[Problems to be Solved by the Invention] In the conventional technology as described above, the blade body 72
Since it is endless, it is necessary to once cut the cake and then pull back the blade 72 along the cut end of the cake. As a result, the cut end is rubbed and becomes unsmooth, which impairs the aesthetic appearance and reduces the product value.Also, when pulling out the cake, the cake moves or falls over, making it difficult to perform the cutting operation smoothly. There were problems such as a drop in work efficiency during the time it took to pull back. Also,
In the case of the endless blade 72 as described above, the wiping device 74 must be always clamped, so
There are problems such as there is no opportunity to clean the wiping device 74 itself, and chips attached to the blade body 72 adhere to the pulley 73 and contaminate the blade body 72 again, so it is difficult to maintain the blade body 72 in a clean state. It was difficult.

[Means for Solving the Problems] The present invention includes a holding table on which a cake or the like is placed, a blade disposed above the holding table and facing substantially parallel to the upper surface of the holding table, and a blade body disposed on the holding table. A vibrating device that applies ultrasonic vibration, a reciprocating device that moves the blade back and forth in the horizontal direction, a moving device that moves the holding base relative to the blade, and a vibration device that is connected to one end of the blade. The present invention is characterized in that it includes a pulling device that pulls out the other end of the blade from the cake or the like by moving the blade in the horizontal direction after cutting.

Further, the invention according to claim 2 further includes a wiping device that wipes off chips such as cake by sandwiching the blade body in the process of being pulled out using a wiping material that is moved near and far from both sides of the blade body. It is characterized by

[Function] In such a device for cutting cakes, etc., energy is locally applied to the cake by applying ultrasonic vibration and reciprocating movement to the blade, thereby preventing bread and cream from sticking to the blade. , cakes, etc. can be cut smoothly. The blade only needs to be gripped at one end, and the pulling device can be activated to pull out the blade horizontally after cutting, so there is no need to scrape the cut once again, the cut is finished smoothly, and The time it takes to move the blade is also reduced. Furthermore, in the invention described in item 2, by sandwiching the blade between the wiping members of the wiping device when pulling out the blade, the blade can be cleaned at the same time as the blade is being pulled out. If ultrasonic vibration is applied, the blade will be completely cleaned even if it is hard to remove, such as cream. Furthermore, this wiping device only needs to be used when pulling out the blade, and by leaving it open during cutting and releasing the restriction from the blade, cleaning can be performed during that time.

The removal plate 59 has an elongated hole 60 so that its mounting position can be adjusted. Blade body 5
0 is disposed between both fixing members 56, and when both fixing members 56 are closed by the air cylinder, a wiping member 57 is used to remove the wiping member 57 as shown in FIGS. The blade body 50 is designed to be pinched. A water tank 61 is installed on the top of the cover 34 of the cutting mechanism B, a water supply pipe 62 is connected to the bottom of the water tank 61, and the other end of the water supply pipe 62 is provided above the fixing member 56. The wiping member 57 and the removal plate 59 of the wiping device 55 are fitted with the water supply hole 65 so that water falls onto the wiping member 57 and the removal plate 59 for cleaning. Further, a funnel-shaped water receiver 63 is installed below the wiping device 55.

The operation of the device for cutting cakes, etc. configured as described above will be described below.

First, the cake stand 16 on which the torte is placed is placed on the table 14 that is not at the cutting position. The table 14 has a recess 15b in an annular member 15a on its lower surface.
The positioning pin 15 of the support member 8 is inserted into the support member 8, thereby positioning the support member 8 and preventing it from rotating. Next, the rotary actuator 4 operates to rotate the rotary shaft 5 until the locking plate 19 comes into contact with the stopper 20, and the table 14 comes under the blade 50. At this time, the table 14 is moved so that one of the grooves 17 of the cake stand 16 is parallel to the blade 50 and the pin hole 18 of the inner cylinder 13 is at the position of the drive pin 31 of the holding stand drive device 21. It is positioned relative to the support member 8.

