Description

The invention relates to a handling device for flexible material blanks with the features in the independent claims.

It is known from practice to manually stack supplied flexible material blanks.

It is the object of the present invention to provide an improved and efficient handling technique.

The invention solves this problem with the features in the independent claims.

The claimed handling technique, i.e. the handling equipment and the handling method, has several advantages.

The handling technology makes it possible to stack material blanks fed in rows in a continuous stream of blanks at a stacking point and to form a temporary and height-adjustable stack of blanks there. The material blanks fed in rows are isolated and have an axial distance from one another in the feed direction. The handling technology is particularly efficient. It allows the finished stack of blanks to be discharged without interrupting the flow of blanks and the formation of the stack. While the finished stack of blanks is being removed, a new stack of blanks can be formed at the same stacking point without said interruption of the stream of blanks.

The lowering and removal of the finished stack of blanks can take a significantly longer period of time than the cyclical stacking of the individual material blanks on the new stack of blanks. The cycle time for stacking can be about 3 seconds or less, for example. The lowering and removal time can be a multiple of the cycle time, e.g. about 10 seconds. In this time period, for example, two or more layers of blanks can be formed on the new stack of blanks.

For this purpose, the handling device can comprise a feed device and a stacking device connected there with a corresponding design and function.

The stacking device can stack the supplied material blanks on a stack carrier. This can preferably be a loose stack carrier, e.g. a pallet. In another variant, a stack carrier can be attached to a component of the stacking device, in particular to a carrier feed. The finished stack of blanks can be discharged together with a loose stack carrier or alternatively without the said built-on stack carrier.

The claimed stacking technique is particularly efficient. It can intermittently form stacks of blanks from a continuous and uninterrupted stream of blanks and remove them intermittently. The stream of blanks can have a constant and optimized speed and does not need to be slowed down for the pile change. Stack formation can also proceed unimpeded.

The stack can be formed either on a loose stack carrier or in a self-supporting stack of blanks. In this way, different material properties of the flexible material blanks can be taken into account. A loose stacking support is advantageous for unstable material cuts.

The flexible material cuts are preferably cuts made from a nonwoven fleece. This can be formed from a textile fiber material, in particular short-cut staple fibers made from natural fibers and/or synthetic fibers. Such a nonwoven web can already be at least partially consolidated, e.g. by thermobonding, needling, hydroentanglement or the like.

The claimed handling technique also has the advantage that it can place such unstable material blanks on the stack individually, in a precise position and without undesired deformation of the blanks. Flexibly elastic and sensitive material cuts, in particular nonwoven fleece cuts, can be treated particularly gently and placed on the stack during stack formation.

In terms of device technology, the stacking device can comprise a number of components. This can include a depositing device, a carrier feed and a lifting device. The depositing device is designed to temporarily receive the supplied individual material blanks and place them on the stack of blanks. The individual material cut can be filed after it has been picked up. The carrier feed is designed to feed a stack carrier to the stacking point. This can be a loose stack carrier or the aforementioned built-on stack carrier. The lifting device is designed to accommodate the stack of blanks and any loose stack carrier temporarily and in a height-adjustable manner.

The carrier feed is designed in particular to temporarily accommodate a new stack of blanks at the stacking point, while a previously formed stack of blanks is being removed by the lowered lifting device. The lifting device can be designed to take over the new stack of blanks from the carrier feed after removal. If necessary, this can be done together with a loose stack carrier. For this purpose, the lifting device can be raised again from its lowered discharge position for carrier feeding.

There are various possibilities for the lifting device to take over the new stack of blanks temporarily formed at the carrier feed. The carrier feeder can, for example, grab a loose stack carrier from the side and then release it as soon as the loose stack carrier rests on the lifting device. In another variant, the lifting device and the guide can be designed in such a way that they can penetrate one another in the vertical direction. For this purpose, complementary support webs and receiving lanes can be present, which also allow the carrier feed to be withdrawn after the newly formed blank stack has been received by the lifting device. Other structural and functional variants are also possible.

The stacking device can include a relative height adjustment between the depositing device and the carrier feed. This is advantageous if the stack of blanks temporarily and newly formed at the carrier feed has an increasing height and comprises several layers of blanks. The depositing process can be adapted to the stack height and made more uniform by such a height adjustment. The height adjustment can be designed in different ways, both structurally and functionally. For example, the carrier feed can be lowered in relation to the depositing device. As an alternative or in addition, the depositing device can be raised at the stacking point in relation to the carrier feed.

