In addition, casters 16 are attached to the lower portions of both ends of the lower width girder 15, respectively, so that the transport type automatic cutting device 1 can easily move the casters 16 for use.
[0044]
Next, the operation based on the configuration of the embodiment of the present invention will be described below.
For example, when cutting the boiled egg a whose shell has been peeled as an object to be cut using the transport-type automatic cutting device 1, a large number of boiled eggs a whose shell has been peeled are put into the supply container 11. And the motor 4 is driven.
[0045]
When the motor 4 is driven, the driving force of the motor 4 is transmitted to the first intermittent cam mechanism 5 and the second intermittent cam mechanism 6 through the rotary shaft 41, the rotary piece 42, the connecting rod 43, and the rotary support piece 44. The first intermittent cam mechanism 5 and the second intermittent cam mechanism 6 are set such that the intermittent interlocking connection state is directly opposite.
[0046]
That is, when the first one-way cam 51 of the first intermittent cam mechanism 5 is in an interlocking connection state with the motor 4, the second one-way cam 61 of the second intermittent cam mechanism 6 is in a non-interlocking connection state with the motor 4, When the first one-way cam 51 of the first intermittent cam mechanism 5 is in the non-interlocking connection state with the motor 4, the second one-way cam 61 of the second intermittent cam mechanism 6 is in the interlocking connection state with the motor 4.
[0047]
When the motor 4 and the first intermittent cam mechanism 5 are in the interlocking connection state, while the rotation shaft 41 of the motor 4 makes a half rotation, the engagement pin 52 a of the first operating piece 52 is engaged with the engagement groove of the first one-way cam 51. The engagement pin 52a rotates the first one-way cam 51 clockwise by 90 degrees in a state of being engaged with one of the first cams 51a.
[0048]
When the first one-way cam 51 rotates clockwise by 90 degrees, the rotation transmission shaft 51b having one end connected to the center of the first one-way cam 51 also rotates clockwise by 90 degrees, and the other end of the rotation transmission shaft 51b is connected. The driven pulley 54 also rotates 90 degrees in the same direction, and the driven pulley 55, which is linked to the drive pulley 54 via the endless belt 54a, also rotates in the same direction by an angle.
[0049]
When the driven pulley 55 rotates, the conveyor rotation transmission shaft 55a, one end of which is connected to the center of rotation of the driven pulley 55, also integrally rotates by the same angle. The other end of the conveyor rotation transmission shaft 55a is linked to the left and right driving sprockets 21 via the driving bevel gear 55b, the driven bevel gear 55c, and the conveyor driving shaft 55d, so that the left and right driving sprockets 21 also rotate. In this case, since the drive bevel gear 55b has a higher gear ratio than the driven bevel gear 55c, the conveyor drive shaft 55d rotates 90 degrees n times the conveyor rotation transmission shaft 55a by n times. One end of an endless chain 23 is wound around each of the left and right drive sprockets 21, and the rotation of the drive sprocket 21 causes the upper endless chain 23 to move from the start end 2 a toward the end 2 b.
[0050]
A concave curved peripheral surface rotating roller 24 is rotatably connected at predetermined intervals between the moving left and right endless chains 23, and the lower surface of the concave curved peripheral surface rotating roller 24 is an upper surface of the traveling path 25. , Each concave curved side surface type rotation roller 24 moving toward the terminal end side 2b moves while rotating.
[0051]
When the conveyor 2 is operated, the boiled eggs a, whose shells in the supply container 11 have been peeled off, are discharged one by one onto the concave curved peripheral rotary roller 24 on the starting end side 2a in an irregularly oriented state. On the top. Each boiled egg a placed in an irregular orientation on the concave curved side peripheral type rotating roller 24 is gradually aligned sideways by the rotation of each concave curved side peripheral type rotating roller 24. It will move toward the terminal side 2b.
[0052]
On the other hand, during the half rotation of the motor 4, in the second one-way cam 61 of the second intermittent cam mechanism 6, the engagement pin 62 a engaged with the engagement groove 61 a of the second one-way cam 61 rotates counterclockwise. Although it rotates and comes out of the engagement groove 61a, the engagement pin 62a that rotates counterclockwise and the second one-way cam 61 are not in an engagement relationship, so the second one-way cam 61 does not rotate during this time. Therefore, the driving force of the motor 4 is not transmitted to the cutter 3 through the second intermittent cam mechanism 6, and the cutter 3 is in a stopped state. That is, when the conveyor 2 is in the operating state, the cutter 3 is stopped.
