Definitions
- the invention relates to a device for feeding assembly parts at least one upper or lower tool of an assembly machine for loading or Processing of the assembly parts, with the upper and lower tools are movable relative to each other between a working and a resting position, the assembly parts for each tool via a feed channel are fed by means of a feed tappet, and the feed ram is located on a ram (US-A-3 069 688).
- Such devices for feeding assembly parts are known per se. They are used especially in machines for riveting, snap fasteners or the like is used.
- a generic Device for feeding assembly parts in the WO 93/12680 (& DE-A-42 25 264) describe. Accordingly, a spring-loaded lever with a boom on one arranged on a stroke-controlled upper tool arranged guideway and is counteracted by the movement of the upper punch against the spring force pressed into a rear position. With this movement, a sled becomes moved to a retracted position, on which plungers are arranged. If the stroke-controlled upper punch returns to its upper position, the Lever pulled and moved to a forward position due to the spring load the carriage also in a forward position.
- the plungers then bounce on the assembly parts held ready in feed channels and guide them to the Upper and / or lower tool or the holding tools arranged thereon to.
- the feed rams are in a far behind the point of use current position. This results in the high Return speed of the lever a significant impact speed of the ram on the assembly parts to be fed. Because of this impact the parts are damaged in an undesirable manner and it becomes high Committee produces.
- the masses need to be in accordingly short distances to travel, so that a lot of energy is required for operation is. If you want, for example, by a corresponding lever arrangement if you shorten these distances, the insertion time is automatically reduced.
- the present invention is based on the object, the effect to improve a device for the supply of assembly parts of the generic type in that the structure is simplified, the maintenance, the susceptibility to wear and the adjustment or coordination requirements are reduced and the onset time varied by simple means is.
- the feed plunger can be moved back and forth in the plunger longitudinal direction by means of a push crank.
- the feed ram movement in primarily independent of the movement of the tools, so the possibility is improved to vary the movements. So the feed path be reduced by the arrangement of a corresponding push crank, so that the speed of impact of the feed plunger on the provided Item is smaller. Furthermore, do not need as many masses at high speeds to be moved so that the energy consumption is significantly reduced becomes. In addition, the maintenance and coordination efforts decreased.
- the ram can be moved back and forth by means of a centric push crank is.
- the central arrangement of the push crank avoids the use of the more susceptible and linkage to be adjusted.
- the centric is advantageously used Slider crank below the pusher carriage between the front and rear Reversal points arranged.
- This is particularly advantageous Connection between the push crank and the ram from one to the Thrust crank arranged roller, which is arranged in a on the ram Leading curve expires, the width of the orbit of the roller corresponds.
- Such cranks are called cross-slide cranks, which in the case of the present invention with a curve in the form of a locking gear be combined.
- the guide curve advantageously has a radius.
- the radius of the guide curve is such that the roller is in one of the reversing positions without transmission of thrust runs over an angle f. This measure makes it possible to take a break of the ram in one of the two reversing positions.
- the center point of the radius of the guide curve lies between the Guide curve and the plunger, so that there is a rest in the rear reverse position results.
- the radius length is advantageously adjustable. For example this can be achieved by adjustable guideway backdrops.
- the sliding crank is a disc, which according to a proposal of the invention in a gear chain of a drive wheel of the drive Attaching machine is driven.
- the ram is a sled, which in advantageously carries two plungers.
- the tappets on the tappet are advantageously in Guides used. This makes it easy to adjust and replace guaranteed.
- the plunger in the guides are arranged by means of a locking connection. Except of the easy interchangeability and adjustability can be achieved through the snap connection the plunger can be pushed into the guide when it is on a Obstacle hits. The destruction of machine parts due to defective assembly parts is avoided by this detent.
- the locking connection is advantageous formed by a spring-loaded locking cam.
- the locking cam snaps according to a proposal of the invention in a locking groove. In the pestle is a good one Tappet guidance with simultaneous safety release guaranteed.
- the ram is a switch stop, through which in one of the reverse positions a switch is operated.
- This switch stop actuates one, for example Part lock, several according to a proposal of the invention Part locks can be selected.
- the push rod reaches its rear Position, the switch is closed and one of several options selected assembly part lock opened.
- the assembly part is released and provided in the feed channel until the ram is moved to the front position and the plunger feed the assembly parts to the tools.
- the simple control of the pusher carriage provided with the feed tappets via a push crank reduces the energy, assembly, adjustment and Maintenance expense of a device for feeding assembly parts and also reduces the speed at which the plunger hits the mounting parts to be supplied. It is easily possible that To control the ram so that the ram is directly behind the insertion point Feed channel reach its rearmost reverse position. The impact speed is then almost zero. The rest time required for inserting the parts is in a simple manner by the design of the radius Provide the provided guide curve on the ram. The movement speeds can move due to the shortened paths of the Parts are reduced.
- the schematic representation of a machine shown in Figure 1 for preparation of rivets, push buttons and the like shows the arrangement of a device for feeding assembly parts into the overall system.
- the attaching machine 1 comprises an upper tool 2 and a lower tool 3 as well a drive 4.
- the drive 4 becomes the coupling member 5 for the upper tool driven and via a lever 6 rotating about an axis 7 and one Link arm 8 and a plunger of the upper punch 9 moves up and down.
- a holding tool 10 is arranged in the area of the upper punch 9.
- a spring 12 in a retracted position is biased, via a gear disc 13 with which a cam 14 is connected, also stroke-controlled by a lever 16.
- Feed rams 19 are arranged on a ram 20 which is advanced by means of a push crank 21 and is withdrawn.
- the slide crank 21 a roller 23 arranged in a guide curve 22 of the ram expires.
- the guide curve 22 has a radius so that practically no power transmission within an angle f that is adjustable take place between the roller 23 and the ram 20. This will defines the rest time in which the ram 20 without feed in one Reverse positions persisted. This rest period can be used to insert assembly parts can be used in feed channels, not shown.
- the ram 20 has in the embodiment shown, two tappet guides 24, in which Ram 19 are used. For this purpose protrude into the tappet guides 24 Locking cams 25.
- the locking cams 25 are through the springs 26 are spring-loaded and are preloaded by an adjusting bolt 27 or penetration depth adjustable.
- On the plungers 19 are corresponding Locking grooves 28 formed.
- the locking cams are by cylindrical rollers, dowel pins or arranged at the lower end Balls 29 formed, which engage in the locking grooves 28 of the feed plunger 19.
- the tappet 19 in the plunger guide 24 is pushed in.
- stop pins 35 causes the plunger 19 to be pushed back into its locking position when the ram 20 moves to the rear reverse position.
- the ram 20 is advantageously by a with a guide curve provided plate, on which by the application of im essential angled parts tappet guides are formed.
- tappet guides are formed.
