Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an offset device for material feed in a bandsaw machine.

A band saw machine with an automatic material feeding machine and a groove is known, in which the material is fed into the rotating band saw and cut by the forward movement of the reciprocating material conveyance table, and the process of cutting again after the backward movement is repeated. However, the cut end surface of the material placed on the conveyance table comes into contact with the back of the band saw during the above-mentioned return movement, resulting in unsightly scratches on the cut end surface. This happens when the material is frozen food such as meat loaves.
This is particularly problematic because it occurs noticeably and degrades the value of each painting.

Furthermore, if the loading position of the material changes incorrectly on the conveyor table due to vibration or movement, the back of the band saw will be pushed by the material during the return movement, causing the band saw to slip forward from the pulley. There is a danger that it will come out, and it will also harm work efficiency. Not only is the band saw easily bent, but especially when the material is frozen food, the band saw can become more detached from the pulley due to the adhesion of chips containing oil, fat, and water. Furthermore, since the food is often sliced into thin slices, the above-mentioned problem occurs frequently.

Therefore, when the conveyance table is in operation, it is moved away from the 'JIF saw by a certain distance, and when it moves forward for cutting, it is returned to its original position so as to approach the band saw. It is necessary to transform the trajectory.

The present invention seeks to provide an offset device for material feeding that meets such demands, and its specific details? l
To explain in detail based on the illustrated implementation example in which fj formation is applied to a band saw machine for cutting frozen foods, in Figures 1 to 3, which schematically show the entire band saw machine, (5) is the machine case of the band saw machine. There is a drive pulley storage room (II and driven pulley storage room (2) that can be opened and closed, as well as the drive pulley storage room +11
It also includes a housing for the feeding drive means adjacent to the right side of the housing. (4) is a driven pulley suspended in the driven pulley storage room +21 (51i61 is a driving pulley that is shaft-mounted in the driving pulley storage room +21, and a motor installed to rotate it; An endless @ saw (7) is suspended so as to circulate around the two boobies IJ-+41 and +51, which are vertically opposed to each other. (8) is the material (g) phantom receiving plate, (9) is the lifting and lowering adjustment of the driven boob IJ-1i to carry out the duty and tension operation of the band saw (7). (10j is a flexible wheel that changes the installation position of the machine casing.

(11) is the above-mentioned feed; ・A dedicated motor for the feed installed in the drive means storage chamber +31; +12) is also the gear box, which has a built-in deceleration transmission mechanism using an umbrella 1 yaw wheel (not shown), etc. There is. (One grape is placed on the top of the machine @ (A),
The crank arm moves horizontally and is driven by a motor.The tip of the crank arm is pivotally connected to the criminal carrier tBl, The platform +111 is designed to reciprocate linearly in the front and back direction so that the upper surface of the Ild prisoner is parallel to the plate surface of the band saw (7).
1 consists of an assembly of a slide frame θ and a material mounting table (16) which is integrally attached to the upper surface of the slide frame θ in a cover-like manner. In that case, the table (as suggested by the figure, it has a 5-shape when viewed from the left and right sides, and is attached to the frame plate f14) so that it can be inserted and removed from the right side. By screwing back and removing 6), the inside of the frame board 04) and the table θ5) can be cleaned, and the table itself can be easily replaced. Note that the length of the crank arm (one arm length) can be adjusted, but the reference numerals are omitted.

(171 is a slide guide shaft that reciprocates the transport platform (13+), and is installed horizontally so as to run in the front-rear direction near the right end of the machine casing. (1
In order to securely support the shirt, the barrel cA+
A pair of pillars erected on the upper surface, icl (LII) are also a pair of left and right slide guide rails, and the one on the left side near the force is a free rail (C1) that is simply U-shaped. It is fixed to the upper surface of the conveyor table (Bl) which engages with it and transfers freely due to its U-shaped cross-sectional shape. It is movable, which is probably why it is called the rough free rail.On the left side of the conveyor platform (31) located corresponding to this free rail +01, there is a support from the bottom of the slide frame θ. J wholesale (I9) is hanging down li'il Z
A roller (E) that engages with the free rail IO+ is pivotally supported at its lower end. (211 is that rail (
C1'Th is a skirt plate that hangs down from the left end of the frame plate (one plate), and serves to prevent chips from entering.

