Abstract

A portable dispenser(10) for welding electrode rods includes a tubular casing(12) with a top end cap having an axial opening allowing dispensing of a single rod on manual actuation of a reciprocable pusher engaging the rod lower end. A friction grip disc (32) normally closes the cap opening but permits passage of a rod and grips a partly-dispersed rod to prevent it falling back into the casing. The rods are held in a top compartment of the casing defined at the lower end by a dise through which the pusher extends The disc is movable by the pusher engaging a cam so that it rises and then falls to provide a mechanical shock preventing the electrodes jamming.

The present invention relates to rod-shaped articles, preferably to welding electrode distribution.

In the production and sale of the welding electrode, care should be taken to even the distribution of flux to the surface of the electrode, and care should be taken in the packaging of the electrode to minimize damage. The uniform distribution of flux is important for the consistent operation of the welding process. If the flux coat is damaged in any way, the quality of the weld surface is impaired. Much attention has been paid to providing a high quality product in the workplace, but when the workplace is reached, the electrodes are deformed before use.

In a construction workshop, welders usually carry a large number of electrodes to a workplace that may be remote to save time.

Limited time and fail-safe areas are provided because of the need for welders to survey the frames, climb ladders and steel structures, and to be stuck in inaccessible positions.

The welder usually puts a large number of electrodes in a pocket and the electrodes can easily be dropped by the welder's movement or bowing, which causes damage to the electrodes. Moreover, this is another possibility of continuous damage if the electrode is dropped at a distance from the workplace. Not only is electrode loss an economic loss, but a loss of working time also results. This is because the welder must replenish the electrode supply.

Another problem is that damage to the flux surface, which may occur in the rapid absorption of moisture in the atmosphere, results in a significant decrease in the integrity of the weldment.

If such electrodes are used for welding, cracks and bonds in the weld will occur, which will often cost cutting and complete re-welding of the welded joint.

For this reason, the electrodes were heated to remove the moisture, grease or other harmful substances from the weld. However, the electrodes used were cooled enough for the welder to handle, and they then wiped away deformations due to atmospheric moisture and bad weather conditions such as rain or snow at the construction site.

The present invention is to provide a portable welding electrode distributor which overcomes the conventional technical problems.

Multiple welding electrodes were placed in the vessel until one was desired by the welder, at which time the electrodes emerge quickly and safely from the vessel. In this way, the electrodes are protected from potential damage until they are actually required to be used, and potential moisture damage is minimized without taking into account unexpected movements and secondary risks.

The dispenser is portable, reusable and attaches to the welder's waistbelt. The disassembly operation is simple, effective with one hand, and uniquely safe in many incredible workplace locations.

The dispenser dispenses one at a time from the top of which the casing is long and coaxially from top to bottom in the tubular cavity and for receiving a number of long electrodes or for placing another rod-shaped item therein. The upper end closure is normally installed in the case at the end of the first cavity, and the cavity separating disc is arranged inside the space from the top closure to the bottom end of the first rod receiving pupil to separate the first cavity from the J cavity. The top closure is mounted on the case so as to accommodate a number of rods in the first cavity one at a time and selectively separated from it.

The top seal lies coaxially with respect to the primary pupil and is in contact with each other and has a distance that allows the distribution of only one rod from the primary cavity at a time. The top closure includes a path for guiding dispensing through the coaxial opening through the electrode as it is dispensed.

Disks of oil-soluble elastic materials with transverse incisions or other suitable loosening friction gripping means may normally pass through the rod under the nutrition of force acting axially on the electrodes to seal the opening to prevent the incorporation of moisture into the atmosphere. And by communicating with a stationary closure that secures the stationary electrode partially discharged to the dispenser by the application of a force acting laterally, the partially discharged electrode does not return to its cavity under gravity and The partially discharged electrode can be manually fixed to yield a residual passage.

The seal lies on the axis within the J pupil to reciprocate the axis of the cavity, and the seal is ejected in the same way through the cavity of the upper closure in an upward axial motion through the cavity separation opening towards the upper closure. It is received through an opening in the pupil separation disc to occlude at the bottom of one electrode. The manual drive method was connected to the seal in order to drive the axial reciprocation of the seal for ejection of the electrode from the first cavity and was installed outside the case.

The lower end cap was installed opposite the upper end closure, so in the second pupil lower case.

