Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a lap supply device for supplying wrap discharged from a lap forming machine to a next step.

[Conventional technology]

In a severe environment, spinning mills are always making efforts to save labor, and in the combing process, how to efficiently transport wraps from a wrap forming machine to a combing machine is a major technical issue.

Conventionally, in this type of transportation, the wrap discharged from the wrap forming machine is transported by a worker using a transport vehicle. At that time, in order to improve the workability of the comba machine operator in the limited space, and to secure the lap transport and the transport path of the comb-lifting cans, various arrangements were made regarding the layout of the comba machine. .

Therefore, in order to clarify the problem to be solved by the lap supply device of the present invention, first, the layout of a conventional comba machine in a factory building and the accompanying problems will be described with reference to FIGS. This will be described below. In addition, the upper part of each of FIGS.
However, the relationship between the lap supply device 20 and the layout of the comber will be described later in the section of the embodiment.

The layout of the comber shown in FIG. 4 is an arrangement generally performed. In the figure, reference numeral 16b denotes a wrap on a combing machine, and K denotes a cut end of the wrap. Wrap 16 as known
When the b is placed on the combing machine, the cut K is formed in the combing section (not shown) of the combing machine so that the cuts K of the laminated and coiled wrap sheet are sequentially rewound on the wrap supply section of the combing machine. ). The cut end K shown in FIGS. 4 to 7 has a sheet leading end at the position indicated by K of the coil-wrapped wrap sheet, and is continuous from the position of K perpendicular to the paper surface and below the paper surface. The winding direction of the wrap sheet is shown as an extended state. On the other hand, in the conventional combing machine, the comber unit 18 for combing the sliver obtained by adding doubling and drafting to the can into a can is arranged to face the passage in the factory building. Wrap 16 on board
Two types of combers are provided, a comber 17R on the right side and a comber 17L on the left side with respect to the row b. In the layout of the comber shown in FIG.
Since the wrap row of R and the combing machine 17L faces the passage between the combing machines 17R and 17L, there is an advantage that it is easy to transport the wrap 16b to the combing machine and carry out the sliver can,
In order to align the cut K of the wrap 16b with the combing section, when placing the lap 16b on one of the combers 17R and 17L, it is necessary for the operator to perform an operation of inverting the wrap 16b.

Therefore, as shown in FIG. 5, if a plurality of combing machines 17R are arranged on the left side and a plurality of combing machines 17L are arranged on the right side in the factory building room, the cut end of the wrap 16b on the wrap supply section of the combing machine is fixed. The wrap 16b can be aligned in the direction, and the work of reversing the cut K of the wrap 16b when the wrap is transported to the combing machine can be eliminated.

On the other hand, in recent combing machines, only one of the R and L units may be manufactured due to problems such as parts management. In this case, for example, a plurality of combing machines are arranged in a layout as shown in FIG. ing. In this case, cut the lap K
Are not aligned between the combing machines, so that the cuts K of the wrap 16b can be aligned in one direction by adopting the layout shown in FIG.

By arranging the combing machines in the layout shown in FIG. 5 or FIG. 7, there is an advantage that the cuts K of the wrap 16b are aligned in one direction and automatic conveyance of the wrap can be easily performed. However, re-installing the combing machine from the layout shown in FIG. 4 or FIG. 6 has a problem in that the production of the combing machine is interrupted and a problem in cost. Also, if the layout of FIG. 5 or FIG. 7 is adopted when the existing factory is re-installed, it becomes difficult to secure a can passage for cans. In addition, if this layout is adopted in a new factory, it is necessary to increase the floor space. Therefore, the layout shown in FIG. 5 or FIG. 7 is a preferable layout for lap cutting, but is not realistic from the viewpoint of floor space.

As described above, there are various types of layout of a comber machine in a factory building, and a wrap supply method that can cope with these various types of layouts is demanded.

Conventionally, the wrap is transported from the lap forming machine to the combing machine by receiving the wrap discharged from the wrap winding section of the lap forming machine by the wrap supply device, and transporting the wrap from the wrap supply device to the wrap supply portion of the combing machine by a transport vehicle. Is going. The wrap supply device includes a wrap moving device that moves the wrap received from the wrap winding unit, and a lap stock device that receives the wrap from the wrap moving device and temporarily stores the wrap.

There is yet another problem with wrap transport, namely the height of the wrap during transport. Generally, the lap discharge position of the lap forming machine does not coincide with the height of the lap supply section of the combing machine. In consideration of the convenience of placing the lap on the combing machine, the height of the transport vehicle is generally adjusted to the height of the wrap supply section of the combing machine. The height of the lap stock device of the lap supply device is adjusted to the height of the lap carrier. However, depending on the comber, the difference between the height of the wrap supply unit and the height of the wrap stock device is large (the wrap supply unit of the comber is at a high position). Therefore, the height that the wrap stock device can supply was at most 500 mm, and the capacity was lower than the size of the device.

