Summary of the invention
The present invention relates to a kind of utensil of squeezing into that is used for immobilising device is squeezed into workpiece; Has a housing; Be configured with a handle on this housing and in this housing, be provided with a housing region that is used for fixing device, and having an ejecting mechanism that is used for fixing device.
According to the present invention, a kind of utensil of squeezing into that is used for immobilising device is squeezed into workpiece is proposed, have a housing; Be configured with a handle on this housing and in this housing, be provided with a housing region that is used for these immobilising devices, and having an ejecting mechanism that is used for these immobilising devices, wherein: be provided with a cutoff device; When the immobilising device that exists in the housing region is less than one first minimum; This cutoff device causes the ejecting mechanism shutdown, and wherein, this cutoff device comprises at least one first grating; This grating is discerned the existence of immobilising device in the housing region of immobilising device; With first grating one second grating is set with separating spacing, can detects the reaching of second minimum of immobilising device by this second grating, this second minimum is greater than said first minimum.
According to the present invention; A kind of utensil of squeezing into that is used for immobilising device is squeezed into workpiece is also proposed; Have a housing, be configured with a handle on this housing and in this housing, be provided with a housing region that is used for fixing device, and having an ejecting mechanism that is used for these immobilising devices; Wherein, Be provided with a cutoff device, this cutoff device can be through component inventory slide closed electrical contact and an optical grating constitution, wherein by one; When the little immobilising device storage level of also have confirming in the housing region of immobilising device is available, trigger in said electrical contact and the said grating, when the immobilising device that in housing region, exists is less than minimum, trigger in said electrical contact and the said grating another and cause ejecting mechanism to be shut down.
According to the present invention; Propose a kind of utensil of squeezing into that is used for immobilising device is squeezed into workpiece, have a housing, be configured with a handle on this housing and in this housing, be provided with a housing region that is used for these immobilising devices; And has an ejecting mechanism that is used for these immobilising devices; Wherein: be provided with a cutoff device, when the immobilising device that exists in the housing region was less than a minimum, this cutoff device caused the ejecting mechanism shutdown.
The present invention proposes, and a cutoff device is set, and the immobilising device that this cutoff device exists in housing region causes ejecting mechanism to be shut down when being less than minimum.Wherein, the quantity that constitutes the immobilising device of this minimum can be adjusted and/or especially advantageously adjusted by the operator who squeezes into utensil in cutoff device inside in advance.This cutoff device can comprise an optical unit, and grating for example is placed in no function, when especially being turned off when being lower than the minimum of immobilising device and when a signal based on this optical unit makes ejecting mechanism, and this optical unit can be triggered.In addition, this cutoff device can comprise an electrical contact, when being lower than the minimum of immobilising device and when since the signal of this electrical contact make ejecting mechanism be placed in no function, when especially being turned off, this electrical contact is closure preferably.Therefore reliably avoid the useless activation of ejecting mechanism.
In addition, in two kinds of modification, can stipulate:, can trigger a pre-alarm when operational immobilising device during near minimum.Also can consider the combination of two kinds of modification of cutoff device of cutoff device and the electricity of optics.Therefore, can be for example when also having the little immobilising device storage level of confirming available, trigger grating, when last immobilising device is used, triggers and electrically contact, this electrically contacts and then causes the ejecting mechanism shutdown then.Also can consider a kind of opposite modification, in this modification, for example when the little immobilising device storage level of also have confirming is available, trigger and electrically contact that when last immobilising device is used, trigger grating, this grating causes ejecting mechanism to be shut down then.Because the structure space that does not need or need add is hardly squeezed in the utensil so cutoff device can easily be integrated in.
Consume situation and avoid also can being provided with empty the impact storage level indication utensil except discerning immobilising device in time; The immobilising device that this storage level indication utensil indication also has in squeezing into the component inventory of utensil is the quantity of clip, pin and nail for example, so that can replenish in time.This is helpful to the user, if this user utilizes this to squeeze into utensil work on the position that is difficult to touch or on ladder, for example when mounting groove-push pedal frame.
