Description

  The present invention relates to a laundry processing system suitable for use in commercial laundry facilities for rectangular linen laundry such as sheets, wrapping, and towels.

  As is well known, as a commercial laundry facility for cleaning a large number of laundry, a continuous water washing machine for washing laundry, a high-pressure dehydrator for dehydrating this washed laundry, A feeder that spreads the laundry that has been lumped by dehydration in a high-pressure dehydrator, a roll irona that dries the laundry stretched by the feeder and stretches the wrinkles of the laundry to adjust the shape, and supplied from this roll irona A thing provided with the folder which folds laundry is known. Some of such commercial laundry facilities include a pre-feeder that quickly sets a lump of laundry in a feeder and temporarily spreads the laundry in order to reduce labor.

For example, the pre-feeder 101 shown in FIG. 8 transports the laundry W from the loading position T of the laundry W to the delivery position D in the vicinity of the feeder 120, and two transport lines 102A for temporarily spreading the laundry W being transported. , 102B. These transfer lines 102 (102A, 102B) are arranged such that the transfer rails 103, 104 are arranged from above the input position T to above the delivery position D, and the end portions of these transfer rails 103, 104 are connected to the input position T. And the conveyors 105 and 106 which are respectively connected at the delivery position D, and a plurality of gripping tools 107 which can slide the transport rails 103 and 104 and grip one end of the laundry W.
The conveyance rail 103 is inclined downward from the loading position T side to the delivery position D side, while the conveyance rail 104 is inclined in the opposite direction to the conveyance rail 103. The elevating conveyor 105 (106) is configured to convey the gripping tool 107 supplied from the conveying rail 104 from the upper side to the lower side and then raise it again and supply it to the conveying rail 103. That is, the gripping tool 107 circulates in front of each worker at the loading position T and the delivery position D, and the worker at the loading position T causes the gripping tool 107 to grip one end of the laundry W, An operator at the delivery position D releases the laundry W of the gripper 107 and sets the laundry W in the feeder 120.
At this time, while the gripping tool 107 is raised by the lifting conveyor 105 and the transport rail 103 is slid by its own weight, the laundry W gripped by the gripping tool 107 is developed downward by the weight of the laundry W. In this state, the laundry W is easily set on the feeder 120, and the productivity is improved by providing a plurality of transfer lines.
As such a pre-feeder, there is one disclosed in Patent Document 1 below.
JP-A-4-259498

By the way, in order to reduce the work effort of the pre-feeder 101, a configuration in which the laundry W that has been temporarily spread is automatically supplied to the feeder 120 can be considered. However, when the laundry varieties are different, for example, when the size and material of the laundry are different, the roll speed of the roll iron following the feeder and the folding method in the folder are also different. Therefore, when the roll ironer and the folder processing (hereinafter referred to as “finishing processing”) are continuously performed on different types of laundry, the finishing processing of the previous-type laundry is finished and the subsequent-type laundry is performed. It is necessary to start the finishing process for the subsequent product after changing the setting of the finishing process according to the product. In other words, if the introduction of the rear product is started before the introduction of the previous product is completed, the laundry of the rear product will be finished in the setting of the laundry of the previous product, and the desired quality may not be obtained. The laundry may be damaged.
In addition, even if the settings of finishing processing are the same, if the laundry is grouped, for example, the laundry belongs to different customers, the laundry is mixed between different groups. End up.
In order to avoid these adverse effects, in a pre-feeder having a plurality of transfer lines, even if the introduction of the previous product is completed on one of the plurality of transfer lines, the previous product has not been input on the other transfer line. In the case of completion, it is necessary to wait for the introduction of the subsequent product until the input of the previous product in the other transport line is completed, and there is a problem that workability is deteriorated.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a laundry processing system having high efficiency workability without mixing different types of laundry. .

In order to achieve the above object, the present invention employs the following means.
That is, in the present invention, a plurality of transport lines that transport and store a predetermined number of laundry items that have been thrown in, a merging device that joins the laundry items that have been sent out from the plurality of transport lines, and a merging device And a subsequent processing device that performs provisional processing or main processing on the laundry, and a product change signal indicating that different types of laundry are input from any one of the plurality of transport lines. Until the product change signal is input from the other one of the transport lines, the delivery of the laundry of the rear product from one of the transport lines to the confluence portion of the confluence device is performed before the confluence portion. And a control unit that stops at the point.

