Description

The invention relates to a storage device for C cursors.

  As we know, with the sliders, we fill the rings with spinning and twisting rings. For this purpose, among other things, insertion instruments are used

  similar to pliers which have an emma-

  gasinée of sliders. From this reservation, we successively withdraw-

  the cursors one by one and we put them on the rings.

  For the storage of the cursors, use is made, among other things, of cursor supports which carry aligned cursors. Such a slider support can be designed, for example, in the form of a clamp formed of elastically flexible material, having an open longitudinal slot

  and now together elastically, by their outer side

laughing, the sliders aligned.

  The invention aims to store the cursors of a

simple and reliable way.

  According to the invention, this problem is solved by the fact that the storage device comprises an oscillating bottom which can be set in vibration, having a bottom opening and inclined towards the bottom opening, receiving the sliders flat and conveying them in the direction of the bottom opening as a result of the vibrations and under the bottom opening of which is a needle whose point is turned upward and which continues through

  a profiled mandrel gathering the sliders.

  Since the sliders have a C-shape to which the profile of the mandrel can be adapted, the profiled mandrel bringing together the sliders finally performs an ordering of the sliders that are threaded, their feet being

arranged in a row.

  Sliders dispersed on the oscillating bottom are placed flat, move towards the bottom opening, arrive successively on the tip of the needle and

there on the chuck.

  Advantageously, the profiled mandrel is inter-

  changeable, with or without the needle. As a result, the storage device becomes universally usable since there are C cursors of different dimensions and that for

  each dimension requires a special mandrel.

  According to another development of the invention, it is provided that the mandrel with the sliders inserted fits into the slider magazine of an instrument for inserting

  sliders or itself forms such a slider store.

  As soon as a profiled mandrel is fitted with sliders, it is replaced by an empty mandrel. You can either insert the filled mandrel, as a slider magazine, into a slider insertion instrument, or push it into the slider insertion instrument magazine or slide it on the magazine mandrel. the cursors

  strung in an orderly fashion and thus stored.

  According to another development of the invention, it

  it is expected that the sliders assembled on the chuck pro-

  spun, after being surrounded by a clamp or a yoke leaving the feet free, can be removed from the mandrel

in packets down.

  The clamp is formed, for example, of synthetic material

  elastically flexible tick. Its inner surface is adapted to the shape of the sliders so that the aligned sliders are surrounded by the clamp on a large surface. The open longitudinal slot is advantageously at least wide enough for the cursor feet to be free. You can slide the clamp sideways over the

row of sliders in question.

  On the slider insertion instrument, for example, the aligned sliders surrounded by the clamp are placed on a magazine mandrel, after which the clamp can be removed from the side, exactly as previously adapted.

  on the chuck of the storage device.

  According to another development of the invention, the oscillating bottom has lateral limitations directed towards

  the edge of the bottom opening. Such lateral limitations

  rales have the role of driving towards the bottom opening the sliders placed flat, sliding along the bottom

  oscillating as a result of oscillations.

  In the simplest case, we can disperse my-

  nueurs the sliders on the oscillating bottom. However, since they easily form chains which

  should as far as possible already be separated before

  dye the oscillating bottom, it is provided, according to another development of the invention, that above the oscillating bottom is arranged a filling hopper narrowed towards the

  low slit, which can be vibrated.

  The chains already formed separate in particular-

  if the filling hopper has at its end

  lower half of the narrowing in the form of interstices remaining free between bars of preferably circular section, as provided for in another development of the invention. In general, these are not chains but cursors already released again from the chains which pass

  through the spacings between the bars.

  Since both the oscillating bottom and the filling hopper must oscillate, it is provided according to another development of the invention that the oscillating bottom is mechanically connected to the filling hopper and that both are connected jointly to a device of

vibration or percussion.

  During storage, it is inevitable that accumulations or knotting will form from time to time.

  sliders that then slow down or even prevent the em-

  shopping. So that such an accumulation of sliders, which is formed in particular at the bottom opening of the oscillating bottom, can be easily eliminated, it is provided, according to another development of the invention, that

  the oscillating bottom is articulated and raised

  ble to an envelope carrying the needle and the mandrel. After raising the oscillating bottom, the needle is then released and most often, the disturbance is already eliminated by

the only lifting of the oscillating bottom.

