Description

[Technical Field]

[0001] The present invention relates to a sealer assist device. [Background technology]

[0002] BACKGROUND ART Conventionally, a sealing device, so-called a sealer, has been known for sealing a product with a plastic film packaging material or the like when packaging the product.

[0003] Such sealers include impulse sealers, which instantaneously pass a large current through a heater wire to heat it and thermally seal the opening of a packaging material, etc., and ultrasonic sealers, which apply a high-frequency voltage to the opening of a packaging material while it is pressed and pressurized, generating heat through high-frequency dielectric heating to thermally seal it. Various inventions related to such sealers have been made (see, for example, Patent Document 1).

[0004] Patent Document 1 discloses a stretch film dispenser and a stretch packaging machine equipped with the same, which can wrap stretch film directly around a pallet on a rotating table, and after the first wrap is done with a slight tension, can wrap the stretch film while controlling the tension to any desired strength.

[0005] [Patent Document 1] Japanese Patent Publication No. 2022-15917 [Patent Document 2] Japanese Patent Application Laid-Open No. 2010-70207 Summary of the Invention [Problem to be solved by the invention]

[0006] With regard to the above-mentioned sealers, so-called tabletop sealers, which are miniaturized for personal and household use, are widely used. Fig. 1 shows an example of a conventional tabletop sealer. The tabletop sealer 100 shown in Fig. 1 has a main body 110, a heating time adjustment unit 120, a sealing unit 130, and a crimping lever unit 140.

[0007] The main body 110 is formed in a box shape with a trapezoidal or pentagonal cross section, and forms a seal portion 130 between itself and the crimping lever 140. The heating time adjustment portion 120 is an adjustment knob for setting the heating time in advance according to the material and thickness of the object to be sealed. The seal portion 130 is composed of a lower seal portion 131 on the main body 110 side and an upper seal portion 132 on the crimping lever 140 side.

[0008] The pressure lever portion 140 is rotatably supported on the main body portion 110 via a rotation shaft 150, and is configured in the shape of an arm having a predetermined length. A handle (push hand) 141 is attached near the tip of the pressure lever portion 140 so that it can be easily pushed by hand.

[0009] However, conventional tabletop sealers 100 cannot be operated with a foot because they are designed to be operated by hand by pressing the handle 141 of the crimping lever portion 140. On the other hand, although foot-operated sealers have existed in the past, it has not been possible to convert an existing tabletop sealer 100 into a foot-operated sealer.

[0010] The present invention has been made in consideration of the above points, and has as its object to provide a sealer auxiliary device that can convert a tabletop sealer into a foot-operated sealer. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, the sealer auxiliary device of the present invention is a sealer auxiliary device that is attached to a sealer having a main body and a crimping lever that rotates relative to the main body, and is characterized by comprising a support stand that holds the sealer at a predetermined height, a stage attached to the support stand on which the object to be sealed is placed, and a foot pedal that is slidably attached to the support stand and connected to the crimping lever via a connecting shaft. [Effects of the Invention]

[0012] The sealer auxiliary device of the present invention is a sealer auxiliary device that can be attached to a sealer having a main body and a crimping lever, and is equipped with a support stand, a stage, and a foot pedal, so that its extremely simple structure allows existing tabletop sealers to be converted into foot-operated sealers.

[0014] (composition) Hereinafter, an embodiment of the present invention will be described. First, a description will be given of the configuration of a sealer system S including a sealer auxiliary device 2. As shown in Figs. 2 to 5, the sealer system S of the present invention is composed of a manual tabletop sealer 100 as a sealer and a sealer auxiliary device 2.

[0015] Of these, the manual tabletop sealer 100 has a main body 110, a heating time adjustment unit 120, a sealing unit 130, and a pressure lever unit 140, as described above with reference to Figure 1. In other words, the tabletop sealer 100 has the main body 110 and the pressure lever unit 140 that rotates relative to the main body 110.