Cutoff device can comprise at least one first grating in preferred first scheme, and this grating is discerned the existence of immobilising device in the housing region of immobilising device.This grating is positioned in the housing region, especially in the clip pit shaft on the position of an explication, and directly is not connected with this housing region or clip pit shaft with advantageous manner.Survey the existence of immobilising device by a beam optical.If do not recognize immobilising device, then can trigger a signal, this signal can be continued to handle by an electronic installation.Can preferably use different photoelectric cells.The single channel grating is favourable, and wherein transmitter and receiver are placed in the height place in aperture in the both sides in zone to be detected in the housing of oneself.The single channel grating is used in passive work, promptly when directly light path is interrupted, is used.Therefore, when component inventory also is filled with sufficient immobilising device with this state recording on the receiver diode, and light through the time, when promptly lacking immobilising device, the electronic installation through the correspondence configuration produces and turn-offs pulse.Reflecting grating also is suitable.This reflecting grating is according to the principle work of folded light beam.Transmitter and receiver are installed in the same housing.The reflector that immobilising device perhaps is installed in the component inventory opposite side can cause reflection in this case.Reflection light detector also is suitable in addition.Transmitter and receiver are arranged in the same housing in these reflection light detectors, but what analyzed is not interruption but the reflection of light beam on an object of light beam.When immobilising device reflected enough light to receiver, immobilising device was identified.Because the distance of the connection between transmitter and the immobilising device here is little, therefore can advantageously cancel the aperture that is used for seeing through light that is positioned at first opposite, aperture in the component inventory.The fiber optic tool grating that can as reflection light detector, use in addition, is suitable.Here particularly advantageously be: incident light hole mouth and light outgoing aperture can be constructed very for a short time, for example have the diameter below the 1mm, and for example can be positioned at the scope of clip width.
First grating can preferably interrupt when having immobilising device and be closed when lacking immobilising device.Interruption is meant that receiver does not receive the signal of transmitter, and closure is meant that receiver receives the signal of transmitter, if receiver should not receive signal when having immobilising device.If immobilising device constitutes the part of grating, as as reflector, then the configuration of interruption/closure is opposite.Grating does not interrupt when having immobilising device, and grating is closed when immobilising device.This results from the concrete grating kind of selecting of professional.Corresponding shutoff pulse can be transmitted to ejecting mechanism.
The impactor tool advantageously comprises a sliding unit that is used for fixing device, and this sliding unit is set for the interruption or the release of first grating.An aperture can be set on this sliding unit, this aperture is hidden by these immobilising devices when having immobilising device for this reason.To for example receiver emission, wherein this light beam passes the aperture that on diameter, relatively is provided with each other on the sliding unit to the light beam of grating by transmitter.In this case, the apertures of storehouse part is aimed in the aperture of sliding unit.If immobilising device is arranged then this light beam interrupts.If in the zone in these apertures, do not have immobilising device, then light beam can pass through, and grating is closed.The preferred position of selecting the aperture like this, feasible penult immobilising device at least can be used the light beam detection of focusing.Because immobilising device is on the same position in its storehouse pit shaft of housing region all the time, therefore when using the clip of identical wire thickness, turn-offs pulse and also can be connected with digital electronic unit.This means, when determined remaining immobilising device minimum, on suitable incident report device, report occurred and before immobilising device uses up, give a warning.This incident report device for example can be the display on the housing, utilizes this display can display text, and perhaps this incident report device is a light-emitting section with the length that reduces pro rata with immobilising device quantity, voice signal or similar signal.If component inventory is removed in order to fill purpose, then grating or its receiver diode can additionally use the shutoff pulse recording of preparation to get off as being used to this state.
Propose for this reason, squeeze into utensil and comprise an end stops that is used for sliding unit, this end stops and first grating are installed with being separated by a spacing, when being lower than the minimum of immobilising device, arrive this spacing.First minimum preferably 1 is corresponding to last immobilising device in the component inventory.If this last immobilising device is used, then recognizes this state and ejecting mechanism is shut down.