  According to another development of the invention, it is provided that at the place where the mandrel is connected to the needle, there is a longitudinal fin guiding the feet of the sliders. The longitudinal fin forces the sliders to

  arrange their feet in rows. This is particularly successful-

  lie well if the fin has a cutting edge directed towards the

  high. The cutting edge can also be laid down

  radially outward. Whether it is necessary or not depends primarily on the size and shape of the sliders. The oscillations of the vibration or percussion device are also transmitted to the envelope of the storage device and therefore to the needle and the mandrel. As a result, the sliders dance on the upper edge of the longitudinal fin until the position of their feet

  allows to slide further over the longitu- fin

  dinal. This is accelerated by the fact that, according to another development of the invention, at the height of the upper edge of the longitudinal fin is arranged a movable brush

  mechanically, which can be brought into contact with the cur-

sisters who slide down.

  Since this brush is advantageously mechanically driven, it is advantageous for the brush to be part of a brush disc rotating transversely to the sliding direction of the sliders and to have bristles directed radially. In the simplest case, the brush disc only needs to have one tuft of bristles. By the brush, the sliders which slide towards the

  bottom are moved transversely to the direction of sliding

  so their feet can orient themselves more

  quickly to the upper edge of the longitudinal fin.

  Since a percussion device is also

  particularly effective, another development of the invention

  tion provides that the percussion device has an oscillating lever, one end of which is designed as a striker which can abut against the oscillating bottom and

  the other end of which can be moved by an eccentric

  or a motor driven cam lever.

  According to another development of the invention, it is provided that at least one narrowing in the form of a slot, at the lower end of the filling hopper, is adjustable. This possibility of adjusting the shrinkage has

  in particular for the purpose of letting forged chains

  sliders and who do not want to separate, so that they collide as a whole the oscillating bottom and thus, as much as possible, separate all the same. The slit-shaped narrowing can be formed by an adjustable wall of the filling hopper. This wall can, for example, be arranged above the bars of circular section forming the lower closure of the filling hopper, so that the chains which do not

  not separate slide forward over the ends

  half of the bars and can fall from there on the oscillating bottom.

  Above the filling hopper is

  carefully arranged a chute feeding the hopper and

  intended to receive an unordered quantity of cursors.

  This chute is advantageously inclined towards the filling hopper and this inclination is advantageously adjustable. Since the chute also participates in the vibrations, its inclination can be adjusted in such a way

  that, from the unordered quantity, it does not continually-

  neither too much nor too few sliders in the hopper

pleating located below.

  Since the sliders do not fall evenly

  slightly but irregularly from the filling hopper

  on the oscillating bottom, accumulations can occur

  at the openings of the oscillating bottom as a result of a temporary accumulation of sliders. To avoid this, according to another development of the invention, it is

  provided that the oscillating bottom presents, at a distance from the

  bottom edge, at least one overflow opening. Excess sliders that move down fall at

  through the bottom opening and can no longer then

  tribute to phenomena of accumulation.

  Advantageously, the mandrel which brings together the sliders has an end portion inclined relative to

  horizontally. This terminal part is advantageously

  handy, so you can easily

  carry out all operations for removal and purchase

minus stored cursors.

  According to another development of the invention, for the elimination of the wedging of the cursors is provided a detachment lever which can be actuated, and which can be moved along the needle in the direction of the point. This detachment lever can be actuated mechanically and automatically from time to time, but it is also possible, depending on the case, to actuate it manually so that it can lift the sliders which accumulate or do not continue their movement, or still lift them beyond

from the tip of the needle.

  The casing of the storage device advantageously has below the needle, possibly below the mandrel, a collecting bottom for all

  sliders that cannot be threaded. The bottom collect-

  teur is advantageously arranged in an inclined manner by

  compared to the horizontal and has a collecting drawer.

  The contents of the collecting drawer can be brought back, conti-

  nuly or from time to time, at the filling hopper

or at the chute.

  So that we can always observe whether the storage

  sinage takes place normally and therefore at the same time, no cursor is lost by projection outside, it can be provided that the envelope surrounding the needle and only an upper part of the mandrel is covered forward

  by a removable window. Once you have removed or re-

  raised the window, the hands are also accessible from the front and we can then eliminate accumulations by

direct intervention from the front.

  Advantageously, the same oscillating bottom has

  several bottom openings and under each of these openings

  tures bottom is arranged a needle continuing by a profiled mandrel, intended to gather the cursors. Needles placed side by side can, for example, in this case, cooperate two by two with a single rotating brush disc. The vibration or percussion device has not

  need to be provided only once, likewise the hopper

  pleating, the chute and the collecting drawer.