[0053]
When the motor 4 further rotates half a turn from the half-rotation state, during the half rotation, the engaging pin 62a of the second operating piece 62 is inserted into the engaging groove 61a of the second one-way cam 61 of the second intermittent cam mechanism 6. When engaged, the engagement pin 62a rotates the second one-way cam 61 clockwise by 90 degrees.
[0054]
When the second one-way cam 61 rotates clockwise by 90 degrees, the rotation transmission shaft 61b having one end connected to the center of the second one-way cam 61 also rotates clockwise by 90 degrees, and the other end of the rotation transmission shaft 61b is connected. The driven spur gear 64 also rotates 90 degrees in the same direction, and the driven spur gear 65 meshing with the drive spur gear 64 rotates n times 90 degrees depending on the gear ratio.
[0055]
When the driven spur gear 65 rotates, the cutter rotation transmission shaft 65a, one end of which is connected to the rotation center of the driven spur gear 65, integrally rotates by the same angle. Since the other end of the cutting device rotation transmission shaft 65a is connected to the drive unit of the cutting device 3, the distal end side of the arm 31 of the cutting device 3 rotates downward from above the conveyor 2.
[0056]
A cutting blade 32 is provided on each of the left and right sides on the tip side of the rotating arm 31. The cutting blade 32 that rotates downward halves a boiled egg a as an object to be cut placed on the conveyor 2. Disconnect. The cutting blade 32 that has cut the boiled egg a returns above the conveyor 2 by the upward rotation of the arm 31.
[0057]
On the other hand, during the further rotation of the motor 4 by half, in the first one-way cam 51 of the first intermittent cam mechanism 5, the engagement pin 52a engaged with the engagement groove 51a of the first one-way cam 51 is rotated counterclockwise. The first one-way cam 51 does not rotate during this time because the engagement pin 52a that rotates counterclockwise and the first one-way cam 51 are not engaged. Therefore, the driving force of the motor 4 is not transmitted to the conveyor 2 through the first intermittent cam mechanism 5, and the conveyor 2 is in a stopped state. That is, when the cutting blade 32 is in the operating state, the conveyor 2 is stopped.
[0058]
Thereafter, each time the motor 4 makes a half turn, the above operation is performed alternately and repeatedly, and the boiled egg a to be cut is cut in half, and the boiled egg a cut in half is transferred to the conveyor 2. From the terminal side 2b of the container.

A first intermittent cam mechanism for intermittently interlocking connection is provided, and the drive unit of the cutter for cutting the object to be cut being conveyed by the conveyor and the motor are intermittently interlockingly connected alternately to an interlocking connection state and a non-interlocking connection state. A second intermittent cam mechanism is provided, and the intermittent interlocking connection state of the first intermittent cam mechanism and the second intermittent cam mechanism is reversed, the cutter is stopped when the conveyor is driven, and the cutter is driven when the conveyor is stopped. By cutting the above cutting object, it is possible to control both the driving of the conveyor and the driving of the cutter with one motor, and it is possible to avoid that the structure becomes complicated, Since at the time of driving the duck cutter conveyor is stopped, it is possible to reliably cut the object of cutting in the conveying in the conveyor, and may carry a cutting object after cutting by the conveyor.
[0061]
In addition, according to the transport type automatic cutting device according to the second aspect of the present invention, both ends are rotatably supported by the pair of endless chains, and the concave curved side peripheral surface type rotation is arranged at predetermined intervals in the circulation direction of the endless chains. A first intermittent cam mechanism for intermittently and interlockingly connecting a motor and a drive unit of a conveyor that conveys a boiled egg with the shell of the object to be cut removed between rollers between an interlocking connection state and a non-interlocking connection state. And a second intermittent cam mechanism that intermittently interlocks and connects the drive unit of the cutter and the motor that intermittently and interlockingly alternately to an interlocking connection state and a non-interlocking connection state to cut the boiled egg of the object to be cut being conveyed by the conveyor. In addition, the intermittent interlocking connection state of the first intermittent cam mechanism and the second intermittent cam mechanism is reversed, the cutter is stopped when the conveyor is driven, and the cutter is driven when the conveyor is stopped, so that the object to be cut on the conveyor is stopped. Boiled egg By cutting, both the drive of the conveyor and the drive of the cutter can be controlled by one motor, and the structure can be prevented from becoming complicated.Moreover, the conveyor stops when the cutter is driven. Therefore, the boiled egg of the object to be cut that is being conveyed on the conveyor can be reliably cut, and the boiled egg after cutting can be conveyed by the conveyor. Furthermore, by rotating the concave side peripheral surface type rotating roller at the time of movement, the boiled eggs placed irregularly on the concave side peripheral surface type rotary roller are aligned sideways during the movement, and the cutting device is used. Can be cut.