The carrier feed can be designed to feed a loose stack carrier or an attached stack carrier below the depositing device at the stacking point. The carrier feed moves below the depositing device, whereby the depositing process can take place in the same way as on a stack of blanks carried by the lifting device. The lifting device can also be located at the stacking point below the depositing device. The carrier feed and the depositing device can be arranged at the stacking point on opposite sides and can move in opposite directions, preferably with a parallel, in particular horizontal, direction of movement.

The carrier feed can be designed to feed an attached or preferably loose stack carrier to the stacking point, while a material blank is picked up by the depositing device during this time. The carrier feed and the depositing device can perform the opposite movement mentioned at the stacking point. This allows for an overlap in time between the supply of stack carriers and the picking up of a material blank from the depositing device. At the same time, the previously formed, finished stack of blanks can also be lowered and removed by the lifting device. The time required for the stack removal is greater than the time required for picking up a single material blank from the depositing device.

On the other hand, the time required for the blank to be picked up by the depositing device is long enough to bring an attached or preferably loose stack carrier into position at the stacking point and then immediately deposit the material blank that has just been picked up by the depositing device onto the carrier feed and the positioned attached or loose stack carrier. The time required for depositing may be shorter than the time required for receiving the blank.

Buffering takes place during said recording, which enables the attached or loose stack carrier to be changed without interrupting the continuous flow of blanks and without interrupting the formation of the stack. The e.g. in the shortened and correspondingly accelerated depositing process can be adapted to the preferred constant feed speed of the blank stream and to the length of the axial distances between the separated material blanks in the blank stream. The depositing process can be ended before the next material blank which has been spaced apart arrives at a transfer point and is ready to be picked up by the depositing device.

The depositing device can advantageously be arranged below a transfer conveyor and a transfer point for the stream of blanks of material blanks. The depositing device can also move relative to the preferably stationary transfer conveyor, in particular in a horizontal, e.g. horizontal, direction.

There are various options for the constructive and functional design of the depositing device. In a preferred embodiment, the depositing device can be placed in a lying position include ordered circulating conveyor, which can be moved reversingly by means of an adjustment device over the stacking point and over the preferably loose stack carrier. The travel movement is preferably linear, but can alternatively have a different orientation.

The depositing device can be controlled in such a way that the circulating conveyor performs a preferably horizontal forward travel movement when picking up a single material blank. The direction and speed of this travel movement can be adapted to the feed movement of the material blank, e.g. adjusted. The forward travel movement can take place without a rotary or revolving movement of the circulating conveyor.

The depositing device can also be controlled in such a way that the circulating conveyor performs a preferably horizontal reverse movement with a superimposed circulating movement when depositing the individual material blank that has been picked up. The reverse movement can be accelerated compared to the forward movement. In this case, the picked-up material blank can be set down more quickly and in a shorter time than the previous pick-up of an individual material blank.

The return movement and the superimposed revolving movement can be adapted to the feed speed of the stream of blanks and to the length of the distances between the individual material blanks in the stream of blanks. The depositing process can thus take place in the same period of time that a spaced new material blank needs to arrive at a transfer point and to be able to be picked up by the depositing device, in particular by its circulating conveyor.

The carrier feed can be designed to feed a stack carrier to the stacking point and to keep it there temporarily and in a floating manner. This can be a built-on stack carrier or a preferably loose stack carrier, e.g. a pallet. In the case of a loose stack carrier, the carrier guide can also be designed to feed the loose stack carrier from a provision for such stack carriers to the stacking point.

The carrier feed can be designed in different ways to perform these functions. For example, it may comprise a support means with a transport device.

The support means may have an attached stack support. On the other hand, it can be designed to grip a loose stack carrier. The support means may also be configured to temporarily and floatingly hold the attached or loose stack support at the stacking location. For this purpose, the support means can have a cantilever-like shape, which is arranged and aligned lying, in particular horizontally.

Controllable gripping means can be arranged on the support means in the above-mentioned manner, which grip and hold a loose stack carrier laterally during the formation of a new stack of blanks and release it again after this stack of blanks has been taken over by the lifting device.