  An exemplary embodiment of the invention is shown

  felt on the drawings. About this example of execution,

  the invention will be explained and described even more precisely

frankly.

  storage tif; Figure 2 is a partial elevational view, from the front, of the storage device shown in Figure 1;

  Figure 3 shows details of the emma-

  gasing according to Figures 1 and 2, in front elevation; Figure 4 shows part of the device of Figure 1 in longitudinal section; Figure 5 is a partial view from above of the storage device of Figure 1; Figure 6 shows a finished slider magazine; FIG. 7 shows sliders hooked together like a chain, and

  Figures 8 and 9 show details of the arrangement.

tif of figure 1.

  In FIG. 1, the storage device is generally designated by 1. It has an envelope

  2 provided with a collecting base 3 inclined with respect to the horizontal

  zontal, for all sliders that cannot be threaded. The collecting base 3 ends below two mandrels 4 and 5 gathering the sliders, above a

collector drawer 6.

  As shown in particular in FIG. 2, an oscillating bottom 7 is connected to the casing 2 in an articulated manner and

  liftable, by means of two articulations of rotation 8, 9.

  The rotary joints 8 and 9 are located in the respective side walls 10 and 11 which carry the bottom

oscillating 7.

  According to Figure 4, the oscillating bottom 7 is tilted forward and rests at the rear on a stop 12 connected to

envelope 2.

  In particular, FIG. 2 shows that the oscillating bottom 7 has two openings 13 and 14. The bottom openings 13 and 14 are large enough for sliders placed flat, for example the slider 15

  in Figure 4, can pass through.

  Under each bottom opening 13, 14 is disposed a respective needle 22, 23, the point of which is turned upwards and which continues through the respective mandrel already mentioned 4, 5, bringing together the sliders, for example

the cursor 21 in FIG. 4.

  Figure 4 shows that the mandrels 4 and 5 have a terminal portion inclined relative to the horizontal, which is directed in a straight line and has, in practice, a length of about ten centimeters. The

  end part of the mandrel 4 has, for example, already assembled

  wheat a slider pack 24 which can be withdrawn from the mandrel down in the direction of the arrow 25, once it has been surrounded by a clamp 29 which leaves the feet of the sliders free, for example the feet 26, 27 of the cursor at C 28 in FIG. 6. Arrows 30, 31 indicate that the clamp 29 can be slid sideways over the pack of cursors 24. It then surrounds the pack of cursors as the

  shows figure 6. The clamp 29 is formed of syn-

  Elastically deformable aesthetic.

  At the point where the mandrel connects to the needle is provided a longitudinal fin guiding the feet of the sliders. According to FIG. 8, the mandrel 4 has, by

  example, the longitudinal fin 32 and the mandrel 5 the fin-

  longitudinal 33. The longitudinal fin 32 has fixing holes 34, 35, the longitudinal fin 33, fixing holes 36, 37. The longitudinal fin 32

  has a cutting edge 38 directed upwards, the fin lon-

  gitudinal 33 a cutting edge 39 directed upwards.

  While the cutting edge 38 is directed horizontal-

  the cutting edge 39 forms a variant since it

  is arranged descending outward.

  The combinations of a mandrel and a needle can be easily changed. For this purpose, use is made, on the one hand, of the longitudinal fins 32, 33 already mentioned and, on the other hand, another fin 40, 41, which is perforated and is located at the lower end of the respective mandrel 4, 5. In the installed state, the fins and 41 are turned upwards as shown, for example, in Figure 4. To remove the mandrels 4 and 5 with the needles attached to them, simply unscrew

  knurled screws 42 similar to each other which are visi-

  bles, for example, in Figures 1 and 2. Then we can remove the longitudinal fins 32 and 33 of the supports 43 and 44 and lift the fins 40 and 41 relative to the crosspieces 45, 46 connected to the casing 2. Then , the mandrels 4, 5 with the needles attached thereto

  can be removed from the front and bottom. The mounting is

performs in reverse order.

  In particular, FIG. 2 shows that on the cross-member 45 is mounted a flap 47 and on the cross-member 46 a flap 48. The flaps 47, 48 are stressed so that they come to be applied to the respective mandrels 4, 5. The stress is ensured by respective coiling springs 49, 50. The flaps have the role of preventing the sliders from sliding from the mandrels. However, as soon as starting from the position shown in FIG. 4, the clamp 29 has been slid over the pack of cursors 24, the cursors now stored can be removed, after lifting / for example from the flap 47, in the direction of the

arrow 25.

