BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0018]
FIG. 1 is a side view schematically showing one embodiment of the trolley fall prevention structure of the present invention in a closed state, and FIG. 2 is a simplified view of one embodiment of the trolley fall prevention structure of the present invention in an open state. FIG. 3 is a partially enlarged view of FIG. 1. Note that the term “horizontal” in this specification refers to a plane parallel to the ground.
[0019]
As shown in FIGS. 1 and 2, the trolley fall prevention structure 4 is provided below the landing machine, and includes a locking member 5, a fixing member 6, a holding member 7, a spring 8 as an elastic member, And a release member 9.
[0020]
As shown in FIG. 3, the locking member 5 includes a support portion 5a extending vertically downward from the landing machine, a curved portion 5b curved below the support portion 5a, and a curved portion 5b below the support portion 5a. And a protruding portion 5c that protrudes horizontally from.
[0021]
Further, the locking member 5 is provided to be vertically movable. That is, a part of the support portion 5a comes and goes.
[0022]
As shown in FIG. 3, the fixing member 6 is provided on the support portion 5 a of the locking member 5 so as to project once in the curved direction of the locking member 5, and further, the lower end 6 a is horizontal.
[0023]
As shown in FIG. 3, the holding member 7 is rotatably provided by the pin 13 on the curved portion 5 b of the locking member 5. In the closed state, the holding member 7 is provided so that the end portion 7a is brought into contact with the tip of the projection 5c of the locking member 5, and the projection 7b is horizontally projected on the opposite side. At this time, the end 7a of the holding member 7 is in contact with only the tip of the protruding portion 5c of the locking member 5, and is curved so that the meat hanging moving trolley 3 can be fitted. On the other hand, when the holding member 7 is in the open state, the end 7a is not in contact with the tip of the protrusion 5c of the locking member 5, and the protrusion 7b protrudes below the horizontal on the opposite side.
[0024]
As shown in FIG. 3, two springs 8 are attached so that the lower end 6 a of the fixing member 6 and the protrusion 7 b of the holding member 7 are close to each other. That is, the trolley drop prevention structure 4 is usually applied with a force by the biasing force of the spring 8 so that the tip of the protrusion 5c of the locking member 5 and the end 7a of the holding member 7 come into contact with each other. Is closed.
[0025]
The releasing means 9 has a support bar 9a extending vertically downward from the landing machine, and a horizontal bar 9b below the support bar 9a, and the protrusion 9b of the holding member 7 is held by the bar 9b. It is fixed in position so that it can be pushed or not pushed. That is, when the locking member 5 moves upward, the release means 9 pushes the protruding portion 7b of the holding member 7, so that the tip of the protruding portion 5c of the locking member 5 and the end of the holding member 7 are moved. A strong force opposing the biasing force of the spring 8 is applied so that the spring 7a does not come into contact, and as a result, the spring 8 expands and becomes open. On the other hand, the locking member 5 is positioned so that the release means 9 does not push the protruding portion 7b of the holding member 7, and the urging force of the spring 8 causes the protruding portion 5c of the locking member 5 to be compressed. Since the force is applied so that the portion and the end 7a of the holding member 7 come into contact with each other, the spring 8 contracts and is closed.
[0026]
Further, the releasing means 9 makes contact with the projecting portion 7b of the holding member 7 outside the position where the spring 8 is attached, so that even if the elastic force of the spring 8 is increased, it is held with a weak force by the leverage principle. The member 7 can be moved.
[0027]
Further, the position of the release means 9 is adjusted so as to push the protruding portion 7b of the holding member 7 when it comes on the transport rail 10 from which the meat hanging moving trolley 3 from which the hanging member 5 is to be removed is to be released. .
[0028]
Therefore, as shown in FIG. 1, the trolley fall prevention structure 4 can be closed when it is moving. It can be prevented from dropping from the stop member 5, and the worker can be protected from danger.
[0029]
On the other hand, as shown in FIG. 2, the trolley fall prevention structure 4 automatically opens the meat hanging moving trolley 3 when the meat hanging moving trolley 3 reaches the transport rail 10, and moves the meat hanging movable trolley 3 to the transport rail 10. Can be replaced.
[0030]
FIG. 4 is a partially enlarged view showing another example of the trolley fall prevention structure of the present invention.
[0031]
The trolley fall prevention structure 14 is provided below the landing machine, and includes a locking member 15, a holding member 17, a spring 18 as an elastic member, and a release member.
[0032]
As shown in FIG. 4, the locking member 15 includes a support portion 15a extending vertically downward from the landing machine, a curved portion 15b curved below the support portion 15a, and a curved portion 15b below the support portion 15a. And a projection 15d horizontally projecting from the curved portion 15b in a direction opposite to the projection 15c.
[0033]
As shown in FIG. 4, the holding member 17 is rotatably provided by the pin 23 on the curved portion 15 b of the locking member 15. The holding member 17 is provided so that, in the closed state, the end 17a is brought into contact with the tip of the projection 15c of the locking member 15, and the projection 17b is projected horizontally on the opposite side. On the other hand, when the holding member 17 is in the open state, the end portion 17a is not in contact with the distal end portion of the projection 15c of the locking member 15, and the projection 17b protrudes below the horizontal on the opposite side.
[0034]
As shown in FIG. 4, one spring 18 is attached so that the protrusion 15 d of the locking member 15 and the protrusion 7 b of the holding member 17 are separated from each other. That is, unlike the trolley fall prevention structure 4 of FIGS. 1-3, the trolley fall prevention structure 14 does not have a fixing member.
[0035]
Unlike the trolley drop prevention structure 4 shown in FIGS. 1 to 3, the release means is provided so as to be able to move up and down so that the projecting portion 17b of the holding member 17 can be pushed or not pushed. That is, when the release means moves downward and pushes the protrusion 17b of the holding member 17, the spring 18 prevents the tip of the protrusion 15c of the locking member 15 from contacting the end 17a of the holding member 17. A strong force is applied in opposition to the bias to return to the original position, and the spring 18 is contracted to be in an open state. Thereafter, when the release means moves upward and stops pushing the projecting portion 17b of the holding member 17, the urging to immediately return to the original position of the spring 8 causes the tip of the projecting portion 15c of the locking member 15 to be returned. The part and the end part 17a of the holding member 17 come into contact with each other, and the state is closed.
[0036]
Therefore, the trolley fall prevention structure 14 can be closed when it is moving, so that the meat hanging movement trolley 3 falls from the locking member 15 even when the body kicks with the hind legs. Can be prevented, and the worker can be protected from danger. On the other hand, the trolley fall prevention structure 14 can be opened when the meat hanging moving trolley 3 reaches the transport rail 10 and the meat hanging moving trolley 3 can be transferred to the transport rail 10.
[0037]
The elastic member is not particularly limited, as long as it can urge the holding member to press the holding member. Also, any number of the elastic members may be attached, and preferably two.
The trolley drop prevention structure of the present invention is applicable not only to a structure for preventing the trolley from falling, but also to another structure for preventing the transferred object from falling.
[0038]
【The invention's effect】
As described above, according to the present invention, since the elastic member urges the holding member so as to close the locking member with the holding member, the holding member can be closed. Falling can be prevented. Furthermore, the holding member can be strongly pressed against the locking member in the closed state by the elastic member, and the trolley can be reliably prevented from dropping.
