Description

In the present invention, in order to spread the cloth washed in a cloth washing factory or the like one by one and send it to the next step, the adjacent corners of the cloth are gripped by a pair of stretching clamps, and the corners of the cloth are held. It is used in a cloth stretching device that stretches the upper side between the parts in the left-right direction and carries out the cloth that stretches the upper side to the rear. It relates to a cloth supply device that delivers the matching corners to the pair of extension clamps.

As a conventional cloth stretching device, for example, the one described in Patent Document 1 previously disclosed by the applicant of the present application is known, and this cloth stretching device includes a cloth loading section and a loaded cloth. It is equipped with an extension section that stretches the cloth to the left and right, and a carry-out section that carries out the stretched cloth.

However, in the conventional cloth stretching device described in Patent Document 1, the traversing device moves a pair of stretching clamps together to each delivery position of a plurality of loading portions, and the cloth is adjacent to the stretching clamps. After gripping the corners, the pair of extension clamps are traversed in the direction away from each other to spread the cloth in the left-right direction, so the operation time from loading to extension is shortened and the processing efficiency is sufficiently improved. It was still difficult.

In addition, when spreading multiple types of cloth, especially cloths with different upper side widths, if they are mixed, a pair of input clamps will be used when spreading cloths with a large upper side width. The moving distance of the pair of extension clamps from the delivery position at a predetermined interval becomes large, and it takes time to extend. In this respect as well, it is still difficult to sufficiently improve the processing efficiency.

Therefore, in order to solve the above-mentioned problems of the conventional cloth stretching device, it is conceivable to supply the cloth from the cloth supplying device to the cloth stretching device. The ones listed are known. This cloth loading device transfers the pair of clamps holding the adjacent corners of the upper side of the cloth at predetermined intervals, and the height of the lower end of the hanging upper side of the cloth and the maximum of the cloth. The height of the lower end is detected by a sensor, and the cloth is sorted and stored by type based on the width and length of the cloth obtained from those heights, and the cloth is put into the processing device for each type.

Further, as a conventional cloth supply device, for example, the one described in Patent Document 3 is also known, and this cloth loading device has adjacent corners of cloth at each loading position of a plurality of loading portions. After storing multiple pairs of loading clamps that grip the parts in multiple transport paths, they are merged into a common transport path and transported, and then paired and separated near the cloth spreading device to a common delivery position. In addition to sending, merging and waiting for a common transport path are performed according to the type of cloth, avoiding the mixing process of multiple types of cloth.

However, even if the conventional cloth supply device sorts the cloth by type and hands the corners of the cloth to the pair of stretch clamps of the cloth stretcher, it is common to stretch the cloth. It was estimated that the moving distance of the extension clamp from the delivery position is still large for cloth with a large upper side width, and it is difficult to sufficiently improve the processing efficiency.

An object of the present invention is to provide a cloth supply device that advantageously solves the problems of the conventional cloth stretching device as described above, and the cloth supply device of the present invention is used.
A pair of stretch clamps grips adjacent corners of the cloth, stretches the upper side between the corners of the cloth in the left-right direction, and carries out the cloth with the stretched upper side to the rear. In a cloth supply device used for a stretching device, the loaded cloths are conveyed one by one and the adjacent corners of the cloths are delivered to the pair of stretching clamps.
A pair of transport clamps that insert and grip adjacent corners of the upper side of the cloth side by side, and two measurement paths that extend in parallel at predetermined intervals.
A slack sensor that measures the degree of slack in the upper side between the corners of the cloth gripped by the pair of transport clamps that pass through the two measurement paths side by side.
A plurality of slack-specific supply paths, which are branched from the two measurement paths and are determined according to the degree of slack in the upper side portion.
A pair of transport clamps gripping the corners of the cloth are passed through two slack supply paths corresponding to the degree of slack in the upper side of the cloth among the slack supply paths of the plurality of paths. , The pair of extension clamps positioned corresponding to the two slack supply paths through the pair of transfer clamps among the plurality of slack supply paths, and the cloth from the pair of transfer clamps. Cloth classification supply control means to hand over the corners,
It is characterized by having.