  On the two mandrels 4 and 5 are still visible respective grooves 51 and 52 which are simply used for better adaptation of the clamp 29. Since the feet of the sliders are located to the left and to the right of the respective groove 51, 52, a longitudinal edge of the clamp 29 is placed in the respective groove 51, 52 and only then does the actual adaptation of the clamp begin. The longitudinal edge of the clamp slides again out of the corresponding groove, so that finally,

  the slider feet are clear, as shown in the figure

  re 6. From FIGS. 1, 2 and 4, it can be seen that the oscillating bottom 7 has respective lateral limitations

  53, 54 and 55, 56 pointing towards the edges of the openings

  bottom res 13, 14. The lateral limitations are formed by corresponding V-notches of a plate 57 resting on the oscillating bottom 7. As shown in particular in FIG. 4, the storage device 1 has a percussion device designated as a whole by 58. The percussion device 58 is able to communicate to the oscillating bottom 7, from below, tremors which lead to the

  vibration of the oscillating bottom 7. Not only the bottom oscil-

  lant 7 but the entire envelope 2 are vibrated.

  A part of the percussion device 58 is formed by a gear motor 59 whose shaft 60 carries a cam lever 61. The cam lever 61 can act on an oscillating lever 62. One of the ends of the oscillating lever 62 constitutes a striker 63 which can strike from below against

  the oscillating bottom 7. The other end 64 of the lever oscil-

  lant can be moved by the eccentric or the cam lever 61 driven by the motor. At each turn, the cam lever 61 strikes once against the end 64 and at the same time the striker 63 strikes from below against the bottom

oscillating 7.

  The side walls 10, 11 of the oscillating bottom 7 carry the rear wall 65 and the side walls 66, 67 of a filling hopper 68. By an adjustable wall 69 is formed, at the lower end of the filling hopper 68, an adjustable narrowing 70 similar to a slit. In addition, the filling hopper 68 has at its lower end other narrowing in the form of spaces 80 to 87 remaining free between

  bars 71 to 79 (Figure 5). Since the bottom oscil-

  lant 7 is mechanically connected to the filling hopper 68, both participate jointly in the vibrations and jolts communicated by the percussion device 58. The wall 69 has at its lateral ends respective lugs 88, 89. A detachable screw 90 connects the tab 88 on the side wall 66, a detachable screw 91

  connects the tab 89 to the side wall 67 (Figure 2).

  A console 92 fixed to the casing 2 carries a chute 92 disposed above the hopper 68, feeding the latter and intended to receive an unordered quantity

  sliders. The chute 93 has an adjustable inclination

  ble relative to the filling hopper 68. The tilt is adjusted by pivoting the console 92. The position of the chute 92 is fixed by application

  elastic of the console 92 against the casing 2.

  In particular Figures 1 and 2 allow

  see that the oscillating bottom 7 has, at a distance from the

  bottom groove 13, an overflow opening 94 and at

  distance from the bottom opening 14, an overflow opening

dement 95.

  To eliminate possible wedges of the cursors on the needles or at the transition from the needles to

  mandrels, a detaching lever is attached to each needle

  respectively, 96, 97. According to FIG. 2, the two detachment levers 96 and 97 are arranged on a shaft 98 passing transversely through the casing 2 and which can be rotated manually by an angle of about using a lever 99. According to FIG. 1, the lever

  99 is applied in the rest position against a stop 100.

  If the lever 99 is raised in the direction of the arrow 101, the two detachment levers 96 and 97 pivot upwards in FIG. 4, from their rest position, for example to the position indicated in phantom, slide along the mandrels and finally needles and detach towards

  the top, beyond the point of the needles, all the cur-

  sisters who are above. To this end, it is ap-

  ability to first raise the oscil bottom manually

  lant 7 of approximately 90, against the force of a retaining spring

nude 102.

  According to FIG. 1, the envelope surrounding the needles 22, 23 and the upper parts of the mandrels 4, 5 is covered towards the front by a removable window 103. The window makes it possible to continuously observe all the movements which occur at l inside the storage device 1. In the present embodiment, the window 103 is hooked, by means of hooks 104, 105, by

  above the pins 106, 107 provided on the casing 2.

