Description

[Detailed description of the invention] The present invention relates to a card device.

In conventional card devices, the flat part of the card device is brought as close as possible to the main card cylinder, that is, the gap between the tip of the protrusion of the flat and the tip of the protrusion of the cylinder is made as small and as possible. Smoothening is highly desirable. Although such purpose was well known, 3.63X:10-'l (1/7
It was not possible to operate the card device in smooth conditions below 000 inches). Technical problems associated with such small gaps include, for example, the need to measure the flat to cylinder wire tip distance as accurately as possible, and the fact that bearings in curved areas must be able to accurately measure the surface of the cylinder wire relative to the cylinder surface. It is to be established. Since the surface of the bearing moves along the curve of the main cylinder, it is the surface of the bearing in the curve that supports the flat end.

SUMMARY OF THE INVENTION An object of the present invention is to provide a card device having a curved member that can be easily attached to the card device in a precise and close manner and that solves the problems associated with conventional devices.

The conventional curved member structure includes a fixed curved section supported by the frame of the card device and a flexible curved section attached to the fixed curved section, and the flexible curved section has a flat end that moves. A bearing has an outer peripheral surface that forms a surface. Both the fixed curve and the flexible curve are provided concentrically with the main card cylinder, and the flexible curve is
At a plurality of angularly spaced points around a fixed curve,
It is radially adjustable. That is, the degree of concentricity of the flexible curved portion can be adjusted. However, achieving as close a connection between the flat and the main cylinder as possible during short-term operation of the card device presents a very difficult technical challenge for those skilled in the art.

According to the present invention, the main card cylinder and the side plates provided on both sides of the card cylinder are provided, and the side plates allow the outer peripheral bearing to be arranged into a plurality of separated peripheral bearings each having a surface and arranged adjacent to each other in a circumferential manner. An adjustable curved member is supported, and each curved member has a bearing such that the end of the surface is
The bearings of the adjacent members are adapted to abut the ends of the surfaces, and further provided with means for attaching each curved member to the side plate so as to be adjustable relative to the side plate in the circumferential direction of the cylinder. Provided is a card device characterized in that:

By separating the part of the curved member that meets the surface into multiple adjustable curved members, the flat bearing allows the flat to draw a trajectory on the main card cylinder against the card member covering with extremely high precision. In this way, the curved member is easily installed.

Preferably, for each curved member there are two adjustable mounted devices angularly spaced apart from the ends of the member.

Each mounting device has a supporting device attached to the side plate with an outer circumferential surface approximately concentric with the circumferential surface of the card cylinder, and an inner circumferential surface of the curved member and an outer circumferential surface of the supporting device. There are two types of devices: one for adjusting the gap provided between the two, and the other for attaching the curved member to the support device with the required spacing.

On both sides of the card device, the support devices may be continuous curved members attached to the side plates, corresponding to at least a sufficient degree of curvature of all the curved members. Alternatively, the support device may comprise one or more separate support blocks for each curved member.

A suitable adjustment device is a shim provided between the inner circumferential surface of the curved member and the outer circumferential surface of the support device. The use of shims provides a number of advantages, as detailed below. For example, the curved member can be reinstalled quickly and with high precision. Instead of a shim, the adjustment device may be a threaded adjustment device of any suitable type, such as a filbow structure.

Bearings with larger radii allow radially outward adjustment of the curved members providing the surfaces to widen the gap between opposing ends of adjacent members.

Such a gap can be tolerated to some extent in a flat bearing as long as it does not significantly affect the movement of the flat bearing. However, if the movement of the curved member toward the outside in the radial direction is coupled with a slight movement of the member in the circumferential direction, some parts of the curved member overlap, and other parts of the curved member overlap. This results in the formation of a completely large gap. This problem can be solved by suppressing the movement of the curved member. That is, at least one of the curved members at the center suppresses movement of the side plate in the circumferential direction. Furthermore, the movement of at least one of the end curved members is suppressed so that it moves relative to the side plate only in a direction parallel to a plane formed by the end face of one member facing the end face of the next adjacent member. Good too. like this.

By one, or preferably both, of the effects, the problems associated with the above-mentioned gaps are solved.

The above-mentioned features of the card device according to the present invention will be better understood based on the following drawings and examples.

Figures 1 to 6 show parts of a card device comprising a main cylinder (1) with a card member (2) on its outer surface. The cylinder (1) is hollow and supported on the parts by means of a conventional spider (3) and suitable bearings on both sides. A fixed side plate (4) is attached to the frame (5) of the card device. It should be noted that only one side is shown since the structure on each side of the card cylinder is all identical except for symmetry.

On each side of the card cylinder, a side plate (4) is welded to a curved support member (6). This support member (6) has a curved outer circumferential surface formed to have a common central axis with the outer circumferential surface of the card cylinder. 5 curved members (8
) to (12) are all supported by the support member (6).