In the cloth supply device of the present invention, a pair of transport clamps that insert and grip adjacent corners of the upper side of the cloth side by side two measurement paths extending in parallel at predetermined intervals. The slack sensor measures the degree of slack in the upper side between the corners of the cloth gripped by a pair of transport clamps that pass through the measurement paths of the two paths side by side. The pair of transport clamps that grip the corners of the type are branched from the measurement paths of the two paths, and the cloth of the cloth is out of the multiple paths of the supply path for each slack, which are determined according to the degree of slack in the upper side. By passing through each of the two slack supply paths corresponding to the degree of slack in the upper side, it is positioned corresponding to the two slack supply paths through the pair of transport clamps among the multiple slack supply paths. The corners of the cloth are delivered from the pair of transport clamps to the pair of extension clamps.

Therefore, according to the cloth supply device of the present invention, the degree of slack in the upper side between the corners of the cloth gripped by a pair of transport clamps that pass side by side through two measurement paths extending in parallel at predetermined intervals. Based on the result measured by the slack sensor, for the type of cloth whose upper side width is estimated from the degree of slack, the cloth among the multiple slack supply routes determined according to the degree of slack. Since those corners are handed over to the extension clamps placed at the corresponding positions through the two slack-separated supply paths corresponding to the degree of slack in the upper side, the movement distance of the extension clamp when extending the cloth can be determined. The width of the upper side of the cloth can be made smaller regardless of the type of cloth, the spreading time can be shortened, and the processing efficiency can be sufficiently improved.

In the cloth supply device of the present invention, the measurement paths of the two paths may be branched downward to serve as the slack-separated supply paths of the plurality of paths.

In this way, almost no factory floor area is required for branching from the measurement path to the slack-separated supply path of multiple paths, so that the efficiency of the cloth supply space can be improved and the equipment cost can be reduced. can.

Here, the slack-separated supply path to which the measurement paths of the two paths branch from each other may be two paths, an outer supply path and an inner supply path.

It is sectional drawing seen from the part A in FIG. 1 of the cloth supply apparatus of the said embodiment. It is a top view which shows one configuration example of only the supply rail line among the rail lines of the cloth supply apparatus of the said embodiment. It is a top view which shows one configuration example of only the recovery rail line among the rail lines of the cloth supply apparatus of the said embodiment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Here, FIG. 1 is a side view showing an embodiment of the cloth supply device of the present invention together with a cross section of a cloth extension device using the same, and FIG. 2 is a side view of the cloth supply device of the above embodiment. FIG. 1 is a cross-sectional view seen from part A in FIG. 1, FIG. 3 is a plan view showing a configuration example of only the supply rail line among the rail lines of the cloth supply device of the above embodiment, and FIG. 4 is the above-mentioned embodiment. It is a top view which shows one configuration example of only the recovery rail line among the rail lines of the cloth supply apparatus of the form.

The cloth stretching device 1 using the cloth supplying device of this embodiment stretches the washed cloth one by one in order to put the washed cloth into, for example, an iron roller in the next step, for example, in a cloth washing factory. As illustrated in the cross section in FIG. 2, the front view in FIG. 2, and the plan view in FIGS. It is equipped with a supply device 10, an extension section 2 that extends the loaded cloth to the left and right, and a carry-out section 3 that carries out the stretched cloth. It is configured in the same way as in the cloth stretching device of.

That is, in the extension portion 2, the pair of extension clamps 2a that receive and grip the adjacent corners of the cloth C from the pair of transfer clamps at a predetermined delivery position and the pair of extension clamps 2a are traversed together. After the pair of extension clamps 2a grip the adjacent corners of the cloth C at the delivery position, the pair of extension clamps 2a are traversed in the direction away from each other to spread the cloth C in the left-right direction. And have. Then, the carry-out portion 3 receives the upper side portion of the cloth C spread in the left-right direction from the extension clamp 2a at the forward position, and has a catch base 3a as an intermediate moving body that sucks and holds the upper side portion on the upper surface in an extended state by negative pressure. As the catch base 3a moves backward and the negative pressure is removed, the upper side of the cloth C spread in the left-right direction is received, attracted and held by the negative pressure, and pulled backward, and more than the upper side of the cloth C. It also has a belt conveyor 3b that sequentially pulls up the remaining portion on the lower side and carries out the entire cloth C to the rear.