[0016] A sealer auxiliary device 2 is attached so that this manual tabletop sealer 100 can be converted (reused) into a foot-operated sealer. The sealer auxiliary device 2 includes a support stand 3 that holds the tabletop sealer 100 at a predetermined height, a stage 4 attached to the support stand 3 and on which the object to be sealed is placed, and a foot pedal 6 that is slidably attached to the support stand 3 and connected to the crimping lever part 140 via a connecting shaft 51.

[0017] The support frame 3 is a frame body formed by a hollow rectangular pillar of metal or the like, and is composed of a U-shaped base portion 31, a pillar portion 32 of a predetermined length (height) that rises from the base portion 31, and a support base portion 33 fixed near the upper end of the pillar portion 32.

[0018] A bracket portion 32a protruding in a substantially horizontal direction is provided midway along the column portion 32. A circular hole is provided in the bracket portion 32a, and the connecting shaft 51 is inserted to guide it. The support base portion 33 has two circular holes on which the tabletop sealer 100 is placed, and through which the connecting shaft 51 and the slide shaft 52 (described below) are inserted to guide them.

[0019] Furthermore, stages 4A and 4B on which the objects to be sealed are placed are attached to the support base 33 of the support pedestal 3 in this embodiment. The stage 4A on the front side (front face) has a wide flat plate portion 40 on which the objects to be sealed are placed, and arm portions 41, 41 that extend by bending both sides of the flat plate portion 40. An elongated hole is formed in the arm portion 41, and the arm portion 41 is attached to a bracket on the support base 33 side via a screw 42 so that the arm portion 41 is slidable and rotatable. The stage 4B on the back side (rear face side) is fixed to the support base 33.

[0020] The connecting shaft 51 contacts the pressure lever portion 140 near its upper end, and has the foot pedal 6 attached near its lower end. A rotating roller 53 is rotatably supported near the upper end of the connecting shaft 51 via a bracket portion 54. That is, the connecting shaft 51 contacts the vicinity of the center of the upper surface of the pressure lever portion 140 via the rotating roller 53. The sliding direction of the connecting shaft 51 is regulated (guided) by (a circular hole provided in) the bracket portion 32a of the column portion 32 and (a circular hole provided in) the support base portion 33.

[0021] The rotating roller 53 is attached near the upper end of the connecting shaft 51 via a bracket portion 54. The rotation axis of the rotating roller 53 is oriented so as to be perpendicular to the direction in which the pressure lever portion 140 extends. In other words, the rotating roller 53 rotates along the direction in which the pressure lever portion 140 extends. This allows for smooth transmission of force from the connecting shaft 51 to the pressure lever portion 140. In other words, since the pressure lever portion 140 rotates (oscillates) relative to the main body portion 110, in order to press the same position on the top surface of the pressure lever portion 140, it is necessary to configure the upper surface of the pressure lever portion 140 to slide.

[0022] A slide shaft 52 is installed parallel to the connecting shaft 51. That is, the slide shaft 52 is fixed parallel to the connecting shaft 51 to a bracket portion 54 fixed near the upper end of the connecting shaft 51. The lower portion of the slide shaft 52 is slidably inserted into a circular hole provided in the support base portion 33. Therefore, the connecting shaft 51 and the rotating roller 53 integral with it have their directions regulated (guided) by the two shafts, the connecting shaft 51 and the slide shaft 52.

[0023] The foot pedal 6 is a rod-shaped member attached near the lower end of the connecting shaft 51. By stepping on (pushing down) the foot pedal 6 with your foot, the connecting shaft 51 that is integrated with it moves downward, and therefore the rotating roller 53 also moves downward. The foot pedal 6 is located at a low position, making it easy to step on by putting your weight on it.

[0024] (action) Next, the operation of the sealer auxiliary device 2 of this embodiment will be described with reference to Figures 3 and 4 before sealing and Figures 6 and 7 after sealing. Prior to operation, the stage 4A is rotated to change the angle and slid to adjust the angle and position so that the object to be sealed can be easily sealed.

