Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a card device, and particularly to a card device having the following frame structure.

In conventional card devices, the main card cylinder or cylinder in case of dual card devices is one
It is mounted on a separate frame body, which is usually made of cast iron.

The high weight of each member makes assembly and repair of such card devices difficult, and the necessity of adjusting each bearing member relative to the frame makes it difficult to accurately position the cylinders.

In U.S. Pat. No. 4,258,453, a main cylinder, a take-in member, and a dosing member are attached to each frame module, which modules constitute a card device. In this way,
Manufacture, transportation, assembly and repair of card devices,
It is simplified depending on the purpose of use of the card device.

For example, changing over the frame modules that support the cylinders is simplified by replacing take-in or dossier members with members designed for special functions. Converting a single cylinder card to a dual card is facilitated as it is only necessary to add an additional module, a second card cylinder and a suitable central roller.

A disadvantage of modular frame construction is that the modules must be interconnected to provide a laterally rigid structure over the entire length of the frame. Lateral stiffness is important in the actual operation of the card device. This problem is not solved by the invention described in US Pat. No. 4,258,453.

The present invention aims to solve such problems and provides a card device equipped with a modular frame having the necessary robustness.

A card device according to the present invention includes a first frame that supports a main card cylinder provided at both ends of the card device, and a second frame that supports a second cylinder that cooperates with the main cylinder. has a generally rectangular cross-section, the ends thereof overlapping each other, and a support device attached to the first frame to support the second frame;
It is characterized by a frame structure consisting of a device for adjusting the distance between the two frames and a device for fixing the two frames together for a laterally rigid structure.

Thus, the present invention provides a modular structure in which the first frame or module supports the main card cylinder.

In addition to the main card cylinder, the first frame is also adapted to be fitted with either a take-in member or a dower member. These two
One of the cylinder members forms another module by being attached to the second frame.

However, preferably the frame structure
It is preferable to include a third frame fixed to the first frame in a manner similar to that of the frame. This third frame is on the opposite side of the second frame and
connected to the frame. In this way, the first frame supports the main card cylinder, the second frame supports the card member, and the third frame supports the take-in member, thereby linking these three basic cylinders. , are adapted to be supported by separate frame modules.

According to the modular structure according to the present invention, by overlapping and fixing the ends of the first frame and the second frame, and if there is a third frame, the ends of the first frame and the third frame, The required robustness can be obtained. Preferably, the side portion of the first frame is the innermost side from the overlapping portion.

A heavy frame is not required. The fixing member is preferably fitted in a direction perpendicular to the side surface. Also, by providing a suitable bearing member between the two overlapping parts, a gap is formed between the frames. All frames may be of hollow construction so that they are significantly lighter than traditional cast frames.

The first frame is supported on the floor. The second frame and the third frame may also have similar structures. However, no floor support is required for either the second frame or the third frame. The second frame and the third frame may be suspended from both ends of the first frame. The first frame may be supported by a subframe attached to the floor. In the support mounting, it is preferable that the first frame is allowed to move with a suitable degree of freedom with respect to the subframe.

In order to support the second frame and the third frame,
The support device on the first frame can be of various shapes, but is preferably a pivot member attached to the first frame.

The second or third frame has a portion that engages the pivot member. This portion may be a pivot bearing pad in the form of a pivot housing or an inverted V-shaped pad that engages the pivot member. Such a structure facilitates assembly of the frame.

The pivot bearing pads may be adjustable for each frame, thereby providing accurate placement of the pivot bearing pads relative to the axis of rotation of the cylinder supported by the frame.

In order to facilitate adjustment of the cylinders supported by the frames, the pivot axes of the second and third frames are aligned with a line connecting this center axis with the center axis of the cylinder attached to the frame.
It is preferable that the cylinder be arranged at an angle of 20° or less with respect to the normal tangent of the cylinder provided on the frame. More preferably, this bond line is approximately parallel to the tangent line.

To create this kind of relationship, set the pivot to the first
Best placed at the bottom edge of the frame. Therefore,
The adjuster is provided at the upper end of the frame. This adjustment may be in the form of a filbow.

The device connecting each frame to each other may be a bolt extending laterally of the frame. Since each frame is a hollow structure, the bolts may be provided with suitable spacers and other fixing elements.

In order to better understand the card device according to the invention, preferred embodiments of the invention will be described below with reference to the accompanying drawings.

In the drawing, only one side of the card device according to the invention is shown. The opposite side has a similar structure and is therefore omitted from illustration.

The first frame 6 supports a bearing 7 for the main card cylinder. A portion of this main card cylinder is shown as 8 in dashed lines.

The card cylinder is connected between each of the first frames 6 provided on two sides of the card device. By allowing some pivoting movement of the first frame relative to the subframe, no stress is transmitted to the frame.

A second frame 9 is provided at one end of the first frame 6, and a third frame 10 is provided at the other end. The second frame 9 is provided with a bearing 11 for the take-in member 12. This take-in member 12 extends between the second frames 9 provided on the two sides of the card device. The third frame 10 supports a bearing 13 for a dossier member (not shown). This dotted member is a third frame 1 provided on both sides of the card device.
It extends between 0 and 0.

As shown in the figure, the second frame 9 and the third frame 10 have similar structures, so the third frame 1
Only 0 is shown in detail.

