Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an automatic rice cake removal device in a round case, which is intended to mechanically and automatically take out a round rice cake housed in a round case and transport the round rice cake to a rice cake cutting machine. It is related to.

Conventionally, when producing rice cakes, a series of manufacturing methods have been known in which a rice cake is hardened and molded into a disk shape, cut into a tape shape from its outer periphery, and then cut vertically and horizontally to produce rice cake dough of a predetermined size. Although this process is carried out by a large number of companies, the work of taking out the round mochi from the round case currently relies mostly on manual labor.

However, since the round mochi is large and heavy, it requires hard labor for workers, and this work is not only avoided, but also an impediment to improving efficiency. The work involved in attaching this to the mochi cutting machine was wide-ranging, and there were many problems with full automation.

Especially regarding the method of removing the round mochi from the round case containing the mochi,
There is a proposal (for example, Japanese Patent Application Laid-Open No. 52-114079) that involves overturning the round case and applying pressure from the back side to push out the round mochi.
Apparatus for extracting the screw mold in the center (Japanese Unexamined Patent Publication No. 52-11 mentioned above)
407, the conventional example shown in Figure 1), and a device for removing steel plates and collecting round cases, but there is no proposal for a device for transporting stacked round cases containing mochi from the top one by one to a predetermined position. Not only is there no explanation given,
There was no explanation about the process of removing mochi when mochi grinding machines were used in parallel, and the entire book was insufficient to be applied to a fully automatic, high-efficiency production line.

However, this invention combines a transportation device for round mochi-filled cases with a mochi removing machine, and further combines a moving device, so that the stacked round cases of mochi are individually transported, the round mochis are pulled out, and the round mochis are further removed. They succeeded in fully automating the series of operations that transport the rice grains to the point where they are loaded onto the milling machine, improving the only heavy-duty work in the rice millet manufacturing process, and making it possible to improve the efficiency of preparing round rice cakes.

Conventionally, raw rice is steamed, and the rice cakes are dried by rolling or milling, then stored in round cases, and a lift is used to move and stack the round cases containing the rice cakes for cooling, hardening, and ripening. This solved the problem of heavy manual labor, but as mentioned above, the work of removing the round mochi from the round case after ripening still depended on manual labor.

However, it is known that a round mochi is provided with a straight screw hole in the center in order to fix it to the rotating shaft of a mochi cutting machine.
In order to create a screw hole, it is most common to bury a screw hole mold (a cylindrical mold with spiral stripes on the outer wall), and for mochi cutting machines, it is also considered to remove this screw hole mold. Must. Furthermore, round cases containing mochi are usually given in piles, but each time one piece is removed from the top, the height of the stack is reduced by one piece. Therefore, it is necessary to either move the round case onto a lift that constantly raises the top round case to a fixed position, or to make the lowering position of the gripping device that picks up the round case variable. I explained the latter. Next, embodiments of the present invention will be described based on the drawings.

First, on the leftmost side in Figures 1 and 2, round cases 1 containing rice cakes are stacked, and on the right side of the case 3 stands upright on the floor 2, and on the pillar 3 is a horizontally rotating arm village 4. is attached so that it can rotate horizontally, and a gripping device is installed on it to transport device A.

It is attached to pulleys 21, 22, and 23 coaxially attached to the pulleys 10, 12, and 13, and the other end is fixed to the center of the heavy keyboard 24.

Next, the rice cake removing machine B is used for branch villages 5 and 2, which are placed at a predetermined interval.
A support plate 26 is stretched horizontally in the middle of the support plate 5, and the tip side of the push-up pin 27 is exposed to the center of the support plate 26.
7 is rotatably mounted with iron on the upper end of a piston rod 29 of a fluid pressure cylinder 28 installed upright on the floor.