On the other hand, the lap forming machine is affected by the height of the lap moving device of the lap supply device because the lap is discharged to the lap supply device. Therefore, if the height of the machine on the upstream side (with respect to the flow of the lap) including the lap forming machine is increased, the lap is difficult for short workers (generally, girls are working). Various operations such as charging an empty bobbin into an empty bobbin return port on the forming machine have been difficult. Therefore, it is preferable to reduce the height of the lap forming machine, and for this purpose, the height of the lap supply device must be reduced, so that a part of the lap supply device is installed at a position lower than the floor. Although the work has been considerably improved by this, not only the maintenance work under the lap supply device has become difficult, but also the floor has to be dug when the lap supply device is installed, and the installation work cost has been increased. Thus, the appropriateness of the height of the wrap causes various problems.

Therefore, a device for adjusting the height of the lap is demanded, and one example thereof is disclosed in Japanese Utility Model Publication No. 63-38207. In this device, a moving body is arranged between a pair of upper and lower frames arranged at intervals, and a moving body such as a chain mounted on the pair of frames and the moving body is moved to move the moving body. The lap holder is moved up and down between a pair of upper and lower frames, thereby moving the wrap receiver connected to the moving body through the upper frame up and down. The lap can be moved up and down using this device, but the lower limit of the height of the wrap receiver is high due to its mechanism, and the existing lap feeder,
And it cannot correspond to a combing machine.

On the other hand, the lap discharged from the lap moving device of the lap supply device is received on a belt conveyor, and the lap is supplied for one comber machine or 1 /.
2. Description of the Related Art A lap stock apparatus that transports two wraps above a combing machine is known. However, this lap stock apparatus does not have a device for aligning the lap, i.e., changing the axis of the wrap by 180 DEG. Therefore, it can be used for the comber machine group having the layout shown in FIGS. 5 and 7, but it can be used for the comber machine group shown in FIGS. 4 and 6 having a practically preferable layout. Can not.

Therefore, in order to use the above-mentioned lap stock apparatus also for the comber group having the layout shown in FIGS. 4 and 6, a method of rotating each of the laps of one or a half of the comber by 180 ° is used. Conceivable. However, in this case, the number of lap turning devices increases and the cost increases, and the arrangement pitch between the laps needs to be wide so that the wraps do not interfere during the turning. In addition, the entire lap stock device is 180
゜ A method of turning is also conceivable, but the device itself becomes large and there is a problem in cost.

In addition, the wraps used in combing machines are becoming larger and heavier. For this reason, there is a problem that the processing of the heavy wrap imposes a burden on the operator and the surface of the wrap is disturbed by the operator's hand.

[Problems to be solved by the invention]

As described above, the conventional method of transporting the wrap from the lap former to the comber has various problems.

The present invention can cope with any layout of a combing machine, and has the following three problems, namely, problems relating to the work of a worker using a transport vehicle, problems relating to lap cutting, and problems relating to lap height. It is an object of the present invention to provide a wrap supply device capable of solving points in a comprehensive manner.

[Means for solving the problem]

The above object of the present invention is to provide a wrap stock apparatus which prepares for transporting a wrap from a vicinity of a lap forming machine to an apparatus of a next process; and A lap moving device for moving the wrap discharged from the forming machine from the lap discharging position of the lap forming machine onto the lap stock device with its axis set in a predetermined direction, wherein the lap moving device rotates in a horizontal plane. A movable turntable, a drive mechanism for driving the turntable, a wrap holding member configured to be able to lift a wrap on the turntable from outside the turntable, and a plurality of vertically moving wrap holding members. Discharging from the lap forming machine, comprising: a lifting mechanism comprising a link mechanism; and a drive mechanism for moving the lifting mechanism left and right. The-up is accomplished by supplying wrap feeder to the next process.

Since the lap supply device of the present invention includes a turntable rotatable in a horizontal plane, the axis of the lap can be rotated by 180 ° as needed, thereby making it possible to align the cut edges of the lap. For this purpose, it is preferable that the turntable driving mechanism is configured to be rotatable by a command signal.

Since the wrap supply device of the present invention includes the lifting mechanism for lifting the wrap, the wrap can be raised to a required height without requiring the labor of the operator. Also, since the wrap holding member constituting the lifting mechanism is configured to lift the wrap from the outside of the turntable, there is no risk of disturbing the surface of the lap, and the lap holding member is moved up and down by a plurality of link mechanisms, so The vertical movement position can be changed over a wide range.

