Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention cuts and supplies an adhesive elastic body made of a foamed resin material used as a sealing material or a vibration-proof material to a predetermined length. To a device that 2. Description of the Related Art Conventionally, as a fixed-size cutting supply apparatus which cuts and supplies an adhesive elastic body to a predetermined size and length, a cutting apparatus which cuts and supplies the whole separator has been put to practical use. . [0003] However, in the conventional fixed-size cutting supply apparatus, it is necessary for an operator to perform a troublesome operation of peeling off the separator from the fixed-size cut adhesive elastic body. Therefore, it takes time and troubles to improve the efficiency of the entire attaching operation. The present invention has been made in view of such a point, and an object of the present invention is to make it possible to easily supply only an adhesive elastic body cut to a fixed size. [0005] In order to achieve the above object, the present invention has the following arrangement. In other words, the invention according to claim 1 is a transport mechanism that causes a continuous belt-shaped adhesive elastic body with a separator fed from a raw roll to travel along a predetermined transport path, and cuts only the adhesive elastic body in the middle of the transport path. A separating mechanism that separates the separator from the adhesive elastic body at the end of the transport path and winds the separator in a direction significantly different from the transport path, and a transport mechanism that performs transport of the adhesive elastic body for a set length. Control means for stopping the cutting mechanism and operating the cutting mechanism , and a cutting portion for cutting only the adhesive elastic body
Then, the separator was temporarily peeled off from the adhesive elastic body
After that, preliminary separation of the separator to be bonded to the cut adhesive elastic body
It is characterized by having a separation mechanism . According to the structure of the first aspect of the present invention, the adhesive elastic body with the separator, which is unwound from the raw roll, travels along a predetermined transport path, and is transported by a predetermined length. When this operation is performed, the conveyance is stopped and only the adhesive elastic body is cut in the middle of the conveyance path. As the conveyance proceeds, a part of the front end side of the adhesive elastic body protrudes from the end of the conveyance path, but the separator portion of the protruding adhesive elastic body portion is separated from the adhesive elastic body at the end of the conveyance path, and the adhesive elastic body is removed. The sheet is conveyed by being rolled in a direction largely different from the feeding direction. Therefore, only the adhesive elastic body protrudes from the end of the transport path, and the operator picks up the adhesive elastic body portion protruding from the end of the transport path, thereby removing the adhesive remaining on the transport path. The elastic portion can be taken out while peeling from the separator. Further, since the separator in the cleavage site is separated from the temporarily tacky elastic body, without touching the separator be allowed to penetrate the cutter into the adhesive elastic body at the time of cutting, it is never scratched separator. In addition, since the peeled separator is joined again to the cut adhesive elastic body, the re-joining force is smaller than the initial joining force, and the separated elastic adhesive body is removed from the separator when the fixed-size cut adhesive elastic body is taken out. Can be easily removed lightly. FIG. 1 shows an entire side view of a fixed-size cutting and feeding apparatus according to the present invention. The fixed-size cutting and feeding device includes an adhesive elastic body 1 with a separator fed from a raw roll 2.
Transport mechanism 3 for traveling along a horizontal transport path A,
A cutting mechanism 4 that cuts only the adhesive elastic body 1 in the middle of the transport path A, and a separator preparator that temporarily separates the separator s from the adhesive elastic body 1 at this cut portion and then joins the separator s to the cut adhesive elastic body 1 A peeling mechanism 5, a separator peeling and collecting mechanism 6 that peels the separator s from the adhesive elastic body 1 at the end of the transport path A and winds the separator s in a direction substantially different from the transport path A, a counter for setting a cutting length, a transport control circuit, and the like. And a control panel 7 equipped with a caster mounted on a movable cart 8 with casters. As shown in FIG. 1 and the side view of FIG.
The transport mechanism 3 includes a pinch roller 11 driven by a stepping motor 9 via a toothed belt 10, and a pressing roller 12 arranged opposite to the pinch roller 11 so as to be adjustable in height. The stretched adhesive elastic body 1
Is sandwiched between the pinch roller 11 and the pressing roller 12 with the separator s facing down, and is sent to the left in the figure. The cutting mechanism 4 is, as shown in FIGS. 1 and 3, a cutter holder 14 slidable along a pair of upper and lower rails 13 laid on a transport path A, and is freely rotatable on the cutter holder 14. The chain 16 connected to the cutter holder 14 is driven forward and reverse by a motor 17 so that the disk cutter 15 travels directly across the transport path A. I have. The separator preliminary peeling mechanism 5 is shown in FIG.
