Work machine
A work machine provided with slider that moves in a specified direction, and two mounting heads and attached to the slider is provided. The slider has holding, and first and second attachment sections to which a mounting head is attached. The first attachment section is provided on the holding plate, and the second attachment section is provided on the holding plate so as to be changeable between any distance which is a distance between the first and second attachment sections. Accordingly, it is possible to change the distance between attachment sections and two wide work heads may be mounted on the slider. In a case in which the types of the two work heads are not to be changed, it is possible to change the spacing between the two work heads. By changing the spacing between the two work heads, interference between the work heads may be prevented.
1. A work machine comprising:
a slider that is held on a holding section so as to be movable in a specified direction; and
two work heads that are detachably attached to the slider;
wherein the slider has
a main body,
a first attachment section that is provided on the main body and to which one of the two work heads is attached, and
a second attachment section that is provided on the main body at a set distance from the first attachment section so as to be changeable between any one of multiple of the set distances that are set in advance, and to which the other of the two work heads is attached, and
wherein the work machine further comprises:
multiple detected sections provided on one of the main body and the second attachment section; and
an attachment section spacing distance detector that is provided on the other one of the main body and the second attachment section, has multiple sensors which detect the multiple detected sections, and detects the distance between the first attachment section and the second attachment section by the detection of at least one of the multiple detected sections by two of the sensors out of the multiple sensors.
2. The work machine according to claim 1 , wherein the quantity of the multiple sensors is smaller than the quantity of the multiple set distances.
3. The work machine according to claim 1 , wherein
the multiple detected sections are provided on one of the main body and the second attachment section spaced at a distance extending in the specified direction;
the multiple sensors are provided on the other one of the main body and the second attachment section spaced at a distance extending in the specified direction;
and the attachment section spacing distance detector detects the distance between the first attachment section and the second attachment section by the detection of the multiple detected sections by two sensors which are not adjacent to each other among the multiple sensors, or by the detection of at least one of the multiple detected sections by two sensors which are adjacent to each other among the multiple sensors.
4. The work machine according to claim 1 , further comprising:
a moving device that moves the slider in the specified direction;
a control device that controls operation of the moving device;
a stopper that limits the movement of the slider in the specified direction by being contacted by the stopper;
wherein the stopper changes the movement amount of the slider in the specified direction based on the distance between the first attachment section and the second attachment section;
and wherein the control device has
a storage section that stores the movement amount of the slider in the specified direction based on the distance between the first attachment section and the second attachment section,
a movement control section that acquires from the storage section the movement amount of the slider based on the distance between the first attachment section and the second attachment section that was detected by the attachment section spacing distance detector, and moves the slider towards the stroke end of the acquired movement amount of the slider, and
a determination section that determines whether the slider has contacted the stopper during movement of the slider by the movement control section.
5. The work machine according to claim 1 , further comprising:
a notifying device that notifies an operator in a case in which the distance between the first attachment section and the second attachment section detected by the attachment section spacing distance detector is different from a planned distance between the first attachment section and the second attachment section.
6. The work machine according to claim 1 , wherein the multiple set distances are set based on at least a dimension of each of the two work heads, and a dimension of a work target piece of each of the two work heads.