According to the present invention, when the type change signal is input from any one of the plurality of transfer lines, the transfer from one of the transfer lines is continued until the type change signal is also input from the other transfer line. Since the delivery of the laundry of the kind to the joining part of the joining device is stopped before the joining part, the laundry of the previous kind is sequentially sent to the subsequent processing device and the processing is continued, while the washing of the succeeding kind of laundry is continued. Objects are stored in the transfer line without being sent to subsequent processing equipment. Thereby, mixing with a front breed and a back breed is prevented. Further, even if the loading of the previous-type laundry is not completed in all the conveyance lines, it is not necessary to wait for the loading of the subsequent-type laundry on the conveyance line in which the previous-type washing is completed. Thereby, highly efficient workability can be obtained.
Therefore, it is possible to provide a laundry processing system having high efficiency workability without mixing different types of laundry.

In addition, the control unit may change from one of the transfer lines to the merge unit of the laundry of the rear product on the condition that the setting change according to the laundry of the subsequent product of the subsequent processing device is completed. This is characterized in that the delivery of the is started.
Thus, after the setting change according to the laundry of the subsequent product of the subsequent processing device is completed, the laundry of the subsequent product is sent to the subsequent processing device. This processing can be reliably performed with the corresponding setting.

In addition, the control unit starts sending out the laundry of the rear varieties from one of the transport lines to the merging unit on condition that there is no laundry from the merging unit to the subsequent processing apparatus. It is characterized by doing.
As a result, on the condition that there is no more laundry from the junction to the subsequent processing device, the laundry of the rear product is sent to the subsequent processing device, so that the waiting for the processing of the laundry of the rear product is minimized. You can resume in time.

In addition, a product changeover switch is provided at the laundry loading position of each of the transport lines and outputs the product change signal to the control unit.
As a result, since the product changeover switch for outputting the product change signal is provided at the laundry input position, it is possible to minimize the burden on the operator who inputs the laundry and to simplify the apparatus configuration. .

Moreover, the said conveyance line is equipped with several pairs of holding tools which can each hold | grip the edge part of the said laundry, It is characterized by the above-mentioned.
Accordingly, since the pair of gripping tools capable of gripping the end portions of the laundry is provided, for example, when the linen-shaped laundry is gripped, the laundry can be stably gripped.

In addition, the gripping tool includes a groove portion that is formed in the laundry transport direction and can clamp the laundry, and is provided at the laundry loading position, and the pair of gripping tools is formed in a U shape in the vertical direction. An elevating part capable of elevating is provided.
Accordingly, since the elevating part that can lift and lower the pair of gripping tools in a U shape in the vertical direction is provided, for example, when gripping linen-like laundry, a gripping method that unifies the posture of all the laundry is adopted. Thus, it is possible to eliminate unevenness in processing performed by a pre-processing machine that performs a temporary process on the combined laundry and a subsequent apparatus that performs the main process (hereinafter referred to as “subsequent apparatus”).

  According to the present invention, when the type change signal is input from any one of the plurality of transfer lines, the transfer from one of the transfer lines is continued until the type change signal is also input from the other transfer line. Since the delivery of the laundry of the kind to the joining part of the joining device is stopped before the joining part, the laundry of the previous kind is sequentially sent to the pre-processing machine and the succeeding device, and the processing is continued, while the rear kind The laundry is stored in the transport line without being sent to the pre-processing machine or the succeeding apparatus. As a result, mixing of the previous product and the rear product is prevented, but even if the laundry of the previous product is not completed in all the transport lines, There is no need to wait for the laundry to be put in, and highly efficient workability can be obtained.

Thereafter, a laundry switching signal is input from all the other product type changeover switches 51, and after the stoppers 8 of the other transport lines 2 (2A to 2C) are operated through the same process as described above, On condition that the finishing process of the sent out laundry W has been completed, the settings of the roll ironer 30 and the folder 40 are changed, and the delivery of the laundry W from the respective transport rails 5 to the junction device 10 is started.