The plurality of welding electrodes are discharged from the distributor one at a time, the top closure is opened again, and a new plurality of electrodes is placed in the first cavity.

The welding electrode distributor 10 is actually a hard tube-shaped case, referring to the illustration, the bundle 14 is near the top of the case 12 and the closure 16 is at the top and the bottom cap 18. And the driving knob 20 or the like.

The various components of the dispenser 10, with the exception of seals and connecting rods, are usually molded by friction mold discs and grating discs made of synthetic materials, rods and grating discs made of metal, and the friction gratings are made of rubber or It is made of flexible, flexible material that is convenient to the outside. The hook 14 is provided with a vertical slot through which the belt 24 or the like is fitted to suspend the distributor 10 at the waist of the welder. The hook 14 must have a space for the distributor 10 from the welder's body to hang vertically unobstructed from the butt of the welder. The circular openings 26 were hooked through hooks to nails and the like when not using the dispenser 10 or hanging from the rope in a convenient location in the workplace.

The tubular case 12 is hollow and extends from its end to the end so that the cavity 30 is long in the shape of a tube and the case 12 has a limited axial motion therein as described below. The disk 32 and the lower pupil 34 mounted in the pupil 30 were separated.

Although the tubular case 12 and the tubular cavity 30 are circular cross sections, the present invention also encloses other cross-sections of a free shape, such as eight, six or four. The tubular shape used in it will include various shapes.

The disc-shaped gap bundle 36 installs an axial opening 38 and a rod mating surface 40 that is recessed downward.

The upper closure bundle 16 normally closes the upper electrode receiving cavity 32 surrounding the plurality of electrodes therein, but the upper closure bundle is screwed to the case 12 with threads 42.

The upper closure bundle 16 has a tip of the opening 46 and the outer surface 46 inclined, and the upper closure bundle 16 is assembled to the case 12, paying attention to the axis of the cavity 30. Lies in the axial direction. The outer ramp surface 44 has a number of upright ribs 47 that help and strengthen the quick separation and engagement.

Kidney tubs are threaded in the upper closed bundles (16) and then screwed on the kidney tubules with the shape of a similar thread to the thread (42). This elongate tubing is used when the length of the electrode housing cavity 32 is exceeded. However, usually the tubular case 12 has a distance for distributing an electrode having the same length as the electrode housing cavity 32.

Under the opening 46 a disk 48 made of rubber or a useful material is cut in the center with a cross cut 50.

The rubber disc 48 has a looped shape of the opening 46 between the barrier 52 and the lower ring support bundle 54, and the rotating portion protrudes from the conical bundle 56 inside the closure 16. It is. Conical bundle 56 acts like a length or current transformer to the electrodes distributed from cavity 32 and acts as described below.

The cross cut 50 in the rubber disk 48 is engaged with the axial opening 46, and the downward opening 57 of the conical bundle 56 is installed in the upper opening 16 axial opening so that only one at a time Electrode distribution is allowed and electrodes of various diameters may also be placed in the distributor 10.

The ring bundle 58 is fully engaged with the closure 16 and is free to rotate between the thread 42 and the protruding bundle 60. Ring bundle 58 prevents accidental loss of closure 16 when dispenser 10 is opened with multiple electrodes in pupil 32.

The case 12 has an elongated groove 62 on its outer surface that extends parallel to the axis of the length of the case, starting at the lower end cap 18 and slightly away from the upper end closure 16. The house 62 includes a hollow portion 64 having an upper opening that extends in length, and has a slot-shaped opening 68 extending in a direction opposite to the boat at one side of the house 62 toward the upper closure 16. Have The house 62 includes a closing cover 70 extending on the way covering the upper opening 66 when assembled.

The elongate house 62 consists of a connecting rod 72 connected between the seal 74 lying on the axis of the cavity 30 and the actuating handle 20, the seal 74 being subjected to the axial reciprocating motion described below. Can withstand The seal 74 has a concave surface at its end to engage the generally convex lower end of the welding electrode.

The connecting rod 72 has a portion 76 perpendicular to the shaft and a portion 76 protruding from the slot 68 and perpendicular to the 75 and the slot 68 as described below. It is of appropriate length to facilitate movement of the rod portion 76 during operation.