On the other hand, the cloth supply device 10 of the above-described embodiment has adjacent corners of the cloth C loaded into a pair of transport clamps 11 having a lever-shaped claw and a traveling roller, each of which is urged by a spring to close. A common transport path 12 for gripping and transporting each of these transport clamps 11 and a common transport path 12 branching left and right in front of the cloth spreading device 1 and extending in parallel with each other at a predetermined interval LM. The upper side between the corners of the cloth C gripped by the pair of transport clamps 11 that sequentially deviate from the common transport path 12 and pass through the measurement paths 13 of the two paths side by side. For example, the slack sensor 14 that optically measures the magnitude of the slack of the part by the amount of light received and outputs it as an ON-OFF signal, and the slack sensor 14 that is branched from the measurement paths 13 of these two paths, respectively, as a supply path for each slack. It is equipped with an inner supply route 15 of the route, an outer supply route 16 of two routes, and a controller 17 having a normal computer as a cloth classification supply control means, and a common transport route 12 and a measurement route 13 thereof. The inner supply path 15 and the outer supply path 16 are formed by, for example, rails having a substantially U-shaped cross section in which the central portion of the downward surface is cut out along the longitudinal direction to form the supply rail line 18, and the measurement path is formed. A normal switching mechanism 19 is provided at the branch point from the 13 to the inner supply path 15 and the outer supply path 16.

Here, the inner supply paths 15 of the two paths extend parallel to each other at a predetermined interval L1, and the outer supply paths 16 of the two paths extend parallel to each other at a predetermined interval L2 larger than L1, and the inner supply paths 15 and Each of the outer supply paths 16 has a substantially U-shape in which the lower ends of the descending path connected to the measurement path 13 and the ascending path facing the stretched portion 2 of the cloth stretching device 1 are connected by an arc-shaped connecting portion. In the descending path, the transport clamp 11 travels by gravity due to its own weight and the weight of the cloth C gripped therein, but from the connecting portion to the upper end portion of the ascending path, for example, as in the conventional loading portion. An endless timing belt arranged along the side of the path is driven by a servomotor, a step motor, or the like, and one of a large number of pins projecting along the extending direction of the timing belt is attached to the transport clamp 11. A drive mechanism (not shown) for driving the transfer clamp 11 by engaging with the transfer clamp 11 is provided to control the movement of the transfer clamp 11.

Then, when the controller 17 receives the ON (high light receiving amount) signal from the slack sensor 14, it determines that the cloth C has a larger degree of slack in the upper side portion, and grips the corner portion of the cloth C. The pair of transport clamps 11 are passed through the two-path measurement path 13 to the left and right two-path outer supply paths 16 by the switching mechanism 19, and when an OFF (light receiving amount) signal is received from the slack sensor 14, the upper side portion thereof. It is determined that the cloth C has a smaller degree of slack, and the pair of transport clamps 11 gripping the corners of the cloth C are switched from the measurement path 13 of the two paths to the inside of the two left and right paths by the switching mechanism 19. It remains in the inner supply path 15 and the outer supply path 16 due to the number of transport clamps 11 that have passed through the supply paths 15 and the switching mechanism 19 and the number of expansion operations of the extension clamp 2a of the cloth extension device 1. The number of the transfer clamps 11 is determined, and the transfer clamp 11 of the outer supply path 16 or the inner supply path 15 of each of the two left and right paths passed through the pair of transfer clamps 11 remains in the cloth stretching device 1. A pair of extension clamps 2a are arranged so as to face the ascending paths of the two left and right paths of the supply path, and the transfer clamp 11 is hooked by a normal hooking mechanism (not shown) on the descending path of the remaining supply path. From the pair of transport clamps 11 to the pair of extension clamps 2a that are driven by the drive mechanism and move up through the ascending path, the cloth C is sent to the ascending path by releasing the first pair of transport clamps 11. Hand over the adjacent corners of the upper side.

Therefore, according to the cloth supply device of the above embodiment, the pair of extension clamps 2a receive the corner portion of the cloth C at a position corresponding to the width of the upper side portion of the cloth C to be expanded next. The moving distance of the stretching clamp 2a when stretching C can be reduced regardless of the width of the upper side of the cloth C to shorten the stretching time and improve the processing efficiency.