Alternatively, a support means can be designed in a different way. For example, it can preferably have straight support arms that correspond to corresponding receiving aisles on the lifting device and are aligned in the infeed direction of the carrier feed. The support arms can form an attached stack support at the top. The support arms can have a rigid surface. They may alternatively include a conveyor which pulls, for example, a loose stack carrier onto the support arm. This can be done, for example, at the provision for loose stack carriers. In a further embodiment, a support means can be designed as a horizontal, in particular horizontal, extendable support arm arrangement, onto which a loose stack carrier is pushed by means of a feed device from the preparation.

The transport device can be designed, for example, to move the support means reversingly towards the stacking point and away from the stacking point again, whereby the stacking point is cleared and the acceptance of a stack of blanks by the lifting device is not prevented. On the other hand, the transport device can be designed to bring about the aforementioned advancement of a loose stack carrier from the provision onto the support means positioned at the stacking point. The transport device can also be designed to move the support means reversingly between the stacking point and a provision for loose stack carriers. Furthermore, the transport device can also include a height adjustment for the support means, as mentioned at the outset.

The stacking device can have a removal device which is designed to remove a finished stack of blanks from the lowered lifting device. If necessary, the removal can take place together with a loose stack carrier. The discharge device can include a suitable stack conveyor for this purpose. This can be arranged separately and stationary or arranged on the lifting device. The finished stack of blanks can be stationary from the discharge device at a delivery point for collection by a transporter, for example a Forklifts to be provided. Alternatively, the stack of blanks can be transferred to another running conveyor device, eg a conveyor belt, at the delivery point.

The handling device, in particular the feeding device, can comprise further components. This can be a separating device that is designed to separate the material blanks from a running and quasi-endless web of material that is supplied. On the other hand, such a component can be a separating device, which separates the material blanks transported in the stream of blanks and thereby forms the mentioned axial distances between the material blanks in the direction of transport.

The handling device, in particular the feed device, can also have a material supply for a running, quasi-endless material web, e.g. a nonwoven fleece web, or for material cuts that have already been separated. On the other hand, the material supply can already be present and not a component part of the handling device, in particular the feed device.

The material blanks can be designed differently. They can each consist of one or more pieces of material. In the case of a multiple arrangement, the pieces of material can be separated from one another. There are a multitude of different possibilities for the formation and shaping of the material blanks.

Further advantageous refinements of the invention are specified in the dependent claims.

The invention relates to a handling device (1) and a handling method for flexible material blanks (2). The material cuts (2) are, for example, nonwoven fleece cuts, preferably made of a textile fiber material.

The handling device (1) is in 1 and 2 shown in side view and top view. It comprises a feed device (7) for individual material blanks (2) and a stacking device (8) connected to the feed device (7). The feed device (7) comprises at least one feed conveyor (11) with a transfer point (12) for transferring the individual fiber cuts (2) to the stacking device (8).

The fiber cuts (2) are fed one after the other in a row in a continuous cut stream (3) at a preferably constant speed. In the stream of cuts (3) they are spaced apart (4) in the direction of flow and conveying.

The individual fiber cuts (2) can, for example, according to 6 be trained. The individual fiber cuts (2) can be in one piece or in several pieces. A fiber cut (2) can, for example, be designed as a single large piece according to the illustration on the right. The left and right representation of 6 show multi-part fiber cuts (2) in a single-row arrangement. In 2 a multi-part fiber blank (2) is shown in a matrix arrangement of its pieces. In 6 a web of material (6) can also be seen, from which, for example, the individual fiber cuts (2) are formed.

The feed device (7) comprises, for example, a transfer conveyor (11) which transports material blanks (2) fed in rows and in the blank stream (3) to the transfer point (12).

The feeding device (7) can include further components. It can, for example, have a separating device (10) and, if necessary, an upstream separating device (31). The separating device (31) can be used to separate a material web (6), in particular a nonwoven fleece web, fed continuously and quasi-endlessly from a material supply (5) into individual material cuts (2). The material supply (5) can be designed as a non-woven plant with e.g. card, non-woven layer and consolidation device or as an unwinding device for a material web (6) or in some other way.

The separated material blanks (10) can then be transported further to the stacking device (8) by a conveyor device (9) in said stream of blanks (3). The transfer conveyor (11) can be part of the conveyor (9). In terms of construction, the parts of the conveyor device (9) can be designed, for example, as belt conveyors.