The pupil 34, which is installed without slipping by the chain receiving groove 78 and does not rotate, is located at the end of the hollow tubular bundle 80, and is closed by the end wall 81 to the room with the disc grid 36. have.

The tubular bundle 80 has a long slot 84 in the wall of the case 12 in which a portion 86 in the direction of entering the interior of the connecting rod 72 connected to the lower end of the seal 74 is connected inside the house 62. ) And long slots 82 formed on their sidewalls and move in the axial direction of the case 12 during operation of the dispenser 10.

The end wall 81 has the same axial opening 88 of the opening 38 in the partition disk 36 through which the sealing 74 protrusion passes. The other opening 90 was provided in the wall 81 to drive small flux particles or other small material out of the dispenser 10 so as not to interfere with proper operation.

The protrusion from the end wall 81 of the tubular bundle 80 hollowed toward the partition disk 36 is pivotal, and the stationary bundle 92 has a space parallel to the vertical support bundle 98. 94 and perforated opening 96.

The pivot pin 100 is fitted with the opening 96 and the cam element 103 is loosely fitted in the opening 102 for the pivoting movement of the cam element 104 relative to the pivot pin 100.

The pivot mount 92 is positioned on the lattice disk 36 to engage one side of the disk 36 with the inner end of the support bundle 98 and the wall 94 and the lattice disk is an annular mound in the cavity 30 ( Engage with pivot mount (92) toward 105) to move out.

The cam element 104 has a connecting rod bite cam follower portion 106 that engages with the crank-shaped cam portion 108 of the connecting rod 72 and protrudes through the opening 84 of the case 12. As will be described, it occurs as occurring toward the ring-shaped mound 105, creating a pair of spaces in the cam arm 110 for equilibrium coupling with the partition disk 36. The entire leg 112 extends from the arm 110 which normally contacts the end wall 81.

This leg bundle 112 moves as the cam element 104 bounces back into place at the remaining position during ejection of the rod 114 from the dispenser 10 as described below.

The semi-circular cross-sectional protrusion 110 is an empty tube towards the partition disk 36 between the arms 10 of the cam element 104 while in the partially enclosing path of the rod 74 on its opposite side from the pivot. It will extend from the end wall 81 of the bundle 80 and be completely installed. This protrusion guides the rod 74 and blocks the narrow diameter protrusion rod through the opening 38 by stopping the protrusion device by the non-axial alignment of the rod 74.

The lower end cap 18 covers the lower end of the case 12 and fixes the tubular bundle 80 at the position of the cavity 30.

The lower end cam 18 rests on the case 12 with the interfering bite of the rib 116 of the hat on the rib 118 on the inner wall of the case 12.

The lower end cap 18 lies straight on the inner axis of the frustocone 120 acting on the lower stop bundle by the interaction of the seal 74 and becomes apparent from the description of the operation of the dispenser 10 as described below.

The bottom cap 18 also sends fine material out of the cavity 32 through the opening 38 in the disk 36 and out of the dispenser 10 to the opening 90 in the wall 81. .

During operation, a plurality of welding electrodes 114 or other rod-shaped elements open the top closure 16 and fill the distributor 10 through the opening from above. The cavities 32 generally have a length equal to the length of the rod.

The weight of the electrode and the weight of the moving septum disk 36 are equally taken up in the position where it engages with the pivot mount 92.

When the top closure 16 is placed back in the case 12, the electrodes are effectively sealed into the pupil 32 and prevent the entry of air or other moisture into the cavity 32 and the lowering of the flux from the influence of moisture Evade.

The electrode 114 is damaged by the hard case 12, which prevents the electrode from erroneously coming out of the lower or rotor protection, and overcomes the above difficulties and safety barrier areas of the current welding run. The welder places the dispenser 10 from the container supply and attaches the dispenser 10 about his waist using a belt 24 and performs it in the workshop.

When the electrode 114 requires separation from the cavity 32, it is realized by the operation of the drive handle 20. In the remaining position (see also FIG. 3), the sealing 74 has a lower end of the electrode 114 in the cavity 32. It lies on the axial opening 38 of the grating disk 36, the protrusion 106 of the cam element 104 contacts and engages the crank 108 of the connecting rod 72, and the rod projection 76 is a slot 68. In the space at the bottom of the

The initial movement of the drive handle 20 is connected internally via the rod 72 such that the rod projection 76 moves downward toward the lower end of the slot 68, so that the seal 74 opens toward the stop bundle 120. Move out of (38).

