Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for cutting out a trolley storage line in article storage equipment and article transport equipment.

In the conventional cutting device, as shown in Fig. 1, a cylinder c is provided in each of the leading truck stopper a and the trailing truck stopper b, and the cylinders c are operated separately to sequentially cut out the trucks d. In such a cutting device, the storage pitch is the stopper a,
Since it is limited by the min size between b, this becomes a factor that deteriorates storage efficiency, and this is particularly noticeable when the unit height is suppressed. In addition, since two cylinders c are used and the timing of the operation of each cylinder c is electrically controlled, the number of control points (return timing of the stopper b for the following bogie) increases, leading to problems in terms of cost increase and reliability. I was getting used to it.

The present invention was developed in view of the above-mentioned circumstances, and includes a fixed member at the leading bogie cutting position of the bogie storage line, and a fixed cam plate at the following bogie waiting position behind the leading bogie cutting position determined by the storage pitch. A movable cam plate is disposed on the sides of the fixed member and the fixed cam plate, the distal end of which is connected to the tip of the rod of the cylinder so that the movable cam plate can be pushed out and retracted by the expansion and contraction movements of the cylinder. A stopper for a trailing truck is pivotally attached to a predetermined position behind the fixed member of the cam plate so that it is pushed up by the fixed cam plate when the movable cam plate is retracted, and the movable cam plate is attached to the fixed member. A stopper for the leading truck is pivotally mounted so that it is pushed up by the movable cam plate when pushed out, and the movable cam plate is arranged so that when the movable cam plate is retracted, both stoppers remain in the upright position at the same time. A device for cutting out a trolley storage line, characterized in that it is formed into a required length.
This is related to.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 2, reference numeral 1 denotes a truck having an engaging protrusion 2 at its lower part, which is arranged in alignment with the storage line. Located at the beginning (left end in the diagram)
A fixing member 4 is disposed on the floor 3 below the bogie 1, that is, at the leading bogie cutout position, and a fixing member 4 is disposed on the floor 3 at a position separated from the fixing member 4 by a distance determined by the storage pitch, that is, the trailing bogie. A fixed cam plate 5 is provided at the standby position, and a movable cam plate 7 whose distal end is connected to the rod tip of the cylinder 6 is attached to the fixed member 4.
It is constructed so that it can reciprocate on the side of the fixed cam plate 5.

A stopper 11 for the leading truck, which has a stopper roller 9 at the upper apex corner of the triangular ring plate 8 and a cam roller 10 at the lower apex corner, can be rotated about the central apex corner of the ring plate 8 as a fulcrum. A pin 12 is attached to the side of the fixed member 4, and a stopper 11' for the trailing truck, which is composed of a ring plate 8', a stopper roller 9', and a cam roller 10' like the stopper 11 for the leading truck, is attached to the movable cam plate. A pin 12' is attached to a protrusion 7' at the upper center of the cylinder 7, so that when the cylinder 6 is extended, the leading bogie stopper 11 can stand up on the movable cam plate 7, and when the cylinder 6 is retracted. The construction is such that the stopper 11' for the following bogie can stand up on the fixed cam plate 5 when the vehicle is pushed up. Note that the corners of the movable cam plate 7 and the fixed cam plate 5 are provided with stoppers 11,
The cam rollers 10, 10' of 11' are chamfered so that they can be easily transferred. In addition, the movable cam plate 7 is formed to a required length so as to have a flat portion α at the tip (see FIG. 3) in order to maintain the time during which both stoppers 11 and 11' are upright at the same time. ing.

Next, the operation will be explained.

FIG. 2 shows the storage state of each truck 1, in which the cylinder 6 is extended to push out the movable cam plate 7, the stopper 11 for the leading truck is erected at the tip of the movable cam plate 7, and the stopper roller of the stopper 11 is raised. At 9, the leading bogie 1 is stopped and held through engagement with the engaging portion 2 and mechanically locked, while the stopper 11' for the following bogie is disengaged from the fixed cam plate 5 and is stopped by its own weight. It's hanging down.

In this state, when the cylinder 6 is caused to contract by the cutting request signal, the movable cam plate 7
is drawn in. When the movable cam plate 7 is retracted, the cam roller 10' of the stopper 11' for the following bogie engages with the fixed cam 5, and the stopper 1
1' is made to stand up on the fixed cam 5. However, in this state, since the movable cam plate 7 has a flat portion α at its tip, the leading truck stopper 11 stands up at the tip of the movable cam plate 7 to stop the leading truck 1, and both stoppers 11 , 11' both maintain a mechanical lock state. (See Figure 3). When the movable cam plate 7 is further retracted, the stopper 11' for the following bogie is rolled on the fixed cam plate 5 by the cam roller 10', and the stopper roller 9' abuts and engages with the engaging portion 2 of the following bogie 1. The position of the following truck 1 is maintained and mechanically locked. After a slight delay from the engagement between the following bogie stopper 11' and the following bogie 1, the movable cam plate 7 and the leading bogie stopper 11 become disengaged, and the stopper 11 hangs down due to its own weight, causing the leading bogie 1 to Release the hold and move the first trolley 1
(See Figure 4).

FIG. 5 shows the front packed state of each of the following carts 1,
When the leading truck 1 is cut out as described above, the cylinder 6 is again operated to extend due to the cutting completion signal, the movable cam plate 7 is pushed out, and each of the following carts 1 moves forward together with the stopper 11' for the trailing truck. At the beginning (see FIG. 5), the leading truck stopper 11 is raised up by the movable cam plate 7 before the trailing truck stopper 11' and the fixed cam 5 are disengaged. When the stopper 11' for the trailing truck is removed from the fixed cam plate 7, each of the following trucks 1 moves forward and is held in contact with the stopper 11 for the leading truck and is mechanically locked (see FIG. 1).

By repeating the above operations, the carts 1 can be reliably cut out one by one.

It should be noted that the present invention is not limited to the above-mentioned embodiments; for example, both stoppers do not necessarily need to be provided with rollers, and other changes may be made without departing from the gist of the present invention. .

As described above, according to the present invention, (i) the storage pitch of the cart can be set regardless of the size of the cutting device itself;

(ii) 1 due to the combination of movable cam plate and fixed cam plate
Since each stopper can be interlocked during one stroke of the base cylinder, cylinder control is very simple.

(iii) Since the number of electrical control points is small and the mechanical structure is simple, reliability and economic efficiency are improved.

(iv) Since the other stopper is raised before one stopper is released, each truck can be cut out safely and reliably, and there are no mistakes in cutting out.

(v) Cost reduction can be expected.

It can produce excellent effects such as
