When the operation start switch (not shown) is turned on at time t1 in FIG. 4, the plurality of works W stacked on each other are turned on by the work input motor 110 as shown in FIG. When the work is started to rotate and the work input conveyor 120 is driven to rotate clockwise as viewed from the direction of FIG. 1, the work is conveyed rightward so as to be sequentially removed one by one from the lower side of the stack. At this time, if many works W are stacked on the work W to be conveyed, the load is applied and a large frictional force is applied between the works W, so that the extraction cannot be achieved satisfactorily. In order to cope with this, the leading end side of the work input conveyor 120 in the transport direction is inclined upward, so that the load received by the lowermost work W from the upper work W is reduced. This inclination angle is equal to the work W
The angle can be freely adjusted with the screws constituting the inclination angle adjusting mechanism 130 in accordance with the above.

The work W transferred from the loading station S1 to the sticking station S2 is rotated by the work / tape transfer motor 210, and the work transfer conveyor 220 is moved to the position shown in FIG.
Is rotated clockwise as viewed from the direction of, so that the reference plane on the near side is guided on the work transfer conveyor 220 from left to right at a predetermined speed. A rising signal is detected at a time t2 in FIG. 4 by a work input confirmation sensor (not shown) shown in FIG. 4 (j) provided in the middle of the work transfer conveyor 220, and the work W is transferred to the attaching station S2. When the completion is confirmed, the work input motor 1 in the input station S1

Further, when the tip position of the sticking station S2 in the transport direction of the work W in the transport direction is detected as a rising signal at time t3 in FIG. 4 by a work tip confirmation sensor (not shown) shown in FIG. As shown in FIG. 4B, a clutch & brake unit 251 to be described later is operated, and the delivery of the tape T set to be equal to the transport speed of the work W is started. Then, one side portion of the predetermined width of the tape T on the far side is attached to the peripheral surface on the lower surface side adjacent to the reference surface on the near side of the work W.

When the end position of the work W in the transport direction is detected as a falling signal at time t4 by a work end confirmation sensor (not shown) as shown in FIG. 4), the electromagnetic solenoid 242 described later is driven one reciprocation to cut the tape T, and as shown in FIG. 4B, the clutch & brake unit 251 is operated and the roll-shaped tape T on the supply side is actuated. Is stopped. The length of the tape T cut at this time is the length of the tape W to be attached to the work W. The width of the tape T to be attached to the back surface of the work W at the attaching station S2 is 40 mm in width of the tape T, About 10 width
mm, the sticking position is set in advance so as to be about 15 mm. Further, when the tape T stuck on the peripheral surface on the lower surface side of the work W is conveyed over the sticking station S2, the tape bending member 270 causes the remaining width of about 2 mm.
5 mm is bent upward by 90 ° and attached to the reference surface side of the work W.

The work W on which the tape T is stuck as described above is conveyed to the next payout station S3, and is simultaneously rotated by the work / tape conveying motor 210 which rotates the work conveyer 220 in the sticking station S2. The guide surface on the near side is guided at a predetermined speed from the left to the right while being guided on the driven work transfer roller conveyor 310. Then, as shown in FIG. 4 (m), the arrival of the work W to the final end of the work transfer roller conveyor 310 is detected by a work arrival confirmation sensor (not shown) at time t5.
As shown in FIG. 4 (h), the work pulling motor 320 starts rotating and the work pulling mechanism 330 having the work pulling wall 331 waiting on the back side is driven as shown in FIG. Started and the work drop-in wall 33
1 is temporarily moved from the right side to the left side as viewed from the direction of FIG. 3, and then returned to the original right side position. Thus, at the drive end position in one reciprocating operation of the work retraction mechanism 330,
As shown in FIG. 4 (n), a rising signal is detected at time t6 by a work pulling stop sensor (not shown), and the rotation of the work pulling motor 320 is stopped.

The work W on the work transport roller conveyor 310 is drawn from right to left in FIG. 3 by one reciprocating movement of the work drawing wall 331 by the work drawing mechanism 330. At this time, about 15 mm of the remaining width portion projecting upward from the end face of the work W is bent at once at the upper side of the work W by the tape sticking completion mechanism 350, and the sticking is completed. Thereby, the work W is completely sealed at the end face on the facing side, and the work payout motor 361 is provided.
The work is delivered to the near side when viewed from the direction of FIG. That is, the transport system for the workpiece W of the end face sealing device 100 is configured to have an L-shaped path.