Preferably, the lap stock device is a conveyor, and the conveyor can be driven intermittently by a command signal. By configuring the lap stock apparatus in this way, the wrap arrangement on the conveyor can be adjusted to the position of each combing station of the combing machine.

〔Example〕

The present invention will be described in detail below with reference to the accompanying drawings showing an embodiment of the wrap supply device of the present invention.

FIG. 1 shows an example of the wrap supply device of the present invention, and FIG.
FIG. 1 (A) is a perspective view showing an overall view of the wrap supply device, and FIG. 1 (B) is a front view showing a mechanism for moving the wrap hidden and invisible in FIG. 1 (A) vertically and horizontally. Indicated by FIG. 2 is a drawing mainly showing a turntable and a drive mechanism for cutting the lap necessary for operating the lap supply device of the present invention, and FIG. 2 (A) is a perspective view, FIG. 2 (B) is a front view thereof.

As shown in FIG. 1A, the wrap 16a is discharged from the wrap winding section 15 to the turntable 1. Wrap winding unit
The cut edges (not shown) of the wrap 16a discharged from 15 are all the same. That is, the winding direction of the wrap web spirally wound from the winding end end of the wrap toward the inner layer of the wrap is the same. As described above with reference to FIGS. 4 to 7, depending on the arrangement of the combing chambers of the plurality of combing machines, the wrap 16a is displayed on the conveyor 14 while the wrap 16a is discharged from the wrap winding section 15. 16b on top
Comb machines and wraps 16 that can be arranged as shown
It may be necessary to rotate a by 180 ° about its axis to reverse the winding direction of the wrap web in the wrap 16b and place it on the conveyor.

Therefore, in the wrap supply device 20 of the present invention, the wrap winding section 15
The wrap 16a discharged from the hopper is first received on the turntable 1 rotatable about the vertical axis 2a. The upper surface of the turntable 1 is preferably formed in a concave shape so as to stably receive the wrap 16a having a circular cross section. The rotation of the turntable 1 is performed by rotating the vertical shaft 2a of the turntable 1 with the gear 2
Is fixed, and the rotary actuator 4 having the gear 3 meshing with the gear 2 is driven. At this time, it is preferable that the rotary actuator 4 be configured to be able to rotate either rightward or leftward by a command signal from the outside.

Each time the wrap 16a is adjusted to the cut necessary for the combing machine every time it is supplied, the wrap 16a shown in FIG.
Is placed on the conveyor 14 as shown in FIG.

Next, a mechanism for moving the wrap in the vertical and horizontal directions will be described with reference to FIG.

In order to lift the wrap 16a whose cut end is aligned in a predetermined direction as described above, in the embodiment shown in FIG. 1, the wrap 16a is arranged so that it can be lifted from both sides of the turntable 1. A wrap holding member composed of a pair of plates 5, 5 'is used (see FIG. 1A). Therefore, the width of the plates 5, 5 'constituting the wrap holding member is set smaller than the diameter of the wrap used.

It is preferable that the upper surface of the turntable 1 and the upper surfaces of the plates 5 and 5 'of the wrap holding member are substantially flush with each other when the wrap is taken out from the wrap winding portion 15 onto the turntable 1.
However, in such an arrangement, the turntable 1 cannot be rotated. Therefore, in the apparatus of the embodiment shown in FIG. 1 of the present invention, a vertical moving mechanism for lowering the wrap holding members 5, 5 'when rotating the turntable 1 is used.

Therefore, in the apparatus of the embodiment shown in FIG. 1, as a mechanism for moving the wrap up and down and in the lateral direction, each of the mechanisms has an air cylinder, and three mechanisms which are all connected by a link mechanism, namely, a turntable 1 At the time of rotation, the wrap holding members 5, 5 'are lowered from the position corresponding to the turntable 1, and the turntable 1 is returned to the original position after rotation (using the first air cylinder 11). The wrap holding members 5, 5 'are lifted in order to raise the wrap 16a to the wrap position indicated by 16b slightly above the conveyor 14 and then the wrap holding member
A mechanism (using the second air cylinder 8) for returning the 5,5 'to the original position, and a lap holding member 5,5' in the horizontal direction from the position corresponding to the wrap winding portion 15 toward the position above the conveyor 14. And then return the lap holding members 5, 5 'to their original positions (using the third air cylinder 12). Since the three mechanisms are integrally formed as shown in FIG. 1 (B), the three mechanisms will be described together.