  As shown in particular in Figures 2, 3

  and 4, at the height of the upper edges of the long fins

  tudinal 32, 33 is arranged a brush 108 which can be moved mechanically, which can be brought into contact with the sliders sliding downwards, for example with the sliders 20, 21 according to FIG. 4. The brush 108 is part of a disc of brush 109 rotating transversely to the sliding direction of the sliders 20, 21 and has bristles directed radially. The brush disc 109 is placed at the end of a vertical shaft 110. The shaft 110 is mounted in a bearing 111. The bearing 111 is carried by

  a console 112. The console 112 is connected to the enclosure 2.

  At the lower end of the shaft 100 is a motor

113 driving the shaft.

  In FIG. 4, it is indicated that conductors

  20114, 115, 116 lead to a safety transformer 121.

  In the safety transformer, an alternating voltage of 220 V is transformed into a safety voltage of 6 V. Conductors 117 and 118 conducting only 6 V go from

  safety transformer 121 to motor 113. Conduc-

  similar teurs 119 and 120 range from the safety transformer

  121 to the gear motor 59. In the supply conductor

  tation 122, carrying 220 V, is inserted a switch 123. A chain 124 is attached a pencil 125 serving

  accessory. The pencil 125 is used to move occasionally-

  the sliders and remove stubborn buildup.

  At the start of storage, the chute 93 is filled with C-shaped sliders which easily form chains of

  cursors 126 according to FIG. 7. The storage device

  ge is formed and constructed in such a way that this chain formation is not harmful. After closing the switch, vibrations, and therefore the routing of the sliders or chains of sliders intervene. Isolated sliders or chains fall into the filling hopper 68, arrive on the bars 71 to 79 and pass through the spaces 80 to 87 between the bars, in the already unconnected state. Individual parts of the chain which do not separate any more arrive via the narrowing 70, sometimes in the form of a chain, on the oscillating bottom 7. Such smaller chains separate

  then again most often by shock on the bottom oscil-

  lant 7. Flat, the sliders then slide individually-

  ment, under the influence of tremors, along the bottom

  oscillating 7, towards the bottom openings 13 and 14.

  Only the cursors moving along the limitations la-

  53 to 56 can reach bottom openings 13 and 14. All other sliders, which otherwise would easily cause build-up, fall through the openings of

  overflow 94 and 95 on the collecting base 3 placed-oblique-

  ment, like, for example, the cursor 17 in FIG. 4. The rejected cursors, for example the cursor 18, arrive, in

  sliding along the collecting base, in the collecting drawer

  tor 6. From time to time, we remove the drawer 6 and we

empty in chute 93.

  Almost all the sliders that fall through the two bottom openings 13 and 14 arrive on the needles 22 and 23. They slide along the needles and are gripped and rotated, at the ends of the needles, by the rotating brush 108. Their feet are oriented to the left and to the right of the longitudinal fins 32, 33. As soon as this has happened, the sliders which are already on the chucks 4 and 5 continue to slide as indicated

Figure 4.

  The clamps 29 are adapted during the operation of the storage device 1. Consequently,

  it is not necessary to deactivate the device.

storage tif. -

  Through window 103, it can be observed whether pheno-

  accumulation leads are felt. To eliminate such accumulations, the lever 99 can be raised from time to time in the direction of the arrow 101. If this is done at

  not too long time intervals, accumulation phenomena

  Important mulation does not happen to begin with.

  With the stirring pencil 125, you can conveniently influence the distribution of the sliders in the hopper

  68 or route through the outlet openings

  border 94 and 95, on the oscillating bottom 7, chains

  possibly existing and which cannot be separated.

  In FIGS. 8 and 9, it is indicated how the brush 108 works. The brush disc 109 rotates in the direction of the arrow 127. According to FIG. 9, it precisely grasped a cursor 128 and made it rotate in such a way. so that its feet are oriented to the left and to the right of the longitudinal fin 32. On the other needle 23, a cursor 129 rests on the cutting edge 39 of the longitudinal fin 33 and cannot slide further on the needle nor on the mandrel 5 which follows. As soon as the brush 108 passes through this place, this cursor also is oriented so that its feet are located to the left

  and to the right of the longitudinal fin 33.

  In FIG. 8 is still indicated an accumula-

  sliders 130. This accumulation can be eliminated by pivoting the detachment levers upwards

96 and 97.