The push-up pin 27 has an entrance/exit hole 32 for a chicken stopper ball 31, 31a installed horizontally in the upper part of the hollow pin head 30, and the ball is connected to the inner flange 34 of the spiral shape 33 buried in the center of the round rice cake. It's free. A pin 35 for pushing out the sphere is housed in the center hole of the hollow pin head 30 so as to be able to move up and down, and the pin 35 is supported by a spring 36 (between the stepped portion of the pin 35 and the stepped portion of the central hole of the hollow pin head 30). A vent hole 37 is provided at the center of the upper end of the piston rod 29, and the hollow hole 39 of the air supply branch 38 fixed to the side wall of the piston rod 29 and the vent hole 37 are The hollow hole 39 is connected to an air supply hose 40. In addition, a stop tube 41 is fixed to the upper end of the piston rod.
1 is inserted into the lower end of the central hole of the hollow pin head 30 to form a pressurized space 42 between it and the lower end of the pin 35. The upper end of the connecting tube 43 is screwed to the lower end of the hollow pin head, and the receiving tube 44 is screwed to the lower end of the connecting tube 43, and the push-up pin 27 is constituted by the hollow pin head 30, the connecting tube 43, and the receiving tube 44. It has been done. In the rotary conveyance device C, one end of a horizontal annular frame 45 is fixed to the upper end of a supporting punch 5, the supporting punch 5 is rotatably attached to a bearing 46 on the floor, and a sprocket wheel 47 is fixed to the lower part of the supporting punch 5. , a chain 48 is attached to the sprocket wheel 47, and the chain 4

A support plate 55 is attached to the upper end of a piston rod 56 on the end side of the conveyor 6, and the lower end of the piston rod 56 is inserted into a fluid pressure cylinder 57 installed on the floor, so that it can be raised and lowered by a guide shaft 58 without rotating. It has become.

This support plate 55 is for receiving the round rice cake in the horizontal annular frame 45 and transferring it onto the conveyor 6 when it is released from the pressing piece.
This is not an essential device, as it only needs to be transferred upwards smoothly and without impact. On the right side of the conveyor 6 (in FIG. 1),
A round rice cake converting device D as shown in FIG. 13 is provided.

The conversion device D has the lower wall of the round rice cake receiving plate 59 bent at one end (the left end in FIG.
A fluid pressure cylinder 62 and a piston rod 63 for the shock receiver are attached to one side of the lower wall. In the figure, 64 is a guide roller, 65 is a stopper, 66 is a stopper operating handle,
67 is a switching handle. Next, regarding the above example,
Let's explain its operation.