Can with the first grating partition distance second grating is set, can detect second minimum that reaches immobilising device by this second grating, this second minimum is greater than first minimum.For example second minimum can be 10, when triggering first alarm by second grating, also has ten immobilising devices thus.Distance between the grating is preferred to be selected like this, makes and can detect significant immobilising device surplus.If two gratings are set, can be correspondingly in housing region, preferably in component inventory, on the height of each grating, the aperture is set.Can be arranged on aperture relative on the diameter according to the type of selected grating in case of necessity, if the light beam of these gratings passes component inventory.An aperture of transmitter-receiver device one side just can be enough in the reflection unit of speaking of in the above.Aperture on the sliding unit can be simple boring or also can be configured to elongated hole, settle this two transmitters or receiver in the end of this elongated hole respectively.In case second grating of back sends signal: reach first minimum of immobilising device, 10 clips for example, then as long as the elongated hole of sliding unit uses along with the continuation of residue immobilising device to the previous dynasty first grating move, second grating just remains closed.In case this elongated hole arrives first grating, then first grating is closed and send the shutoff pulse signal.In this structure, in housing region, also only there is the information of a small amount of immobilising device under the situation of current interruptions, also still to keep, because second grating is closed all the time when reclosing.
An incident report device advantageously can be set, and this incident report device triggers an alarm when second grating is closed.Therefore can advantageously send early warning to the user.
In addition, a counting device can write down once further using of immobilising device when second grating is closed, and therefore can advantageously inform the information of squeezing into utensil operator occupied state and/or immobilising device consumption by this counting device.
A kind of utensil of squeezing into that is used for immobilising device is squeezed into workpiece of second preferred version regulation; It has a housing; Be configured with a handle on this housing and in this housing, be provided with a housing region that is used for these immobilising devices, and having one and be used for these immobilising device ejecting mechanisms.Squeeze into the unit and advantageously have a cutoff device, this cutoff device is by constituting through the closed electrical contact of component inventory slide.Can avoid the empty damage of impacting and avoiding workpiece or surface of the work thus through the use of timely identification immobilising device.
Can be advantageously provided the spring of a driving element storehouse slide at housing region, it has the rear suspension of the anterior suspension arrangement and an electric insulation of an electric insulation.Can when having immobilising device, avoid electrically contacting and when component inventory is empty, just reaching the contact of expectation thus.If the component inventory slide is with respect to the spring electric insulation when in housing region, having the minimum immobilising device, can especially advantageously reach this point.From this respect; Be interpreted as being used for a suspension arrangement of spring for " anterior with the suspension arrangement rear portion "; Wherein, anterior suspension arrangement is arranged on the side towards the clip outlet of spring, and the suspension arrangement at rear portion is arranged on a side that deviates from the clip outlet of spring.
Propose in addition, squeeze into utensil and have a contact finger, this contact finger is supported on the front of component inventory slide and when being lower than predetermined immobilising device minimum, makes electrical contact closed.Preferred this contact finger is set up conductive the connection through sliding unit and spring.
As possibility, a zone of this contact finger and housing region can form electrical contact.Preferably this is the bottom of component inventory, and a suitable contact-making surface and this contact finger are in interlocking in this bottom.
Advantageously, contact finger is adjustable on its length.Exist close related in immobilising device consumption and sliding unit, especially component inventory slide and housing region or between the contact of the end stops in the component inventory.Can compensate the error of squeezing in the utensil simply through this adjustable property.At this, the calibration of contact finger can be carried out and/or undertaken by the operator who squeezes into utensil to partial automation.
In addition arrangements of electric connection can be set in housing region, these jockeys are electrically connected when electrical contact is closed.The electric current supply of electric cutoff device preferably can be the small voltage of several volts that the operator is safe from danger.This voltage signal can flow to an incident report device.The LED (light emitting diode) that can for example glimmer when lacking immobilising device in component inventory or in the housing region perhaps carries out an acoustical signal, like a buzz or a voice output.