(7) Each curved member (8) to (12) has an inner peripheral surface (1

The bearing for supporting the member forms a surface on the flat which is supported so as to move over the bend. In the illustrated embodiment, the flat bearing is a member of the spindle (16) supported on the end (17) of the flat (18).
) is rotatably attached to the roller (15). In another embodiment, it may be supported by an end member that can slide over the curved portion. The outer circumferential surface of the curved member is, of course, formed so as to match and support the dong-shaped support structure provided with the flat.

Each curved member is generally adjustable in the radial direction of the cylinder relative to the side plate (4). For this purpose, an adjustment device may be provided close to each end of each curved member.

This adjustment device consists of a shim (16) provided between the inner circumferential surface (13) of the curved member and the outer circumferential surface of the support member (6). Also, the bolt a is inserted through the hole in the support member (6).
7) to engage with the screw hole (17a) provided in the curved member. As will be described in detail later, by using shims (16) of appropriate thickness, the side panels can be
8) The bending member can be adjusted appropriately. By providing the shims in the appropriate locations, the bolts (1η) are tightened tightly in order to press the curved member against the support member (6). Each of the curved members (8) to (■2) is provided with a hole α9. ing. This hole (
Via 19), the pole (20) engages with the slot in the side plate (4). Thereby, the curved members (8) to 02
) can be attached to the side plate facing the axial direction of the cylinder.

The middle curved member (10) is provided with a groove (21) extending in the radial direction of the cylinder. The surface provided with the groove (2I) faces the side plate (4), and a dowel (221) attached to the side plate engages with the groove (2I). movement in the circumferential direction relative to the side plate is prevented.2
The curved members (8) and (12) are held immovably by stop plates (22 and 23) welded to the side plate (4). The contact surface (24) of the stop plate (22) is in contact with the contact surface of the curved member. These contact surfaces (2(a)(25)
) is arranged in a plane parallel to the end face (26) of the curved member (8), facing the end face of the adjacent curved member (9). Therefore, the curved member (8) is prevented from moving in a direction parallel to these planes. Similarly,
The opposing surface between the stop plate (23) and the curved member (12) is the end surface (29) of the member (12) that opposes the adjacent curved member circle.
It is in a plane parallel to .

The movement of the members (8), (10), and (+2) in the circumferential direction relative to the side plate (4) is suppressed by the above-mentioned suppressing device. The curved member (9) (I+) is not provided with such a restraining device.

However, the circumferential movement of these members (9) and (11) is limited by the adjacent curved members.

It is adjusted to move only within the width of the gap (30) provided between adjacent members. Thus, a support member such as a roller can move over the gap without noticeable effects.

The method of installing the curved member on the side plate (4) is shown in FIG.

In a normal card device, between the tip of the card member (2) of the card cylinder and the tip (31) of the cooperating card member provided on the flat, the flat extends over the entire curved part opposite the cylinder. It is necessary to provide gaps at equal intervals. That is, the bearing of each curved member has a surface (
The spacing (a) between l(1) and the tip of the protrusion (2) of the card cylinder should be as uniform as possible around the bend. The curved member can be mounted without a flat on the card device using the mounting fittings (32), which are wide enough to span the width of the cylinder. , s - (33).Hard pad (34) Cover (33) O Extends downward on both sides and comes into contact with the tip of the card member (2).Bar (33) A micrometer screw (35) with a tip (support) is provided on both sides of the screw.

At the tip (3G), the bearing of the curved member α0) is brought into contact with the surface 04). Attachment of the main body of each curved member is done sequentially. The pad (34) is attached to a bar (3) extending in the direction of the central axis of the cylinder and a micrometer screw (
35), a mounting tool is placed so that it is supported on the tip of the cylinder wire. A micrometer screw G5) is placed at the appropriate end of each curved member on each side of the card device so that it lies flush with the bolt (1'7). Next, Sim (+6)
is selected and inserted between the curved member and the support member (6). The thickness of this shim 06) must be large enough to allow contact between the tip of the screw (35) and the bearing surface 04). After inserting the selected shim (+6), bolt 07) is tightened. Next, the other end of the curved member on the opposite side of the machine is moved, a similar shim is selected, and the bolt αη is tightened. This step is also done for all other curved members. At the end of this stage, the bearings of each curved member are positioned such that each end of the surface is exactly at the same distance (a) from the card member of the cylinder. In such a body arrangement, the bearing can wear the surface in order to obtain absolute concentricity between the surface and the main cylinder. This concentric state is not changed thereafter except at the stage of replacing the shims.

If you want to create a gap between the card member on the flat and the cylinder after the main body is placed,
(20) It is easy to loosen (1η), insert an additional shim of the desired thickness, and retighten the bolt. Using a shim of a predetermined thickness in this way,
Eliminates the need for luggage and other equipment for new assembly. To reduce the gap, remove the shims if necessary9, by a predetermined amount, than the first one.
This can be done by reinserting a thin shim.