On the other hand, the rail on the right at position 11111 V, which is far from the band saw (7), is used as the offset rail tLl+ of the side slanted conveyance table (B), and is set at a constant distance +81 from the band saw (7) only when the conveyance table (U) is subsequently excited. I miss it so that it is far away from me, and I turn it upside down.
During the forward movement when the IJ is cut, the movement and the 1IiL trace are switched so as to bring it back closer to the band saw (7), and the details will be described later. On the right side of this offset moon rail (transport platform (1) located corresponding to Di), a large support leg (24) of a special form is fixedly suspended from the slide frame board (14), and is continuous from the support leg. The tip of the crank arm (1 arm) is connected to the stay (C) that protrudes from the shaft by means of a pivot bolt.

Furthermore, details are evident from the enlarged views of Figures 4-9 (
The shaft (+7) is a concave groove opened approximately in the center of the large support leg 5 to allow the guide shaft 071 to escape, and the shaft (+7) passes through this groove in the front-rear direction. (
4) is a III receiver fitted to the shaft (1η), and connecting pieces !2η hanging integrally from both the front and rear ends of the shaft are connected to the support 1j141+24 itself by a pair of front and rear pivot pins μs. As a result, the end of the bearing cylinder swings in a roughly oscillating manner about the shaft t171, and the conveyance table (0) can move in the left and right planes relative to this. (8) is the support leg (a pair of left and right regulating bolts protruding sideways from 291, both poles) facing the above-mentioned concave groove (2 uniform circles). By pushing it back to the cap holder, it is possible to control the above-mentioned horizontal digging of the transport platform +131 with respect to the shaft (17) in the subsequent state.

In other words, when the conveyance table +81 is laterally moved to the left 1111i position with the shaft αη as the fulcrum, the bolt 4 on the right side protruding from the support leg (2) is attached to the shaft (1
When it collides with η and moves the conveyance platform (B) laterally to the right position, this time it moves to the left side as shown in Figure 8) 12'l
(17), consideration has been given to ensuring that each state after horizontal movement can be restrained securely at all times without wobbling or other wobbling. In that case, in relation to changing the amount of horizontal lateral movement of the transport platform tBl (,l: interval distance (S) from the band saw (7)), the shan)
Of course, the impact position relative to t171 can be adjusted by moving the CI forward or backward.

(The rope is a mounting tube that continuously hangs down from approximately the center of the support leg, and a roller (2) that engages with the offset rail (1) is pivotally supported on this. It can be seen from the figure that while the above-mentioned locking roller 4 with the free rail (9) rolls around the horizontal axis 9, this roller CIl+ rolls around the vertical axis. As suggested. 13''4 is the same support leg (the spring holder hanging down from the middle of the @ is a pin, 133) is a cam wall plate with a vertical cross section that is fixedly suspended from the right end of the support leg, and is not visible from the plane. It has a substantially triangular image shape when viewed from above, and is provided with an inclined cam surface that is formed from the upright wall plate surface.

Also, 3 [ is the opening/closing wall board that is lowered from the support leg (from Jun!), adjacent to the front part of the cam wall board, and has a multi-cut, vertical shape, and supports the support leg. It is attached to the lower surface of the leg (5) via a support piece (to) and a pivot pin (07) so as to be rotatable around the vertical axis. During this period, the closed wall plate has a slender and approximately triangular shape in the plane Ifi view, with a slanted cam surface (corresponding to the 9th cam surface of the cam wall plate 31, and an slanted end direction (c) that connects with it by '7f). By bringing the cam surface (341) and the end RFU into close contact with each other, the upright wall plate surfaces of both wall plates (3 and 41) are continuous with each other without gaps or steps, and are aligned flush as a whole. It has become.

This is intended to allow the rollers of the intermediate switching rail (of the offset rail described later) to roll smoothly.

(39) is a tension coil spring that elastically biases the opening/closing wall plate side, which can be rotated by the movement of the pivot pin 0η, so that it is always in a closed state with the end of the cam wall plate. The hanging spring receiver is connected between the bottle U1 and the vicinity of the tip of the opening/closing wall board 34. Therefore, it is not easily visible from the outside world. Inclined cam surface 134+ at the end of the cam wall plate
has a certain length I,) and %! 5: Closing wall plate C is curved as an upright wall plate surface that blocks the entire curved interior, so to speak, so that it smoothly engages with the rollers of the switching rail and causes it to roll. At that time, the opening/closing wall plate side is forced to open and rotate due to the poor contact with the cam wall plate due to the rollers (against the spring flash). This is the path suggested in Figure 9.