During this movement (see FIG. 4), the crank 108 engages the protrusion 106, the cam element 104 pivots pivotally of the pivot pin 100, the arm 110 moves, and the ring shape The disk 36 is placed back upwards to the mound 105 of, thereby also slightly pulling the electrode into the cavity 32. The cam bundle 104 continues the pivot movement of the cam bundle 104 and the movement of the disk 36 until the crank 108 permits sufficient passage of the protrusion 160.

Downward movement continues until the seal 74 engages the stop bundle 120 (see FIG. 5). In the meantime, the relaxation of the pivot force of the cam 104 occurs as a result of the weight of the electrode on the moving bulkhead disk 36 which causes the disk 36 to quickly return to its own weight, which is applied to the pivot support 92. Cam 104 is returned to the occlusal home position and the cam 104 is returned to its remaining position.

In this way, stagnation of the disk 36 in engagement with the tablet pivot support 92 transmits a mechanical shock, swings the electrode and prevents mechanical stop due to the model. This movement is brought into alignment with the shaft opening 38 where the surface 40 of the disk 36 engages in a concave downward configuration and one electrode engages the seal 74 to prepare for dispensing movement.

It is a feature of the present invention that the oscillation occurs by the engagement of the cam element 104 and the disk 36 and later relaxes after the electrode is ejected from the distributor and placed in the correct position for mating by the seal 74. .

If this machine is omitted, however, the electric clear end has been reached, and when the seal 74 is engaged with the stop bundle 120, the handle 20 is raised and during this operation, the seal 74 is in FIG. It first passes through a position as shown in, and then through the opening 38 to engage the lower end of the electrode 114, the protrusion of the seal 74 is brought into the position shown in FIG. 3.

As the seal 74 passes from the position shown in FIG. 4 to the position shown in FIG. 3, the cam bundle 104 pivots into the spring 112 movement as the crank 108 shows in FIG. 7. It pivots around and slides to the bottom of the protrusion 106 and engages. As the crank 108 passes over the protrusion 106, the cam 104 returns to the remaining position as shown in FIG. 3 by the elastic movement of the spring 112.

The continuous movement of the seal 74 is due to the start of ejection with the electrode 114 bite, and the conical insert 56 is axially aligned with the cross incision 50 in the rubber disk 48.

The occlusal electrode pushes through the cross-section 50 and then passes through the opening 46 (see FIG. 8). The size of the seal 74 and the lower portion of the opening 57 of the conical insert 56 is ejected by only one electrode 114 through the opening 46 and the cross cut 50 at any time. The dowel 48 prevents warping during this operation by the sandwich position described below.

The axial movement of the seal 74 continues until the connecting piece 86 engages the upper end of the slot 82 and where the rod 74 and the rod protrusion 76 are located is roughly shown in FIG. Reach together and thereby the electrode is partially ejected from the cavity 32. The drive handle 20 is now relaxed, and the seal 74 falls back to the remaining position as shown in FIG.

The seal 74 lasts in this position by contact bite of the crank 108 with the protrusion 106 and by bite bite of the arm 110 with the disk 36.

A portion of the electrode 114 is ejected by the movement of the seal 74 and when the electrode is relaxed by elastic friction gripping bite of the partial bundle of the cross cut 50 simultaneously with the electrode near the driving handle 20. Relaxation of the upward force prevents it from falling back into the dispenser 10.

This friction gripping bite holds the electrode partially ejected in place for the welder to hold the electrode, and draws the residue at the outlet in the same way to use the distributor 10. Once the electrode 114 pulls in the residue at the outlet and the elasticity of the bundle of cross incisions 50 reduces the cross incision 50 in its closed position.

By describing the disk 48 and cruciate 50 movements it is clear that it can perform the same function better than any other convenient instrument.

Thus, even though the welding electrode is sealed and stored in the container until use, the driving hand is simply used in one hand by the upward motion of the upward movement of 20 to eject safely from there and then enter the partially ejected electrode with one hand. Multiple electrodes can be used at one time and a new multiple electrode can be placed in the pupil 32.

A summary of this specification is a dispenser in which the present invention benefits from the convenience of using welding electrodes or other rigid rod-shaped articles. Modifications were possible only within the scope of the present invention.