As previously mentioned, it is common practice to equalize the gap between the card member on the flat and the card cylinder over the bend where the flat opposes the cylinder. However, other arrangements require a gradually increasing gap around the bend. This can be easily done by simply selecting a shim in which the thickness of the curved member and support member (6) is gradually increased.

However, it is desirable to use shims of the same thickness at each adjacent end of each pair of curved members so that the bearings do not create steps in the surface.

The embodiment shown in FIGS. 4 and 5 includes a card member (1
02) is shown with a main card cylinder (101).

The card cylinder is supported on the frame by a bearing member. From this frame, side plates (103) extend to both ends of the cylinder. Each side plate (103) supports a curved section made up of a plurality of curved members (108). All of the curved members (108) are similar in construction and their components. Each curved member has an outer circumferential surface that supports the flat end during movement around the card cylinder.

Each curved member (ios) has two
Support blocks (110) (111) are provided.

Each support block can be adjusted in the radial direction of the side plate, and can be attached freely using bolts (112X113X114X115). The bolts are inserted into holes in this block, making the necessary adjustments and engaging slots in the side plates. (116) (117) (116) (117)
) is further provided. The curved member (ios) is attached to the side plate by two poles (118x119).

These two poles (118) and (119) are inserted into holes provided in the curved member and slots in the side plate (103).

As in the previous embodiment, the curved member is arranged to form a generally continuous trajectory around the curved portion of the card device. This trajectory has approximately the same central axis as the main card cylinder.

To position each curved member, the following steps are performed.

The support block and the bending member are loosely fixed by adjustment bolts (116) and (117). Next, install the board (1
20), the bearing of the curved member is fixed to the surface by Pol 1-(121). This is done by laying down the leading end of the card member of the main cylinder, as shown in FIG.

The installation is held firmly against the card member by the member.
Bolts (118) (119) are tightened to secure curved member (108) in place. Support block (11
0) (111) is pulled out from the inner peripheral surface of the curved member by tightening the bolts (116) and (117). Therefore, the support blocks are pol) (112) to (
115), it is firmly fixed to the side plate. During installation, the plate (120) and bolt (121) are held at the same level as the tip of the card member of the main cylinder.

Normally, the surface of the bearing must be slightly above the tip of the bearing surface of the main cylinder. In order to make this (15), Pol) (118) (119) is loosened. That is, the bolts (118X119) are removed so that the curved member (108) moves radially outward. A shim (122) equal to the width of the required gap is inserted between each support block (110) (111) and the inner circumferential surface of the curved member.
) to securely secure the curved member to the curved surface.

As in the first illustrated embodiment, adjacent curved members (108
) It is preferable that some gap be provided between the ends of the two ends. However, this gap may be minimized by controlling the members during installation so that they do not overlap circumferentially.

Interference with the smooth running of the seven rats over the gap can be reduced by forming the gap between adjacent curved members in an oblique direction, as shown in FIG. If it is desired to completely eliminate the gap in the surface of the bearing, it is advisable to attach a uniform band of uniform thickness to the surface of all the bearings of the curved member after installation of the curved member. The curved portion spans the gap, where its outer circumferential surface becomes the outer (16) circumferential surface of the flat end.

If a shim is inserted between the curved member and the support device to form a continuous surface, the bearing will form a continuous surface due to the fact that the surface is exactly concentric with the covering of the tip of the card member in the main cylinder. Change the relationship between the main cylinder. By changing the shims, movement toward the radial center or circumference of the member eliminates the concentric relationship from the above relationship.

Therefore, at the end of each curved member, by leaving a space between the bearing surface and the covering part, the bearing can maintain the curved shape of the surface, the bearing can maintain the maximum value at the center of the surface, and the bearing can maintain the maximum value at the edge of the surface. change to the minimum value at . However, the angle corresponding to the curved portion of each curved member at the center is 70° or less, and the bearing has a percentage difference between the radius of the surface and the radius of the covering portion at the tip of the card member of 0.05°. % or less, the difference in the gap becomes so small that it can be ignored. this is,
This is applied when it is desired to operate the card device by setting the distance between the card member on the flat and the card member on the main cylinder to a minimum value such as 3.63 x 10-'cIrL (1/7000 inch) or less.

The angle corresponding to the arc of the curved member is, of course, not limited to a maximum value of 70°. Larger angles are also permissible if accurate mounting is made.

The number of curved members can be increased compared to the previous embodiment. Other methods of providing the necessary support for the curved member and adjusting the support relative to the curved member may also be considered. The cooperation between the flat and the curved member was a phenomenon that occurred with conventional devices in which the flat and the curved bearing moved in a plane.
