Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a feeding method using a vise device in a cutting machine such as a band saw or a grindstone cutting machine.

(Prior art) Conventionally, for example, a cutting machine such as a band saw is shown in Figs.
It has a configuration as shown in the figure. A material support section 3 and a cutting material support section 5 are provided on the base 1, and a cutting section 7 is provided so as to be movable up and down.

The material support section 3 has a large number of support rollers 9, 9...
is supported by a frame 11, and a vice device 13 for clamping the material is provided movably in the feeding direction. In this vise device 13, a feeding fixed vice jaw 15 and a sending movable vice jaw 17 are connected to the cylinder device 1.
It can move forward and backward by the action of 9, and both vice jaws 15
．． 17 to clamp the material W. Also,
The movement of the vice device 13 in the feeding direction is performed by driving the vice bed 23 by a cylinder device 21 provided in the feeding direction in the material support section 3. The movement of the vice bed 23 is guided by a guide shaft 25.

Immediately before the cutting section 7, a main body vice device 27 is provided. This main body vice device 27 is fixed to the base 1 and cannot be moved in the sending direction. In the main body vice device 27, the main body movable vice jaw 31 can be moved forward and backward by the cylinder device 33 with respect to the main body fixed vice jaw 29, and clamps the material 11W.

The cutting section 7 is a band saw blade 35 that is passed between a pair of wheels 39 and 41 within the housing 37. This cutting section 7 can be freely lowered, and the band saw blade 35 cuts the material l+IW.

To explain the cutting operation of the band saw blade having the above configuration, a long material W is placed and supported on the material support section 3, and is positioned at the rearmost position by the vice device 13 as shown by the solid line in FIGS. 13 and 14. It is clamped in this state and sent forward by the driving of the cylinder device 21. Then, the main body vise device 27 clamps and fixes the fed material W.

Subsequently, the vice device 13 unclamps the material W, retreats to the rearmost position, and clamps the material W again here. Then, the main vice device 27 unclamps the material W in reverse.

Subsequently, the vice device 13 sends out the material W forward again by driving the cylinder device 21. After this sending operation, the main body vice device 27 clamps the material W again.

In this way, by reciprocating the vise device 13, the material W is
is sent out longer than the stroke length of the vise device 13,
After that, cutting to size is performed.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional technology, when cutting to a fixed size by sending the device longer than the stroke length of the vise device 13, it takes time for the vise device 13 to return, and time to change the clamp. The problem is that there is a lot of equal loss time.

Furthermore, since the vice device 13 returns and sends the material again, the clamp slips on the material W being sent, resulting in a decrease in delivery accuracy, which poses a problem.

In addition, when sending long materials, if you try to complete the sending with a small number of reciprocations of the vise device, the rod of the sending cylinder device will deteriorate, and the product length will be affected during manufacturing due to deformation of the rod. There are limits and this is a problem.

The present invention has been made in view of the current situation, and it is possible to reduce time loss during sending, improve sending accuracy, and reduce the limit of product length by using a vice device in a cutting machine. The purpose is to provide a method.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention performs a reciprocating motion in which the material is gripped and moved forward, and then the grip is released and the material is moved back. A first vice device and a second vice device are provided, and when one vice device is sending, the other vice device performs a sending preparation operation, and is in operation after sending by the first vice device. The material is received and sent by the second vice device, and by repeating this sending operation, the material is sent to the required size.

(Function) According to the above method, since feeding is carried out using the first vise device and the second vise device, a long product can be manufactured without increasing the length of the rod of the cylinder device. When one vise device is feeding, the other vise device is preparing for feeding, so time loss is reduced. Since the material is received and fed by the second vice device, the vice device during clamping will not slip on the material, and the feeding accuracy will be improved.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 11.

First, an apparatus for implementing the present invention will be described based on FIGS. 1 and 2.

In FIG. 1 and FIG. 2, a material support section 3 provided on a base 1, a vice device 13 serving as a first vice device
, the structure of the main body vice device 27 is the same as that of the above-mentioned conventional example, and the parts indicated with the same reference numerals have the same structure,
It has an effect.

This device is characterized by the structure of the cutting material support section 5. In other words, the cutting material supporting portion 5 includes the cutting material supporting roller 4.
3.43. ... is supported between frames 45.45. Further, a front vice device 47 serving as a second vice device is provided on the cutting material support section 5 so as to be movable in the feeding direction. The front vice device 47 includes a fixed vice jaw 49, a movable vice jaw 51 that can move forward and backward with respect to the fixed vice jaw 49, and a cylinder device 53 that drives the movable vice jaw 51.

Further, the front vise device 37 has a vise bed 57 connected to it by a cylinder device 55 that can be driven in the feeding direction, and is reciprocated in the feeding direction with respect to the main body vise device 27 by the operation of the cylinder device 55.