Next, the tape sending / sticking mechanism 230 for sending the tape T of a predetermined length at the sticking station S2 of the end face sealing device 100 and sticking it at a predetermined position of the work W will be described in detail with reference to FIGS. Will be described. FIG. 5 shows the tape sending / pasting mechanism 23 viewed from the same direction as FIG.
FIG. 6 is an enlarged front view showing a configuration of a main part of FIG. 5, and FIG. 6 is a sectional view of the main part of FIG.

First, a single-sided glue tape T having a width of 40 mm and a roll shape is attached to the base 231 by an attachment handle 233 via an attachment plate 232. The mounting plate 232 urges the side surface of the roll-shaped tape T with a predetermined spring pressure to apply a predetermined tension when the tape T is sent out. Then, the tape T is sandwiched between the comb tooth roller B 237 and the driven roller 238 via the tension roller 234, the tape driving roller 235 and the driven roller 236, and the tip of the tape T is rotatably fixed to the tape cutting motor 240. The tape is cut out to an initial position substantially equal to the tip position of the tape cutting blade 241. The tension roller 234 is always urged by a spring (not shown) and
Absorb the slack. The driven rollers 236 and 23
Reference numeral 8 is constantly urged by a spring (not shown) and pressed against the tape T.

One of the comb-tooth roller B 237 and the driven roller 238 is a curved convex at a predetermined curvature, and the other is a curved concave. Incidentally, in the present embodiment, the comb roller B237 is concave and the driven roller 238 is convex. The structure in which one is a curved convex at the predetermined curvature and the other is a curved concave is to give the tape T a stiffness, and when the tape T is sent out in a flat plate shape, its own weight or Although it may bend due to static electricity, humidity, etc., the tape T itself after being cut by the tape cutting blade 241 by bending and feeding the tape T itself,
It will be moved substantially linearly in the predetermined sending direction. In particular, in the present embodiment, the comb roller B 237 and the driven roller 238 do not have curved surfaces, and the tape driving roller 235 and the driven roller 236, the comb tooth roller A247
And the conveyor drive roller 250 also have uneven surfaces that are mutually curved. In the present embodiment, the surface of the tape T that is not the glued surface is the convex side.

As described above, when the initial setting for the tape T is completed, the tape presence / absence confirmation sensor 239 is turned on to prepare for the operation preparation, and the operation preparation switch (not shown) is turned on at time t0 as described with reference to FIG. Is done. Then, when the tape cutting motor 240 is turned on, the tape cutting blade 241 is turned on.
Is rotated, and when the tape suction fan motor 245 is turned on, it is surrounded by the tape suction conveyor 246 having a number of small holes corresponding to the width of the tape T, and is covered except for the transport surface of the tape T. Since the internal area is in a negative pressure state and the V-belt-combed roller A247 is rotated counterclockwise when the work / tape conveyance motor 210 is turned on, it is driven by the driving gear 248 fixed coaxially. The conveyor driving roller 250 is rotated clockwise via the gear 249, and the tape suction conveyor 246 is rotated clockwise. At this time, the comb tooth roller A24
In the comb-tooth roller B 237 with the V-belt hung on 7, the clutch & brake unit 251 disposed on the same axis is off and the rotation stop state is maintained, and the tape T is not sent out at this time. . Here, the comb tooth roller A2
47 and the comb-tooth roller B 237 have a comb-shaped outer peripheral surface and are combined so as to mesh with each other, thereby preventing the leading end of the tape T from being stuck. The tension roller 234, the tape drive roller 235, the driven roller 2
38, the conveyor driving rollers and the like have a convex curvature at the center of the width, and the deviation in the width direction during the conveyance of the tape T is automatically corrected, and the tape T is curved in the width direction by the curvature of each roller. This allows the tape T to have some stiffness and to be easily cut by the tape cutting blade 241. Further, the driven roller 236, the comb-tooth roller B237, and the comb-tooth roller A247 on the side in contact with the adhesive surface of the tape T
Is formed of a fluororesin or the like so that the adhesive strength of the tape T does not reach.