The cloth supply device 10 of the above embodiment also has one or a plurality of charging sections 20 as corner independent feeding means having two feeding paths 21 parallel to each other at predetermined intervals, and four places in the illustrated example. As in the inner supply path 15 and the outer supply path 16, the two-path input path 21 in each loading section 20 has a descending path located far from the cloth stretching device 1 and close to the cloth stretching device 1, respectively. It has a substantially U-shape in which the lower ends of the ascending path located on the side are connected to each other by an arc-shaped connecting portion. To the upper end of the path, for example, as in the conventional input section, an endless timing belt arranged along the side of the path is driven by a servomotor, a step motor, etc., and the timing belt extends in the extending direction. A drive mechanism (not shown) for driving the transport clamp 11 by engaging any of a large number of pins projecting side by side with the transport clamp 11 is provided to control the movement of the transport clamp 11 and controls the movement of the transport clamp 11. The drive mechanisms of 21 operate independently of each other, and the controller 17 is a switch according to the width type of the upper side of the cloth supplied to the input portion 20 of the worker W, for example, by the supply conveyor S. By operation, these drive mechanisms are sequentially activated to raise the pair of transport clamps 11 at intervals from each other according to the size of the width of the upper side of the cloth to be loaded.

Therefore, according to the cloth supply device of the above embodiment, one corner of the pair of transport clamps 11 is provided at the lower end of the loading path 21 according to the width of the upper side of the cloth to be loaded. After gripping, the other corner of the cloth C, which is easy to find because one corner is pulled up by the ascending movement of the transport clamp 11, is gripped by the other transport clamp 11 at the lower end of the feeding path 21. Therefore, it is possible to increase the charging efficiency of the cloth C.

The two-path input paths 21 in each input section 20 merge with each other at the upper end of the ascending path and are connected to the one-path storage path 22 inclined forward and downward, and the one-path storage path 22 is viewed in plan. In the storage path 22, the transport clamp 11 travels and moves due to its own weight and the weight of the cloth C gripped there, but in the common transport path 12, it joins the common transport path 12 having a substantially U-shape. The endless timing belt 23 arranged along the lower part of the path is driven by a servomotor, a step motor, or the like, and any of a large number of pins 24 protruding in the extending direction of the timing belt 23 is conveyed. A drive mechanism 25 for driving the transfer clamp 11 by engaging with the clamp 11 is provided to control the movement of the transfer clamp 11, and the two-path feeding path 21 and the one-path storage path 22 in each of these loading sections 20 are controlled. The transport path 12 common to the above also constitutes the supply rail line 18.

Here, at the confluence point from the storage path 22 of one path of each input unit 20 to the common transfer path 12, one or a plurality of pairs of transfer clamps 11 are stored in the storage path 22 and among those transfer clamps 11. A normal hooking mechanism (not shown) is provided in which the first pair of transport clamps 11 are passed through the common transport path 12 in a front-to-back state, and the controller 17 is a switch of the operator W for each type of cloth C. The number of operations and the confluence point detected by a contact type such as a micro switch or a non-contact type non-contact type passage detector such as an optical sensor provided near the downstream side of each confluence point in the common transport path 12 are detected. Data of the number of the transfer clamps 11 that have passed and the number of the transfer clamps 11 that have passed through the hooking mechanism detected by the same passage detector are input.

Then, the controller 17 determines from those data the type of the cloth C stored in the storage path 22 and the order of the pair of the transport clamps 11 that grip the cloth C, and sets the common transport path 12 from the upstream side thereof. If the same type of cloth as the type of cloth C (for example, A) that has passed through and passed through the confluence is at the head of the storage path 22, a pair of heads that are hooked by the hooking mechanism at the confluence. With the type of cloth C (for example, the first type A) in which the transport clamp 11 is released, the storage path 22 is passed through the common transport path 12, the common transport path 12 is passed from the upstream side thereof, and the confluence point is passed. If a different type of cloth C (eg, second type B) is at the beginning of the storage path 22, wait a certain amount of time after the previous type (eg, first type A) has passed its confluence. After opening, the pair of transport clamps 11 at the head of the storage path 22 are released, or the cloth C of the same type as the cloth C at the head of the storage path 22 (for example, the second type B) is common. It passes through the transport path 12 from the upstream side, waits until it passes through the confluence, releases the pair of transport clamps 11 at the head thereof, and passes from the storage path 22 to the common transport path 12.

Therefore, according to the cloth supply device of the above embodiment, the first or second type of cloth C having the same width of the upper side portion of the first type A and the second type B is stretched. Since the extension clamp 2a of the device 1 can continuously extend the cloth C from the same delivery position, the moving distance of the extension clamp 2a when extending the cloth C can be further reduced to shorten the extension time and improve the processing efficiency. It is possible to carry out the cloth C by the type and carry it out from the cloth spreading device 1.

Further, in the cloth supply device of this embodiment, the measurement paths 13 of the two paths are branched downward, respectively, and the inner supply path 15 of the two paths and the outer supply path of the two paths as the slack-separated supply paths of the plurality of paths are branched. It is 16.