The movable range of the front vise device 47 is indicated by imaginary lines and solid lines in FIGS. 1 and 2, and is movable to a position directly below the bandsaw blade 35 of the cutting section 7. In addition, in FIG. 2, 59 is a first encoder, which measures the sending distance by the vice device 13 and controls the length measurement of the sending distance by the vice device 13.
61 is for detecting the moving speed of the second
This encoder is used to measure the sending distance by the front vice device 47 and to detect the moving speed of the front vice device 47.

Next, a description will be given based on the flowcharts shown in FIGS. 3 to 11.

First, as shown in FIG. 3, initial processing is performed first, and then sending processing is performed by the vise device 13 and the front vise device 47 (steps 8101 to 5105).

In the initial processing, as shown in Fig. 4, the material W is
The first encoder 59 of the vice device 13 is clamped, and the main body vice device 27 is loosened (unclamped).
The process ends by starting the length measurement at step 81.
07-5113).

The sending process by the vice device 13 is as shown in FIGS. 5 to 7. That is, the vice device 13 performs a sending action, the encoder for the vice length measures it, and then the vice device 13 side performs measurement until the front vise device 47 switches to the sending action and the second encoder 61 switches to measurement. If you continue measuring the length and switch to the measurement of the second encoder 61,
The clamp of the material W in the vise device 13 is loosened, and the movement toward the downstream side of the vise device 13 is stopped (steps 8115 to 8
121). Thereafter, the vice device 13 starts moving upstream and stops moving at the upstream end (step 81
23-8129>.

This stoppage continues until the front vice device 47 performs a sending action and approaches the downstream end. When the front vice device 47 approaches the downstream end, the vice device 13 is moved to the downstream side in order to switch again to the sending action by the vice device 13. (steps 8131 to 5135). Then, the vice device 13 clamps the material W at the same speed as the front vice device 47 (steps 8137 to 5141). Thereafter, the encoder for the sub-length is switched from the second encoder 61 to the first encoder 59, and length measurement by the first encoder 59 of the vice device 13 is restarted (steps 8143 to 8143).
145).

Then, in step 5147, it is checked whether the total count number of the deputy leader is close to the preset value, and if No, the process returns to step 5115 and the above-described sending process of the vice device 13 is repeated, and if YES, the process proceeds to step 5149. The movement of the vice device 13 is decelerated. Then, if the total count number of the vice master matches the preset value, vice device 1
3 stops, the length measurement is completed, and the sending process by the vise device 13 ends (steps 8151 to 5155).
.

Next, the sending process by the front vise device 2t 47 will be explained, as shown in FIGS. 8 to 11.

That is, the front vise @47 is loosened and simultaneously moves upstream (step 8157). The front vice device 47 then moves to the upstream end and stops there (steps 5159 to 5163). Then, as the feeding action of the vice device 13 progresses and the vice device 13 approaches the downstream end, the front vice device 47 starts moving downstream, and when it reaches the same speed as the vice device 13, it transfers the material W. Clamp (steps 5165-8175).

Next, the length measurement encoder is switched from the first encoder 59 to the second encoder 61, and the second encoder 61 of the front vise device 47 starts measuring the length (steps 8177 to 5179). Here, in step 8, check whether the length measurement count is close to the preset value.
181, and if NO, the encoder checks whether the first encoder 59 has been manipulated or not, and returns YE.
If S, the clamp of the material W in the front vise device 47 is loosened, the movement of the front vise device 47 to the downstream side is stopped, and the movement of the front vise device 47 to the upstream side is started, and step 5
Return to step 159 (steps 8183 to 8191).

Then, if the determination in step 8181 is YES,
The movement of the front vise device 47 is decelerated, and if the counted number of length measurements matches the preset value, the movement of the front vise device 47 is stopped and the length measurement is completed (steps 8193 to 81
99).

In the above description, the main body vice device 27 may not be provided. Further, a first vice device and a second vice device are provided upstream of the saw blade, and the material is transferred from the first vice device to the second vice device, and the second vice device holds the saw blade. It is also possible to perform the sending action to the downstream side by crossing the line.

[Effects of the Invention] As described above, according to the present invention, since the first vise device and the second vise device continuously perform feeding, the rod of the cylinder device can be elongated without increasing the length of the rod. products can be easily manufactured, and the design of the cinder device will also be extremely easy. In addition, when one vice device is sending, the other vice device is performing preparation operations at tI+ for sending, so the sending action is not interrupted, and time loss is greatly reduced. In addition, since the first vice device receives the material while it is being sent and sends it to the second vice device, the vice device that is being clamped will not slip against the material, which improves the delivery accuracy. can be significantly improved.