The feed device (7) can also have a separating device (10) with in which the material blanks (2) separated by the separating device (31) are spaced apart from one another in the conveying direction, forming the spaces (4). The separating device (10) can be formed, for example, by a plurality of individual conveyors of the conveyor device (9) which are arranged one behind the other in the conveying direction and run at different speeds which increase in the conveying direction. Alternatively, other configurations of the separating device (10) are possible.

The material feed (5), the separating device (31), the separating device (10) and the upstream parts of the conveyor device (9) can be part of the feed device (7). Alternatively, they can already be present on site and not belong to the scope of the handling device (1).

The stacking device (8) is designed to form multi-layer stacks (17) of blanks at a stacking point (16) from the material blanks (2) that are fed continuously and preferably at a constant speed to the transfer point (12) and to discharge these stacks (17) of blanks intermittently. The stacking device (8) is designed in such a way that during the removal of a finished stack of blanks (17), the supply of the material blanks (2) and the formation of the stack are not interrupted and preferably also not slowed down.

In the exemplary embodiments shown, the respective stack of blanks (17) is formed on a loose stack carrier (18), which is designed as a pallet, for example. A provision (23) can be provided for the required stack carriers (18), which is designed, for example, as a store and can accommodate and buffer several loose stack carriers (18).

The stacking device includes, among other things, a depositing device (13), a carrier feed (19) and a lifting device (24). It can also include a removal device (26) for a finished stack of blanks (17) and a delivery point (28) for this stack of blanks (17) that has been removed.

The depositing device (13) is designed to temporarily receive the individual supplied material blanks (2) and to place them on a blank stack (17) which is formed at a stacking point (16) on the stacking device (8). The carrier feed (19) is designed to feed a loose stack carrier (18) to the stacking point (16). The lifting device is designed for temporarily and height-adjustably receiving the stack of blanks (17) and the loose stack carrier (18) at the stacking point (16).

3 until 5 illustrate the exemplary design and function of the stacking device (8) and its aforementioned components in an enlarged and broken representation. These are arranged, for example, on a common frame (29) on which the provision (23) and the delivery point (28) can also be arranged.

How 1 clarified, a transporter (30), e.g. a forklift truck, can supply loose stack carriers (18) to the provision (23) and on the other hand, finished blank stacks (17) with their loose stack carrier (18) can be picked up from the delivery point (28) and transported away .

The carrier feed (19) is designed to temporarily receive a new stack of blanks (17) at the stacking point (16), while a previously formed stack of blanks (17) is being removed by the lowered lifting device (24). The lifting device (24) is designed to take over the new blank stack (17) from the carrier feed (19) after this removal.

In the embodiment shown, the new blank stack (17) is formed on a loose stack carrier (18) which is fed from the carrier feed (19) to the stacking point (16). The lifting device (24) can take over the loose stack carrier (18) with the new blank stack (7) formed thereon from the carrier feed (19). During the further stacking process, the lifting device (24) can be lowered according to the growing stack height. The carrier feed (19) freed from the new stack of blanks can be removed from the stacking point (16) and e.g. moved back to the provision (23). There you can record a new loose stack carrier (18).

In the exemplary embodiments shown, the depositing device (13) comprises a revolving conveyor (14) aligned horizontally, in particular horizontally, and an adjusting device (15) which can move the revolving conveyor (14). The adjusting device (15) can reversibly move the circulating conveyor (14) over the stacking point (16) and over the loose stack carrier (18) located here and with a preferably horizontal and linear movement. It is designed, for example, as a controlled driven slide.

The circulating conveyor (14) is designed, for example, as a belt conveyor. He can perform a revolving movement of his preferably endless conveyor belt or other funding. The travel movement and the revolving movement can be superimposed on one another as required. They can be controlled by a controller (not shown) of the handling device (1), in particular the stacking device (8).

The depositing device (13), in particular the circulating conveyor (14), is arranged below the transfer point (12) and below the transfer conveyor (11). At the transfer point (12), for example, the material blanks (2) can be fed obliquely from above onto the circulating conveyor (11).

The carrier feed (19) is arranged below the depositing device (13). You can feed the loose stack carrier (18) to the stacking point (16) below the depositing device (13). The feeding movement can also be linear and horizontal.

