Abstract

PURPOSE:To make it possible to cut a cake or the like smoothly while preventing the attachment of cream and the like to the edge body, by providing an oscillation device to give an ultrasonic oscillation to the edge body, and a swaying device to sway the edge body in the horizontal direction. CONSTITUTION:While an ultrasonic oscillation is applied to an edge body 50 by an oscillation device 48, the edge body 50 is swayed in the horizontal direction by a swaying device 41. As a result, an energy is given to a cake on a holding table 9 locally, and the cake or the like is cut smoothly while preventing the attachment of read or cream to the edge body 50. Then, after the cutting, the edge body 50 is pulled out horizontally by a pulling-out device (rodless cylinder) 35, and the cut end once cut off is prevented from rubbed again by the edge body 50. Consequently, the cut end of the cake can be finished smooth, and the moving time of the edge body 50 can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cutting device for cakes, sandwiches, etc. that efficiently cuts cakes, sandwiches, etc. with smooth and hygienic cuts.

[Prior Art] For example, when cutting a circular torte into fan-shaped cakes with the same center angle, such cakes are usually soft and
Since it easily adheres to the blade, it is difficult to cut smoothly and to finish the cut end smoothly. As shown in FIG. 11, a cutting device used for this purpose includes a holding table 71 on which the torte is placed, a blade 72 installed above the holding table 71, and a rotating holding table 7K. A device is used which is equipped with a drive mechanism for positioning the device and moving it up and down. This blade body 72 is an endless blade body like a scroll saw, and is wound around a pair of pulleys 73 to be driven. Such a device includes a blade 72
A wiping device 74 that clamps the blade 72 is provided to remove cake chips and the like adhering to the blade.

[Problems to be Solved by the Invention] In the conventional technology as described above, since the blade 72 is endless, the blade 72 is pulled back again along the cut end of the cake after cutting the cake. There is a need. As a result, the cut end becomes 21 degrees and becomes unsmooth, which impairs the aesthetic appearance and reduces the product value.Also, the cake moves or falls when being pulled out, making it difficult to perform the cutting operation smoothly. There were problems such as a decrease in work efficiency due to the time it took to pull back the 72. In addition, in the case of the endless blade body 72 as described above, the wiping device 74 must be kept between the legs at all times, so there is no opportunity to clean the wiping device 74 itself, and there is no chance of cleaning the wiping device 74 itself. There were problems such as chips adhering to the pulley 73 and staining the blade body 72 again, making it difficult to maintain the blade body 72 in a clean state.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a holder on which a cake, etc. is placed, and a holder placed above the holder almost parallel to the top surface of the holder. A blade body facing the blade body, a vibration device that applies ultrasonic vibration to the blade body, a rocking device that causes the blade body to swing in the horizontal direction, and a holding base that moves relative to the blade body. This configuration includes a moving device for cutting the blade, and a pulling device for moving the blade in the direction along the blade after cutting. This device may be provided with a clamping member that can be opened and closed to clamp the blade and wipe the blade when pulled out after cutting a cake or the like, and a water cleaning mechanism may be attached to the clamping member.

[Function] In such a device for cutting cakes, etc., by applying ultrasonic vibration and rocking to the blade, energy is locally applied to the cake, and bread and cream can be cut without 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. This eliminates the need to scrape the cut end again, provides a smooth finish to the cut, and The time it takes to move the blade is also reduced.

Furthermore, by pinching the blade body subjected to ultrasonic vibration with the wiping member when the blade is pulled out, the blade body is completely cleaned at the same time as the blade body is pulled out. Therefore, since the wiping member is not restrained during cutting, the wiping member is cleaned by passing water through it once during cutting.

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

First, the cake table 16 on which the torte is placed is the one that is not in the cutting position! Put it on 4. The table 14 is positioned and prevented from rotating by fitting the positioning pin 15 of the support member 8 into the recess 15b of the annular member 15a on the lower surface thereof. Next, when the rotary actuator 4 is operated to rotate the rotary shaft 5 until the locking plate 19 abuts the stopper 20, the table knife 4 comes under the blade 50. At this time, the cake stand! One of the grooves 17 of 6 is the blade body 50
” so that the pin hole 18 of the inner f!i13 is at the position of the drive pin 31 of the holding table drive device
A table 14 is positioned relative to the support member 8.

