[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a press device having a scrap processing function.

[0002]

[Prior art]

 In the pressing machine, the upper and lower molds press the film to form holes of a predetermined shape in the film that is intermittently conveyed between them, and the scraps generated by this are sucked by the blower drive. Some of them are designed to be installed in the scrap box. The reason for sucking the scraps and introducing them into the scraps tank is that if the scraps adhere to the film after the pressing operation, it will interfere with the next process, so that the scraps can be reliably removed from the film. This is because the scraps are gathered in one place to facilitate the collection.

FIG. 2 shows a schematic configuration of an example of such a conventional pressing apparatus. In this pressing device, the upper mold 1 and the lower mold 2 press the film 3 to intermittently convey the film 3 between them to form holes of a predetermined shape, and the scraps 4 generated by this are blower 5 It is designed to be sucked and introduced into the scrap waste tank 6 by the driving. Of these, the scrap waste tank 6 has a structure in which an upper portion of a bottomed cylindrical lower tank 8 is detachably attached to a lower portion of a headed cylindrical upper tank 7 by a screw method. An intake hole 9 is provided at a predetermined portion of the upper tank 7. The intake hole 9 is connected through a duct 12 to an exhaust hole 11 provided at a predetermined location of a temporary waste container storage chamber 10 provided in the lower mold 2. An exhaust hole 13 is provided at another predetermined position of the upper tank 7. The exhaust hole 13 is connected to the blower 5 via a duct 14. The blower 5 is connected to a power source (not shown) via a cord 15 and a plug 16. A headed cylindrical member 17 is provided in an upper part of the removed dust tank 6, and an upper part of a removed dust separation filter 18 formed of a bottomed tubular mesh member is attached to a lower portion of the headed cylindrical member 17. . An exhaust hole 19 is provided at a predetermined position of the headed cylindrical member 17. The exhaust hole 19 is connected to the exhaust hole 13 of the upper tank 7 via a duct 20.

In this press device, when the blower 5 is driven, the inside of the scrap residue tank 6 including the inside of the headed cylindrical member 17 becomes negative pressure, and further, the inside of the temporary scrap waste container chamber 10 of the lower mold 2 becomes negative pressure. Then, the punched waste 4 generated by the pressing action of the upper die 1 and the lower die 2 is sucked into the punched waste temporary storage chamber 10 of the lower die 2 and further introduced into the punched waste tank 6 through the duct 12. . In this case, the air in the waste dust tank 6 passes through the waste dust separation filter 18, is sucked into the headed cylindrical member 17, and is further discharged to the atmosphere through the ducts 20 and 14 and the blower 5 in order. The scraps 4 introduced into the scraps tank 6 cannot pass through the scraps separation filter 18, and are adsorbed to the outer surface of the scraps separation filter 18 and retained in the scraps tank 6. As a result, when the blower 5 is stopped, the scraps 4 adsorbed on the outer surface of the scraps separation filter 18 and retained in the scraps tank 6 naturally fall and are collected at the bottom of the lower tank 8. . Therefore, the scraps 4 can be reliably removed from the film 3, and the scraps 4 can be collected in one place, that is, at the bottom of the removable lower tank 8 to facilitate the recovery thereof.

[0005]

[Problems to be solved by the device]

 By the way, in such a conventional press device, when the blower 5 is driven again in a state where the scraps 4 are collected at the bottom of the lower tank 8, the air in the scraps tank 6 is sucked from the exhaust hole 13 by the blower 5. As a result, together with the sucked air, the scraps 4 gathered at the bottom of the lower tank 8 rise up and are adsorbed to the outer surface of the scrap separation filter 18, resulting in a decrease in suction force and extraction. The waste 4 cannot be reliably removed from the film 3. In order to avoid such a situation, the lower tank 8 may be removed and the scraps 4 therein may be collected. However, the suction force is reduced even when the amount of the scraps 4 stored in the lower tank 8 is relatively small. Therefore, the scraps are collected frequently, and therefore the scraps are collected. Not only is the work troublesome, but since the press machine must be stopped each time, there was the problem that the operating rate declined. An object of the present invention is to provide a press device capable of maintaining a constant suction force even if the amount of scraps contained in the lower tank increases to some extent.

[0006]

[Means for Solving the Problems]

 In this invention, the scraps generated by the pressing action of the upper die and the lower mold are sucked by the drive of the blower and introduced into the scrap waste tank, and the introduced scraps are provided in the scrap waste tank described above. In a press device configured to be retained in the removal cast by a waste separation filter, the removal waste tank is an upper tank, a lower tank detachably attached to a lower portion of the upper tank, the lower tank and the upper tank. It is composed of a mortar-shaped separating wall having a large number of air passage holes provided between it and the tank, and a scrap residue passage hole is provided at the center of the separation wall, and the scrap residue is provided in the upper tank. A separation filter is provided to remove the scraps retained in the upper tank by the scraps separation filter from the separation wall. Is obtained so as to fall naturally in said lower tank through the slag passage hole.