  Next, operation | movement of the laundry processing system S which consists of said structure is demonstrated using figures. In the following description, first, the conveyance operation of the laundry W (gripping tool 4) will be described, and then the correspondence relationship between the operator's input operation and the operation of the control unit 50 will be described.

As shown in FIG. 4, a plurality of pairs of gripping tools 4 are waiting on the one end portion 6a side of each transport rail 6 of the transport lines 2A to 2C. Each elevating conveyor 7 lowers the pair of gripping tools 4 on the top side downward, and as shown in FIG. Stop each on the descending side.
In this state, as shown in FIG. 5, each worker on the transport lines 2 </ b> A to 2 </ b> C introduces one end and the other end of the laundry W into the groove 4 a of each gripping tool 4, and then the one end and the other end. And the laundry W is gripped by the pair of grippers 4.

  Each lifting conveyor 7 transports the pair of gripping tools 4 gripping the laundry W upward by the lifting conveyor 7 and then sends them to the transport rail 5. As shown in FIG. 2, the gripping tool 4 sent to the transport rail 5 slides toward the junction device 10 because the transport rail 5 is inclined. During this time, the laundry W is developed downward by its own weight and temporarily spread.

The pair of gripping tools 4 moved to the merging device 10 side is stored in each transport rail 5 when the preceding pair of gripping tools 4 is present (see FIGS. 2 and 3). On the other hand, when there is no preceding pair of gripping tools 4, they are sent out to the junction 11.
The merging unit 11 alternately receives a pair of gripping tools 4 sent out from the transport lines 2A and 2B by receiving rails 11a and 11c and a pair of gripping tools 4 sent out from the transport lines 2B and 2C by receiving rails 11b and 11d. . Then, the pair of gripping tools 4 received by the receiving rails 11a and 11b are alternately sent to the forward path rotor portion 12A, and the pair of gripping tools 4 received by the receiving rails 11c and 11d are alternately sent to the forward path rotor portion 12B.
The forward rotor section 12 (12A, 12B) changes the arrangement direction of the pair of gripping tools 4 about 90 degrees with the vertical axis as the center of rotation, and sends it to the forward rail section 13 (13A, 13B).

The pair of gripping tools 4 sent out to the outward path rail portion 13 (13A, 13B) slide toward the supply conveyor 14 (14A, 14B) side because the outward rail portion 13 (13A, 13B) is inclined. To do. Thereafter, the gripping tool 4 is sent to the supply conveyor 14 (14A, 14B).
The supply conveyor 14 (14A, 14B) conveys the received pair of gripping tools 4 downward, and delivers the laundry W gripped by the pair of gripping tools 4 to the feeder 20. Thereafter, the gripping tool 4 that has become empty is conveyed upward and sent out to the return rail portion 15 (15A, 15B). The laundry W received by the feeder 20 is subjected to a tension spreading process, and then sent to the roll ironer 30, dried, wrinkled, molded, and folded in the folder 40.

  On the other hand, the gripping tool 4 fed to the return rail portion 15 (15A, 15B) slides toward the return distribution portion 17 side because the return rail portion 15 (15A, 15B) is provided with an inclination. Then, it is sent out to the return rotor section 16 (16A, 16B). The fed gripping tool 4 is changed in the arrangement direction of the front and rear gripping tools 4 by the return path rotor section 16 (16A, 16B) and distributed to the transport rail 6 via the return distribution section 17. The gripping tools 4 distributed to the respective transport rails 6 are slid by the inclination of the transport rail 6 and moved to the vicinity of the one end portion 6a, and again enter a standby state as shown in FIG.

  Next, the correspondence between the worker's input work and the operation of the control unit 50 will be described with reference to FIG. In the following description, the laundry W of different varieties is processed in succession, and the laundry W to be input first is referred to as the previous varieties of laundry W1, and the laundry W to be input next is referred to as the subsequent varieties of laundry W2. To do.

First, each worker starts throwing in the previous-type laundry W1 in each of the transport lines 2A to 2C (step S11).
The control unit 50 counts the number of laundry items loaded into the laundry lines 2A to 2C based on the detection signals input from the loading sensors (not shown) of the respective conveyance lines 2A to 2C ( Step S21). For example, when the input of the previous-type laundry W1 is started in the transport line 2A, the number of laundry input in the transport line 2A is counted.

