となつている。(Prior art) Packs with open lids filled with eggs are placed on a belt conveyor and conveyed, and the transported packs with open lids are closed with lid guides, and the other packs that are in close contact with each other are placed on a belt conveyor and transported. A conventional sealer for egg packs, in which the edges are sealed by a rotary sealer consisting of a rotating anvil and an ultrasonic horn arranged along a belt conveyor, has the construction shown in FIGS. 2a and 2b.

シール部seが逃避するのを防止するものである。 In Fig. 2a, 1 is a belt conveyor rotating in the direction of the arrow, 2 is an egg carton conveyed on the belt conveyor 1 and closed by a lid closing guide 3, and 4 is an egg carton. Detecting the arrival of 2...For example, a detection mechanism consisting of a phototube, etc.
5' is a disc-shaped anvil that is rotatably driven by a rotational drive source (not shown) and pivoted to a rotating shaft 51 whose axis is horizontal, and rotates in the direction of the arrow; 6 is a detection mechanism 4;
This is an ultrasonic horn that performs oscillation operation for a predetermined period of time in response to the output signal of the As shown in FIG. 2b, on the peripheral surface of the anvil 5' that rotates along the vertical plane, narrow grooves 52 and peaks 53 are continuously formed along the entire circumference in the direction of the axis of rotation. It is formed. Further, the end face of the contactor 61 fixed to the tip of the ultrasonic horn 6 is arranged so as to face the lowermost circumferential surface of the anvil 5' with a slight gap therebetween. Therefore, the minute gap is set to a predetermined gap equal to or less than the thickness of two synthetic resin sheets forming the egg carton 2, and the rotating circumferential speed of the anvil 5' is set to the moving speed of the belt conveyor 1. The egg carton 2, which is synchronized and conveyed on the belt conveyor 1, is changed from the open lid state shown by dots in FIG.
1. Portion where each edge of the lid 22 is grounded...
...In other words, the part to be sealed shown as se passes through the minute gap (hereinafter referred to as the welded part) MZ,
For example, if the specifications are set so that the seal part se is guided by the guide 7, etc., the seal part se is moved around the anvil 5' which is being rotated by the contact 61 of the ultrasonic horn 6 which is being oscillated while being conveyed. When pressed against the surface, the welding marks shown as m in FIG. 2d are left over the entire length and sealed. In addition, 8 is a support member 81
It is a pressing plate suspended by a weight 82 and has a pressing force adjusted by a weight 82 to hold the egg pack 2 during sealing.
This is to maintain the closed state of the lid and to prevent the seal part se from escaping from the weld part MZ.

対策が求められるところであつた。(Problem to be solved by the invention) By the way, the dimensions of the egg pack 2 differ depending on the size of the eggs packed in it, and the height from the surface of the belt conveyor 1 to the sealing part se differs accordingly. It is necessary to adjust the position of the anvil 5' and the ultrasonic horn 6, and during this position adjustment, it is essential to adjust the minute gap between the welded portion MZ. However, as is well known, synthetic resin sheets are thin, so the fine gap adjustment described above is required to be delicate.
On the other hand, even if the anvil 5' is synchronized with the moving speed of the belt conveyor 1, the uneven egg pack 2 is simply placed on the belt conveyor 1, so its advancing speed does not necessarily match the moving speed of the belt conveyor 1. It doesn't necessarily match the speed. Moreover, the pack is distorted due to various factors such as the adjustment of the weight of the weight 82 of the holding plate 8 which has a very subtle effect, and sometimes the seal part se is sealed with wrinkles. Due to the thickness of the wrinkles that occurred during welding, the egg pack 2 was caught in the welded part MZ, causing accidents such as stoppage of movement and damage to the pack, and countermeasures were required.

The width β of the blank 54 is the seal part of the egg pack 2.
When se passes through the welded part MZ, the cut 54 is rotated and arrives at an early stage when the wrinkles caused by the distortion of the egg pack 2 do not overlap and become thick. It is set so that distortions and wrinkles are released and absorbed into the recesses. If it is possible to cause such an effect, the correlation between α and β...