[0007]

[Action]

 According to this invention, the scraps retained in the upper tank by the scraps separating filter are naturally dropped into the lower tank through the scraps passing hole provided at the center of the mortar-shaped separating wall. Therefore, the blower is driven again in the condition that the scraps are collected in the lower tank, and even if the scraps collected in the lower tank rise, the separation wall has a mortar with a large number of air passage holes. Since it is made into a shape, it is possible to make it difficult for the raised scraps to pass through the scrap residue passage hole provided in the center of the separation wall, and as a result, the scraps once collected in the lower tank are removed. It is possible to prevent the dust from being almost adsorbed to the outer surface of the dust separation filter, so that the suction force can be kept constant even if the amount of waste dust stored in the lower tank increases to some extent. One can be.

[Embodiment] FIG. 1 shows a schematic configuration of a pressing apparatus according to an embodiment of the present invention. In this figure, the same reference numerals are given to the same names as those in FIG. 2, and the description thereof will be appropriately omitted. The vertical size of the upper tank 7 of this pressing device is substantially the same as the vertical size of the scrap residue tank 6 of the conventional pressing device shown in FIG. 17 and a scrap residue separation filter 18 are provided. A mortar-shaped separating wall 21 is provided below the upper tank 7. That is, the separation wall 21 is provided between the upper tank 7 and the lower tank 8 which is detachably attached to the lower portion of the upper tank 7. At the center of the separation wall 21, a punched dust passage hole 22 that is somewhat larger than the punched dust 4 is provided, and a number of air passage holes 23 that are smaller than the size of the punched dust 4 are provided around the punched dust passage hole 22. A relay 24 is provided in the middle of the cord 15. This relay 24 is turned on when the film 3 which is intermittently conveyed is conveyed, that is, when the film 3 is not pressed, it is in an off state, and when the film 3 is stopped, that is, when it is pressed, it is in an on state. It is supposed to be replaced.

In this pressing device, when the film 3 is stopped and pressing is performed, the relay 24 is in the ON state and the blower 5 is driven. When the blower 5 is driven, the inside of the upper tank 7 including the inside of the headed cylindrical member 17 becomes negative pressure (the lower tank 8 will be described later), and the inside of the temporary scrap removal container chamber 10 of the lower mold 2 becomes negative. It becomes pressure. Then, the scraps 4 generated by the pressing action of the upper mold 1 and the lower mold 2 are sucked into the temporary scrap storage chamber 10 of the lower mold 2 and further introduced into the upper tank 7 through the duct 12. It In this case, as in the conventional case, the air in the upper tank 7 passes through the exhaust gas separation filter 18 and is sucked into the headed cylindrical member 17, and further passes through the ducts 20 and 14 and the blower 5 in this order to the atmosphere. However, the scraps 4 introduced into the upper tank 7 cannot pass through the scrap separation filter 18 and are adsorbed by the outer surface of the scrap separation filter 18 to be stored in the upper tank 7. Can be fastened.

When the film 3 starts to be conveyed after the pressing is finished, the relay 24 is turned off and the blower 5 is stopped. When the blower 5 is stopped, the suction through the scrap passing hole 22 is stopped. Then, the scraps 4 adsorbed on the outside surface of the scraps separation filter 18 and retained in the upper tank 7 naturally fall and drop on the upper surface of the separation wall 22, and slide down on the upper surface of the separation wall 22. It is collected in the central portion, naturally falls into the lower tank 8 through the scrap residue passing hole 22, and is collected in the bottom portion in the lower tank 8.

Next, when the blower 5 is driven again and the inside of the upper tank 7 becomes negative pressure, the inside of the lower tank 8 also becomes negative pressure. In this case, the air in the lower tank 8 is discharged into the upper tank 7 through the drained dust passage hole 22 and the many air passage holes 23. Therefore, even if the punched dust 4 collected in the lower tank 8 rises up due to this air flow, the raised dusted dust 4 does not concentrate in the punched dust passage hole 22 and a large number of air passage holes are formed. 23 will be distributed. Therefore, it is possible to prevent the raised scraps 4 from almost passing through the scrap passage hole 22 provided at the center of the mortar-shaped separation wall 21, and as a result, collect them once in the lower tank 8. It is possible to prevent the removed scraps 4 adsorbed on the outer surface of the removed waste separation filter 18 from being almost absorbed. Therefore, even if the amount of the scraps 4 accommodated in the lower tank 8 is large, the suction force is increased. Can be kept constant.

[0012]

[Effect of device]

 As described above, according to the present invention, the suction force can be kept constant even if the amount of the scraps contained in the lower tank increases to some extent. Therefore, the work of collecting scraps can be simplified, and the operating rate of the press machine can be improved.