Next, the workpiece W is transported on the workpiece transport conveyor 220, and as shown in FIG. 4 (k), when the workpiece tip confirmation sensor is turned on, the clutch & brake unit 251 is turned on, and the comb teeth are turned on. The comb-tooth roller B237 hung on the roller A247 by the V belt is rotated.
Further, the tape drive roller 235, which is hooked on the V-belt on the comb tooth roller B237, is rotated. Thus, the tape T is started to be sent out in synchronization with the leading end position of the work W conveyed on the work conveyance conveyor 220, and the tape T is rotated by the comb-tooth roller A247 and the conveyor drive roller 250. Is sent between After that, the tape T is transferred to the tape suction conveyor 246.
It is transported while being adsorbed on the surface. Then, when the leading end position of the tape T reaches the tape attaching position after a predetermined dimension from the leading end position of the work W conveyed on the work carrying conveyor 220, the sticking of the tape T to the work W is started. At this time, since the transport speed of the work W and the sending speed of the tape T are set to be the same, the tape T
Is attached along a predetermined peripheral surface of the lower surface of the work W without extending and contracting.

On the other hand, as shown in FIG. 4 (l), when the work end confirmation sensor is turned off, that is, when the end position of the work W is detected, as shown in FIG.
When the 42 is turned on, the tape cutting blade 241 rotated and driven by the integrated tape cutting motor 240 is inserted into the sending locus of the tape T, and then the electromagnetic solenoid 2 is turned on.
As soon as 42 is turned off, it is returned to the original position using the biasing force of the return spring 243. At the same time, the clutch & brake unit 251 is turned off and the comb tooth roller B23 is turned off.
The sending of the tape T before the stage 7 is stopped. After this,
Only the tape T cut to a predetermined length corresponding to the work W by the tape cutting blade 241 is a tape suction conveyor 246.
The workpiece W is conveyed while being attracted to the surface, and is subsequently adhered to a predetermined peripheral surface on the lower surface of the work W. Immediately after the tape suction conveyor 246, a pressing roller 261 for securely attaching the tape T to the work W is provided. Although not shown in FIG. 5, a pressing roller for pressing the work W downward to stabilize the work by pressing the work W downward is disposed above the position where the tape T is stuck to the work W on the work transfer conveyor 220. I have.

Thereafter, in the attaching station S2, the remaining width of the tape T attached to the lower surface of the work W is transferred to the tape bending member 270 fixedly opposed to the reference surface side of the work W of the work transport conveyor 220. As a result, the work W is bent toward the reference surface side. This operation will be described with reference to FIG.

As shown in FIG. 7A, the remaining width of the tape T attached to the lower surface of the work W is
7B, when the remaining width of the tape T abuts on the inclined surface 271 of the tape bending member 270, as shown in FIG.
By being bent, the remaining width portion of the tape T is attached to the reference surface side of the work W.

Next, the work drawing-in mechanism 330 and the tape sticking completion mechanism 350 in the payout station S3 will be described in detail with reference to FIGS. FIG. 8 is a schematic diagram showing a configuration of a main part of the work drawing-in mechanism 330 omitting the work transfer roller conveyor 310 part.

As shown in FIG. 4 (m), the arrival of the work W transferred from the work transfer conveyor 220 of the sticking station S2 to the work transfer roller conveyor 310 of the payout station S3 to the final end is detected by a work arrival check sensor. When detected, the work drawing motor 320 is turned on.

Thereby, the retraction arm 321 is rotated once by the rotation of the work retraction motor 320, and the work retraction wall 331 is moved along the rods 335a and 335b arranged in the retraction direction via the integral bushes 334a and 334b as shown in FIG. By performing one reciprocating operation from the state shown, the work W is paid out to the tape sticking completion mechanism 350 side.

At this time, the work W is attached to the sticking station S where the remaining width of the tape T is projected from the reference surface side to the upper surface side.
2 remains in the attached state. The work W is paid out to the tape sticking completion mechanism 350 side, and the driving roller 351 and the driven roller 35 rotated by the tape sticking motor 340.