The stacking device (8) can include a relative height adjustment (22) between the depositing device (13) and the carrier feed (19). In the exemplary embodiments shown, the height adjustment (22) is arranged on the carrier feed (19). The height adjustment (22) allows the carrier feed (19) to be lowered according to the increasing height of the newly formed stack of blanks, so that the distance between the top stack layer and the depositing device (13) and the depositing conditions for the flexible material blank (2) remain constant.

In the exemplary embodiments shown, the carrier feed (19) comprises a support means (20) and a transport device (21). The support means (20) is e.g. designed like a cantilever and comprises two or more preferably straight support arms which are aligned horizontally, in particular horizontally, and which can be moved by the transport device (21) along their extension to the stacking point (16) and back.

The transport device (21) is designed, for example, as a carriage driven in a controlled manner. This can be located at the staging area (23) and can be arranged, for example, below a staging level for the buffered loose stack carriers (18).

The support arms can comprise gripping means which can be driven in a controlled manner and which can grip and hold a loose stack carrier (18) laterally. The carrier feed (19), in particular the support means (20), is designed to feed a loose stack carrier (18) to the stacking point (16) and to keep it there temporarily and in a floating manner. This can be done at a distance above the lowered lifting device (24) and the finished stack of blanks (17) there.

The depositing device (13) and the carrier feed (19) are arranged opposite one another at the stacking point (16) and can be moved in opposite directions. They can be delivered to and removed from the stacking point (16) in reversing fashion.

The lifting device (24) is also arranged at the stacking point (16). For example, it can have a lifting table (25) which can be raised and lowered by means of lifting means, for example hydraulic cylinders. The movements of the depositing device (13), the carrier feed (19) and the lifting device (24) are controlled by said controller and coordinated with one another. The lifting table (25) can, for example, have the shape of a plate or a rake.

The discharge device (26) is arranged at the lowering position of the lifting device (24). It takes over the finished blank stack (17) with the loose blank carrier (18) from the lifting device (24) and transports it to the depositing point (28). For this purpose, the discharge device (26) can have a separate stack conveyor (27), for example, which is arranged next to the lifting table (25) in the frame (29). The lifting table (25) and the stack conveyor (27) can be structurally and functionally matched to one another in such a way that the stack conveyor (26) moves into the lowered lifting table (25), reaches under and lifts the stack carrier (18) and finally removes it from the lifting table (25). can dissipate. Alternatively, the stack conveyor (27) can grip the stack carrier (18) at the side, for example, and remove it with the stack of blanks (17).

3 until 5 illustrate a stacking process on the stacking device (8) in several steps and operating positions.

3 shows an initial position in which the depositing device (13) and its circulating conveyor (14) are retracted, with the front end of the circulating conveyor (14) pointing towards the stacking point (16) below the transfer point (12) and the front end of a material blank that is available here (2) is arranged. The carrier feeder (19) and its support means (20) with a received loose stack carrier (18) are positioned and suspended at and above the stacking point (16) and below the depositing device (13). The lifting device (24) with a finished blank stack (17) on a stack carrier (18) is in the lowering and removal position. The discharge device (26) can take over the finished blank stack (17) and transport it to the delivery point (28) via an intermediate position shown in dashed lines.

4 shows a later operating position, in which the circulating conveyor (14) was moved by the adjusting device (15) to the stacking point (26) and in so doing received the supplied material blank (2) on its upper side. The circulating conveyor (14) was moved in the same direction and speed as the material blank (2) fed to the transfer point (12). The circulating conveyor (14) performs only a linear and horizontal forward travel movement, the circulation movement is blocked. During this forward travel movement, the circulating conveyor (14) was moved over the loose stack carrier (18) which was held ready and positioned in a floating manner on the support means (20). At the end of the forward movement of the circulating conveyor (14), its front end and the front end of the material blank (2) arranged here are located above the rear end of the stack carrier (18).

4 shows an operating position in which the depositing device (13) and its circulating conveyor (14) have already deposited several material blanks (2) on top of one another and have formed a new stack of blanks (17) on the stack carrier (18).

In the operating position of 4 during the formation of the new multi-layer blank stack (17), the lifting device (24) has removed the previously formed, finished feed stack (17) and then carried out a lifting movement again, with the lifting table (25) under the carrier feed (19) and the support means (20) and the new blank stack (17) is positioned.