In FIG. 1 (B), reference numeral 10 denotes an air cylinder mounting plate. At a fulcrum G at the lower end of the air cylinder mounting plate 10, a substantially central portion of the first air cylinder 11 is rotatably supported. The tip of the piston rod 11a of the first air cylinder 11 is rotatably mounted on the second air cylinder mounting lever 9 at the fulcrum F, and the upper end of the mounting lever 9 is pivotally mounted on the air cylinder mounting plate 10 at the fulcrum E. . Second air cylinder 8
A substantially central portion is rotatably attached to a substantially central portion of the mounting lever 9 at a fulcrum D. On the other hand, one end of the third air cylinder 12 is rotatably attached to the frame 13 at the fulcrum I, and the piston rod 12 of the third air cylinder 12
The tip of a (see FIG. 3 (D)) is rotatably mounted on the air cylinder mounting plate 10 at the fulcrum H.

Next, the lap holding members 5, 5 'are rotatably connected to the link lever 6 at the fulcrum A via rods 6a, 6b, respectively. The lower end of the first link lever 6 is connected to the second air cylinder 8 at the fulcrum C. It is rotatably connected to the tip of the piston rod 8a. Further, the tip of the second link lever 7 is rotatably connected to a fulcrum B at the center of the link lever 6, and the rear end of the second link lever 7 is rotatably attached to the air cylinder mounting plate 10 at the fulcrum J. . Note that the fulcrum E, the fulcrum J and the fulcrum C are on the same horizontal plane. Only the fulcrum I among the fulcrums is a fixed position on the frame 13, and the other fulcrums move with respect to the frame 13. On the other hand, the air cylinder mounting plate 10 is configured to be slidable in the horizontal direction with respect to the frame 13.

The width of the conveyor 14 must be narrower than the distance between the pair of plates 5, 5 'of the wrap holding member, as shown in FIG. 1 (A). Also, the lateral movement direction of the wrap holding member needs to be parallel to the movement direction of the conveyor 14 and to match the center line of the conveyor 14 with the center line of the turntable 1.

As shown in FIG. 1 (B), the lap supply device 20 of the present invention has a feature that the height of the lap supply device can be reduced because it is configured using a link mechanism.

Next, FIG. 2 (A), FIG. 2 (B) and FIG. 3 (A)

At this time, the wrap 16b on the wrap holding member is placed on the conveyor 14.

Next, by operating the piston rod 12a of the third air cylinder 12 to retract (not shown), the air cylinder mounting plate 10 and the wrap holding members 5, 5 'are returned to the positions shown in FIG. 1 (B). As a result, one cycle of the lap movement is completed, the lap holding members 5, 5 'are located at positions where the upper surfaces thereof are aligned with the upper surface of the turntable 1, and the next lap is discharged from the lap winding section 15. It will be in a state of waiting for it.

A plurality of wraps can be arranged on the conveyor 14 by sequentially repeating the operations shown in FIGS. 3 (A) to 3 (E). At this time, the conveyor 14 may be configured to be driven intermittently by a command signal so that a plurality of wraps can be arranged on the conveyor 14 at predetermined intervals, more specifically, at intervals of a combing station of a combing machine.

The lap supply device 20 of the present invention can be used for combers having various layouts shown in FIGS.

〔The invention's effect〕

In the lap feeder according to the present invention, workability is improved because the entire machine can be set low, and it is not necessary to dig a floor, so that it can be installed in any factory (for example, the second floor). Not only can the cost be reduced, but also the wrap can be moved from the position where it is discharged from the wrap take-up section onto the conveyor, and the axis of the wrap can be rotated by 180 ° if necessary, and these two movements can be performed. Are integrally configured. Therefore, by using the lap supply device of the present invention, the lap supply can be performed in accordance with the arrangement of the combing machine without separately using a conventionally known device for rotating the axis of the wrap by 180 °. And is very useful in the space for disposing the device used for supplying the wrap.

Further, the arrangement of the combing machines is devised so that a larger number of combing machines are arranged in consideration of securing a can carrying path or the like in a predetermined space. As a result, combing machines using wraps having different cut-out directions, that is, wrapping directions, may be mixed in a predetermined space. Even in such a case, if the lap supply device of the present invention is used, wraps having a predetermined cut direction can be supplied to all the combing machines, and as a result, a predetermined space can be secured while securing a space for can transport. More combing machines can be arranged within.

From the viewpoint of the lap supply device of the present invention, if the axis of the lap cannot be rotated by 180 °, two lap supply devices can be processed by one lap supply device. This is also very useful in terms of cost and space for disposing the wrap supply device.
