Built-in.

Next, the operation of the lid tightening device shown in FIGS. 3 and 4 will be explained. When the turntable (5) is rotated by a drive device (not shown), the turret frame α (A) integrated with the turntable (5) is rotated, and the rotation of the turret frame α causes the upper annular rail (4) to rotate. ) The lower part of the cam 7, which is engaged with the cam groove of the roll-on cap, moves the roll-on cap tightening head up and down. Furthermore, when the turret frame a4 rotates, the planetary gear Q4) rotates and rotates the roll-on cap tightening head (c), but the conical cam (
5) and the pressure block (goods) do not rotate. On the other hand, due to the rotation of the turret frame a4), the lower annular rail (
The cam follower (C) engaged with the cam groove 12) moves the conical cam (5) up and down. The platform on which the conical cam C27) is lowered relative to the cam roller G is moved by the conical cam C27 while the cam roller 0 rotates against a spring device (not shown) that presses the cam roller 0 against the conical cam.
) and the pivot arm (to) rotates. The reverse is also true. The rotation of the pivot arm (31) is transmitted to the pivot arm (31) via the pivot shaft, which rotates the arm (01) to rotate the forming roll.
Move the roll-on cap tightening spatula in and out with respect to the axis of C351. Roll-on cap (8
The operation of the two fitted bottles (8) from when they are gripped by the bottle gripping device (7) until the capping is completed is as follows.

First, the roll-on cap tightening head (c) descends,
The tip of the pressure block (B) presses down the p-luon cap (8') due to the elastic force of the built-in spring, and when it descends further, the roll-on cap (8) is pushed down by the elastic force F□ of the spring (19). Shape the top part as shown in Figure 4,
When the forming roll Q reaches a predetermined position, the conical cam (5) rises against the cam roller G, and the illustrated boning device presses the forming roll (to) against the outer periphery of the roll-on cap (8 roll-on caps. Since the roll-on cap tightening head c39 is rotating with respect to the bottle (8), if the trough of the spiral groove of the bottle (8) and the pressure contact part of the forming roll (to) match, the roll-on cap (8) is rotated. ') is deformed, and then the forming roll (to) is guided while rotating by the spiral groove of the bottle (8), and when it reaches the end of the spiral groove,
Formed in the shape of a screw cap. Thereafter, the conical cam holder descends relative to the cam roller C33 to release the forming roll (to) from the tensioned roll-on cap (8'), and further raises the roll-on cap dispensing head (c) to open the bottle ( 8) Complete preparations for the next action, such as discharge. In addition, multiple roll-on cap tightening heads (G) are arranged on the circumference of the coolet frame a→, so
During one rotation of the 10 turret frames, in addition to the above-mentioned wire tensioning operation, functions such as bottle feeding and discharging are also performed.

In the wire tensioning device shown in FIGS. 3 and 4, the tension vertical load necessary to deform the eight tops of the roll-on cap is applied by the elastic force F1 of the compression spring as described above. Since the pressure mechanism that performs this consists of multiple parts, on an actual production line, the vertical load on the wire may not act on the roll-on cap (8') at a truly appropriate value, resulting in a lack of wire tension. Insufficient wire tension will impair the quality of the filling, so this must be avoided, but with the configurations shown in Figures 3 and 4, it is difficult to detect the tension in-line, and the filling It was necessary to manually inspect the quality of the products.

The present invention addresses the above-mentioned problems, and includes a turntable for conveying bottles in an array at equal intervals, an annular rail disposed above the turntable, and a distance from the turntable in the circumferential direction. It has a cam groove provided on the annular rail and a spindle assembly with a wire tensioning head at the bottom, and the spindle assembly moves along the cam groove in synchronization with the turntable. In the wire tensioning device, there is a split rail that divides a part of the annular rail to enable upward movement, and a split rail that restricts the upward movement of the split rail and reduces the load that is applied to the split rail when regulating the split rail. The purpose of the wire tensioning device is to provide an improvement in which the wire tensioning force can be reliably detected in-line and manual quality inspection can be omitted. The purpose of the present invention is to provide a wire tensioning device that can be used in a variety of ways.

Next, the wire tensioning device of the present invention will be explained with reference to an embodiment shown in Figs. 1 and 2. (4') (The parts other than 4n - Indicated by a symbol. Next, to specifically explain the differences, (4'2) divides the part of the upper annular rail (4) corresponding to the tensioning completion position to enable upward movement. divided rail, (4-
1) (4'-1) is the same upper annular rail (4) and the divided rail (4 cam grooves provided, and the same cam groove (4-1)
(4'-1) differs in distance from the turntable (5) in the circumferential direction. (46') is the spindle assembly, Cη is the plate fixed to the upper annular rail (4) with bolts, (4 barrels are the brackets fixed to the upper annular rail (4) with bolts, 09.) With the load cell (load cell) attached to the same bracket ■,
The four rails contact the four divided rails and are connected to a display device (not shown).

Next, the operation of the wire tensioning device shown in FIGS. 1 and 2 will be explained. When the coolet frame (see (14) in Fig. 3) moves in the direction of the arrow, the spindle assembly (46') passes through the divided rail (4') one after another, and the bottles (towards) (directly The reaction force that pressurizes the roll-on cap) passes through the split rail (4') to the detection part of the load cell (09), and the reaction force is detected by the load cell (c).
! The detection signal obtained in step 11 is sent to a display device and displayed there. Note that even if the split rails (4) receive pressure from the vertical load of the tension wire, the receivers are stopped by the load gauge keel and do not move, so the cam grooves (4) of the upper annular rail (4)
-1) There is no problem in moving the cam follower α9 in the cam groove (4L1) connected to the cam groove (4L1). Also, normally the support plate G17) supports the divided rails (4 pieces).

As described above, the present invention includes a turntable that conveys bottles in an array at equal intervals, an annular rail disposed above the turntable, and an annular rail arranged so that the distances to the turntable are different in the circumferential direction. A scanning line that has a cam groove provided in an annular rail and a spindle assembly with a wire tensioning head at the bottom, and the spindle/l/m solid moves along the cam groove in synchronization with the turntable. In the device, a split rail that divides a part of the annular rail to enable upward movement, and a load that restricts the upward movement of the split rail and detects the load applied to the split rail when regulating the same. Since the above-mentioned function is performed, the tension force can be accurately detected in-line, and manual quality inspection can be omitted.

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various design modifications can be made without departing from the spirit of the present invention. .