As shown in Figure 9, the top offset rail +1)l is the fixed rail (Itl) that faces to create a tree cam surface, and its inside. +l'# 1ili

It extends in the front-rear direction. (The four pillars are the mounting pillars for the solid structure, and are fixed to the top of Prisoner Shun 1z.

The decoy is a seat plate that allows the switching rail gage I) to move laterally correctly, and the fixed rail (I [I) is integrated so as to cut between the lower stations of l. There are nine horizontal branch roots that are fixed and integrated with the switching rail tia so that the support I# (2

: Since the rail t+1 is connected to the fixed rail (4) as shown by the chain line in Fig. It is always biased towards the left i++u position in INj.

Corresponding to the relationship (7) between the side slanted food feeder iLl+ and Ib・ζ, the roller 01) hanging from the support leg - of the 7+Jx feeder tlJl is the offset rail (D+). Since the switching rails t and 4II are designed to fully roll in the groove, when the switching rails t and 4II are in the left position in the groove on the fixed rail p+J, the conveyor table (13) cannot be moved by the band saw (
7), and the state in which the switching rail (41) has moved to the stone side position indicated by the arrow in the top panel is similar to the state in which the switching rail (41) has moved away from the conveyor platform (41) by a certain distance +81. I
This means that ll is approached to the band saw (7). As suggested from the figure, the switching rail ←l) forms a 111↑ force surface that is continuous with the fixed rail (49). (It is equal to 81. Incidentally, the distance +81 is approximately 10171111. It is preferable that the switching rail (41) is a synthetic i*j I front mounting to prevent the strange noise caused by metal touch. , transport platform +
131 is reciprocated along the L plane of the crank arm (by the crank movement of one arm) in the front and back direction, and at 1 o'clock when it moves backward, it approaches the band saw (7) and moves on a trajectory. Thus, the material - is subjected to the cutting action by the saw teeth yc, and conversely, when moving back forward, the carrier +IJ+ returns along a trajectory that moves away from the band saw (7).

Then, the solid line in the WJ+-e- diagram indicates the forward movement start stage of the material transport platform (IJ), and at this time, the transport stage +1111
A switching rail (41) is attached to the continuous and flush standing wall plate surface of the cam wall plate and the opening/closing wall plate 131il hanging from the cam wall plate.
The roller Iia is engaged against the tension coil spring i4, and therefore the switching rail (41) is drawn to the right position in the groove in the fixed rail hook by the spring @6. Therefore, the carrier +il+ can be moved forward as a trajectory approaching the band saw (7).

In that case, the roller (4υ) of the switching rail Il+ will be transferred while engaging with the above-mentioned upright wall plate surface, but when it reaches the halfway stage of its forward movement, as shown by the chain line in Fig. 1844, its retention However, at this time, the roller @ll hanging down from the conveyor table (Bl) is in a state of locking transfer with the switching rail (41), and the tensile action by its spring 146 is killed, so to speak. Since there is, just circle i'
ft K The forward movement continues, and as soon as the forward movement end stage (backward movement start stage) is reached, the switching rail I4 is automatically and Instantly, it is pulled to the left (1 position) in the groove on the fixed rail (10).Therefore, the transport platform (B)?This time, the trajectory moves away from the band saw (7) by a certain distance (81). It is possible to return along the lines.

Therefore, once the backward motion is started, the roller t311 of the conveyance platform (+3) is
Although it is in a coherent rolling state with υ, the bond will eventually be released as shown by the first solid line. From this point on, the roller t4i of the switching rail (41) engages with the cam wall plate (331) hanging down from the transfer platform (Bl) so as to be scooped up, and the cam surface (3→ In this case, the roller i4 hill opens and rotates the peeling wall plate i: (2) against its coil spring end. As the switching rail @1) is drawn to the right position in the groove of the fixed rail 4) by the tensile force of the coil spring (8), the forward movement starts as shown by the solid line in the self-excited VC chord diagram. returned to the state,
