is assumed that there is a gap in the row of carriers 10. In this case, it may be set so that the control device 8 stops the rearrangement process and issues a predetermined warning.

  A series of operations accompanying the rearrangement of the carriers 10 executed by the rearrangement apparatus 1 having the above-described configuration will be described with reference to FIG. The hangers H on which the clothes W are suspended after the management information of the tag TG is read are sequentially cut out by the cutting device 3 and are continuously supplied to the work set station of the transport device 2. A work set station, a carrier zone, a rearrangement zone, and a payout zone are set on the feed side of the transport apparatus 2 from the upstream side.

  The above-described stopper device 30 is disposed at the head of the carrier zone, and a plurality of carriers 10 are stopped while being adjacent to the upstream side of the stopper device 30. The head position of the carrier zone corresponds to the reference position SP described above. The control device 8 drives the transfer device 6 to remove the carrier 10 that has been instructed to be rearranged from the carrier zone from the transport device 2. The removed carrier 10 is again applied to the transport device 2 in the rearrangement zone downstream. In addition, if the stopper device 30 is also arranged at the head of the rearrangement zone, the related clothes W can be collected.

  After that, the carrier 10 moved to the rearrangement zone is picked up by the dispensing device 7 at the dispensing station. The emptied carrier 10 is returned to the work set station. In such a rearrangement operation, the carriers 10 on which the clothes W for which the rearrangement instruction has been placed are placed are sequentially removed from the carrier zone. Therefore, the next carrier can be accepted at the tail end of the carriers 10 arranged in the carrier zone. Therefore, the present rearrangement apparatus can perform continuous processing, and can perform rearrangement processing in a shorter time compared to the conventional case. In addition, since there is no useless space (a space left after the hanger is removed) in the transport device 2 as in the prior art, there is an advantage that the entire device can be made compact.

  As shown in FIG. 1, when the transfer device 6 includes two hand mechanisms 60, the two carriers 10 are removed from the carrier zone and moved to the rearrangement zone while the slider 9 is reciprocating once. Since it can be moved, processing efficiency can be improved. Of course, the transfer device 6 may include three or more hand mechanisms 60.

  As described above, the clothing rearrangement apparatus 1 rearranges clothing in a continuous process, but can be switched to batch processing as necessary. In order to perform batch processing, it is only necessary to arrange the stopper device 30 at a desired position in the carrier zone so as to separate the front and rear carriers. In the embodiment described above, clothing is used as an example of the object to be conveyed, but the present invention can be applied to all objects to be conveyed that are hung on the hanger H and rearranged.

  The preferred embodiment of the present invention has been described in detail above. However, the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims. Deformation / change is possible.
