Description

  The present invention relates to a peeling apparatus and a peeling method, and more particularly to a peeling apparatus and a peeling method for peeling a sheet attached to a substrate from the substrate.

  As a method of peeling the sheet body affixed to the substrate from the substrate, a method of peeling using a claw member that hooks an end of the sheet body has been proposed (Patent Document 1). The one described in Patent Document 1 presses the pressing block against the sheet body, thereby lifting the end portion of the sheet body from the substrate and hooking the floating end portion with the claw member. The claw member is moved in the horizontal direction along the sheet body and peeled off.

  Moreover, a peeling apparatus as shown in FIG. 6 can be proposed. The peeling apparatus includes a vertical movement substrate 2 having a suction head 1, and a hook claw 3 is attached to the vertical movement substrate 2. The hooking claw 3 has flexibility, and includes a base portion 3a extending in the vertical direction and an inclined portion 3b inclined in an oblique direction from the base portion 3a.

  Next, a method for peeling the sheet body 6 stuck on the substrate 5 with such an apparatus will be described. First, as shown in FIG. 6A, the vertically moving substrate 2 is positioned above the substrate 5 to which the sheet body 6 is attached. From this state, the vertically moving substrate 2 is lowered. By this lowering, the suction head 1 is placed on the sheet body 6, and the sheet body 6 is sucked by the suction head 1. In addition, the sloping portion 3b of the hooking claw 3 comes into contact with the substrate 5 by descending, and the vertical movement substrate 2 further descends from this contact state, so that the sloping portion 3b of the hooking claw 3 is bent and the end of the sheet body 6 The part 6a is scooped up as shown in FIG. 6 (b).

  In this state, the sheet body 6 can be peeled from the substrate 5 as shown in FIG.

  However, in the thing of patent document 1, it presses a sheet | seat body from upper direction with a press block, Comprising: The elastic body is made into object as a board | substrate, and the thing of rigid bodies, such as an iron plate, is not made symmetrical. Moreover, it is necessary to float the edge part of a sheet | seat body by the press of a press block, and it becomes difficult to obtain the stable operation | movement. Furthermore, it is necessary to move the pressing block up and down and move the pressing block along the horizontal direction. For this reason, the size of the entire apparatus is increased, and the cost is increased due to complexity.

  Moreover, in the peeling apparatus shown in FIG. 6, hooking of the edge part of a sheet | seat body is performed by the bending of a hooking claw, and this hooking operation is unstable. Also, with the edge part peeled off, the sheet body adsorbed by the adsorption head is lifted up by moving the vertical moving substrate, and at this time, the sheet body may be torn or torn. The peeling work is not stable.

  Therefore, in view of such circumstances, the present invention provides a peeling apparatus and a peeling method that can stably peel a sheet body without being torn or torn.

  The peeling device of the present invention is a peeling device for peeling a sheet body affixed on a substrate from a substrate, and includes a hooking claw member for scooping up at least one side of the sheet body, and the hooking claw member of the sheet body. A claw member drive mechanism that moves forward from one side toward the one side and crawls up one side of the sheet body with a hooking claw member and retracts the claw member from the one side to the outside, and a sheet A suction head for sucking the body, a reciprocating movement of the suction head between one side and the opposite side opposite to this side, and a slide vertical movement mechanism that allows the suction head to move up and down. is there.

  According to the peeling device of the present invention, if the hooking claw member is advanced from the outside of the sheet body toward one side, one side of the sheet body can be scooped up by the hooking claw member. Further, the sheet body can be sucked by the suction head. Furthermore, since the suction head can reciprocate between one side and the opposite side, one side (edge) of the sheet body is scooped up by the hooking claw member, and the sheet is picked up by the suction head. If the suction head is lifted while the body is sucked, the suction head is moved toward the opposite side opposite to the one side by the reaction force from the sheet body with this rise. It will be. Thereby, the sheet body can be peeled off. For this reason, there is no need to move using a suction head that sucks the sheet body, a drive mechanism having a power source, and it is possible to stably peel without applying a large load to the sheet body. it can.

  Even if a plurality of hooking claw members are arranged at a predetermined pitch along one side of the sheet body, they are opposed to each other even if they are respectively arranged on a pair of opposite sides. A plurality may be provided at a predetermined pitch on each side of the pair.

  As described above, in the case where a plurality of hooking claw members are provided, even if the scooping by one hooking claw member fails, the other hooking claw member can scoop up the end of the sheet body. For this reason, the precision of peeling work can be raised.

  In the state where one side of the sheet body is scooped up by the hooking claw member, a blow mechanism for spraying fluid to the scooping portion can be provided.

