Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a guide device for guiding an object to be cut, such as bread, to a cutting position.

[Conventional technology]

A conventional guide device for transporting bread to a cutting position for cutting bread to a predetermined thickness with a cutting blade has a structure in which four guide plates are individually arranged on the upper and lower sides and on the left and right sides.

[Problem that the invention attempts to solve]

With the structure of the conventional guide device described above, if the size or thickness of the bread changes, it is necessary to readjust the mutual relationship between the four guide plates and the five members of the cutting blade to a predetermined state, and the cutting blade , or when replacing the turret, etc., the entire tool must be disassembled, which is troublesome and takes time and effort.

[Means for solving problems]

In the present invention, a plurality of insertion grooves for cutting blades are formed on two mutually opposing surfaces in parallel with each other along the guiding direction of the object to be cut, and the cutting blade is inserted into the insertion grooves. A guide tube with a rectangular cross-sectional shape that guides the object to be cut is inserted into the bearing groove so that the pivot shaft can be freely inserted into and removed from the bearing groove, and within a plane that includes the other two surfaces that are continuous with the above two surfaces in which the insertion groove is formed. is provided rotatably around the above-mentioned pivot shaft, and on the above-mentioned guide tube,
A fixing means is provided for fixing the guide tube to the frame with the cutting blade inserted into the insertion groove.

[Effect]

When attaching the guide tube to the cutting device, insert the pivot into the bearing groove, rotate the guide tube around the pivot to insert each cutting blade into each insertion groove, and attach it to the fixing means in this state. Twist and secure it to the frame. In addition, when removing the guide tube attached to the cutting device from the frame, after releasing the fixation by the fixing means, rotate the guide tube around the pivot in the opposite direction as described above to remove the cutting blade from the insertion groove. At the same time, pull out the pivot from the bearing groove and remove it. If the thickness of the object to be cut changes, replace the guide cylinder with another guide cylinder with insertion grooves formed at intervals commensurate with the thickness of the object.

〔Example〕

1 to 4 show an embodiment of the present invention, and reference numeral 1 in the figures indicates a guide tube. This guide tube 1 has a rectangular cross-sectional shape, and a plurality of insertion grooves 2a and 3a (19 in the figure) are formed on the upper surface 2 and lower surface 3 at predetermined intervals. In parallel, the length direction of the guide tube 1 from the center of the guide tube 1 to the left discharge end in FIGS. 1 and 2,
In other words, it is formed along the guiding direction of the object W to be cut, such as bread. In addition, recesses 2 are provided at the inner depths of the insertion grooves 2a and 3a on the upper surface 2 and lower surface 3 of the guide tube 1.
b, 3b are formed, and the recesses 2b, 3b are formed.
3b, a guide piece 4 having a guide groove 4a is removably attached with a screw 5 with the guide groove 4a aligned with the insertion grooves 2a and 3a. Insertion groove 2
3a and 3a are for inserting the cutting blade 6 into the guide groove 4a of the guide piece 4, and the guide groove 4a of the guide piece 4 reciprocates up and down in FIG.
This guides the cutting blade 6 that cuts the material and prevents the cutting blade 6 from wobbling laterally. Therefore, the width of the guide groove 4a is set to be approximately the same as the thickness of the cutting blade 6 (slightly larger), and the opening end is formed to expand outward, so that the groove width is sufficiently larger than the thickness of the cutting blade 6. It communicates with the insertion grooves 2a and 3a which are enlarged in size.

On the right side surfaces 7, 7 of the guide tube 1 in FIGS.
A fixing device (fixing tool) that fixes the guide tube 1 to the frame 8 using bolts etc. with the cutting blade 6 guided in the guide groove 4a of the guide piece 4 means) 11 are provided. Note that the upper and lower surfaces 2, 3 of the guide tube 1 and the receiving ends 2c, 3c, 7a of the side surface 7 connected thereto are formed in an outwardly expanding shape so that the workpiece W to be cut can be received accurately. The cutting blade 6 is attached to a tool post 12.

Further, reference numeral 13 is a separation plate disposed on the downstream side of the guide tube 1 (on the left side in FIGS. 1 and 2). This separation plate 13 is used to divide bread, etc., which have been cut into a predetermined thickness by the cutting blade 6 and sent out from the discharge end of the guide cylinder 1 onto the bottom plate 14, into a predetermined number of sheets (the one in the figure is a It is supported by a support rod 15 so as to be adjustable in the axial direction of the support rod 15. In Figure 1, the upper and lower separating plates 1
3a is for eliminating the ears of bread.
A nut member 16 is screwed onto the tip of the pivot 10, so that the guide tube 1 can be finely adjusted in the axial direction of the pivot 10.

Next, the operation of the guide device for the object to be cut in the cutting device according to the present invention configured as described above will be explained.

1 and 2 show the installed state of the guide tube 1 in which the cutting blade 6 is inserted into the guide groove 4a of each guide piece 4 and fixed to the frame 8 by the fixing means 11. In this case, while reciprocating the cutting blade 6 up and down by a necessary reciprocating drive device (not shown), an object W to be cut such as bread is fed from the right open end of the guide tube 1 as shown in FIG. moves along the guide tube 1, approaches the cutting blade 6, and is cut to a predetermined thickness. The bread and the like cut by the cutting blade 6 are immediately divided into three groups by a separating plate 13, slide on a bottom plate 14, and are transferred to a packaging device (not shown) or the like.

When changing the cutting thickness of bread, etc. by replacing the cutting blade 6 or replacing the tool rest 12 to which the cutting blade 6 is attached, release the fixing of the guide tube 1 by the fixing means 11 and remove the guide tube 1 from the fixing means 11. After rotating the tube 1 counterclockwise in FIG. 2 about the fulcrum of the pivot 10 to extract the cutting blade 6 from the insertion grooves 2a and 3a, pull up the guide tube 1 and attach the pivot 10 to the bearing of the bearing 9. Groove 9
a, remove it from the frame 8, and replace it with another guide tube 1 with a different spacing between the insertion grooves 2a and 3a.

In the above embodiment, the guide piece 4 is connected to the guide tube 1.
Although the cutting blade 6 is guided by being attached to the cutting blade 6, this may be omitted. Further, although the cutting blade 6 of the cutting device is configured to move up and down, it goes without saying that the present invention can be implemented in a cutting device that moves horizontally, diagonally, etc.

[Effects of the invention] As explained above, the guide device for the workpiece in the cutting device according to the invention has two parts facing each other.
A plurality of insertion grooves for cutting blades are formed on the surface in parallel with each other along the guiding direction of the object to be cut, and the object to be cut is guided toward the cutting blade with the cutting blade inserted into the insertion grooves. A guide cylinder having a square cross-sectional shape allows the pivot shaft to be freely inserted into and removed from the bearing groove, and is rotatable about the pivot shaft within a plane that includes two other surfaces that are connected to the two surfaces in which the insertion groove is formed. The guide tube is provided with a fixing means for fixing the guide tube to the frame with the cutting blade inserted into the insertion groove, so that it is easy to cut objects such as bread. In addition to being able to precisely guide the blade to cut to the specified thickness, it is also extremely easy to attach and detach without impairing the guiding function, so even if the cutting thickness changes frequently, no experience is required. Regardless of the situation, anyone can replace the guide tube with another guide tube and perform cutting operations efficiently.