4 also shows the end of the process of picking up a single material blank (2) on the depositing device (13) and its circulating conveyor (14). From this position, the subsequent depositing process of the picked-up material blank (2) can take place, with the circulating conveyor (14) performing a linear return movement and at the same time a circulating movement of the conveyor belt, in which the upper belt strand is moved in the opposite direction. Arrows clarify in 4 these directions of movement and also indicate the adjustment device (15).

5 shows an intermediate position during this process of laying down the flexible material blank (2). Its front end area has already been deposited on the new stack of blanks (17) in a rolling motion congruently with the other layers of blanks, with the rear area of the blanks still being located on the circulating conveyor (14). 5 also shows the depositing and rolling movement of the flexible material blank (2) by the superimposed return movement and circulating movement of the circulating conveyor (14).

5 also shows the takeover of the loose stack carrier (18) and the new stack of blanks (17) by the raised lifting device (24) and its lifting table (25). The loose stack carrier (18) has previously been released from the carrier feed (19) and its support means (20). The support means (20) is arranged outside the interfering contour of the lifting table (25).

In 5 the carrier feeder (19) is shown in retracted position at the staging (23). In this position, the support means (20) picks up a new loose stack carrier (18) that is ready and transports it to the stacking point (26) according to FIG 3 , as soon as the blank stack (17) has been completed and lowered by the lifting device (24). The stacking cycle then starts again.

A new and empty loose stack carrier (18) can be fed to the stacking point (16) while an individual material blank (2) is being picked up at the depositing device and on its circulating conveyor (14). The material blank (2) is supported and held by the depositing device (13) until the new stack carrier (18) is positioned at the stacking point (16). He can then in the at 4 and 5 illustrated manner are stored on the stack carrier (18).

A picked-up material blank (2) is deposited by the depositing device (13) at a higher speed and in a shorter period of time than the previous pickup of the individual material blank (2). The return movement and the circulating movement of the circulating conveyor (14) are superimposed. The laying process is matched to the axial length of the distances (4) between the individual material blanks (2). The deposit takes place in the time required for a new and spaced-apart material blank (2) to flow in the blank stream (3) from the in 4 example shown position to the transfer point (12) acc. 3 to get.

Modifications to the embodiments shown and described are possible in various ways.

The depositing device (13) can be designed in a different way, e.g. as a lifting device or as a picker, which grasps a material blank (2) from above and attaches it to the stacking point (16) and the empty stack carrier (18) or a blank stack ( 17) discards. The depositing device (13) can work on the fly and at a speed coordinated with the stream of blanks (3).

The carrier feed (19) can also be designed in a different way. It can, for example, have support means (20) in the form of support arms aligned along the feed direction and laterally spaced from one another, which can move in and out in the feed direction in correspondingly aligned and recessed receiving lanes on the upper side of the lifting table (25). Raised webs can be formed on the lifting table (25) between the receiving lanes, on which in the aforementioned acquisition of the stack carrier (18) with the new Blank stack (17) can rest while the carrier feeder (19) withdraws.

The invention also relates to a modification in which the loose stack support (18) can be omitted. Instead, a stack carrier is attached to the carrier feed (19), in particular to the top of its support means (20). The attached stack carrier can be formed by a flat upper side of the support means (20), in particular by support arms. An attached stack carrier can also have a different shape, e.g. a plate-like shape. The attached stack carrier is designed in the various variants in such a way that it enables the lifting table (15) and the carrier feed (19), in particular the support means (20), to penetrate each other in the vertical direction and also allows a retraction movement of the carrier feed (19) to the Removal from the stacking location (16) allowed. The stack of blanks (17) formed on the attached stack carrier can then be taken over directly by the lifting table (25) on its upper side. Furthermore, the discharge device (26), in particular the stack conveyor (27), can take over the blank stack (17) directly and transport it to the delivery point (28).

The height adjustment (22) can also be modified. Instead of the embodiment shown, the depositing device (13) and possibly also the transfer point (12) and the transfer conveyor (11) can perform an upright lifting movement relative to the carrier feed (19) positioned at the stacking point (16) and to its support means (20). .

Furthermore, different features of the described exemplary embodiments and their variants can also be combined within the scope of the claims to form mixed forms or even interchanged.