  The peeling method of the present invention is a peeling method for peeling a sheet body affixed on a substrate from the substrate, and the hooking claw member is advanced from the outside of the sheet body toward one side of the sheet body. The side is hooked up by the claw member, and in this state, the suction head that sucks the sheet body is raised, and the suction head is caused to react to the one side by the reaction force from the sheet body in accordance with this rise. The sheet body is peeled from the substrate while being moved toward the opposite side.

  According to the peeling method of the present invention, if one side of the sheet body is scooped up by the hooking claw member and the suction head that sucks the sheet body is raised in this state, the suction head rises. The suction head is moved toward the opposite side opposite to the one side by the reaction force from the sheet body. Thereby, the sheet body can be peeled off. For this reason, there is no need to move using a suction head that sucks the sheet body, a drive mechanism having a power source, and it is possible to stably peel without applying a large load to the sheet body. it can.

  In this invention, it can peel stably, without applying a big load with respect to a sheet | seat body. For this reason, in the middle of peeling, it can peel stably, without a sheet body tearing or tearing. Moreover, even if the substrate is a rigid body, it can be peeled off.

  Furthermore, the suction head that sucks the sheet body does not need to be moved using a drive mechanism having a power source, and the entire sheet body is not peeled at a time. Do not need. For this reason, simplification, compactness, and cost reduction as an apparatus can be achieved.

  A device provided with a plurality of hooking claws can improve the accuracy of the peeling operation and can improve the workability. In the case where the fluid is sprayed to the scooping portion, one side (end) of the sheet body can be stably pulled away from the substrate by the lifting by the hooking claw member.

A vacuum mechanism (not shown) is connected to the support rod 25. For this reason, when the vacuum mechanism is driven, the inside of the suction head 14 is evacuated, and the work, that is, the sheet body 11 can be sucked to the suction pad 14a. As the vacuum mechanism, a vacuum pump, a vacuum ejector or the like is used. Thus, the suction mechanism 15 can be configured by the suction head 14 and a vacuum mechanism (not shown).

  By the way, the holding plate member 23 includes a rectangular flat plate-like main body portion 23a mounted and fixed to the slide body 22, and a pair of support piece portions 23b extending in the width direction of the base 20 on one short side of the main body portion 23a. 23c. A support rod 25 that supports the suction head 14 is attached.

  In this case, the support piece portions 23c and 23c of the holding plate member 23 facing in the width direction of the base 20 are connected by a connecting body 26 as shown in FIG. For this reason, as shown in FIG. 2, the slide body indicated by 22A1 and 22B1 reciprocates integrally along the guide rails 21 and 21, and the slide body indicated by 22A2 and 22B2 is integrated with each guide rail. Reciprocates along 21 and 21. For this reason, the suction head 14 supported by the support piece portions 23 b and 23 c reciprocates along the guide rails 21 and 21. In this case, the base 20 is provided with cutout portions 28A1, 28A2, 28B1, 28B2, 28C1, and 28C that allow the suction head 14 to reciprocate as shown in FIG.

  A plurality of hooking claw members 12 are arranged at a predetermined pitch along the width direction of the base 20 on both ends in the longitudinal direction of the base 20. As shown in FIG. 2, the predetermined pitch here is P1, which is the pitch between the hooking claw member 12A1 (12A2) and the hooking claw member 12B1 (12B2), and 12B1 (12B2) and the hooking claw member 12C1 (12C2). P2 <P1 <P3, where P2 is an interval pitch of 12C1 (12C2) and an interval pitch between the hooking claw members 12D1 (12D2) is P3. The pitches P1, P2, and P3 can be changed and may be equal.

  As shown in FIGS. 2 and 3, the claw member driving mechanism 13 can be configured by a cylinder mechanism 30 provided at the center in the width direction on both ends in the longitudinal direction of the base 20. The cylinder mechanism 30 includes a cylinder body 31 fixed to the base 20, a rod 32 disposed in a direction parallel to the guide rails 21 and 21, a moving block 33 attached to the rod 32, and a moving block 33. The support 34 is provided. The support 34 includes a substrate portion 34a fixed to the moving block 33, and a support portion 34b that is suspended from the substrate portion 34a and extends in the width direction of the base 20 as shown in FIG.

  A holding piece 35 that holds the claw member 12 is attached to the support portion 34 b of the support body 34. The holding piece 35 includes a vertical wall 35a and a horizontal wall 35b, and the hooking claw member 12 is fixed to the horizontal wall 35b via a fixing tool (bolt member) 36. The hook claw member 12 includes a base portion 37 that is overlapped and fixed to the horizontal wall 35b from below, and an inclined piece portion 38 that extends obliquely downward from the base portion 37. Further, the inclined piece portion 38 is formed with a tapered portion 38a at the tip thereof. The inclination angle θ of the inclined piece 38 is about 45 degrees in this embodiment, but is not limited to this. In other words, it is only necessary to scoop up the short side 11a (11b) of the sheet body 11 as described later. Further, the taper angle α of the taper taper portion 38a can be arbitrarily set. In the illustrated example, the taper angle α is about 110 degrees. However, the taper angle α is not limited to this, and the taper taper portion 38a may be omitted.

