Description

[Detailed description of the invention] This invention relates to a sheet dividing winding machine that divides a wide sheet into multiple strips using a slitter, distributes them to winding positions on both sides, and winds the distributed sheets onto respective winding shafts. The purpose is to eliminate the need to rearrange and change the connections of the power supply wires to each winding head and the compressed fluid hoses that move each time the width changes.

The dividing winder divides a wide raw sheet into several pieces using a slitter and winds them up as sheets of the required width.
Therefore, each pair of winding heads that support and rotationally drive both ends of the winding core to wind each divided sheet change their position each time the dividing width is changed. For example, when dividing the sheet width into 12 parts using a sheet dividing winder with 24 winding heads, six pairs (12 winders) on each side, the winding heads used are on one side. Only one pair per side, and five pairs per side (10
A total of 20 winding heads will be evacuated to positions where they will not get in the way. As a result, the long electric wires and hoses that connect each winding head to the power source and pressure source interfere with preparation work, and when moving, they can get caught on other parts and be damaged, or come into contact with rotating parts, making it difficult to organize them. For this reason, recently there has been an increasing number of methods in which the winding head is placed in the desired position and then connected to a nearby power source or pressure source installed at multiple locations using short electric wires or hoses. In this case, a new connection change operation is required, which can lead to malfunctions such as incorrect connections or forgotten connections, and furthermore, this has become an obstacle in automating the preparation work for changing the dividing width.

This idea goes back to the previous time, and a long electric wire was attached to each winding head.
Attaching a hose made it unnecessary to change connections. Each electric wire and hose is curved into a horizontal U-shape along the sliding direction of the winding head, and neatly arranged by support frames arranged outward in sequence.
Moreover, the folded curved portion can move freely to respond to the movement of the winding head.

Next, the configuration and implementation of this invention will be explained with reference to the drawings.

FIG. 1 shows an example of a sorting type dividing winder to which this invention is applied. A wide sheet S is divided by a slitter C, distributed to the left and right as it passes around a stationary touch roller B, and wound onto winding shafts A held at the ends of the arms of winding heads 1 on both sides, respectively, to form sheet rolls R.

Each winding head 1 is placed on the respective underframe 1a and the rail 3
slide on top. The problem of this invention is how to support the long electric wires or hoses 2 that connect each underframe 1a and the power sources and pressure sources provided at several locations along the rail 3. It should be noted that the power source and pressure source referred to here refer to a branch part of the main wire and pressure fluid pipe along the rail 3, to which the winding head wire or hose 2 can be connected.

Now, to give an overview of this invention with reference to FIGS. 2 to 5, it consists of rails 3 in the sheet width direction provided at the winding positions on both sides of the distribution, and the rails 3 above.
A winding head 1 is mounted movably in the width direction of the sheet, and is provided in plural pairs on each side (three pairs on one side are shown in FIG. 2) so as to support the winding shaft A in pairs. , an arm 4 dedicated to each underframe, whose one end is fixed or engaged with the underframe 1a of each winding head 1 and moves together, and whose direction is aligned approximately at right angles to the rail 3 on the corresponding side; Below, along the rail 3, a common support member 5 is provided with a width commensurate with the arm 4, one end is fixed to one of the arms 4, the other end is fixed to the common support member 5, In the middle, there is a flexible left side support frame in one plane (three on the left side in Fig. 3) that has a folded curved part that bulges leftward, and one end is attached to the right side of the arm 4 to which the left side support frame is fixed. It is fixed to the arm in which it is located, and the other end is fixed to the common support member 5, and at the same time, a folded curved part that bulges to the right is formed in the middle, and is flexible in one plane and is provided in the same row as the left side support frame. The right side support frames (in Fig. 3, the three right side support frames provided in the rows corresponding to the three left side support frames) are one set, and this set of support frames is attached to the winding head 1. Each support frame 6 is provided with a plurality of sets (three sets in Fig. 3) of electric wires and hoses on each side, corresponding to the number of wires and hoses.
is a sheet dividing winder that bends and stretches within each space and is installed so as not to interfere with each other.

In this embodiment, in order to avoid placing an extra burden on the winding head 1 side, the arm 4 is not fixed to the underframe 1a, but only one end thereof is engaged. Even so, the arm 4 remains perpendicular to the rail 3 and the underframe 1
Since it has a unique structure so that it moves together with a, this will be explained with reference to FIGS. 4 and 5.

In this case, the arm 4 connects the lower end of both end plates 4a to the arm plate 4b.
It is a composite arm in which the upper part is connected with a connecting rod 4c. Wheels (rollers) are installed on both sides of the upper outer surface of the end plate 4a.
Two gears 7 are pivotally supported in parallel, and a small gear 8 is attached to the center of the bottom.

Both wheels 7 and small gear 8 attached to the outer surface of both end plates 4a
However, the structure is such that the entire arm 4 is moved parallel to the rail 3 while always keeping it perpendicular to the rail 3 by holding the guide horizontal rack rod 9 (rack teeth facing downward) from above and below, which are attached to the side of the rail 3 and the stationary member facing it. It is. The engagement between the arm 4 and the underframe 1a is achieved by fitting the downward U-shaped groove of the U-shaped member 10 hanging from the lower surface of the underframe 1a into the connecting rod 4c of the arm 4. 11 is a restraint collar.

One end of the flexible support frame 6 is fixed to the lower surface of the arm plate 4b of the arm 4 with a bolt/nut or the like. As can be clearly seen in FIG. 3, its position is different from that of the other support frames 6.

