SOLUTION: Sprockets 3 are fixed to shafts 33 and 34, and a left and a right endless chain 23 are set over the sprockets. Each chain 23 is furnished with projections 7 at intervals with every two links, and a piece 9 is pivoted by a pin 10 on each projection 7 in such a way as capable of rotating round the pin 10. The piece 9 has an L-shape and is composed of a receptacle table 9a for placing of each flat bar 1 and a holding part 9b to hold the receptacle table 9a approx. horizontally, and when the chains move from up to down, the holding part 9b holds the receptacle table 9a horizontally whereon the falt bar 1 is placed. A flat bar receiving frame of a boiled fish paste manufacturing machine is installed alongside the chains 23. Under the frame 11, a roller 12 is installed for receiving flat bars 1 and is equipped at the peripheral surface with shallow grooves 13 for accommodation of flat bars 1 at a certain spacing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for stacking flat bars, which can be used for stacking flat skewers used for manufacturing bamboo fish.

[0002]

2. Description of the Related Art As shown in FIG. 1, in an automatic manufacturing process of bamboo fish, which is known as a specialty of Sendai, a fish skewer 1 is applied to a flat skewer 1 made of stainless steel, shaped into bamboo leaves, and then heated. Finally, pull out the skewer. In the manufacturing machine used for this, flat skewers are stacked in a frame, and the bottom skewer is successively extracted and sent out to a step of applying surimi. This work of stacking skewers in a frame is performed by a worker's hand, and mechanization has been desired.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a machine for automatically stacking flat skewers.

[0004]

According to the present invention, the upper and lower shafts are rotatably supported on a machine frame, sprockets are supported on these shafts, and a pair of left and right endless chains are suspended around these sprockets. The frame is rotatably supported by the link of the chain. These pieces maintain a horizontal position when descending with the chain, and carry a flat bar carried by another chain suspended on a sprocket mounted on the upper shaft on the top of the piece and carry it downward. When the tops hit the stacked flat bars, the tops rotate upward and the flat bars on the tops fall onto the stacked flat bars. In this way, the flat bars carried by another chain can be stacked one after another, and the stacked flat bars can be easily taken out from below.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 2 and 3, a machine frame 2 rotatably supports first to fourth shafts 31 to 34. FIG. The sprockets 3 are fixed to both sides of the first and second shafts 31 and 32, respectively, and the two left and right endless chains 21 are suspended between these sprockets. First shaft 31
Is low and the second shaft 32 is at a high position, so that the chain 21 is inclined as shown in FIG.

[0006] The sprocket 3 is also fixed between the second and third shafts 32 and 33, and two endless chains 22 are suspended between them. The second and third axes 32, 33 are at the same level and the chain 22 is horizontal. Similarly, the sprocket 3 is fixed to the third and fourth shafts 33 and 34, and the left and right two endless chains 23 are suspended. The fourth axis 34 is directly below the third axis 33 and the chain 23 is vertical. The electric motor 5 is attached to the second shaft 32, and the first to fourth shafts 31 to 34 and three chains 21 to 23 are set.
Is driven to rotate in the direction indicated by the arrow in FIG.

First and second sets of chains 21, 2
Reference numeral 2 denotes a roller chain, as shown in FIG. 4, provided with protrusions 7 on the chain links 6 at every third position, and put the flat skewer 1 on the protrusions of the left and right chains, or push the flat skewer with the protrusions To

As shown in FIG. 5, a third set of chains 23 (also a roller chain) is provided with projections 7 on every other link 6 and a piece 9 on each projection 7 with a pin 10. To allow the top 9 to rotate about the pin 10. The top 9 is L-shaped and comprises a receiving portion 9a for placing the flat skewers 1 and a holding portion 9b for keeping the receiving portion almost horizontal. When the chain moves from top to bottom, the holding portion 9a is provided. 9b keeps the cradle 9a horizontal and places the flat skewers 1 on the horizontal cradle.

A frame 11 for receiving the flat skewers 1 is provided for the bamboo grass kamaboko making machine along the third set of chains 23. The frame body is, as shown in FIG. Below the frame 11, there is a transport roller 12, and on the peripheral surface of the roller 12,
Shallow grooves 13 in which the flat skewers 1 are accommodated are formed at intervals.

On the other hand, a hopper 15 for receiving a flat skewer is provided in front of the first set of chains 21. Hopper 15
Is a roller 16 and further a magnet roller 17. The respective shafts 16a, 17 of these two rollers
a is rotatably supported between the machine frames 2. Then, the first shaft 31 and the shaft 17a of the magnet roller, and similarly, the shaft 17a of the magnet roller and the shaft 16a of the roller are connected by a transmission chain 19. Thus, both rollers 16 and 17 rotate in the direction indicated by the arrow in FIG.

When the flat skewers 1 are thrown together into the hopper 15, the flat skewers slide down along the inclined bottom plate 15a of the hopper. The roller 16 has blades 16b around it. With the blades, the flat skewers that have slid down are picked up and sent to the magnet roller 17. The magnet roller 17 is provided with magnets 17b at regular intervals on its peripheral surface, and each magnet attracts the fed flat skewer 1 one by one.

The first pair of chains 21 hooks the flat skewer 1 attracted to the magnet roller 17 with the projection 7 to remove it from the magnet, and places the flat skewer 1 on the projection 7 and conveys it (right side in FIG. 4). Further, the chain 22 of the second set conveys the flat skewer 1 delivered from the chain 21 of the first set so as to be pushed by the projection 7 (left side in FIG. 4).

As shown in FIG. 5, the transported flat skewer 1 is moved on a third shaft 33 to a third set of chains 23.
(State A). When the third chain 23 comes up from below, the top 9 comes up in a falling state, but when the top sprocket 3 is turned, the top turns and the cradle 9a becomes horizontal. The flat skewer 1 is placed on the horizontal piece while being guided by the upper guide 11a of the frame 11 (state B). When the flat skewer 1 moves further downward in this way, it enters the frame 11 and descends (state C).

When the top 9 comes into contact with the flat skewers 1 stacked in the frame 11, the top 9 pivots upward,
The flat skewers 1 that have been loaded fall off the tops (D state) and are placed on the stacked flat skewers. The tops which have been lowered in this way go around the lower sprocket 3 and climb again.

Thus, the flat skewers 1 are successively stacked in the frame 11. On the other hand, the roller 12
Drops the lowermost flat skewer 1 into the groove 13 and transfers it to the next step.

[0016]

As described above, the device of the present invention is:
The top is pivotally supported on the link of the chain that moves in the vertical direction, and a flat bar that is carried on another chain is placed on the top of the top and carried down, and the top is placed on the stacked flat bars. When hit, the top jumps up and the flat bar falls from the top, and it is put on the stacked flat bars, and although it is a simple configuration, the stacking work of flat bars that has relied on human hands until now Can be automated.