  By the way, as shown in FIG. 2, through-holes 40 extending in the width direction are provided at both longitudinal ends of the base 20, and holding pieces 35 are inserted into the through-holes 40, whereby the claw member 12 is attached to the base 20. 20 on the back side.

  Therefore, the holding piece 35 is reciprocated in the directions of arrows A and B (see FIG. 1) by the claw member driving mechanism 13, and the claw member 12 is advanced from the outside of the sheet body 11 toward the side (short side). The side (short side) of the sheet body 11 can be scooped up by the hooking claw member 12, and the hooking claw member 12 can be moved backward from the side (short side) side to the outside.

  The horizontal wall 35 b of the holding piece 35 is provided with a long hole 41 extending in the vertical direction, and the bolt member 42 is screwed to the support portion 34 b of the support body 34 through the long hole 41. As a result, the holding piece 35 can be attached to the support 34. At this time, since the bolt member 42 is inserted through the long hole 41 of the horizontal wall 35b, the vertical height position of the holding piece 35 with respect to the base 20 can be adjusted, and the claw member 12 with respect to the base 20 can be adjusted. The vertical position can be adjusted.

  The material and thickness of the hooking claw member 12 can be variously changed within a range in which the sheet body 11 can be scooped up and stable in strength as will be described later. In this case, those having some flexibility are preferable. Moreover, even if it is uniform as the thickness of the taper taper part 38a, it is good also as a thin wall toward the front-end | tip.

  By the way, this peeling apparatus is provided with a blow mechanism 50 that sprays fluid onto the scooping portion 60 in a state where the end (one side) of the sheet body 11 is scooped up by the hooking claw member 12. The blow mechanism 50 includes a nozzle 51 that blows out fluid (for example, air) and a support body 52 that supports a base portion of the nozzle 51, and air (fluid) is supplied from a fluid source (air source) (not shown). Air (fluid) can be blown out from the nozzle 51. The support body 52 is fixed to the holding piece 35 via a bolt member 53.

  The reciprocating movement of the claw member 12 by the claw member driving mechanism, the vertical movement of the base 20 by the slide vertical movement mechanism, the suction operation of the suction mechanism, and the like can be performed by a control means and a storage means (not shown). The control means is, for example, a microcomputer in which a ROM (Read Only Memory), a RAM (Random Access Memory), and the like are connected to each other via a bus with a central processing unit (CPU) as a center. A storage device as a storage means includes an HDD (Hard Disc Drive), a DVD (Digital Versatile Disk) drive, a CD-R (Compact Disc-Recordable) drive, an EEPROM (Electronically Erasable and Programmable Read Only Memory), or the like. The ROM stores programs executed by the CPU and data.

  Next, a peeling method using the peeling apparatus configured as described above will be described with reference to FIG. The hooking claw members 12 on both ends in the longitudinal direction of the base 20 are positioned slightly outside the short sides 11a and 11b of the sheet body 11, respectively. At this time, as shown in FIG. 1A, the tapered tapered portion 38 a at the tip of the hooking claw member 12 is brought into contact with or close to the substrate 10.

  A pair of suction heads 14 are disposed on both ends in the longitudinal direction of the base 20, and in the initial state, the suction head 14 (14A) on the one short side 11a side of the sheet body 11 is from the short side 11a. Is located on the inner side, and the suction head 14 (14B) on the other short side 11b side of the sheet body 11 is located on the inner side with respect to the short side 11b. As shown in FIG. 1A, the suction pad 14 a of each suction head 14 is placed on the upper surface of the sheet body 11 in the state where the tapered portion 38 a at the tip of the hooking claw member 12 is in contact with or close to the substrate 10. It is made to contact and this sheet 11 is made into the state adsorbed.

  Next, as shown in FIG. 1B, each hooking claw member 12 is moved in the arrow A direction. Thereby, the short sides 11 a and 11 b of the sheet body 11 are scooped up by the inclined piece portion 38 of the hooking claw member 12. Thereby, the upper part 60 is formed on the short sides 11 a and 11 b of the sheet body 11. At this time, the blow mechanism 50 blows fluid (air) against the upper portion 60. Specifically, fluid (air) is sprayed between the upper part 60 and the substrate 10 as shown by an arrow E.