As shown in FIG. 3, a pair of guide rollers 18 and 19 located before and after a cutting position C (see FIG. 4A) below the transport path A, and a peeling roller 20 disposed below the pair of guide rollers 18 and 19. , The separator s located on the lower surface of the adhesive elastic body 1 is once peeled, wound around the guide rollers 18, 19 and the peeling roller 20, guided and run, and the lower surface of the adhesive elastic body 1 is again located below the cutting position. The separator s is bonded to the (adhesive surface). The separator separation and recovery mechanism 6 is configured to guide the separator s separated from the adhesive elastic body 1 at the end of the transport path A downward through the end guide roller 21 and wind it around the collection roller 22. The collection roller 22 is linked to the stepping motor 9 via a toothed belt 23 and gears 24 and 25, and the maximum winding torque of the collection roller 22 is set to the powder mounted on the gear 24. It is set by the clutch 26. The fixed-size cutting supply apparatus of the present invention is configured as described above, and its operation will be described below with reference to FIG. Here, it is assumed that the cutting length L of the adhesive elastic body 1 is set shorter than the length from the cutting position C to the end position of the transport path A. FIG. 4A shows an initial state in which the adhesive elastic body 1 cut to the fixed size is sent out. The tip of the adhesive elastic body 1 protrudes from the end of the transport path A, and the cut a of the adhesive elastic body 1 Is located between the cutting position C and the end position of the transport path A. At this time, the separator s has already been peeled off from the portion of the adhesive elastic body 1 protruding from the end of the transport path A. At this time, the optical sensor 26 provided at the end of the transport path A detects the presence of the adhesive elastic body 1 protruding from the end of the transport path A. As shown in FIG. 4B, when the operator picks up the tip of the adhesive elastic body 1, the optical sensor 26 detects this and activates the transport mechanism 3, and the adhesive elastic body 1 is moved forward. Conveyed. Then, the worker can peel off the adhesive elastic body 1a cut to the fixed size from the separator and pull out the adhesive elastic body 1 by pulling up the adhesive elastic body 1 in response to the sending. At this time, loosening of the separator s occurs with the feeding of the adhesive elastic body 1, and the collecting roller 22 of the separator peeling and collecting mechanism 6 operates to take up the loosening. The feed amount of the adhesive elastic body 1 is counted as the rotation amount (the number of output pulses) of the stepping motor 9 by the transfer control circuit unit housed in the operation panel 7, and FIG.
As shown in (c), when the feeding of the set length is completed, the stepping motor 9 stops. Then, subsequently, the cutting mechanism 4 operates to cut the adhesive elastic body 1. After the cutting is completed, the transport mechanism 3 is activated again, the adhesive elastic body 1 is transported forward, and the loosened separator s is taken up and collected. Then, the leading end of the adhesive elastic body 1 projects from the end of the transport path A, and the optical sensor 26 detects the arrival of the adhesive elastic body 1, so that the delivery mechanism 3 stops,
The original state shown in FIG. This completes one fixed-size cutting and feeding, and thereafter, the above operation is repeated with the removal of the fixed-size cut elastic elastic body 1a. FIG. 5 shows an initial state in which the cut length of the adhesive elastic body 1 is set to be longer than the length from the cut position C to the end position of the transport path A. In this case, the fixed length cut is performed. When the adhesive elastic body 1a is removed, the next conveyance is started in the same manner as in the previous example. However, even if the tip of the adhesive elastic body 1 is detected by the optical sensor 26, the feeding is not stopped, and the set length is set. At the point in time when the number of feeds is counted, the conveyance is stopped and the operation shifts to the cutting operation. That is, the stop of the transport mechanism 3 is set so that the fixed-size delivery is prioritized. The present invention can be implemented in the following modes. The disk cutter 15 of the cutting mechanism 4 may be rotationally driven. The cutting operation of the disk cutter 15 may be performed by reciprocating to make one cutting operation, or one cutting operation may be performed in each of the forward movement and the backward movement. As the cutting mechanism 4, besides using the disk cutter 15 traversing left and right as described above, a hot wire cutter traversing the transport path A may be horizontally arranged so as to be vertically movable. . In this case, if a paper material that is not melted and cut by the hot-wire cutter is used for the separator s, only the adhesive elastic body 1 can be cut without the separator preliminary peeling mechanism 5. To configure the transport mechanism 3, a transport path A
The separator s peeled off at the terminal end may be forcibly transported and the adhesive elastic body 1 may be transported. In this case, the transporting mechanism 3 also serves as the separator peeling and collecting mechanism 6. To start the transport mechanism 3, a start command can be issued by a manual or foot-operated switch dedicated to starting. As is apparent from the above description, the following effects can be obtained according to the present invention. That is, according to the first aspect of the present invention, the operator can take out the adhesive elastic body cut to a predetermined length simply by picking up the adhesive elastic body portion protruding from the end of the transport path, and peel off the separator one by one. No labor is required, and the efficiency of the sticking operation can be improved. According to the first aspect of the present invention, it is possible to easily and surely cut the adhesive elastic body without damaging the separator, and to remove the adhesive elastic body portion protruding from the end of the transport path. Separation from the separator was easy and easy, and handleability was further improved.