[0025] 3 and 4, before sealing, the rotating roller 53 is pushed up by the pressure lever portion 140, so the connecting shaft 51 is positioned in an upper standby position, and the foot pedal 6 is also positioned in an upper standby position. In this state, the sealing portion 130 is not functioning, and the object to be sealed is not sealed.

[0026] In the sealed state, as shown in Figures 6 and 7, by stepping on the foot pedal 6 with the foot, the connecting shaft 51 moves downward to the sealed position, and moves to the sealed position below the rotating roller 53. When this happens, the vicinity of the center of the upper surface of the pressure contact lever part 140, which is in contact with the rotating roller 53, is pressed downward, and the sealing part 130 functions to seal the object to be sealed.

[0027] At this time, the direction in which the foot pedal 6 is pressed and the direction in which the rotary roller 53 moves downward are determined by the connecting shaft 51 and the slide shaft 52, so the rotary roller 53 can be pressed against the pressure lever portion 140 with a strong force without twisting. In addition, since the upper surface of the pressure lever portion 140 comes into contact with the rotary roller 53, it can be pressed down smoothly without any lateral force acting due to friction.

[0028] (effect) Next, the effects achieved by the sealer auxiliary device 2 and the sealer system S of this embodiment will be listed and explained.

[0029] (1) As described above, the sealer auxiliary device 2 of this embodiment is a sealer auxiliary device 2 attached to a tabletop sealer 100 having a main body 110 and a crimping lever 140 that rotates relative to the main body 110, and includes a support base 3 that holds the tabletop sealer 100 at a predetermined height, a stage 4A (4B) attached to the support base 3 and on which an object to be sealed is placed, and a foot pedal 6 slidably attached to the support base 3 and connected to the crimping lever 140 via a connecting shaft 51. With this configuration, an existing tabletop sealer 100 can be converted into a foot-operated sealer with an extremely simple structure.

[0030] (2) The foot pedal 6 is further provided with a slide shaft 52 that is parallel to the connecting shaft 51 that connects the foot pedal 6 and the pressure lever portion 140, and the foot pedal 6 is configured to slide while being guided by both the connecting shaft 51 and the slide shaft 52. In this way, the sliding direction of the foot pedal 6 is restricted by the two shafts, the connecting shaft 51 and the slide shaft 52, which stabilizes the orientation of the foot pedal 6 and makes it easier to transmit force through the rotating roller 53.

[0031] (3) Furthermore, a rotating roller 53 is installed on the pressure lever portion 140 side of the connecting shaft 51 at the contact point with the pressure lever portion 140. Therefore, even if the pressure lever portion 140 oscillates (rotates) and the contact position changes, the pressing force can be transmitted smoothly without receiving a lateral friction load.

[0032] (4) Furthermore, the rotating roller 53 is configured to contact the vicinity of the center of the entire length of the crimping lever portion 140. In other words, if the rotating roller 53 presses the vicinity of the center of the length of the crimping lever portion 140, sealing (welding) can be performed while stabilizing the entire sealer auxiliary device 2, including the support stand 3. In other words, in the case of a manual sealer, the handle 141 is pressed by hand, but in the case of the tabletop sealer 100, the support base portion 33 is located at a high position, so pressing the end portion would create an unnecessary moment, resulting in a lack of stability. Therefore, the vicinity of the center of the crimping lever portion 140 is pressed to stabilize it.

[0033] (5) Furthermore, the stage 4A is installed so that it can slide and rotate relative to the support stand 3 (support stand portion 33), so that by changing the angle and position of the stage 4A, it is possible to create a more comfortable working environment.

[0034] (6) The sealer system S of this embodiment includes the above-mentioned sealer auxiliary device 2 and a tabletop sealer 100 having a main body 110 and a crimping lever 140 that rotates relative to the main body 110. With such a sealer system S, an existing tabletop sealer 100 can be converted into a foot-operated sealer with an extremely simple structure.

[0035] Although one embodiment of the present invention has been described above, the above embodiment shows one application example of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configuration of the above embodiment.