  Next, the control part 50 is based on the detection signal input from the delivery sensor (not shown) of each conveyance line 2A-2C, and the quantity of the laundry W sent out from the conveyance rail 5 of each conveyance line 2A-2C. Is counted (step S22). For example, when the previous-type laundry W1 is sent out from the transport line 2A, the number of laundry delivered on the transport line 2A is counted.

  Next, the control part 50 calculates the laundry storage number stored in each conveyance line from the difference between the laundry input number and the laundry delivery number (step S23). For example, the number of stored laundry in the transport line 2A is calculated from the difference between the number of laundry thrown in the transport line 2A and the number of laundry delivered.

When the worker completes the introduction of the previous-type laundry W1, the worker presses the product changeover switch 51 corresponding to the transport line 2 (step S13). For example, when the input of the previous product laundry W1 is completed in the transport line 2A, the product type changeover switch 51 of the transport line 2A is pressed.
Based on the laundry switching signal input from the product changeover switch 51, the controller 50 stores the number of stored laundry when the laundry switching signal in the transport line 2 (2A to 2C) is input, and the transport line 2 thereof. The number of laundry delivered after the laundry switching signal in (2A to 2C) is input is collated (step S24). For example, the number of stored laundry when the laundry switching signal of the transport line 2A is input is compared with the number of laundry delivered after the laundry switching signal of the transport line 2 is input.

  After the operator presses the product type changeover switch 51, the worker continuously inputs the rear product type laundry W2 into the transport line 2 (2A to 2C) (step S14). For example, when the input of the previous product laundry W1 is completed in the transport line 2A, the input of the subsequent product laundry W2 to the transport line 2A even if the input of the previous product is not completed in the other transport lines 2B and 2C. To start.

  On the other hand, the control unit 50 determines whether or not the input quantity and the supply quantity of the laundry W when the laundry switching signal is input match (step S25). That is, it is determined whether or not the previous-type laundry W1 has been sent to the joining device 10 and the rear-variety laundry W2 is at the top.

  If the determination in step S25 is “Yes”, the stopper 8 is actuated to limit the delivery of the rear product laundry W2 to the joining device 10 (step S26). On the other hand, if the determination in step S25 is “No”, the process returns to step S24 again and collation is performed again.

  After operating the stopper 8, the control unit 50 determines whether or not the rear product laundry W2 is the head in the other transport line 2 (step S27). For example, when the stopper 8 of the transport line 2A is operated, it is determined whether or not the rear product laundry W2 is the head in the other transport lines 2B and 2C.

If the determination in step S27 is “No”, this determination is repeated until the rear product laundry W2 comes to the top in the other transport line 2.
If the determination in step S27 is “Yes”, the setting of the roll iron 30 and the folder 40 is changed to the subsequent product laundry W2 on the condition that the finishing processing of the roll iron 30 and the folder 40 of all the previous product laundry W1 has been completed. (Step S28).

  After changing the settings of the roll ironer 30 and the folder 40, the control unit 50 releases all the stoppers 8 and resumes the delivery of the subsequent-variety laundry W2 (step S29). Thereafter, the above-described operation is repeated.

  As described above, according to the laundry processing system S, when a product change signal is input from any one of the plurality of transport lines 2 (2A to 2C) (for example, the transport line 2A), the transport is performed. Until one of the line 2 (2A to 2C) (for example, the transport lines 2B and 2C) receives a product change signal, the rear product laundry W2 from one of the transport lines 2 (for example, the transport line 2A). Since the delivery to the junction unit 11 is stopped before the junction unit 11, the previous-type laundry W1 is sequentially sent to the feeder 20, the roll iron 30 and the folder 40, and the processing is continued, while the rear-type laundry W2 is stored in the transport line 2 (for example, the transport line 2A) without being sent to the feeder 20, the roll ironer 30, and the folder 40. As a result, mixing of the previous product laundry W1 and the rear product laundry W2 is prevented, while the input of the previous product laundry W1 has not been completed in all the transport lines 2 (for example, the transport lines 2B and 2C). However, it is not necessary to wait for the introduction of the rear product laundry W2 in the transport line 2 (for example, the transport line 2A) that has completed the input of the previous product laundry W1, so that highly efficient workability can be obtained.