Therefore, according to the cloth supply device of the above embodiment, since the floor area of the factory for branching from the measurement path 13 to the inner supply path 15 and the outer supply path 16 is hardly required, the supply space of the cloth C is required. It is possible to increase the efficiency of the equipment and reduce the equipment cost.

Further, the cloth supply device of this embodiment is connected to the upper end of each ascending path of the inner supply path 15 of the two paths and the outer supply path 16 of the two paths, and the return path 26 of the four paths inclined forward and downward. A common return path 27 having a substantially U-shape in a plan view in which the return paths 26 of these four paths are sequentially merged, and a branch from the common return path 27 toward each input section 20, and further input. A transport clamp supply path 28 that is branched in two at the portion 20 and is connected to the upper end of the descending path of the input path 21 of the two paths and is inclined forward is provided. In the common return path 27, the endless timing belt 29 arranged along the upper part of the path is driven by a servomotor, a step motor, or the like, and the timing belt 29 is used to drive the timing belt 29. A drive mechanism 31 for driving the transfer clamp 11 by engaging any of a large number of pins 30 projecting side by side in the extending direction with the transfer clamp 11 is provided to control the movement of the transfer clamp 11.

The return path 27 common to the return path 26 of the four paths and the transfer clamp supply path 28 are each formed of, for example, a rail having a substantially U-shaped cross section in which the central portion of the upward surface is cut out along the longitudinal direction. The recovery rail line 32 is configured, and each branch point from the common return path 27 to the transfer clamp supply path 28 is provided in the vicinity of the upstream side of each branch point in the common return path 27 in the same manner as described above. A passage detector (not shown) is provided, and a normal switching mechanism (not shown) similar to the switching mechanism 19 is provided. The controller 17 switches the transport clamp 11 passing through the branch point detected by the passage detector. Separated one by one with, and sequentially passed through the transport clamp supply path 28 of the four loading portions 20.

Therefore, according to the cloth supply device of the above embodiment, the corner portion of the cloth C is handed over to the extension clamp 2a in each ascending path of the inner supply path 15 of the two paths and the outer supply path 16 of the two paths. The transport clamps 11 of the above are gathered in a common return path 27 through the return path 26 by descent due to their own weight, and then supplied in pairs to the transport clamp supply path 28 of each charging unit 20 from the transport clamp supply path 28. It is returned to the upper end of the descending path of the loading path 21 and waits for the worker W to be sent to the loading path 21 by activating the drive mechanism by operating a switch according to the type of the width of the upper side of the cloth to be loaded. Therefore, the cloth C can be put in efficiently.

Although described above based on the illustrated example, the present invention is not limited to the above example and can be appropriately modified within the scope of the claims. For example, in the cloth supply device of the above embodiment. Although the controller 17 is provided separately from the control device provided by the cloth extension device 1, the control device provided by the cloth extension device 1 may also be used as the controller 17, and the separate controller 17 may be omitted.

Further, in the cloth supply device of the above embodiment, the measurement path of the two paths is branched into the inner supply path 15 of the two paths and the outer supply path 16 of the two paths as separate supply paths by slack according to the slack of the upper side portion. However, each of the two measurement paths may be branched into a larger number of slack-separated supply paths.

Then, in the cloth supply device of the above embodiment, the first type and the second type of the cloth C are separated by the difference in the width of the upper side portion, but instead of this, the width of the upper side portion thereof. It may be divided according to the difference in the type of cloth such as sheets and covers that can be seen from the difference, the difference in the customer, etc. Even in this way, multiple pieces of cloth of the same type can be continuously used as a cloth spreading device. It can be supplied to sufficiently increase its processing efficiency.

Thus, according to the cloth supply device of the present invention, the degree of slack in the upper side between the corners of the cloth gripped by a pair of transport clamps that pass side by side through the two measurement paths extending in parallel at predetermined intervals. For a type of cloth whose upper side width is estimated from the degree of slack based on the results measured by the slack sensor, of the multiple routes of supply routes for each slack determined according to the degree of slack. Since those corners are handed over to the extension clamps placed at the corresponding positions by passing through each of the two slack supply paths corresponding to the degree of slack in the upper side, the movement distance of the extension clamp when extending the cloth is increased. The width of the upper side of the class can be reduced regardless of the type of cloth to shorten the spreading time and the processing efficiency can be sufficiently improved.