  Thereafter, each suction head 14 is raised by raising the base 20. At this time, the suction head 14 (14A) on one short side 11a side of the sheet body 11 can slide on the other short side 11b side, and the suction head 14 (on the other short side 11b side of the sheet body 11) ( 14B) can slide to one short side 11a. For this reason, with this rise, the suction head 14 is caused by the reaction force from the sheet body 11, and the suction head 14 (14A) on one short side 11a side slides to the other short side 11b side as shown by the arrow F. Then, the suction head 14 (14B) on the other short side 11b side slides to the one short side 11a side as indicated by an arrow F. Thus, the sheet body 11 can be peeled off, and finally, the sheet body 11 can be peeled from the substrate 10. Note that when the peeling operation is completed, the hooking claw member 12 and the suction head 14 are returned to the initial state. In this initial state, the sliding vertical movement mechanism is raised without causing the suction head 14 to suck the sheet body 11 from the state of FIG. 1A, and the hooking claw member 12 and the suction head 14 are moved to the substrate 10 and the sheet body. 11 is a state where the hooking claw member 12 is disposed outside the sheet body 11.

  According to the peeling device of the present invention, when the hooking claw member 12 is advanced from the outside of the sheet body 11 toward one side, one side of the sheet body 11 can be scooped up by the hooking claw member 12. . Further, the sheet body 11 can be sucked by the suction head 14. For this reason, if one side (end part) of the sheet body 11 is scooped up by the hooking claw member 12 and the suction head 14 is lifted while the suction head 14 is attracted, As it rises, the suction head is moved toward the opposite side opposite to the one side by the reaction force from the sheet body 11. Thereby, the sheet body 11 can be peeled off. That is, it is not necessary to move using the suction head that sucks the sheet body 11 and a drive mechanism having a power source, and the sheet body 11 can be stably peeled without applying a large load. Can do.

  For this reason, in this invention, since it can peel stably, without applying a big load with respect to the sheet | seat body 11, in the middle of peeling, the sheet | seat body 11 does not tear or tear, but is stable. Can be peeled off. Moreover, even if the substrate 11 is a rigid body, it can be peeled off. Furthermore, the suction head 14 that sucks the sheet body 11 does not need to be moved using a drive mechanism having a power source, and the entire sheet body is not peeled at a time. Does not require large adsorption power. For this reason, simplification, compactness, and cost reduction as an apparatus can be achieved.

  As in the above-described embodiment, in the case where a plurality of hooking claw members 12 are provided, even if the scooping by one hooking claw member 12 fails, the other hooking claw member 12 scoops up the end of the sheet body 11. can do. For this reason, the precision of peeling work can be raised and workability | operativity can be improved.

  The fluid can be sprayed to the scooping portion 60, and one side (end portion) of the sheet body 11 can be stably pulled away from the substrate 10 by the hooking claw member 12.

  As described above, the embodiment of the present invention has been described. However, various modifications are possible without being limited to the above-described embodiment. For example, the sheet body 11 may be any one having flexibility. It may be made of paper, resin, or the like, and the size, shape, and thickness of the sheet body 11 can be arbitrarily set within a range that can be peeled by the peeling device according to the present invention. For this reason, it is not specified as an application of the sheet body 11. In the above-described embodiment, the substrate 10 is configured by a rigid body such as an iron plate. However, the substrate 10 may be configured by a flexible or cushioning material instead of a rigid body.

  In the above-described embodiment, the hooking claw member 12 is disposed on both short sides 11a and 11b. However, the hooking claw member 12 may be provided only on one of the short sides 11a (11b). Also, the number of hooking claw members 12 disposed on can be arbitrarily set according to the size, material, and the like of the sheet body 11.

  Further, in the above-described embodiment, the suction heads 14 are arranged in pairs on the both short sides 11a and 11b, but the number of the arrangement is arbitrary, and the hooking claw member 12 is arranged. There should be at least one on the side. The fluid blown out by the blow mechanism 50 may be a gas such as nitrogen gas or oxygen gas, or a liquid such as water. That is, various fluids can be used depending on the type of the adhesive or pressure-sensitive adhesive for attaching the material of the sheet body 11 to be peeled off or the sheet body 11 to the substrate 10.

  In the embodiment, after the sheet body 11 is peeled off, the suction head 14 is in the state of approaching the center of the substrate 10. Therefore, when the sheet body 11 is peeled next, the sheet body 11 is returned to the initial state (the state where the suction heads 14 and 14 are positioned on the both short sides 11a and 11b side of the sheet body 11 as shown in FIG. 1A). There is a need. For this reason, the operator may return to this state, but a return mechanism may be provided. As the return mechanism, various reciprocating mechanisms such as a cylinder mechanism and a ball nut mechanism can be adopted. In this case, one cylinder mechanism or the like can be arranged on each holding plate 23. Further, the reciprocating mechanism needs to be in a position and a state (for example, a state where the pressing lot is free) that does not hinder the movement of the suction head 14 during the peeling operation of the sheet body 11.