The first frame 6 is hollow and has a substantially rectangular cross section. In FIG. 2, two side plates 14 and 15 are shown.
A first frame 6 is shown having . This 2
A connecting plate 16 that supports the pad bearing 5 extends between the side plates 14 and 15. Side plate 1
A reinforcing member 17 is further provided between 4 and 15. The top end of the frame is formed by the upper plate 21a.
Most of the width is occluded.

A bearing 7 is mounted on the upper plate 21a. This upper plate 21a has a recess cut at the end of the frame. A protrusion 18 is provided at the lower end of each side plate 14,15. This protrusion 18
A pivot rod 19 supported by the side plates 14, 15 extends between and projects outwardly.

The frame 10 has a hollow, substantially rectangular cross-section with side plates 20, 21 connected by a top plate 21a. This cross section is made to fit around the sides of the first frame, as shown in FIG.

The outside of each side plate 20, 21 of the third frame 10 is provided with a pivot bearing pad 22, 23 having a circular hole for receiving the pivot rod 19, respectively. The side plates 20,21 are cut behind the pivot bearing pads 22,23 to form an aperture in the bottom of the side plates. As a result, side plate 2
0 and 21 fall into appropriate positions on the pivot rod 19.

Pivot bearing pads 22, 23 are attached to the side plates 20, 21 at predetermined locations and hold the rod 19. Each bearing pad 22, 23 is provided so as to be adjustable with respect to each side plate 20, 21 by means of an adjustment bolt and a hole 24, and is fixed at an appropriate position after adjustment.

The second frame 9 differs in that the pivot rod is inserted into a bearing pad having an inverted V-shaped notch 25 instead of a circular hole.

By adjusting the pivot bearing device, 2

Before the third frame 10 is attached to the first frame 6, neither the bolts 29, 30 nor the adjuster 26 are provided. 2 third frames 1
0 and the dotted member provided therebetween are lifted to a position such that the end of the third frame 10 moves over the end of the first frame 6, and the pivot bearing pads 22, 23 are placed in the dotted part. The end of the pivot rod 19 is adjusted relative to the axis of the pivot rod 19 and fixed in place.

The adjuster 26 is then adjusted to connect the two frames and provide the necessary attachment between the tips of the teeth on the main card cylinder and the doss member.

The two spacers 31 and 32 each have a first inner wall surface.
Until it comes into contact with the outer wall surface of the side plate 15 of the frame 6,
It is screwed into a screw hole provided in the side plate 21. Such contact causes side plates 14 and 20 to contact each other, while side plates 15 and 21 are separated by a desired small distance.

The two frames are arranged parallel to each other.
Next, spacers 31 and 32 are attached to side plate 21 so that they do not rotate relative to each other. Preferably,
It is preferable that the spacers 31 and 32 be fixed at appropriate positions by pinning. Bolts 29 and 30 are

The pivot bearing pads 22, 23 are arranged in such a way that the line joining the rotating shaft and the shaft of the implant is 20° or less, preferably parallel to the tangent between the main cylinder and the implant cylinder, relative to the implant member.
It is good to place it. A similar relationship is made on the side of the take-in member. This is shown in FIG. A line A-B connecting the center axis of the pivot member and the center axis of the pivot is substantially parallel to a line CD, which is a tangent between the main cylinder and the pivot member.

The frame structure made in this way can reduce the construction cost and simplify the assembly method. The second and third frames are
For each roller it has a surface attached to a bearing housing. All frame members have the effect of removing dust.

It should be noted that the drawings merely show one embodiment of the invention and that frame structures different from those shown are possible.

A structure in which the frames of each pair rotate relative to each other is not necessarily required. The ends can be supported by simple bearing pads supported by the main frame. With this arrangement, the bearing pads are adjustable upwardly and downwardly of the main frame. On the other hand, adjustment devices provided longitudinally in the main frame, at both the upper and lower ends,
It is provided between the main frame and the end frame. Although other adjusters may be used, adjusters constructed as in the present invention are particularly preferred.

The end of the first frame is provided inside the overlapping end of the second frame and the third frame, but conversely, the end of the second frame and the third frame are provided inside the overlapping ends of the second frame and the third frame. It can also be installed inside.

Methods other than those shown in FIG. 2 can be used to bolt the two frames together to provide the necessary strength to the overall structure.

In another embodiment, the outwardly facing planes on each side of the inner frame are aligned with the outer sides of the inner frame by welding or otherwise attaching bearing pads with opposing planes to the side plates of the frame. It contacts the inwardly facing planes on both sides of the frame, and due to this contact relationship,
The two frames are now in proper contact with each other. In order to secure the frames to each other, the bolts may be provided via bearing pads.

The method for attaching the end frames to each end of the central main frame need not be the same for each end frame, and other methods may be used to suit the special requirements of the cylinders supported by the end frames. You can choose.

Additional frames may be concatenated with the second frame and/or the third frame.

This additional frame can support other parts of the carding device, such as a pre-taken member, a feeding device, a web take-off device. The connection state between such additional frames and adjacent frames is similar to the relationship described above.

The above embodiment describes one aspect of the present invention, and many other modifications are possible without departing from the scope of the claims.