In the cutting mechanism B, the rodless cylinder 35
is actuated to advance the support frame 37 toward the insertion hole 51 in advance to make the blade 50 protrude. When the drive motor 42 of the reciprocating device 41 is started,
This rotation is transmitted to the disk 44 via the belt 43, causing the movable section attached to the connecting rod pivotally connected to the eccentric pin 45 to reciprocate from side to side. Therefore, the blade portion 40 is reciprocated from side to side along the blade body 50, and ultrasonic vibrations are applied by the ultrasonic generator 48. Here, the holding table driving device 2
1 is activated. That is, first, when the sub cylinder 28 operates and lifts the fixed plate 27, the main cylinder 25 and main shaft 23 rise together, and the drive pin 31
fits into the pin hole 18. Further, the upper surface of the engaging member 32 comes into contact with the lower surface of the inner cylinder 13, and the inner cylinder 13 and the table 14 are connected to the annular member 15a and the positioning pin 15.
lift until it disengages. In this state, the cake and the blade 50 are not yet in contact. Next, the main cylinder 25 is extended and the main shaft 23 is further lifted upward, so that the blade 50 comes into contact with the cake and cuts the cake. At this time, since the blade body 50 is vibrating ultrasonically, a large amount of energy is intensively applied to the cutting part of the cake, and the cake is cut with good sharpness.
The effect of the reciprocating movement of 0 is added to prevent bread, cream, etc. from adhering to the blade body 50. Since the blade body 50 is supported on the top and side surfaces by the blade holding rollers 52 and 53, the blade body 50 is prevented from bending or twisting regardless of the cutting resistance received from the cake. When the blade 50 reaches the groove 17 of the cake stand 16, the main cylinder 25 stops, and the rodless cylinder 35 operates to move the support frame 37 away from the cake.
0 is pulled out of the cake (stopping the round trip if necessary at this time). Immediately before pulling out, the air cylinder of the wiping device 55 is activated, and the wiping member 57 and removal plate 59 sandwich the blade 50 from both sides. As a result, bread crumbs, cream, etc. adhering to the blade body 50 when the blade body 50 is pulled out from the cake are wiped off by these members, and the blade body 50 is cleaned. At this time, the removal plate 59
The wiping member 57 is set to have a predetermined gap and is not in close contact with the blade body 50, and removes relatively large bread crumbs etc. attached to the blade body 50.
The cream and the like that have adhered to the blade body 50 are removed. When the blade body 50 is pulled out, the ultrasonic vibrations are applied as they are, and as a result, cream and the like that are difficult to remove are thoroughly wiped off by the wiping member 57. After the blade body 50 is pulled out, the main cylinder 25 contracts and the main shaft 23 and table 14 descend, and at the same time, the induction motor 30 of the holder drive device 21 operates, and the rotation of the induction motor 30 causes the gearbox 29 to rotate. This rotation is transmitted to the main shaft 23 via the engagement member 3.
2, the table 1 via the drive pin 31 and the inner cylinder 13
4, and rotates the table 14 by a predetermined angle. When the table 14 is lowered, the rodless cylinder 35 is activated, the support frame 37 is moved toward the cake, and the blade 50 is brought to the cutting position again. In this state, the main cylinder 25 is extended again, and the table 14
and the cake is moved upwards and cutting of the cake is performed. By sequentially repeating this for a predetermined number of rotations (half the number of cake divisions), the cake cutting is completed. When the cutting is completed, the blade 50 is pulled out, and the table 14 is lowered and further rotated by a predetermined angle to return to its original position relative to the support member 8. Then, the sub cylinder 28 contracts, and the annular member 1
The positioning pin 15 is inserted into the table 14.
is positioned with respect to the support member 8, and the drive pin 31 of the engagement member 32 and the pin hole 18 of the inner cylinder 13
is disengaged. The rotary actuator 4 is then actuated in the opposite direction to the previous one, the table 14 on which the cut cake is placed is moved from the cutting position, and the other table 14 comes to the cutting position. A cake stand 16 on which a new cake is placed is placed on this table 14, and this cake is then cut. On the other hand, the cut cake is taken down from the table 14 and headed for the process of being divided and wrapped, and a new cake stand 16 is placed on the empty table 14.

To change the number of cake divisions, operate the lever 33 to change the engagement in the gearbox 29, change the reduction ratio, and
This is done by changing the ratio of the rotation of the main shaft 23 to the zero rotation.

Water in the water tank 61 is supplied to the wiping device 55 through the water supply pipe 62, and the wiping member 57 and removal plate 59
It washes away the deposits on the surface of the water and flows into the water receiver 63.

[Effects of the Invention] As detailed above, according to the present invention, by applying ultrasonic vibration and reciprocating movement to the blade pair,
It cuts cakes, etc. smoothly while preventing cream etc. from adhering to the blade, and by pulling out the blade horizontally after cutting, there is no need to rub the cut end again. The time it takes to move the body is also reduced. Further, according to the second aspect of the invention, by pinching the blade between the wiping members of the wiping device when pulling out the blade, the blade can be cleaned at the same time as the blade is being pulled out. By applying ultrasonic vibrations to the body, even items that are difficult to remove can be completely cleaned, making it possible to perform sanitary work. Furthermore, this wiping device only needs to be used when pulling out the blade, and by leaving it open during cutting and releasing the restraint from the blade, it is also possible to clean it during that time.