First, in FIGS. 1 to 6, when the piston rod 9 is retracted in the direction of arrow 68 in FIG. The wire-11,1 is pulled in the direction indicated by 69.
The support plate 14 fixed to the left end of 1a rises to the position shown in the fourth figure. In this case, since the heavy keyboard 24 is at the position indicated by the chain line 24a in FIG. 4, the grasping claw 16 is also at the position indicated by the chain line 16a in the figure. When the motor 70 is switched on, it rotates the sprocket wheel 71 fixed to its output shaft via the speed reducer. 74 (for example, as indicated by the arrow 75 in FIG. 2), the gripping device is opposed to the round case 1. Therefore, when the piston rod 9 is moved in the direction of the arrow 76,
As the pulley 10 also moves in the same direction, the chains 11 and 11a move in the direction of arrow 77 in FIG. 6, and the support plate 14 descends and comes into contact with the top round case. When the support plate comes into contact with the round case, the wires 11 and 11a are loosened, and the receiving arm 78 of the pulley 13 rotates in the direction of arrow 80 about the horizontal axis 79. The receiving arm 78 in the above is supported in a cantilever manner by a horizontal shaft 79 on the horizontal rotating arm village 4, and a projecting piece 81 is provided protruding from the tip side of the receiving arm 78, and a receiving shaft is inserted into the through hole 82 of the projecting piece 81. 83 is inserted,
The protruding piece 81 is constantly subjected to upward pressure by a spring 86 between the lower gold plate 84 of the holder 83 and the seat 85 of the protruding piece 81 . Therefore, when the downward force applied to the pulley 13 is relieved, the receiving arm 78 is pushed up by the spring 86 and rotates as described above. When the protruding piece 81 rises, it comes into contact with the protruding piece 88 of the microswitch 87.
When the circuit of the microswitch is closed, the spin rod 19 (Figs. 4 and 6) is pulled in the direction of arrow 89 according to the command, and the wire 20 is also pulled in the same direction, and one end of the wire 20 is pulled. The heavy keyboard 24 fixed to is pulled up from the position 24a shown by the chain line in FIG. 4 to the position 24 shown by the solid line. When the heavy keyboard is pulled up in this way, the force that was pressing down on the base end of the gripping claw 16 is released, so the gripping claw 16 rotates inward around the horizontal axis 17, and its tip end claw 16b will be caught on the collar la of the round case 1.
Then, the piston rod 9 is retracted in the direction of the arrow 68 and the wires 11, 11a are pulled in the direction of the arrow 69, thereby raising the gripping device that grips the round case 1 (as shown by the solid line in FIG. 4). Next, the motor 70 is started, the pipe ball 73 is rotated via the sprocket wheels 71, 74, and the chain 72, and the horizontal rotary arm punch 4 is rotated in the direction of the arrow 75, and the round case containing the mochi is placed above the mochi removing machine. Move to. In this case, the rotation direction of the horizontal rotating arms does not necessarily have to be in the direction of arrow 75, and may be in the opposite direction, but when it is in the opposite direction, it is a stack of empty round cases (la in Fig. 2).
) should be kept out of the way. In the case of one-way rotation as shown in Figure 2, the round cases containing mochi are carried by the gripping claws from the loading position onto the mochi removing machine, after the mochi is extracted, only the round cases are carried to the round case stacking position, and then the round cases are grasped. By returning only the claw to the loading position of the round case filled with mochi, the gripping claw rotates once, but if the worker carries the empty round case by hand, the gripping claw will not be able to load the round case containing mochi. It is also possible to reciprocate between the position and the mochi removing machine. When the round case is directly above the mochi removing machine, raise the piston rod 9 in the direction of arrow 76 and move the pulley 10
When also raised in the same direction, the chain 11 moves in the direction of arrow 77 (in FIG. 6), so that the round case is lowered and placed on the support plate 26 of the mochi removing machine B. When the round case is placed on the support plate 26, the wires 11 and 1 are connected as before.
1a becomes loose, the arm punch 78 rotates in the direction of the arrow 80, and the receiving piece 81 pressurizes the protruding piece 88 of the microswitch 87, so the command generated by closing that circuit causes the piston rod 19 to move as shown in FIG. As it moves to the left and loosens the wire 20, the heavy keyboard 24 fixed to one end of the wire is lowered, thereby pressing down on the base end of the grip claw 16. Therefore, the gripping pawl 16 rotates outward about the horizontal axis 17 and opens the pawl portion 16b, so that the pawl portion is removed from the flange of the round case. When the piston rod 9 is lowered in this state, the pulley 10 is also lowered, and the wires 11 and 11a are pulled in the direction of arrow 69, thereby pulling up the gripping device. Next, if the piston rod 51 of the fluid pressure cylinder 49 is pulled in the direction of arrow 89 in FIG. 1 in the direction of (arrow 90 in Figure 2)
Rotate 80 degrees and overlap directly above the round case.

Then, when the piston rod 29 is raised as shown by the arrow 91, the step part of the push-up pin 27 and the inner metal part 34 are stopped, and the round rice cake 7 is pushed up out of the case. In this case, since the horizontal annular frame 45 faces the round case, there is no risk that the round rice cake and the round case will rise together. When the round rice cake is pushed up in this way and enters the horizontal annular frame 45, the piston rods of the fluid pressure cylinders 53, 53a, 53b are pushed out, and the pressing pieces 54, 54a, 54b press the round rice cake from the outer periphery. Then, the pin 35 of the push-up pin 27 attached to the piston rod 29 is raised.