The common support material 5 is a board material of the required width laid along the entire length of the rail 3, but it may also be a crosspiece.
In short, it is sufficient as long as it can receive and support the lower surfaces of all the flexible support frames 6 that are bent and stretched side by side. In this embodiment, holes are made in some places, and electric wires and hoses are brought out from the holes and connected to a power source and a pressure source.
In addition to attaching the lower end of the support frame 6 directly to the top surface of the support material 5, it may be attached to other mounting materials as long as it does not prevent the lower horizontal portion of the support frame 6 from resting on the top surface of the support material 5. .

The flexible support frame 6 can store or restrain the electric wires and the hose 2, and any structure is acceptable as long as it can be used to be flexible in one plane, that is, to curve along one plane. 6th to 9th
The figure shows three examples.

The ones in Figures 6 and 7 are elastic steel strips 12 with electrical wires and hose holding bands 13 attached at random.The steel strips 12 are strong enough to not bend unless intentionally bent, so they can be used in one plane. This is an example of flexibility.

In the one shown in FIG. 8, a holding band 13 is attached to a chain-like link 14. A protrusion is attached to the end of the link so that it bends inward but not outward. The one in FIG. 9 is an example using a commercially available in-plane flexible duct.

By making the flexible support frame 6 flexible in one plane, even if only its upper end is moved, the horizontal U-shaped folded curved portion is maintained.

The method of attaching the flexible support frame 6 is as shown in this embodiment, in which all the winding heads 1 are divided into two groups from the center of the rail 3 to the left and right, and each winding head 1 is moved from the center of the rail 3 to the end. It is advisable to attach the support frame 6 so that it is possible to do so. The rail 3 is extended in both directions beyond the width of the winding machine, and winding head standby positions are provided at both ends of the rail 3.

In this way, the support frame 6 can be relatively short. As can be seen in Figures 2 and 3, among the six winding heads 1 arranged on the left and right, the three winding heads 1 on the left side are supported with a folded curved part that bulges out to the left. A frame 6 is provided so that the rail 3 can be moved from the center to the left end, and a support frame 6 is provided on the three winding heads on the right side with a folded curved part that bulges toward the right. It is possible to move from to the right edge. In the support frame 6, a left side support frame and a right side support frame corresponding to a pair of winding heads located at the center are set as a set of support frames, and the right side winding of a pair of winding heads located at the left side is arranged in the same row. The left side support frame corresponding to the winding head and the right side support frame corresponding to the left side winding head of the pair of winding heads located on the right side are set as a set of support frames, and the pair of winding heads located on the left side are placed in the same row. The left side support frame corresponding to the left side winding head of the pair of winding heads located on the right side and the right side support frame corresponding to the right side winding head of the pair of winding heads located on the right side are arranged in the same row as a set of support frames. Therefore, in this embodiment, three pairs of winding heads and three pairs of support frames are provided for each side of the distribution. The movable distance of the winding head 1 is determined by the position of the fixed end on the receiving material 5 side and the length of the support frame 6.

Note that when the horizontal arms 4 are extended from the underframe 1a in the form of a cantilever beam instead of the embodiments shown in FIGS. 4 and 5, the lengths and heights thereof may be different. The height of the receiving surface of the common receiving material 5 may also vary depending on the height of the horizontal arm 4.

Above, we have mainly explained one embodiment, but
This idea is to attach a dedicated horizontal arm to each of the many winding heads of a split winder, and to this arm, one end of a flexible support frame for electric wires and hoses is fixed at a different position from the other arms. When the is moved together with the winding head, its flexible support frame in one plane always maintains a horizontal U-shaped folded curve on the common receiving material and bends and stretches, and there is a risk that the support frames of all the winding heads may interfere with each other. It was designed to move in an orderly manner without changing its gist, and there is a lot of room for changes and applications based on the well-known techniques of the designer who implemented it.

The applicable split winding machines are limited to those shown in Figure 1, as long as each winding head can be freely adjusted to move in the sheet width direction, and the winding width and number of windings can be changed. do not have. For example, if two touch rollers B are lined up and each one is used for the entire width, or if each sheet roll has an individual touch roller and the contact pressure of the touch rollers is controlled, a special arm is attached to each take-up head frame. You can apply this idea by attaching . The wide sheet feeding direction is also not from below.
Some are from above.

Further, regarding the usage of the flexible support frame 6, in addition to the case in which the horizontal U-shaped curved portion is in a vertical plane as in the above embodiment, it can also be used so that it is in an inclined plane or a horizontal plane.

Note that the support frame may be for one or both of the electric wire and the hose.

This idea solves the confusing problem of attaching electric wires and hoses that can move across the width of the winder to each winding head of a split winder, but connects short electric wires and hoses after positioning the winding head, as in the conventional method. It is not a method of holding electric wires in a coiled form used in machine tools, etc., nor is it a method of folding or stretching electric wires or hoses, but rather holds them in a horizontal U shape and moves one end with the winding head. We adopted a method to do so. For this reason, we used an electric wire and hose support frame to provide flexibility in one plane, so simply engaging the end of the support frame with the winding head allows
The electric wire and hose follow the winding head while constantly moving the horizontal U-shaped curved part.

Therefore, not only does it not cause any confusion, but all of the horizontal U-shaped flexible support frames can be operated without mutual interference by simply attaching one end to an arm at the same height dedicated to each winding head. Further, since the structure can be extremely simple within a minimum space, the space occupied by the winding machine does not increase due to the support frame.

Furthermore, the winding heads can be brought close to each other at close range, thereby allowing various positioning to be performed. Therefore, it is possible to provide a sheet dividing winder that can sufficiently cope with various changes in sheet dividing width from wide to narrow.
