Further, below the conveyor 30, an unloading belt conveyor 54 is provided in parallel, which is formed in the same direction as the conveyor 30, has the same width, and is slightly longer at the front and back, and moves in the opposite direction to the moving direction of the conveyor 30. I'm starting to do that.

The present invention is an automatic skewering device configured as described above.

The operation of the automatic skewering device described above will be explained based on FIGS. 6 and 7.

The meat pieces 44 prepared in advance are conveyed to the conveyor 3.
The skewers 3 are arranged on a fixed tray 34 fixedly fixed at regular intervals on the top of the hopper 1, and the skewers 3 are placed in a hopper 1 for storing skewers with the tips of the skewers aligned in the direction of the conveyor 30.

When the start button (not shown) is pressed, the motor 33
The rotation of the first sprocket 31 rotates the clamp cam 37 integrated with the third sprocket 36 via the transmission string 35.

On the other hand, the rotation of the first sprocket 31 is transmitted to the second sprocket 32 via a transmission string 32a.
transmitted to. The conveyor 30, which is provided with a Geneva mechanism (not shown) on the shaft of the second sprocket 32, is operated in tact at regular intervals.
When the conveyor 30 stops, that is, the piece of meat 4
While the fixed tray 34 on which 4 is placed is stopped at the fixed position, the clamp cam 37 rotates and the cam surface 37
a pushes down the clamp lever 42 and the movable tray 4
3 is combined with the fixed tray 34 with the piece of meat 44 sandwiched therebetween. The protrusion 3 of the first cam 38 in the combined state
8a is the operating lever 40 of the automatic skewering switch 40
Activate a to turn on the automatic skewering switch 40. When the switch 40 is turned on, the motor 46 of the automatic skewering device 45 shown in FIG. 6 rotates. As the motor 45 rotates, the pushing lever 49 rotates in the direction shown by the arrow b via the disc 47 and the rod 50.

A skewer pushing member 53 is rotatably fixed to the free end of the extrusion lever 49, and is designed to slide along the guide trough 52. The skewer 3 placed on top is pushed out by the skewer pushing member 53 toward the through holes 43a, 34a of the trays 43, 34, which are stopped on the conveyor 30 while holding the piece of meat 44 between them. Skewer.

After skewering, the extrusion lever 49 returns to the position shown in FIG. 6, and the motor 46 is stopped by a limit switch (not shown).

On the other hand, when the aforementioned start button (not shown) is pressed, the solenoid 17 pushes out the movable part 18 as shown in FIGS. 1 to 5.

The movable part 18 has an actuating member 19 in a vertical direction.
is fixed and a guide roller 20 is rotatably provided at its upper end, so that the solenoid 17 is activated and the actuating member 19 moves to the position shown by the two-dot chain line in FIG. As a result, the second swinging member 13 swings about the support shaft 15 to the position shown by the two-dot chain line. Therefore, the second swinging member 13
A protruding piece 16 fixed integrally with the hopper 1 moves in and out of a long hole drilled in the bottom plate 2 of the hopper 1 to give swinging motion to the skewer 3 so that the skewer 3 is smoothly introduced into the skewer guide channel 6. It's summery.

On the other hand, as shown in FIG.
By the movement of the swinging member 13, the second swinging member 13
The lever 21, one end of which is engaged with the lever 21, moves to the position shown by the two-dot chain line in FIG. Therefore, the sliding member 23, whose one end is engaged with the other end of the lever 21, slides along the support member 24.

A pawl 26 is rotatably provided at the other end of the sliding member 23 by a short shaft 25, and its tip is engaged with a pawl wheel 27 coaxially integrated with the skewer drum 4. Since the pawl 26 is given a rotational behavior in the direction of pressing against the ratchet wheel 27 by the compression spring 29, the skewer drum 4 is moved one tooth at a time by the swinging of the sliding member 23. Rotate in the direction shown.

Each time the skewer feeding drum 4 rotates, the skewer guide trough 6
The first swinging member 11, which is provided slightly protruding from the circumferential surface of the skewer feeding drum 4, comes into contact with the leading skewer 3 of the skewers 3 arranged in the drum 4, swings the skewer 3, and moves the skewer 3 into the skewer guide trough 6. The skewer 3 is smoothly dropped into the skewer feed groove 10 by preventing the so-called bridging phenomenon in which the skewers become entangled with each other at the exit.

Each time the solenoid 17 is actuated, the skewer drum 4 is fed the skewer 3 into the skewer groove 10 in the direction indicated by the arrow a.
When the skewer 3 rotates in the direction shown in FIG. 1 and the skewer feed groove 10 is positioned above the guide groove 52, the skewer 3 falls from the skewer feed groove 10 and is placed on the guide groove 52.

The pieces of meat 49 arranged on the fixed tray 34 through the above-described process are automatically skewered, then fall onto the conveyor 54 and are taken out in the direction shown by the arrow.

In an automatic skewering device, even if the skewering action is finished, the device does not stop immediately and starts the second operation.
The protrusion 39a of the cam 39 is the fixed position stop switch 4
The clamp cam 37 is rotated by the action of a relay (not shown) until it reaches a position where the first operating lever 41a is activated, and the device comes to a complete stop when the clamp lever 42 is fully raised.

As described above, the automatic skewering device of the present invention is very efficient compared to conventional devices because the skewers are placed in the hopper, the pieces of meat are arranged on the fixed tray, and simply by pressing the start switch, the skewers are automatically skewered and taken out. be. Furthermore, by combining this system with an automatic skewer-grilling device, an innovative automatic skewer-grilling system can be established.
