A detection plate 33 is provided on the bottom of the box-shaped frame 24, and the detection plate 33 detects the presence or absence of the block member b in the case 9. The detection plate 33 has a size sufficient to cover the entire horizontal area in which the block members b are arranged in the case 9 so as to be aligned in the length direction and the width direction.
Further, the detection plate 33 is hung on the side frame 24b via two parallel links 34 so as to be vertically movable at a side end portion parallel to the side frame 24b. The parallel links 34 are connected to each other by a connecting rod 35 parallel to the front frame 24a and the rear frame 24c. 2 of each parallel link 34
One end on one front frame 24a side is slidably fitted into two elongated holes 36, 36 formed on the side frame 24b.
One end of the link 34 in the ring 36 can move horizontally when the link 34 extends or contracts in the vertical direction.

The push-out plate 32 has a roller 39, and this roller 39 pushes up the detection plate 33 when the push-out plate 32 is located below the detection plate 33 and pushes up the detection plate 33 from the upper surface of the block member b. Separate the lower surface of. By doing so, the pushing plate 32 can smoothly push the block member b. The extruded plate
When 32 is located below the horizontal portion 33c of the projecting plate 33a, the detecting plate 33 descends until it contacts the upper surface of the block member b. At this time, the vertical plate 37 is the photo sensor.
It blocks the light of 38. That is, in this state, the photo sensor 38 detects the presence of the block member b.
If all the uppermost block members b are extruded and the extruded plate 32 is returned to the initial position (the lower position of the protruding plate 33a), the detection plate 33 is placed at the height position of the block member b. Therefore, the vertical plate 37 separates from the photo sensor 38 by descending one step. At this time, the photo sensor 38 outputs a signal for driving the drive motor 26, and the box-shaped frame 24 descends.

That is, the detection plate 33 descends until it comes into contact with the upper surface of the block member b located at the height position of the next step, and when the box-shaped frame 24 descends later, the vertical plate 37 Drive into the sensor 38 and drive
The lowering of the box-shaped frame 24 by 26 is stopped.
In this way, the push-out plate 32 completes the preparation for pushing out the block member b at the next height position. The vertical plate 37, the sensor 38
Constitutes a vertical movement detector 57 for detecting the vertical movement of the detection plate 33, and the detection plate 33, the parallel link 34, the connecting rod 35 and the vertical movement detector 57 constitute a block member detecting means 58.

An oscillating plate 42 is provided inside the front frame 24a (FIGS. 1 and 4). In the oscillating plate 42, a block member b, which is an example in the width direction, is extruded from inside the case 9 onto the conveyor 13 to form a box. It is detected whether or not it is taken out of the frame 24. A supply roller 43 is rotatably provided at the lower portion of the front frame 24a (FIG. 4), and the supply roller 43 assists in taking out the block member b onto the conveyor 13. The supply roller 43 has a pulley 44 at one end thereof.
Is connected to the drive motor 45 via an endless belt 46. A photo sensor 47 is provided outside one end of the front frame 24a, and the photo sensor 47 supports the conveyor 13 as shown in FIGS.
It cooperates with a vertical plate 48 which is erected on.

That is, when the upper end of the vertical plate 48 is inserted into the photo sensor 47, the vertical movement of the conveyor 13 is stopped at substantially the same height as the supply roller 43 in FIG. At the same time, the photo sensor 47 moves the extrusion plate 32 and rotates the supply roller 43 to move the block member b to the conveyor 13.
Outputs a signal for carrying up. When one row in the width direction on the frontmost end side of the block member b is pushed onto the conveyor 13, the block member b swings the swing plate 42 upward and the plate 49 connected thereto to swing. Plate 49
Is taken out from the inside of the photo sensor 50 (FIG. 4). The plate 49 is usually provided with a photo sensor 50 by a spring 51.
It is located inside. The photo sensor 50 is a supply roller 43.
And the conveyor 13 is moved upward.

A stopper mechanism 52 (FIG. 1) is provided at the other end of the front frame 24a on the opposite side of the photo sensor 47, and the stopper mechanism 52 is provided at the end of one row of block members b placed on the conveyor 13. This is for preventing the block member b from falling in the width direction. The stopper mechanism 52
Has a swing lever 52a, a link 52b and an operating lever 52c. The swing lever 52a is biased inside the front frame 24a by a spring (not shown), and the operating lever 52c
Rotates when the lower end of the conveyor frame 53 comes into contact with the operating lever 52c and causes the swing lever 52a to swing outside the front frame 24a via the link 52b.

Next, the operation will be described. When the conveyor 13 comes down and the vertical plate 48 is inserted into the photo sensor 47, the conveyor 13 is stopped at almost the same height as the supply roller 43, and the swing lever 52a of the stopper mechanism 52 is output to the outside. . At this time, the photo sensor 47 outputs a signal to operate the pushing plate 32 and the supply roller 43. That is, when the conveyor 13 comes to the position shown in FIG. 7, the push-out plate 32 pushes and moves the last end of the last row of the block member b by the same distance as the length of the block member b, and the feed roller 43 is moved. In cooperation with each other, the row of the block members b on the frontmost side of the block member b in the width direction is taken out onto the conveyor 13 outside the box-shaped frame 24. Then, after the row of block members b on the frontmost end side is completely fed onto the conveyor 13, the pushing plate 32 is stopped by the action of the moving length detecting means 55. At the same time, when the block member b is taken out, the swing plate 42 rides on the upper surface of the block member b and swings, and the plate 49 resists the spring 51 and the photo sensor 50.
When it is output from the inside, the photo sensor 50 stops the rotation of the supply roller 43 and outputs a signal for moving the conveyor 13 upward.

As shown in FIG. 8, the bottom plate 12c of the case 9 has a step 12d facing the conveyor 13 side. If there is no step 12d, block member b
As shown in FIG. 9, the front end of the upper block member b (1) is caught on the rear end of the lower block member b (2) due to the variation in the thickness or the diameter of the block member (see the arrow), and the block is smoothly blocked. In some cases, the member b (1) cannot be extruded,
Since the dimension h of the step 12d is larger than the variation of the thickness or diameter of the block member b, as shown in FIG. 8, the rear end of the block member b (2) is located at the rear end of the block member b (1). It is possible to prevent the trip from going up as shown in FIG. 9 by always sinking downward from the front end. Therefore, as described above, the block members b are not caught by each other, so that the block members b can be smoothly pushed to the conveyor 13 side.