In the cutting mechanism B, the rodless cylinder 35 is actuated, and the support frame 37 is advanced toward the insertion hole 5' side, and the blade body 5 is
It makes 0 stand out. When the drive motor 42 of the swinging device 41 is started, this rotation is transmitted to the disc 44 via the belt 43, and swings the movable piece attached to the connecting rod pivoted to the eccentric bin 45 from side to side. do. Therefore, the blade portion 40 is swung left and right along the blade body 50, and ultrasonic vibrations are applied by the ultrasonic generator 48. At this point, the holding table driving device 21 is activated.

That is, first, when the sub cylinder 28 operates and lifts the fixed plate 27, the main cylinder 25 and the main shaft 23 rise together, and the drive pin 31 moves into the bottle hole! Insert into 8. 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 is 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 lifts the main shaft 23 further upwards.
This causes the blade 50 to come into contact with the cake and cut the cake. At this time, since the blade 5'O 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 added action prevents the adhesion of bread, cream, etc. to the blade body 50. Since the blade body 50 is supported by the blade holding rollers 52 and 53 on the top and side surfaces, 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, and the blade 50 is pulled out from the cake. (stop rocking if necessary). Immediately before pulling out, the air cylinder of the wiping device 55 is activated, and the wiping member 57 and the remover 59 sandwich the blade 50 from both sides. As a result, bread crumbs, cream, etc. that adhere 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 purified. At this time, the atrophic plate 59 is not in close contact with the blade body 50, but is set to have a predetermined gap, and removes relatively large pieces of bread attached to the blade body 5'. The removal member 57 is in close contact with the blade 50 and removes cream etc. adhering to the blade 50. When the blade 50 is pulled out, the ultrasonic vibration is applied as it is, thereby wiping off the cream etc. that are difficult to remove. It is wiped cleanly by the member 57. After the blade 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 holding table drive device 2M is activated. The rotation is transmitted to the main shaft 23 via the gear box 29, and this rotation is further transmitted to the table 14 via the engagement member 32, the drive pin 31, and the inner cylinder 13 to rotate the table 14 by a predetermined angle.Table 14 is lowered, the rodless cylinder 35 is activated, the support frame 37 is moved toward the cake, and the blade 50 is again in the cutting position.In this state, the main cylinder 2
5 is extended again, the table 14 and the cake are moved upward, and the cake is cut. By repeating this a predetermined number of times (half the number of cake divisions),
Cake cutting is complete. When cutting is completed, the blade 50
is pulled out and the table! 4 is further rotated by a predetermined angle while descending, and returns to its original position relative to the support member 8. Then, the sub cylinder 28 contracts, and the positioning pin is attached to the annular member 15a! 5 is inserted, the table 14 is positioned with respect to the support m member 8, and furthermore, the drive pin 3I of the engagement member 32 and the pin hole 18 of the inner cylinder 13 are disengaged. Therefore, the rotary actuator 4 is operated in the opposite direction from the previous time,
The table 4 on which the cut cake is placed is the cutting part zt
, and another table 14 comes to the cutting position. A cake stand 16 on which a new cake is placed is placed on the table 14, and this cake is then cut. Meanwhile, the cut cake is taken down from the table turtle 4 and headed for the process of being divided and rubbed, and a new cake stand I6 is placed on the empty table 14! be done.

To change the number of divisions of K and K, operate the lever 33 to change the engagement in the gearbox 29, change the reduction ratio, and change the ratio of the rotation of the main shaft 23 to the rotation of the induction motor 30. It is done.

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

[Effects of the Invention] As described in detail above, the present invention includes a holding table on which a cake or the like is placed, a blade facing above the holding table substantially parallel to the upper surface of the holding table, A vibration device that applies ultrasonic vibration to the blade body, a swing device that makes the blade swing in the horizontal direction, a moving device that moves the holding base relatively to the blade body, and a blade body after cutting. The structure is equipped with a pulling device that moves in the direction along the blade, so by applying ultrasonic vibration and rocking to the blade, it can smoothly remove cakes, etc. while preventing cream from getting onto the blade. By cutting and pulling out the blade horizontally after cutting, there is no need to scrape the cut end again, the cut end is finished smoothly, and the time required for moving the blade is shortened. In addition, by sandwiching the blade, which is subjected to ultrasonic vibrations when it is pulled out, with a wiping member, the blade is completely cleaned at the same time as it is pulled out, making it possible to perform sanitary work. It is something that you have.