This pin 35 is pushed up by pressurized air blown up as shown by arrow 92 from the vent hole 37 in the piston rod 29. When the pin 35 rises, the latching spheres 31, 31a, which are in the entrance/exit hole 32 of the hollow pin head 30, are moved to the tenth position.
Push it out as shown by the solid line in the figure and engage it with the inner flange 34. Therefore, when the piston rod 29 is lowered as shown by the arrow 93, the spiral shape 33
descend together. In this case, the spiral mold 33 will rotate and come off, and the push-up pin will also rotate.
However, if the spiral mold 33 comes into contact with the bottom plate of the round case,
By removing the air in the vent hole 37 of the piston rod 29, the pin 35 is lowered by the spring 36, and the latching balls 31, 31a are retracted into the entrance/exit hole, and the latching is released, so that the spiral type is a round case. It stops inward, and the push-up pin separates downward together with the piston rod. Next, when the piston rod 52 of the fluid pressure cylinder 50 is pulled in the direction of the arrow 94, the branch punch 5 rotates, and the horizontal annular frame 45 moves to the third position.
It rotates from the position shown by the chain line in the figure to the position shown by the solid line. Therefore, when the piston rod 56 of the fluid pressure cylinder 57 is raised as shown by the arrow 95 (shown by the chain line in FIG. 3) and the pressing pieces 54, 54a, and 54b of the horizontal annular frame 45 are loosened, the round rice cake is moved from the support plate by its own weight. It descends upwards and is supported.
Then, when the piston rod 56 is lowered as shown by the arrow 96, the round rice cakes remain on the conveyor 6. Conveyor 6 is a forcibly driven roller conveyor (for example, one side of the rollers is forcibly driven)
Alternatively, a chain conveyor may be used, but by driving this, the round rice cake moves as indicated by the arrow 97, and when it comes to the installation part of the converting device ○, it is stopped by the stopper 65. Therefore, by operating the switching handle 67 (or by detecting that the round rice cake has come into contact with the stopper), pressurized fluid (for example, pressurized air) is sent to the lower part of the fluid pressure cylinder 98 to move the piston rod 61 in the arrow direction. When the rice cake receiving plate 59 is raised as shown in the arrow 99, the round rice cake receiving plate 59 rotates as shown by the arrow 100 (with the rice cake placed thereon) around the horizontal axis 69, and finally the round rice cake receiving plate 59 stands upright.
Therefore, the round mochi also stands upright. In this case, the piston rod 63
The fluid pressure cylinder 62 acts as a cushioning material when the round rice cake stands upright, and can prevent excessive rocking. Next, send the round mochi in the direction of the display 101, and if necessary, after installing the round mochi on the shaft of the mochi cutting machine E, lower the piston rod 61 as shown by the arrow 102, and the round mochi receiving plate returns to the old position. Return. In the above, when the stopper operating handle 66 is operated and the stopper 65 is lifted, the round mochi passes through this area and stops at the next stopper, and the mochi is sent upright to the mochi cutting machine in the same manner as above. . In the embodiment, the switching handle 67
For example, the passage of the round mochi can be detected mechanically or optically, and the stopper can be opened and closed alternately to feed the mochi evenly and alternately to the two mochi grinders. It may also be configured as Similarly, if two or more mochi cutting machines are installed in parallel, converters corresponding to the number of mochi cutting machines may be installed along the conveyor. That is, according to the present invention, since the conveying device and the mochi removing machine are combined, the series of operations of removing the round mochi from the round case and supplying it to the mochi cutting machine, which was the most labor-intensive task in the confectionery dough production line, is eliminated. has been fully automated, freeing workers from heavy labor, and has significantly improved production efficiency, such as by making it possible to supply round mochi from multiple mochi milling machines at the same time. This has the effect of preventing damage to both the case and the case. In addition, since a moving device is combined with the scale remover, it is possible to remove rice cakes from the scale remover.
Also, the transfer to the conveyor is extremely smooth, and there is no risk of impact on the round rice cakes, so there is an effect that there is no damage to the round rice cakes.

Furthermore, by attaching a converting device to the conveyor, the horizontally conveyed round rice cakes can be turned vertically to facilitate mounting on the rice cake cutting machine. In addition, in the mochi removal machine, by raising and lowering the push-up pin, it is possible to smoothly take out the round mochi and remove the spiral mold, and the spiral mold is set in its original position in the round case. Therefore, the round case does not require any effort to reuse, and it has an integral part that is currently in use, or has a removable bottom. There are also effects that can be applied to round cases.