  In addition, after the setting change according to the rear product laundry W2 of the roll irona 30 and the folder 40 is completed, the rear product laundry W2 is sent to the feeder 20, the roll ironer 30 and the folder 40. Thus, the processing can be reliably performed with the setting according to the subsequent product type.

Further, since the product changeover switch 51 for outputting the product change signal is provided at the input position T of the laundry W, the burden on the operator who inputs the laundry W is minimized, and the apparatus configuration is simplified. be able to.
In addition, since the pair of grippers 4 that can grip the end portions of the laundry W are provided, the laundry W can be stably gripped when the laundry W is gripped.

Moreover, since the elevating conveyor 7 that can lift and lower the pair of gripping tools 4 in a U-shape in the vertical direction is provided, it is possible to adopt a gripping method that unifies the postures of all the laundry W when gripping the laundry W. Accordingly, it is possible to eliminate unevenness in the stretching process by the feeder 20 and the finishing process by the roll ironer 30 and the folder 40.
For example, in the above description, the procedure for causing the gripping tool 4 to grip the rear-type laundry W is not particularly mentioned, but the laundry W is formed in a rectangular shape, and has four sides. In the case of a sheet having ears folded at two opposite ends, it is possible to unify the gripping posture of the laundry W by performing the following procedure. That is, after the worker finds one of the ears of the laundry W that has become a lump, the end of the ear is identified by tracing the ear, and as shown in FIG. After gripping the gripping tool 4 stopped on the ascending side so that one end is on the upper side, follow the ear gripped again so that the other end of the ear (one end side) is on the other end. Then, the gripper 4 stopped on the descending side is gripped. By doing so, the posture of the laundry W is prevented from being twisted or twisted, and the generation of the poorly finished laundry W can be effectively prevented. In addition, since such a procedure should just identify one end edge, even if it makes the holding tool 4 hold | grip the one end edge in which the ear | edge is not formed, the same effect can be acquired.

Note that the operation procedure shown in the above-described embodiment, various shapes and combinations of the constituent members, and the like are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.
For example, in the laundry processing system S described above, after the settings of the roll iron 30 and the folder 40 are changed, the delivery of the rear-type laundry W2 is resumed. On the condition that there is no more, the delivery of the rear product laundry W2 from one of the transport lines 2A to 2C to the joining portion 11 may be started.
With such a configuration, it is possible to resume the processing of the rear product laundry W2 with a minimum waiting time.

In the laundry processing system S described above, the control unit 50 changes the setting of the roll ironer 30 and the folder 40. However, the setting is changed manually, and a signal for changing the setting is transmitted to the control unit 50. It is good also as a structure.
In the laundry processing system S described above, a loading sensor (not shown) and a delivery sensor (not shown) are provided so that the controller 50 can recognize the quantity of stored laundry W. A switch to be pressed may be provided to supply the detection signal to the control unit 50, or the quantity of the laundry W may be recognized by image recognition. In addition, an individual identification number is assigned to each gripping tool 4 so that the control unit 50 can recognize this identification number, and grips the rear-type laundry W2 that has become the head in each transport line 2 (2A to 2C). It is good also as a structure which detects the holding | gripping tool 4 and stops sending out.

Moreover, in the laundry processing system S mentioned above, although the confluence | merging part 11 of the pre-feeder 1 was comprised movable, you may apply to the thing of a system like FIG. That is, the common bus type pre-feeder 61 includes a junction rail 62 that connects the conveyance rails 5 of the respective conveyance lines 2A to 2C, and the gripper 4 is attached to one end portion 62a (merging portion) side of the junction rail 62. A return distribution rail 63 connected to the conveyance rail 6 is provided at the upper side, and the end of the return distribution rail 63 is provided. In 63a, the gripper 4 is returned to the transport rail 6. In addition, the same code | symbol is attached | subjected to the component similar to FIGS.
Moreover, in the laundry processing system S mentioned above, although comprised from the three conveyance lines 2, this invention can be applied from two things.
